Playback of SD image sequence

Hello, everyone,

as I mentioned in an earlier post, I am currently trying out Vegas as my tool of choice for editing my animations. Naturally this involves dealing with image sequences with lossless compression (i.e. .png or .tga).

When I loaded such a sequence into the timeline (at SD resolution) the playback was not exactly smooth, playing at maybe 6 fps in the preview window ("best/full" selected). Is this normal? I have a Dual Athlon 2800 with 2GB RAM.
What - except original DV footage - will play back in realtime, preferably even on the external monitor?

Any input greatly appreciated.

Cheers,
Marc

That's probley normal. Try rendering to a new track.

I've done image sequences with 32-bit TGA's & haven't had any problems. Those were even from my "C" drive. :) Are you doing anything (like alphachannel) to them?

Not doing anything special with the image sequence. I'll try rendering to a new track, but can't see how an uncompressed .avi will work better. I'll give it a try when I'm back in my office. Also, maybe .tga work better than .png. I'll check and report.

could the resolution/aspect raio be off & Vegas is re-figuring that out on the fly? I've got an XP 1800 with 512mb RAM & sequences of TGA's don'y choke my system (at least not with nothing on them).

oddly enough - also depends how many are in a directory .. if you have more than 10,000 or so (not sure of exact figure) .. vegas will play them back slower .. i sometimes have 100,000 + in a directory and then windows goes to a slwo mode every tiem i try to access that directory (and i have all the right stuff turned off) .. it's a pain and i wish there was a cure ..

the fix for vegas though is pretty easy -- frame serve them in .. which is also good because you can then set frame rate before import, as well as any resize or crop...

and as mentioned -- make project properties match your import (progressive, frame rate , etc )
