Audio out of sync when using proxy media

Hello.

After I edited my original clips (used blade and trim) I wanted to add more clips on the second timeline. For a better experience, I created proxy media for all clips (H.264). After that, I see audio desynchronization. All dividers on clips (that I made with blade) have moved.

After I deleted proxy media -- sync gets normal. How should I create proxies?

Thank you

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? 2.5 Ghz 14-core Xeon W Radeon Pro Vega 64 - 16 GB 128 GB 2666 MHz DDR4 Ventura 13.7.5 I have Final Cut Pro 10.8.1 thx, LG

FCP sharing: 120fps clips in slow motion I have a FCP Project where all the clips are at 120fps. It plays perfectly in FCP on my Macbook Pro, but when I share it some of the clips are in slow motion. How do I resolve this? If I change the Project’s frame rate to 60fps it plays properly, but I really want 120fps.

Syncing issue I'm having bad luck syncing a separate audio file to my video. Sources: Gopro footage from a Hero 11 at 48khz and 23.98fps Zoom M4 audio recorder at 32 bit, 96khz. I've actually used this combination a couple of times now with no issues at all but this time there's a huge drift. Even when I sync at the beginning and then speed one of the two up to sync at the end as well it will be out of sync in the middle. I know it's not ideal to work with different sample rates of sound but had no issues with it till now. I've tried working on both a 48khz timeline and 96khz timeline (both 23.98fps) Any suggestions how I can make them sync? (MacBook Pro M2)

The fractional frame rate of the project can create problems. Is there a reason you set that frame rate rather than the media frame rate?

Try this. Copy everything in the existing project and make a new project that's 4K 3840x2160 at 30fps. Paste the contents of the old project into the new project.

Can you give complete details of the original media from the QuickTime Player Information window? Not Finder information.

Not really, I didn't change anything in settings or during the creation of the project
