Well I finally had a successful session with AS. I just couldn't do anything with the AVI files that I had produced with Visual Reality and Renderize so I decided to try creating a series of JPG files instead of an AVI. I read the JPGs into AS and spliced and edited to my hearts content. I merged movies, I saved to AVI format, all without a hitch. You don't know how close I was to throwing this stuff back to my dealer… Any idea what could be causing the incompatability with the AVI files?

I haven't had a chance to try it again today but as I recall I saved the JPG series as an AVI file and then tried to manipulate it again. It looks like (at this point) the .JPG series is the only stable format for me. Also – when I saved it as an AVI it was HUGE! Over 70 MB! The collection of JPGs is only 7 or so. I'm a little dark on the whole vid compression deal. Which scheme should I use?

Which scheme should I use? << AVI being huge may be that the last described or default codec being used is the 24-bit completely lossless version. try the same AVI saved using cinepak and see if you get more reasonable sizes. the included hardcopy does explain a bit about codecs, as do the online help references. -dave

Here's what I don't understand: Renderize makes about a 7 MB AVI containing 300 320×240 frames. I did the same thing to a series of JPG files. I read the JPG series into AS and tried to save them as an AVI. I either got a 60 MB monster AVI (that Vid for Win ran great) or a <2 MB AVI that looked like crap. I tried a lot of the CODEC combinations and never did find one that approached the size and quality I got with Renderize. I didn't scientifically go one by one with all the options because that'll take forever. I know I tried the cinepak option altho' I don't remember which side of the scale it was on. When I get some time I'll try more and take notes this time.
