    Video-sound sync problem

    Hjalmar Molin Level 1

      I have the problem that the Canon EOS 5D Mark II does not sync video and audio from the start. The sound comes before the event. I have to adjust the audio channel by moving it forward when I edit in Premiere Pro CS5. Is it a bug in the software for the camera? I have firmware version 2.0.7. The result is the same whether I use the built-in microphone or a wireless connection. Maybe not a problem with Premiere. Have more than I have had this problem?

          What are the video settings, and what is your project preset?

           

          Have you tried dragging and dropping a file on the new item icon in CS5?

            Obviously, addressing the OOS issue at the start is the best course of action. However, if one needs to make the sync adjustment during post, this ARTICLE might prove useful.

             

            Now, there have been many posts on the Canon 5D/7D footage, but I do not recall any regarding OOS. Maybe I just missed those?

             

            I would look first to the Project Preset, and hope that with the proper Preset, matching the source footage 100%, the OOS issues will disappear.

             

            Most OOS seems to come from muxed MPEG material, or WMV material, and then with some H.264 material, but usually with Export.

             

            Good luck, and please keep the reports coming,

                OK, one quick question: I see that the Audio source is "Compressed." Is this AIFF?

                 

                What happens if you convert that source Audio to PCM/WAV (Uncompressed) with the same specs.? Notice PCM and not Linear WAV. First, I would do a Render/Replace of the Audio stream, to see if that changes things. If not, then I'd rip the Audio in a program like Audition, do a Save_As PCM/WAV and Import that into the Project, to replace the original Audio stream.

                 

                PrPro (and Audition) seems to have issues with AIFF (and MP3), so I am just guessing here.

                 

                Good luck,

                  I chose codec AAC,  but there is also the option AAC+1 or AAC+2. What is that? I also chose Frequensy 48 Khz.
