Using intermediate files for HDV editing
I’m just starting to figure out how to use intermediate files when working with HDV footage. Even though I’m using 7.0d, editing HDV, especially on my laptop, is annoyingly slow.
So I read this in the Vegas help file: “If your intermediate files were rendered using the CineForm HD codec, you don’t need to replace the intermediate files with the transport streams.”
Does this mean that if I render an SD AVI file, click “Custom”, and then hit the Video tab and choose the video format “CineForm HD Codec 2.5”, that I’ll render an intermediate SD file that won’t require replacement when I’m ready to render in HDV?
Before you answer – I tried, and it doesn’t work. I can render such a file, and when I stick it in the timeline, I can tell that Vegas knows it is a different kind of file, as it shows the filename on the timeline, regardless of whether “Active Take Information” is enabled under the View menu. But the aspect ratio of this intermediate AVI file is wrong (squished left right), and when I render to an HDV file, the result looks equally squished, and is definitely not in HDV. It renders exactly as it looks in the preview window.
Am I doing something wrong, or is what I’m trying impossible to begin with? I do know how to create intermediate files, edit them, and replace them manually (the hard way). I’d just like to know if using the CineForm HD Codec 2.5 can somehow result in a situation where replacing the intermediate files would be unnecessary.
Thanks

It means that the Cineform files are good enough to create your project without swapping to the original HDV files before final output.
However, Vegas 7 makes intermediate files unnesesary as it handles m2t files just fine. You need to figure out what the bottleneck is on your machine.

Gary, should I notice no difference between editing SD AVI files and HDV M2t files with Vegas 7d?
Neither computer is top of the line, and I’m sure both could use upgrading. The laptop is a 1.8 AMD with 768MB of RAM and 128MB video card, and the desktop is a P4 2.8HT with 1 gig of RAM and a 128 MB video card. Should either of these be able to handle HDV without being slow? Both handle SD projects, even long ones, without any issues whatsoever. On the other hand, both are somewhat jerky when dealing with HDV files on the timeline. Hence my interest in intermediates (at least until I can buy more RAM).
Thanks again.
