While we don't impose a maximum file size for video uploads, you must ensure that your posts are in line with the following Instagram guidelines:
The maximum video width for Instagram in 1080 pixels and the minimum is 600 pixels width.
Unfortunately, this means there is currently no support for Super HD or 4K video uploads on either Instagram or Hopper HQ. The maximum is 1080px for all video files.
There is no height restriction for videos on Instagram, they can be any size as long as they are within maximum portrait & landscape ratios - 4:5 and 1.91:1 respectively.
Format and Frame Rate
At Hopper HQ, we recommend uploading your videos in .mov, .mp4 or .m4v format. The maximum support frame rate is 30fps.
Instagram often update their video format guidelines, so our best advice would always be to export one video file in your chosen format and size and test this in Hopper HQ. If this posts ok via Hopper HQ, create the others in the same format.
