I’ve mentioned this electric sheep screen saver. Here’s one mpg from it.

I may find a way to batch convert them and incorporate them into the blog design. That won’t make it impossible for you to read.. :) Click either “play now” or “play in popup” to see it. If either of those don’t work, click the download link and have a look at it in Windows Media Player.

The screen saver has downloaded a bajillion of these goodies into its cache on my machine. Eye candy. I think this one is morphing between four different “sheep” IDs.

More on Truth

Awful Stuff, Techie Stuff, blather, philosophy No Comments »

Referring to the previous entry, good luck with the truth anyway if the internets are against you.

Wow.  Bizarre twists on meaning become dominant and obliterate everything else.

(Except for one brilliant article pointed it out, and I’m posting about it, and you’re reading it.  Maybe it is always free or bound to be free.)

The Windows People on Strong Truth

Ah ha ha!

The truth will make us strong.”

I’m waiting for more.  Please.  Feed me another verse.  I’ll start compiling it into a Windows Bible.  Not that there isn’t at least one already.

More test video - Flash vs. Quicktime at x720- resolutions

Film, Techie Stuff No Comments »

At the same image resolution, Flash’ latest codec (On2 Vp6) at best quality produces ten times smaller file sizes than Quicktime! Sheesh! If the image quality is the same, Flash clearly wins for file size. As for audio, Flash uses an mp3 codec (I don’t know which) and Quicktime won’t - I’m using AAC. I’m guessing Flash uses LAME, and if this codec sound quality test is a good guide, audio quality between them is the same (usually excellent at ~192kbps).

The following clips alternate Quicktime and Flash format at the same resolutions, lower resolution each round. I’d like to know how these load for you and how you think the formats compare in appearance.

The last video in my last post should be the first in this, as I’m comparing it now to the same resolution (720×540) in Flash format. Please watch it again (link) before watching the first video in the following list. Then for each in the list except the last two, I suggest clicking “play in popup window”.

Four Quicktime HD export test clips

Film, Techie Stuff 1 Comment »

The end of this entry has buttons and links to play any of four different test clips (each of a bird and/or my son “Mago”).  I’d use the “play in popup” link first, starting with the last (the smallest).

The first clip is 1920 horizontal lines by 1080 vertical lines in the Sorensen 3 codec and some blah (I’m guessing) audio codec (Sony Vegas Pro lets me export to Quicktime, but not with AAC. Why?).

The second clip is 1920 x 1080 by Quicktime Pro (from an uncompressed .avi I exported from Vegas) with the H.264 codec (It seems that’s Apple’s newest video codec? - which I’m only guessing gets better mileage than Sorensen 3?) and with AAC audio at 192 Khz.

Both those files are blasted huge (45 to 55MB for a few seconds!?), so I’m realizing I just gotta sacrifice some video and audio quality for more compression..

The third clip uses Sorensen 3 and some crummy audio at 1280 x 720 resolution.

The fourth uses H.264 and AAC (like the second) and is 720 x 540.

Again, click “play in popup” to play any of these - I suggest the last one first - I wonder if the others will even load without a lot of patience..

For anyone curious I’ve started putting up notes on video encoding/distribution in my wiki (more - maybe a lot more - could aggregate there over time - I’ll see. The page title is far broader than the video notes there now).

The Electric Sheep Screen-saver

Good stuff, Techie Stuff, art No Comments »

I ran across this today and tried it - so worth it.

It’s a screen-saver that does mutating, “genetic” computer-generated animated art for your screen-saver, and distributes these across the internet to everyone else who has the screen-saver installed, and users can vote for or against the various “electric sheep” (up arrow key votes yes, down votes no) so that cooler ones get promoted.  I took the following image from the sites gallery of current images (which fluctuates - they render new “sheep” images from user’s machines during idle time/bandwidth) and scaled it up - it’s a desktop now.

This is a link to the image because the thumbnail isn’t working for some reason.

I love that MATRIX screen-saver I found and will probably go back to it from time to time.  Meanwhile, this.

Adobe “Safecast” spyware shut down my legal photoshop install

Awful Stuff, Hackles, Techie Stuff 2 Comments »

My wife has a legal copy of Adobe CS2 purchased from BYU Bookstore when she was a student at BYU.

Today, mysteriously, every time Photoshop would boot up it would close automatically, no questions asked, no statements made, no crash - just.. gone.

