Ok Ill give it a go... for now
Yes it does, Ive only used it a few times ( with Vegas 6.0d) but it uses an intermediary codec to produce a DV like file still keeping HD resolution. this takes time and uses up space but makes HDV easier to edit on more modestly specced PCs. Ive only tried Vegas 7 trial and Im not competent to comment on its HDV performance. There is also the option of using a DV proxy
Have a read Sony HDV Camcorder (editing software)? Help? |
Senu you've got it right. The Cineform codec is indeed "DV like" in that it is intra-frame compression only (not a group of frames like MPEG). There are 3 main benefits of such a codec:
1. Easier on the PC to edit
2. Retains its quality over multiple generations of renders
3. More accurate colour correction
Point 1 can be an issue with "modest" PCs. You want to be able to preview your edits in full rate, and many PCs can't keep up. Though with Vegas 7 the performance of editing native HDV is very good. I edit with a 1.6 Mhz Pentium M laptop. With Vegas 6 I generally used either Cineform or a proxy, as otherwise it was too slow. With Vegas 7 I edit the native m2t, and it fine.
Point 2 only comes into play if you are doing complex edits where you want to do multiple generations. E.g. you want to render out a section, then use that rendered file in another production. With Cineform you can do 10+ generations of renders and not see a difference. With native m2t, you would notice a quality loss after multiple generations. If you are doing just a single generation - e.g. capture, edit, render out - then there is no quality advantage to Cineform.
3. I'm not an expert on this, but if you want to correct the colours in edit, as Cineform has less compressed colour space info, it is more accurate.
