I'm finding AMA'd GH4 4K footage (3840x2160p23.98) very troublesome to transcode in a Mac MC 7.0.4. Are other people having more success with this?
The actual video files are H.264 quicktimes (@ 100 Mbps, I believe), so AMA can link them fine, although they seem to put a huge demand on memory.
When I try to transcode these files to Dnx36, the process typically fails quickly, typical error:
"Exception: AMAProducerTask::Execute: AMA Plug-in Unable to Provide Sample"
I have a bin with say 24 clips for a total of about 9 minutes of footage. When transcoding an assembled sequence, it gets through one 35 second clip before the error comes up. If I select multiple clips in the bin (3 clips say), and try to transcode, it will again error out after transcoding at most 1 clip.
Transcode settings have compatibility 'on' to bake in the HD framesize, colour transformations unchecked to leave them live (although these clips have no LUTs applied in any case.)
If you are able to transcode clips like this successfully, I'd be curious what software version and machine you're using. If you're using a different application to transcode this type of footage, again, would be curious about your workflow.
Thanks,
--Michael
