Slow playback when using AspectHD and Multi-Cam feature? at DVinfo.net

Craig Irving · April 12th, 2007, 02:36 PM

I've been editing with Premiere Pro's multi-cam feature quite a bit recently in native HDV. Last night was my first time trying with CineForm, but it was incredibly choppy and I had to go back to my M2T files and edit natively.

Is this a bug? I find it odd since on a single cam timeline CineForm runs MUCH smoother than native HDV, but when it comes to multi-cam it's the opposite. I was using the "High Quality - Large Size" CineForm intermediate codec setting. Perhaps my computer couldn't keep up with it? Will my success be any better with the "Medium Quality - Medium Size" or "Low Quality - Small Size" preset?

It still seems rather odd to me. I have 2 gigs of dual-channel ram on an Athlon 3800XP+ system. I'm thinking about adding more RAM if that will improve things but I still haven't quite figured out whether or not I need to buy dual-channel since I've already commited to my main modules being dual-channel.

We haven't accelerated multi-cam yet. It is on the list.

Oh that's great news! That makes me want to buy AspectHD anyway just knowing that you guys are aware of it and are looking into it.

I'm happy to hear it's not my PC (or my imagination).

Thanks for the quick response David!
