My proxy import has no audio after choosing "remove silent channels'.
I have a 90 minute live video that was shot on 3 good SONY cameras.
Some are contiguous and some are broken up into non-contiguous clips. I am trying to make a video via a multi clip where everything is synched via audio from each clip. Then I will, after having them all in synch, add an edited audio track from my audio DAW to replace all the audio for the final edit.
the three camera file types are:
MP4: 3840 × 2160. Linear PCM, HEVC
MXF files
MP4: 3840 × 2160. Linear PCM, HEVC
1st attempt
I choose importing of video clips (4K) and chose both optimized and proxy.
That led to video that wasn't proxy and when creating those clips into a multicam clip my iMac Pro (2017 choked trying to playback the video. I searched and found the proxy files but couldn't figure out how to replace the heavy cpu clips the import created (over many hours of importing and rendering).
I gave up on that. Wished there was a 'replace video with proxy files from...' option. I couldn't find one.
2nd attempt
I imported the clips to a new project and choose only to import at proxy.
I also chose the option to get rid of audio that were empty.
As I notice with the 1st attempt I was getting clips with 8 mono audio tracks
and couldn't hear the audio until I went into the audio info window of each clip and changed that setting from 8 mono to 4 stereo. Then I could hear the audio to audition a clip for in and out points to import into the time line.
So to hopefully eliminate that step of going from 8 mono to 4 stereo on every clip, I choose to "remove silent channels'.
The result :
Now I have proxy video with no audio at all???
Can someone explain to me how to set up my import window to get both Proxys that will work well in my 2017 iMac Pro?
