We often see people trying to edit MKV files in After Effcts. While some guys struggle mightily. What’s the deal? Why can’t we import MKV to After Effects and edit happily away? Read on to find it out.
Based our experience and as some guys mentioned in Adobe forum, .MKV is just a container, like AVI. There are, literally, zillions of different codecs that it could be. You probably just don’t have the codec on your machine with which that particular .MKV file is encoded. A quick fix is to convert MKV to After Effects compatible file type like MPEG-2, which will save us both time and trouble, then all we need is to drag the result videos for prompt editing.
Download and use Brorsoft Video Converter, which is able to resolve your trouble effortlessly. This video app can help you convert MKV into a different format (e.g. .mpg, .wmv) with least quality loss. You should then be able to import the new file into After Effects with smooth editing without any trouble. With it, you can also effortlessly transcode MKV to MPG for Adobe Premiere/Sony Vegas, DNxHD for Avid MC, WMV for Windows Movie Maker, etc. If you’re using a Mac, simply get the equivalent Brorsoft Video Converter for Mac to encode MKV to After Effects on Mac OS X(macOS Sierra, El Capitan, Yosemite).