Exasperated that reinstalling it and several other things didn’t fix it, I started looking through Windows system services one by one, googling them, and shutting down ones that I don’t want (I want a way to make those not start - there must be some kind of service blocker tool out there..). I ran across one entitled “Adobe LM Service”, which starts automatically at system boot, and googled it. I found this page, which informs me that the cause of the problem is spyware - which was installed by Adobe with CS2.  It says: show

Mother - Game Over - Remix

Music, Music I wrote, Techie Stuff, Video Games 3 Comments »

There’s this tune from the game Mother (the original Nintendo version of what later became the brilliant EARTHBOUND on Super Nintendo), evidently this is the music when you die. (Or that’s what the track ripper says; “Game Over”: I wouldn’t know because I never played the original. Also, the music when you die in EARTHBOUND is different but equally cool.) One day I was listening to this tune and I heard and started singing a high harmony melody. I’ve now re-rendered the music to include that melody, also altering the bass line enough that I can call this an original - if blatantly ripped off and extended - work, without conscience - so you can download it.

(Download mp3, ~1.7MB)

How I made this was tricky - and yet produced results far faster than if I’d figured and re-did all the notes by hand. I’m kinda proud of it. I’ve mentioned Melodyne, which changes pitches very well. I used a Winamp plugin called NotSoFatso that lets you mute tracks in an .nsf (emulated nintendo music) file. I rendered each part (or instrument or harmony) to different wave files via Winamp’s wave writer - bass, lead, and lead echo. That was easier with NotSoFatso allowing me to “shadow” or list one of so many songs in the .nsf (right-click the song listing, click “file info”, then click “shadow->Winamp). I moved the notes of the bass wave file around a bit in Melodyne, and also copied it to another track and divided and moved around the notes and overtones (formants) to make this higher lead part (several of the notes were barely audible until I moved the formants).

Bingo.

Melodyne gave it a sing-song quality, if it is still very much a “nintendo” instrument - because Melodyne is designed to emulate the formants of the human voice in particular. It also made it too “clean” to be a “nintendo” instrument, so I processed the result in Audio Mulch using a “DigiGrunge” distortion decimator simulating a bit depth of 8. Then I mixed it all back together in Guitar Tracks Pro 3, and converted it to .mp3 with foobar2000’s “convert to same directory” right-click option.

Digital Cinema Dreams

Film, Goings-on, Good stuff, Star Wars, Techie Stuff No Comments »

[Update Jun 1st: there were several inaccuracies in this article now corrected, and I’ve added some too - all in bold.]

I just ordered a Canon VIXIA HD30 camcorder - this is a higher end HD consumer beast. I’m excited about it. There are many things I’ll do with it.

I’ve been asking around and doing a lot of research about HD and particularly how it may transfer to film and/or project on a big screen, and I want to say I notice a fairly sharp divide between people who insist video should never imitate or copy to film vs. people who say go for it. What’s odd to me is that folks against it seem to usually describe that as the more realistic or practical approach, or that copying video to film is only “dreaming.”

Well, gee, imagine any film maker dreaming.

I’m in no mood after writing my thesis :) to cite the sources of facts I present and form my conclusions on. Suffice it to say I believe you could verify these facts.

My take is that in truth it is more practical to go digital if you can. We are in a digital cinema revolution, and physical film stock may always have its place, but the reality is that the blockades to shooting digital film which audiences don’t perceive as different after transfer to film - never mind the options to just distribute digitally increasing every year! - blockades to that quality break down steadily every year.

[Why am I speculating? With a ruler I drew a grid on a post-it note at the resolution of HD - 3 pixels an inch assuming a 30 foot screen - and filled it with alternating black-and-white squares, and looked at it from 40 feet back. There would really need to do be some image processing and projection magic with the way pixels transition into each other to make it look good. Fairly obvious “I am pixels” look at that resolution. But I need to know. I’m looking for sources that give a lot more detail on this, and I’ve also simply got to do real application visual tests on all this theory myself, somehow.]

About digital film projection, I’m going to speculate now. I don’t know how this actually plays out, this is theory, and I’d love to know of the real-world tests that certainly are playing out on these questions. But my speculation is that depending, digitally projected high-definition video could look not only anywhere from sufficiently as good as film to just as good, but better. Consider resolution available from the Red One. Here’s a picture of a 2006 model with some kind of super-exo-death-armature-skeleton-frame thing around it.

