Why is After Effects unable to play MP4 files?

After Effects is unable to play MP4 files because it requires the appropriate codec for decoding the video file. MP4 is a container format that can contain various audio and video codecs. However, After Effects only supports a limited range of codecs, such as Animation, ProRes, H.264, and more.

If you try to import an MP4 file into After Effects and encounter issues with playback, it is likely due to the codec used in the MP4 file. To resolve this issue, you can transcode the MP4 file using a compatible codec before importing it into After Effects.

One common approach is to convert the MP4 file into a format like QuickTime MOV or Animation codec, which are supported by After Effects. There are several video conversion software available, both free and paid, that can help you accomplish this. Some popular options include Adobe Media Encoder, HandBrake, and FFmpeg.

By converting the MP4 file to a compatible format, you ensure that After Effects can properly decode and play the video file without any issues. Remember to always check the system requirements and recommended codecs for After Effects to avoid any compatibility problems.

In summary, After Effects is unable to play MP4 files due to incompatible codecs. Transcoding the MP4 file using a supported codec will resolve this issue and enable smooth playback in After Effects.
