“What format should I upload my videos in to get the best quality from YouTube and other sites?”
I get this question ALL THE TIME.
Follow these guidelines and you should have great results.
1. YouTube (newest) recommended settings are:
- MPEG4
- 640 x 480 resolution
- 64k Mono or 128k Stereo MP3 audio
- 30 frames per second
2. I upload the videos in these formats (listed in order of preference from high to low):
- MPEG4
- QuickTime
- AVI
- WMV
- DivX
- MPEG2
- RealMedia
- Flash
4. Keep an aspect ratio of 4:3 (640 x 480, 480 x 360, 800 x 600, etc.), otherwise the quality of your video will be degraded.
5. YouTube now has a Hi-Res Mode. This means YouTube creates 2 new copies of your video to suit high and low speed connections:
- 448 x 336 pixels, Flash 7 video @ 900Kbps. Audio @ 44.1KHz Mono.
- 480 x 360 pixels, H.264 video @ 512Kbps. Audio @ 44.1KHz Stereo.
Most of the other sites follow a similar formula.
Just remember YouTube limits the length of a video to 10 minutes. That’s a good rule of thumb anyway – keep them shorter than that!
Sites such as Viddler supports long videos and large uploads. I get EXCELLENT results from Viddler if I want to embed a video from that program on a page.