………………..

[This section had inaccuracies about the resolution of the Red One when I first wrote it - it’s fixed now.]

It shoots 2k (just over 1080 vertical pixels). That’s a bit more resolution than George Lucas thought was good enough (snobs have turned against him after the Star Wars prequels - yes, I will make that abusive statement, anyone who derides Lucas over his Star Wars prequels is a snob - I have qualms with the stories and writing on Star Wars Episodes I, II, sorta III and totally VI, but IV and V still rock the world, and I give Lucas full faith as a technological pioneer: arguably, he has single-handedly initiated the special effects revolution, and then the digital cinema revolution. Whether he simply vanishes like a good Jedi or makes it to heaven or not, before and if you pass the pearly gates, you’ll at least have to give him a hearty “thank you”.) Never mind that the Red One looks like a Star Wars Tie Fighter or something, and has a name reminiscent of Luke Skywalker flying the Death Star trenches - they have their market down - but it can record 1152 vertical pixels (or rows) at 120 frames a second, so that if projected at the same rate, it’s showing images exactly five times the frequency of standard film. I’ve read of tests going back to the 1970s demonstrating that people see a difference between 24 frames a second vs. 60 frames a second, and 120 is twice the upper range of those tests. I’d think that would probably look brilliant. Or you can do about a five hundred more rows of pixels at 60 frames a second, or again about five hundred more than that (or 2048 rows) at 30 frames a second - still a better frame rate than film. And digital projectors that do this are steadily spreading to theaters worldwide - my dear local Wynnsong has some now :)

Interesting math: that highest resolution mentioned (4x) has 4,096 vertical pixels, and if you divide that into 30 feet (for the typical height of a theater screen, and that link passes those paramaters into google calculator), and express that in inches, it’s about 8 pixels an inch. The math for x1080 resolution gives 3.333… pixels an inch. How does that look when you’re sitting 30 or 40 feet back (or further) from the screen? Losing detail and size for distance, they’d likely appear a lot finer and closer together I’d think. How does the density of pixels multiply across the visual range with distance? [When I first posted this I wondered if ten inches would shrink to 1, visually, so that what used to look like 3 pixels in an inch would be 30, and whether that would be enough - but no, 300 pixels an inch (or 100 times as many as 3 per inch) would correlate with the usual baseline for digital images.] That would seem like a reasonable baseline they’d go for in apparent density for “digital film”. If the visual density multiplies by about a hundred - would it? - I haven’t done that math or looked it up - but if that were the case then x2 resolution might be effectively 600 dots per inch, and x4 resolution maybe 1200 dots per inch?]

I’ve read of cinema house worries over the fickle and perhaps difficult to manage aspects of digital media, and there may be a lot of kinks and things to figure out with digital cinema along the way - but what do we expect? - it’s a brand new medium. Besides, those kinks will probably be worked out fairly fast. It took a good 60 or 70 years or so to figure out how best to technically work film, but vast improvements with digital film are advancing over stages of years, not decades! Ten years ago nobody would have thought you could buy a camera that shot at 1080 vertical pixels for under a thousand dollars. Three years ago the same camera would have cost several thousand dollars. If the trend continues the same quality camera will be available in a few years for half the price, and a camera twice as good will be available at the same price. Expanding that trend to decades it’s easy that around, say, 2020, teenagers from middle to low income families could be armed with camcorders that shoot at a resolution you can blow up to an IMAX screen - and by then there may be some bid-to-rent digital distribution network in place so that they can show their independent film at a local theatre for costs low enough that independent filmmakers of today might gasp. You can distribute for what cost? That low?

That all sounds like a dream, and it could be, but again, given the way these specific technologies have advanced in the past decade it’s easy they may advance to that stage in another decade. In my book digital cinema has to be the way motion pictures go. (I think high definition and beyond will also radically transform home entertainment.) We’ll still use film a lot, I think, especially for long-term storage because digital storage is notoriously destructible and fickle.

Old Wordpress entries imported - a forgettable tech log

Techie Stuff No Comments »

For a few months this whole blog was down and only recently I just made a new blog here and posted new entries. Well I finally got the entries from the old blog out of the backed up database. What made the blog break? It was auto-installed by a tool at my domain called “Fantastico”, which kept nagging me to upgrade to the latest wordpress for security reasons. I think it was incompatibilities with the style that made everything completely dysfunctional after I upgraded. I couldn’t get it working with other templates either. I don’t know what the deal was. I couldn’t login to the blog admin; I couldn’t do anything. Totally baffling.

