FCPX Has Bad Audio

[Bill Davis]

[Scott Houston] “My situation involved captures from an ATEM TV Studio that saved h.264 files with AAC audio (no other choices).”

Back in the day, there was a LOT of audio anomalies in the early BlackMagic ATEM systems.

I remember HUGE processing delays with the default multi-track audio embeds – even if they were empty.

I just did a gig at NAB using a current ATEM system and none of those original issues were evident.

My advice is to make absolutely sure all your software and firmware updates are totally current.

The BlackMagic stuff is largely video over IP – and like all computers, if the code isn’t current, there can be all sorts of bugs lingering that have been addressed over time.

Good luck.

Good advice for sure Bill, but in this case I am 99% sure it is a FCPX issue.

I say that because while testing I created another h.264 file directly from a camera (not captured by ATEM TVS switcher) and purposely set the audio format to ACC and got the exact same response with FCPX introducing the digital noise after importing the file. Everything was identical to the files captured by the ATEM Switcher as far as being able convert the audio, then import, etc… as described above.

So working down the rabbit hole trouble-shooting-wise, that leads me to believe it is some oddity with FCPX’s handling of the AAC stream when importing vs. some oddity with the way the file was captured.
