I cannot change acquisition rate with Pinnacle Studio 10.6 Plus

[sballo]

In the options menu of Pinnacle Studio 10.6 Plus, in the capture options, even though I chose a personalized profile I still can't personalize some data - for example I can't change the acquisition bitrate - that values appear in grey color and can't be changed. I have a DC10 acquisition card, and with Pinnacle 9 I have no problems, I acquire analogic video up to 6000 kbyte/s - but with Pinnacle 10 the system wouldn't allow me anything else than 3600 kbyte/s, in the personalized profile. Somebody can figure out why?

Pinnacle is probably capturing DV AVI which has a fixed bitrate.

Not really. The problem in my case is more complex. DV acquisition has a fixed bitrate, but with my Studio 10 it's only 3000 kbytes/s, while with Studio 9 it's 3600 3000 kbytes/s. That's already strange. But my Pinnacle Studio 9 can also acquire analogic video with my old Pinnacle DC10+ card with a bitrate that I can set up to 6000 kbytes/s. With my Pinnacle Studio 10 I should be able to do the same (or better, i.e. higher bitrates), but it doesn't allow me. The acquisition bitrate is blocked ALSO for analogic acquisition, and the lock is at a bitrate of 3600 kbytes/s...

What codec are you using?

If this page is correct:

the DC10 is a Motion JPEG capture device. That would explain why you can set different bitrates for MJPEG capture. But if you are using Studio 10 to capture as DV, Studio is converting the MJPEG data from the DC10 to DV on-the-fly. That would explain why Studio presents a fixed 3.6 mb/s.

There are higher bitrate DV variations used in professional equipment. DVCPRO has a double bitrate variant that uses 4:2:2 instead of 4:1:1 color subsampling. I doubt Studio 10 supports this though.
