Optimize MXF Peak File Generation

Optimize MXF peak file generation to look at only the audio portion of the file. 

This is a bug / feature request. 

 

Steps 

 

1. Import MXF wrapped video file (ideally something big like 4444 prores or XAVC-I 4K)

2. Audio peak file generation occurs 

3. Notice that the peak file generation is pretty slow compared to how long an audio only track should be

4. disk activity kept very high while Premiere Reads entire file, video, and audio to make an audio waveform. 

 

Result: MXF Waveform generation takes a really, really long time on high resolution media, when Premiere should be loking at the audio of the MXF file.

 

Expected Result: When footage of similar file size and resolution is in a quicktime wrapper, peak file generation happens at a 3-4x pace. 

 

Request:

Optimize MXF peak file generation. 

 

If for some reason you have to delete your entire media cache, which happens often with troubleshooting performance, Premeire can take an entire day to read audio data from 6TB of media off of  spinning disks and raids. It doesn't need to be this way.
