Hi there,
What kind of video compression works best for saving, uploading, downloading, etc. videos? Just wondering. Thanks for any help though.

Mpeg, Xvid, or Divx would work just fine. I personally use <a href="http://www.tmpgenc.net/e_main.html>TMPGEnc</a> and compress to mpeg. It's more universal, you generally don't have to worry about if people installed the right codecs.

Saving/Archive: You want a high quality codec. If you have the space HuffYUV is the best. But a high quality MPEG2 file will do nicely as well.

Internet Distro: Low-birate lossy compression w/ MP3/OGG audio. MPEG1 is the most universal format out there. But higher quality can be obtained with XviD/DivX in a AVI container.

I thought editing MPEG wasnt frame accurate...or do you mean simply saving for only watching aftewards?

MPEG-1 isn't frame accurate when seeking without it indexed. MPEG-2 is frame accurate IIRC with or without the index file.

Depends on the software. In Cinelerra, they're both frame-accurate with index files, and cause the software to crash horribly without.

Technically all video compression techniques need to be frame-accurate unless it's some whacky custom solution, like where the frame-rate is variable(even those can be made frame-accurate tho).

It's all in the codec and the way they are decoded. Also this is for Saving/Archiving, I didn't tell you to edit your video like that. This is a final render of your project, not the actual clips you'll be using.

For web distryo: XviD/DivX/ MPEG1 all work fine, but only for web distro.

How does high-res (640x480), low-bitrate (1mbps) MPEG-2 stand up to MPEG-1 for internet distribution purposes?

Mpeg2?

From a 'viewer-only' point of view those are much worse than xvid. Half the encodes people distribute and call 'mpg2' files won't even play in BSPlayer (an mpg2 only player). They crash the entire computer when loaded on regular amv players. Either they aren't encoded properly and *that* is why they only play on Winamp 1.87, or it's a bad format for universal distribution.

It's better quality-wise...probably not by a LARGE margin, but it should be noticable at least...
But some people would have difficulty playing it.
