Deecey - I totally agree with you. I render all my animations as "full frames uncompressed" or as .bmp still frames, then do all my effect and transition work on those formats until I am satisfied, and then I render to .mpeg2 from my video editor. My last 5 minute animation takes 40 gig in it's WIP format, lol, so space is definitely a problem. Shadownet - you shouldn't render still frames as .jpg's. You lose some quality when converting from jpg to your video codec. (unless you set your jpg compression to nothing)
