Audio sync problem ProspectHD and 7D at DVinfo.net

Bill Engeler · November 2nd, 2009, 08:07 AM

Hi - I posted earlier about this problem, and filed a ticket with Cineform, but haven't heard anything, and I wanted to see if anybody else had a similar problem.

When I convert MOV files shot at 25P with an EOS 7D to cineform, the HDLink log reports "Pitch-Correcting Canon 5D audio to 29.97." The audio then drifts out of sync about 2 frames per minute.

There are no settings I can find that mention 29.97, either in the camera or in HDLink. I'm in PAL land.
When I capture from my XHA1, there is no problem. It's only the 7D files that have it, after conversion.

XP, ProspectHD latest version

Any ideas?

This why Canon is remiss in not send us a camera. Seems like a bug. Could you please upload a short clip with obvious audio sync to ftp://ftp.cineform.com/pub/incoming (use regular windows explorer then drag in the sample file.)

Sorry for the delays in support, the support lead got married this weekend.

Congrats to the newlyweds. I sent a file to Cineform before via yousendit. I just updated the ticket with the link information. I did it this way rather than upload the huge file again, but I could FTP it to you if I have to. Thanks.
