I've had the same idea and have been experimenting a bit. Up to now I've used cinepak or indeo 4.5 (can't get ver. 5.1 to work well).
MJPEG is extemely fast in compression (about 10 to 20 times faster than cinepak or indeo) and for now it works well on my PC with resolume.
I still need to do some testing but it looks like it will be a good solution.
BTW both quality and compression (in relation to cinepak or indeo) is good with quality set to 15 on a scale of 20 (20 being maximum).
I just converted a 24bit 640x480 25fps clip which was 30MB in cinepak to MJPEG and got decent results setting quality to 11 (12MB file) but settled with quality at 15 (20MB file).

that sounds interesting,I'm not very happy with cinepac resolution,having to set the vidprojector slightly out of focus to coverup the pixelation ,but what means BTW and set to 15 on scale of 20???
Thanx

Hi julian,
BTW = By the way
Open the settings for compression in your favourite video editing program (virtualdub, pemiere, vegasvideo or whatever) and choose picvideo mjpeg codec from the list of codecs installed. There should be a button that says something like "configure". By clicking that button you acces a window with the settings for the Mjpeg codec. In the lower part of the window there is a bar with a slider. that determines the "quality" of each jpeg picture (which means each frame). The lowest value for the slider is 1, the highest is 20.
I've tried setting quality to 11 and got _decent_ results but I've chosen to compress my stuff with quality set to 15. This makes files a little bigger than 11 but gives me good enough footage for mixing.
You should try different settings and find out what suits you the most.
Bye

Lvis, are you saying you can mix 640x480 clips with this codec?
I can only get smooth playback at 320x240 with indeo etc even on a pretty fast machine.

I regularly mix 640x480 clips both in mjpeg, cinepak and indeo and they go smooth enogh even with a few effects on.
This happens on my desktop PC configured as follows:
P4 1.7 GHz, 640 MB PC 133 RAM, 7200rpm 20 GB HD, Hercules All in Wonder 8500DV, WinXP Pro

I believe winXP does not support the latest (5.1) version of indeo - there is a separate winXP version of indeo, but it isn't free.
I don't think indeo is being developed further. (pity)
