[How to] Fix “After Effects MOV File Damaged Unsupported” Issue

Author by Oswald

Updated on March 19, 2020

Some Adobe After Effects users might have trouble editing MOV videos, since After Effects won’t open some of your .mov videos, instead it will pop up a dialog saying “After effects error, this MOV file is damaged or unsupported”. Luckily, I have found out two possible solutions to the issue and they work fine by me. Read on for more info and hope my solutions provided can be of help.

Here you can free download the recommended After Effects video converter to get started:

Solution 1. Provide QuickTime MOV Support to After Effects

1. If you’ve already checked that your videos are not damaged, the most likely root cause, of After Effects error can't import file, is that your video codec is not supported by Adobe After Effects. The picture indicates the videos supported by After Effects. As you can see, MOV is included but it says “requires QuickTime”, the implementation of MOV support (the capability of coding/decoding MOV) of Adobe Effects is actually based on QuickTime. Also, it requires the installation of QuickTime and the good communication between After Effects and QuickTime. Official link for QuickTime Installation:

2. Already Installed QuickTime?

In that case, you After Effects MOV file damaged unsupported issue could be boiled down to:

1) The blocked communication between After Effects and QuickTime

Fix: Remove/disable third-party firewall programs from the control panel, and try importing MOV into AE again and see if it works.

2) MOV support is interfered by some QuickTime component

Fix: Remove all third party components that you have installed to QuickTime, and add the necessary ones back one by one, until there’s one that causes your AE can’t read MOV files.

3) You haven’t updated QuickTime for a long time

Fix: Upgrade QuickTime Codec at:

Or download and install one of the best third-party codec pack at:

Solution 2. Convert Unsupported Videos to After Effects File Type

You should know that the MOV support via QuickTime has been removed in CC 2018. Thus adopting a proper video converter program to convert the unsupported video to be AE friendly is a better move. Besides, not only it is much easier and it’s also an overall solution – Converting your videos from rare codecs to industrial standard will free you from incompatibility issues for good. Now, I’d like to show you how to do so using the best video converter for Adobe After Effects: WondeFox HD Video Converter Factory Pro.
