  • Screen recording of an interview not playing well in FCPX.

    I’ve used Movavi Screen Capture to record a Zoom interview on my MacBook Pro (late2016 running 10.14.6).

    The app first creates an .mkv file (which will play back using VLC etc. but isn’t importable to FCPX 10.4.10). It also has the option to save the recording as an .mp4.

    My first attempt at this produced a file which played back fine in VLC, imported ok to FCPX, but had no audio level.

    So, I used Permute on the original .mkv file to create a new .mp4. This imported OK into FCPX and the audio was all there. Hurrah. However, playing it back (in browser or timeline), it starts OK, but after a few seconds the video image slows down and stalls.

    I presume FCPX is having to do a lot of hidden codec converting work to play this file back OK.

    With everyone doing their interviews on Zoom atm I find it hard to believe noone’s come across this issue and found a workaround, but I’ve been searching, and apart from some references to the first missing audio issue, I haven’t seen anyone complaining of same problem I have re slow playback.

    Any suggestions of how to convert the .mkv into a file that FCPX breezes to? – my laptop’s not stupidly slow and 2.9GHz i7 and usually all my files play ball.

    Try Handbrake software.

    Thanks. Nice simple software. I realised the problem was probably frame rate as original was 30fps and I’m working FCPX in PAL 25fps. So using Handbrake I did a quick conversion to .mp4 at 25fps – quality seems good, sound is there, and FCPX is playing nice.

    I love this forum!!

    It may be that more people are not reporting this issue because they use Zoom’s own recording feature. (This may require a paid Zoom Pro account at 15USD/month.)

    In my experience Zoom records MP4 at 25fps with audio at 32kHz. I have edited many Zoom recordings in FCPX without a problem, though I’ve found that for some meeting participants Zoom does not do a good job of synchronizing video and audio.

    Sync is usually perfect, but I have found it sometimes to be as much as 6-8 frames out of sync. In these cases I separate the audio and video tracks in my timeline and move the audio to be in sync with the video. If I am hosting and recording the meeting, before the interview I have each participant (one-by-one) do a hand clap to simplify synchronizing in FCPX.
