Clips out of sync.

Richard Eary · November 25th, 2009, 12:23 AM

I recently worked on a commercial only to find I had a lip sync problem. The problem was traced back to the file that HDLINK created. My fix was only to move the audio a few frames to align it with the video.

I was hoping this was a one time deal. It sound like others are having the same issue. The footage was captured on a Z1U and captured to the computer using iLink and HDLINK.

Has anyone found a work around?

Here are a few specs of the environment when the problem occured.

Premiere CS4 64-BIT
AJA LHE
Latest build HDLINK - iLink
1440x1080 60i (may of been upscaled to 1920x1080 60i)

If you don't file a trouble ticket you may not be heard. I have not be told of anyone submitting a sample file with this failure. If they arrived today, I was out the office. Please send in a sample -- I asked here on this thread for that 5 days ago.

David Newman: What do you mean a 'sample file', export a clip and upload it? How will that help you solve the issue? (just curious)

Any clip that plays out of sync in CS4 but it in sync elsewhere, we never seen that. Not happening here, so we need your clip(s).

The clips I can put my finger on that have the audio synch issue are all rather long- a little too much to send.
When I get back in town next week I will shoot a very short EX1 clip of hand claps, or somesuch where the synch is obvious. If the CFHD.avi exhibits the audio synch problem in CS4, I will submit a ticket and FTP the clip.

I'll find the avi file this weekend and file a trouble ticket. Maybe that will help. Again, I have only experienced this once.

ok i filed a support ticket, and submitted some files.
the culprit it seems is AE...in most cases
everything I render to cineform through AE has audio out of sync...be it RED,HVX ect ect

just did a little test again and sure enough the problem was there

I do a monthly greenscreen shot in which i pass through 15 minutes of footage a month...some of it Red....some of it HVX....
so in my mind every cineform shot i did had audio out of sync...which is not the case...only those passed through AE
