Q: Audio Cut Short with FCPX

Hello Everyone,

 

Yesterday I came across a problem for the first time. When I imported a video/audio file (gameplay) the audio is cut off at the end of the clip. I was able to play the complete with the full audio in VNC, and I was able to import the clip to my pc using Sony Vegas without this issue.

I test importing a audio only file, and that worked just fine. It seems to be only with a video/audio file.

Does anyone have an idea why this is suddenly happening? I have restarted my macbook (2015 late spring) and uninstalled and reinstalled FCP. I am running the latest version as well.

Thanks in advance! audio problem.jpg

    If the audio is not an .aiff@48kHz file, try transcoding it and give it another shot.

    Hello,

     

    Thanks for responding and helping out, really appreciate it. So I think I did what you suggested. I imported the video/audio clip, detached the audio and deleted it. Then took the file and imported to audacity. There the audio file played in full. I made sure it was at 48k, and saved the file as an AIFF-C audio. Then exported the file, and moved it onto FCX.

    Again the same problem reared its ugly head though, as the end of the audio file was muted again for some reason. Only this time I can actually see the audio waves, but nothing plays.

    Thanks again for any help anyone can provide. audio not working.jpg

    I'm not understanding why the last bit is being muted.

    Does the muting match the previous file?

     

    Try regular .aiff without the compression is my only suggestion.

    I am having a very similar problem myself.  This started about a week ago.  The clips I import are H.264 MP4 clips.  Each clip has 3 stereo audio tracks.  They used to import just fine, but last week it started cutting the second and third audio tracks in half.  So the first half has audio, and the second half doesn't.  You can see in this screenshot here.  I'm at a loss as to the cause of this problem.  Any help would be appreciated!

    Can you tell us how the clips arrive into FCP X and are they camera footage?

    They are screen recordings using OBS.  Channel 1 is all audio, channel 2 is my microphone, and channel 3 is the desktop audio.  I do it that way so I can better mix it in post, but with it doing this that's not possible.

    Hello everyone,

     

    I resolved my issue, but I endied deducting that the issue was with the final itself. I used a different problem (shadowplay) to record my gameplay, imported it back to FCP and everything worked just fine.

    The old filie I was using had a lot of issues depending on the program I used. Adobe premier on my MacBook the audio wasn't muted, but was off synced by 10 seconds. Moved the file to my PC, used Adobe, and the end of the file was muted. But, in Sony Vegas on my PC the the audio and video was synced and worked fine.

    So I drew the conclusion that the file for some reason was the cause of the problem, at least in my case. Hope that helps others somehow.
