Yes. The maximum file size is 50 MB for individual GIF or MP4 files. Using a hidden GitHub feature called "GitHub Blocks," you can push that to 100 MB for each file. The GitHub repositories (your main branch) should remain less than 5 GB.
If you need to upload an image or video with a higher file size, use a GitHub program called GitHub Large File Storage (LFS), which has a maximum limit of 2 GB per file for Free/Pro users.
