Instagram video file formats: What you need to know

Choosing the right file format is an important part of ensuring your Instagram videos look good and play well on all devices. Here is a summary of the formats most commonly used for Instagram:

  • MP4 (H.264 Codec): MP4 is the most common format for Instagram because it offers the best trade-off between size and quality. This format is very compatible with Instagram's platform and does a great job of compressing a video without sacrificing too much resolution or size.
  • MOV: MOV files are another format shown to work with Instagram. MOV files are often used for higher-quality videos. If you are a professional content creator, you would want to use MOV files, because your quality is critical, and not a single bit of visual/audio representation should be lost in exports.
  • GIF: GIFs are perfect for short, looping video memes. The formats limit the resolution and length. It is best used for content that does not need audio, like Instagram stories or posts.

What video file does Instagram support

  1. Why can't I upload my MP4 video to Instagram?

If you are unable to upload your MP4 video to Instagram, this may be due to the video file being too large, the resolution not meeting Instagram standards, or you are using an unsupported codec. Instagram supports MP4 video files using the H.264 codec, but Instagram imposes limits on video file size and resolution. You need to ensure that your video is less than 4GB in file size and has a resolution appropriate for Instagram standards.