It would have been way simpler to use Wordpress’ export feature and just get all the entries in an .xml importable file. How did I get the old entries back from the database? show

The Wilhelm Scream -> The Dean Scream? (I have a Scream!)

Film, Good stuff, Star Wars, Techie Stuff, blather No Comments »

[UPDATE: the original of this post suggested using the “Dean Scream” in entertainment projects, and failed also to credit and link to a fellow from whose page I obtained a copy of the “Wilhelm Scream”. I’ve learned that the “Dean Scream” most probably is not necessarily in the clear for use in entertainment projects - which is too bad :) ]

(Close your eyes when it turns black and white with Uma Thurman slashing a sword, and when someone pulls out a knife. Unless you aren’t squeamish or don’t hate gratuitous violence.)

This is another of at least a few videos posted at YouTube showcasing the myriad uses in films of a stock sound originating at Warner Bros. in 1951, eventually dubbed by Ben Burtt the “Wilhelm Scream”.

Yes, it is actually used in all those shows and films. This isn’t some weird dub-over of them (I was really surprised and amused to learn it was used in THE LORD OF THE RINGS films two and three).

I found a wave file of the “classic” Wilhelm Scream apparently directly copied from the original take :) Here it is. Click. Click. Click.

(That’s an mp3 burn of the sound)

You can also hear the sound at sound designer Steve Lee’s web site, hollywoodlostandfound.net (this is where I grabbed the sound from), and read a detailed history of it there.

At that page and in an interview with a director (in addition to Steve Lee) in this YouTube video, I’ve learned that the man who popularized the sound, Designer Ben Burtt, will no longer be using the sound (he used it in all six Star Wars films). My blunt take: the public has caught on to the “secret” of its use - previously, mostly an in-joke between many sound designers - so now, it’s, like, popular. And the first rule of hard-core Nerddom is that if it’s popular, it isn’t “cool” anymore.

I think that’s a silly decision on Ben Burtt’s part (I only speculate, perhaps unfairly, on his reasons).

I emailed Steve Lee about the legality of using the Wilhelm Scream - in a nutshell no one knows for sure who the original artist is, and while technically it is owned by Warner Bros., it has been used very abundantly (by people from all kinds of other studios and networks, etc.), and no known squabbles or legal issues have been raised over it.

Lee also added:

By the way, Ben is indeed working on “Indy 4″ and I
would be very surprised if there isn’t a Wilhelm in it.

An interesting aside - I’ve noticed a certain recording of a hawk cry appears almost pedantically in many desert and wilderness scenes in films, and it turns out it is in fact an often used recording - it’s mentioned in this Wikipedia page as “..a certain recording of the cry of the Red-tailed Hawk.”

A tradition of people who know the in-joke of the Wilhelm Scream is to shout “Wilhelm!” whenever they hear the sound effect in a movie. But if it isn’t cool to use the Wilhelm Scream anymore, how about something else?

This scream of Howard Dean, the “Dean Scream”, famously baffled and alienated the public to Howard Dean (arguably in part because the press replayed the “Scream” a lot - which.. I dunno.. it’s pretty funny and may deserve press).

I pulled that flash video out of YouTube, dumped its audio to a .wav file, made a sample of the audience cheering noise in the background of it, and then used that noise in a noise removal tool to isolate a very good approximation of Dean’s Scream without the audience cheering in the background.

(There are technical reasons this sound may not be “perfect”, but I doubt I’d hear much or any difference without those factors - also that’s an mp3 burn of the .wav file).

I wish, oh how I wish, that the “Dean Scream” was legally a for-sure “in the clear” sound to use in any entertainment project. For informational / educational / news use (such as this post), it’s in the clear under “Fair Use” - but it isn’t necessarily in the clear for use in entertainment media.

If another actor imitated the Dean Scream however, and released it to the Public Domain - hey, we could have us the basis of something new.

