Question

Video rendering error: -50 (Final Cut Pro error -50: fillAudioBuffer failed)

I'm am using Final Cut Pro version 10.3.4 on a MacOS Sierra 10.12.6. I imported footage from a sony camcorder HDR PJ540 into FCPas I have many times before and created a movie. Some of the clips were labeled as clip #1 and others were labeled MAHO with 4 numbers following. I used both in my movie. I turn sound off on all the clips. I tried to share this movie to youtube and it came back with this error; Video rendering error: -50 (Final Cut Pro error -50: fillAudioBuffer failed). How do I fix this this. I have made and shared hundreds of movies to youtube and this is the 1st time this has happened. help please

iMac, OS X El Capitan (10.11.5)

I fix it!!!

The problem was with the audio of the original video clip from the camera. Detaching the audio from the video, deleting it, then sharing from iMovie fixed the issue. The alternative (if the original audio was important) was to open the original video clip in QuickTime and export it at whatever resolution it needs to be. Then import that exported video clip (audio and all) into iMovie.

Hey y'all!

Ok then I tried to do the Quicktime "solution" but it just didn't work, dunno why... The way I solved the problem is that I exported the audio only, from Premiere Pro CC and reimported it into FCPX (10.3.4) -All my work was done in FCPX so I never EVER intended redoing the editing in PP-, bad thing is I had to redo ALL the previous work in the audio track but that was WAY LESS than editing the entire clip in another software; So cut here, there n' everywhere haha! But it worked perfectly for me.

Regards.

I have the same issue but have no way of fixing it.

I found if I don't do any editing and just export to a file. It is ok. But, with some clip trimming and editing, this issue occur.

Could Apple give some definite solutions?

Hi Marco,

I read it somewhere but cannot trace it back.

Anyway, click the "speaker" icon on the top right of iMovie window, and select "auto", meaning automatically improve loudness. It works for me. Give it a try.
