Question

real issue importing movies (mac os)

Hi, its been a long while since ive used after effects on my mac, but im having real issue with importing movies into after effects. I understand that support for .movs has been removed recently, meaning that a lot of old files that once worked no longer do, but along with this im getting some strange results that are a little inconsistant.   For example...

I took a couple of movie screen grabs using the movie screen grab feature in Mojave. One imports fine - but the other does not.  I just keep getting a 'could not open source file' Please check file exists with correct permissions (86::1)   and then 'this Moov file is damaged or unsupported.

This keeps happening no matter how many times i take the screen capture!

could anybody suggest anything that may be causing this?

many thanks

Nick

    The problems depend entirely on the format. MOV has hundreds of variations. I work on a Mac with all kinds of .mov files every day.

    Check the info for your footage using Quicktime and let us know what you find. H.264 movies in a QT container can be incredibly problematic if they were compressed using the Quicktime engine. Apple never really supported that and has completely dropped support for compressing h.264 using Quicktime.

    Hi, they’re basically videos I captured using the built in capture fleather in Mojave (which is why I would have hoped they’d work. The default is h.264 - encoding software macOSx..

    the strange thing is that i took 2 screen captures. The first one imported fine, but now no matter how many times I recapture it refuses to import!  So frustrating :-/. Can’t believe apple have dropped the ball So heavily when it comes to video.

    Any ideas what may be going on?

    A couple thoughts:

    1. Dig through the settings of your capture output and do some trial & error to see if you can find a method that consistently works. If it's using variable frame rate, that would definitely be a potential culprit.

    2. Download Handbrake (free) and use that to convert your existing capture to something that works.