Wait a bit - I think I’ll do just that. :)

Re: CP80 Initiative

Awful Stuff, Good stuff, Hackles, Techie Stuff, philosophy, politics No Comments »

Derek Bambauer at the INFO/LAW blog concludes against the CP80 Initiative, which proposes a means of regulating internet pornography.  This is what I have to say of his post, in summary: he glibly dismisses the harm of pornography while discouraging an arguably Constitutional measure which could very well effectively regulate it, which measure in my opinion he very hastily (never mind erroneously) labels "Unconstitutional", while he does not even accurately reflect the measure's presentation, and responds to problems which the measure does not pose.  Further he does not either seek out or propose an effective alternative to what he believes would be ineffective.  He is of course not obligated to do that last (or to take the measure seriously, for that matter), but it would be more helpful than his misled, prolonged "No."

I would not write as extensively as I have here if Bambauer's arguments were not taken seriously, but they are.  At the moment two trackbacks to Bambaeur's blog (say that ten times fast!) - [here's one] - [here's another] express sympathy with them, and my own well-liked visitor Hydralisk previously seemed to express sympathy with the arguments.  A quick 'net search reveals others who would disagree with them - [here] - [here] - [here] - [here].  I'd like to note that several of these seem to link support of CP80 with a necessity of religious action (specifically, Mormon or Latter-Day-Saint religious action), and I'm uncomfortable with that.  The Mormon church does not tell its members which political or legislative measures (or parties) they should support, but advises members to support whatever they individually believe is best; which admits and expects the possibility of variance in legislative and political preferences - so Mormons should not presume or imply that we should support any political effort as a religious matter.  Unfortunately, doing so is an exceedingly common (and irritating) mistake that Mormons make.

Now, as contrasting with Bambauer's post and the apparent agreements with it, I very much think we need an entirely different vantage on CP80.

My arguments go into (very great) detail, but I'll start by summarizing some of the reasons I think CP80 could do wonderful things for the United States of America.

  1. It is an arguably Constitutional proposal which could effectively regulate internet pornography (where current regulations virtually do not exist).
  2. As a visitor to Bambaeur's blog pointed out, there is a longstanding and sizable amount of research indicating that pornography damages people; here only in summary I might suggest that legally and effectively upholding the possibility that pornography is detrimental to people's Pursuit of Happiness could only do so many good things, because in general, when people are given the option to have their Pursuit of Happiness protected (here, by being given a choice to have their right to avoid pornography enforced), they tend to choose the Happy path, and Happy people do wonderful things for our nation :) among those things being more productive and contributing to our nation's economic growth (or "General Welfare"), which leads to the next point.
  3. Pornography overwhelms the internet in terms of page usage (what people access on the internet), and very possibly overwhelms high technology commerce; while there are virtually no effective safeguards against it for people who do not wish to access it. If CP80 would effectively keep pornography out of the workplaces and homes of citizens who do not desire it - where otherwise that is something quite difficult to do (the most cautious people run across internet pornography accidentally) - and pornography is a very substantial economic hindrance where workers who are hooked on it can waste great amounts of work time and resources on it - by enforcing means of voluntarily removing a very sizable obstacle to economic growth, it could prove a very sizable economic boon.
  4. CP80 could much more effectively protect one of the rights of children in an area where that right is virtually unprotected; that right being to not be molested: for when a child is exposed to sexually illicit material it is a form of molestation.  On "virtually unprotected", effective safeguards are difficult for consumers to access, existing safeguards are paltry and easy to go around, and there is substantial data that very large numbers of youth and children are being exposed to pornography - in private and in public places.

According to the "about" page at his blog, Bambauer is an assistant professor of Law at Wayne State University Law School in Michigan (but I do not wish my first advertisment for his reasoning on this topic to imply that his reasoning is always so, nor that his school is so).  Two other lawyers also write at the blog, both of them respectively Assistant and Associate professors of Law elsewhere, and the blog is hosted at their former Law school, Harvard.

I've been working at this entry on-and-off since Hydralisk left a comment at my previous post on the CP80 initiative - quite a while ago, but as these are unresolved very democratic questions the debate remains very relevant. Last entry on the topic I didn't much say what the CP80 initiative proposes to do. The larger abstract concept is to break the Internet in the United States into two separate "Channels" - one channel where pornography is allowed, and another channel dubbed the "Community Channel" or "Community Port 80", hence "CP80", where such things are banned. I think this is a fantastic idea for the reasons I summarized above, and there may be other reasons you'll see throughout this post (in addition to the details of my reasons).  Before responding to Bambauer's post in detail I'll respond to Hydralisks' previous comment.
