.MOV vs .MP4 – Image Quality vs. File Size
Posted in Blog
Up until this past weekend I had used .mp4’s primarily to showcase my videos on websites such as vimeo. However when I exported my video Timelapses of 2010 in .mp4 format, I noticed serious compression artifacts in some of the darker scenes. I decided to try a .mov with the same compression settings and was pleased at how much better the video looked. The only downside was that the .mov turned out to be 5x the file size, but after this test I feel like it’s worth the extra size and upload times to have a better quality video. Here’s some snapshots of the settings and image example below:

Differences in Compression - .MP4 vs .MOV
Difference in File Size - .MP4 vs .MOV
yeah well, but html5 still does not suport quicktime.
aah, what a world that would be 😉
oh well, figures! 🙂
That’s helpful… any particular reason why you’re keeping the key frames at 24?
Thanks.
That’s the frame rate that my project was edited in. If I edited in a 30fps sequence in Final Cut instead, I would export with 30FPS key frames, 60fps with 60 etc.
According to vimeo, it’s best to match your keyframes to your framerate: http://vimeo.com/help/compression
