Help with uploading

So I just need help to understand what’s the best way to upload on here with out a video cause I know I can’t upload a video since it won’t allow it so what else could I do? I only take videos btw and I try to make gifs but they’re always shit quality so if anyone has any advice please let me know

Compress the video make it a smaller file and then try to upload it. If the size is too large u won’t be able to upload…so compress ur vids

Keep video under 1:50 mins and 100mbs (as in my case) then upload, works ok then
