Fix MP4 Videos Not Embedding Properly On Discord

Have you been trying to upload MP4 or MKV videos on Discord but they are not embedding properly?

Or your videos won’t pop up when you upload them on Discord.

Not all mp4 videos are compatible with Discord, for an mp4 video to properly embed on Discord it has to be in AVC codec.

If you try to embed other codecs like HEVC (High-Efficiency Video Coding) or H.265 encoding, be prepared to run into some errors when trying to play them.

Codec in video language terms means a compression software that can process your video file so that it can be stored and played back.

In most cases for an mp4 (the universal video format) that has an encoding of H.265 to be able to play properly on Discord, you will have to convert the video to an AVC (Advanced Video Coding) also known as H.264 or MPEG-4 codecs with special software.

For video files in the MKV (Matroska) format, you have to first convert to the acceptable MP4 codec before uploading to Discord.

In this guide, you will learn why some MP4 videos are not embedding properly or playing in pop-ups on Discord and the solution to it.
