I've received conflicting answers from Adobe support on whether CS6 supports MP4/AVC/h.264 files.
Premiere Pro has no problem with my AVCHD files but stutters heavily on the MP4 files, both of which are produced by my Canon XA20 camcorder.
My system is fairly robust:
CPU: Intel 3770K
Memory: 32GB with 26GB available to Premiere Pro
Source/Scratch disks: 2 x 256GB Samsung 840 Pro SSDs
GPU: nVidia GTX670 with CUDA enabled in Premiere Pro
This is the file's codec profile:
So, my question is: Is this type of file supported by CS6? If so, what may be the cause of the playback stuttering in the source and program monitors?
Thank you for your help.
I think we have seen issues regarding mp4 from a Canon camera before.
Stick to avchd.
Ann's right. You're the third or fourth person I've seen report issues with those files.
Premiere Pro CS6 does indeed support a wide range of MPEG files. That said, there have been some reports of performance issues with mp4 files from Canon AVCHD cameras, with CS6. There have been a number of improvements in Premiere Pro CC and the Canon .mp4 files I have tried, played back without issue. If possible, you should give CC a try. If you are still seeing this issue with CC, then could you please post a sample file to verify?
If you remain using CS6, the workaround is to work with AVCHD files from this camera.
