Looks like FFV1 and lossless settings of x264 and [m]jpeg2000 are all at least decent cross-platform preservation options - and mjpeg2000 supports virtually all color formats, natch.

Lately I've been saving raw files as rawvideo. It's at least 3x larger than any of these codecs we normally use but I have the hard drive space to play with until I do a final encode to x264. This means I need to set aside around 500GB-700GB for a laserdisc project until I'm finished with it. If I were messing with HD material or film scans I'd probably want to use some sort of compression though.
Otherwise, for sd material I'd say Huffyuv because it's been around forever and can be used with almost everything. I quit using lagarith because it doesn't decode properly in all versions of vlc and I don't need a lossless codec that supports yv12.

Lagarith is faster and compresses more than MagicYUV, but playing an HD encoded file with VLC or MPC is almost impossible because of stuttering, while with MagicYUV it works flawlessly... agree that HuffYUV is great, in particular for laserdisc capture!

How do I take VirtualDub VHS captures from MagicYUV to MPEG2 for making a DVD?

DVD?!? You are ancient, man!
 Really, haven't done a DVD in years, can't remember how to do it...

I have found that with a multi-core CPU, the best lossless codecs overall are Ut Video and MagicYUV. On my test system, MagicYUV decompresses even faster than Ut Video (>450 fps vs >300 fps) but the test file was slightly larger (0.5%). If you're keeping the lossless video for archiving you'd want the most-compressed version even with the performance drop, otherwise the performance gains are much greater than the small intermediate filesize increase.
I didn't test compression speed since my test was for realtime video capturing, and both are way faster than realtime.

Lately I used MagicYUV but noted that opening more than one file at the same time - for editing purposes - sometimes give me problems... so I decided to get back to Lagarith that, since the last time which gave me errors, it worked flawlessly... also, it compresses more than MagicYUV.

I've started using Magic more and more after a recommendation from Doombot but also keep Lagarith around. Sometimes its a matter of trying both and seeing which has better results.
