AE7 + HDV = Nightmare
i’m trying to figure out if there’s something wrong with my system. When working in an HDV 720 composition environment, everything’s painfully slow. i’ve tried both .m2t and wmvhd files. .m2t files were captured from vegas 6D.
with absolutey no effects, the HD video @ 1/4 resolution ram previews @ 0.5fps. scrubbing is absolutely impossible.
i have after effects 6.5 installed as well, as i wasn’t sure if i wanted to uppgrade just yet. i’ve heard about peformance increases in 7 over 6.5…but in reality, 6.5 is a little faster in previewing HDV. AE7’s is slow to the point where working with these formats is impossible! vegas can do realtime preview of HDV @ 1/4 res. i just don’t get it.

You’re supposed to convert the HDV files to an intermediate codec. HDV has interframe compression, basically MPEG-2, and AE doesn’t like that sort of thing.
Editing apps are now designed to deal with interframe compression for video editing purposes. AE isn’t an editor, so it needs full frames, as in Photo-JPEG, Animation, DV, etc.

Correct me if I’m wrong (haven’t had the pleasure of working with HDV yet)… But wouldn’t this be an ideal situation in which to use proxies?

Well, as long as the proxy has all frames, and isn’t interframe-compressed, as HDV is … sure.
But I don’t use proxies very much, except for ridiculously big stills. Not for HD. But that’s me. 🙂
