Vegas 6 Performance with Z1 footage
Anyone have any feedback on Vegas 6’s performance with 1080i footage in Cineform’s intermediate and Gearshifts Sony YUV codec. Own a P4 3.4, so I was curious as to how many layers with dissolves and moderate color correcting can be done in real time.
Is there a huge performance difference between the two codecs?

To my knowledge, gearshift only automates what you can already do in Vegas. The Sony YUV codec is part of the Vegas install, although it is only available inside of Vegas iteself.
Sony YUV codec will not play nearly as smoothly as Cineform intermediate on your average computer. The bottleneck is the drive speed. You must have a very, very, very fast array in order to get full frame rate playback of the uncompressed YUV files. You need 122 Megs per second for HD uncompressed. Plus you need a LOT of storage space. 1 min of HD 1920x1080i YUV uncompressed = 7.3 Gigs which is 438 Gigs per hour.
Intermediate is much more efficient editing at around 9 megs per second. 1 min of HD 1440x1080i Cineform intermediate = 560 Megs which is 33.6 Gigs per hour. Your performance for the Cineform intermediate files should very closely resemble DV performance. This is why using the intermediate makes it possible to edit HDV on a laptop with Vegas.
So — be prepared to spend a LOT of time rendering if you are editing HDV. And remember that batch capture and recapture is not yet possible. The results are stunning, but make sure you budget the time necessary to convert to intermediate, and then the time to convert back to HDV for print to tape (if you are going back to HDV tape).

Thanks so much for the response Tim. I was unaware that the Sony codec was uncompressed. I was just wary of Vegas’ performance with the Cineform codec compared to Adobe Premiere. Just wondering if Vegas 6 added a little better performance than version 5. Good to hear of it’s dv like performance. I think the Adobe solution shines with Cineform’s real time effects, which they don’t have with Vegas.

For Vegas 6 CineForm worked with Sony to get even more performance out Sony’s video processing engine. Although the solution is quite different to the Adobe Premiere implementation, both offer real-time performance.

David — great job!
I’ve enjoyed the looks on everyone’s faces when I’ve shown how well the Cineform HDV plays back.td
