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

July 9th, 2008

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”.
