I just tried to upload this 6.6MB file and got this error message:
“Sorry, that file is too big (maximum size is 8072kb). Why not upload your large file to a cloud sharing service, then share the link?”
This software that runs this site probably might encode your movie into Base64 or some other bloated encoding during transfer (Discoure).
I found animated GIFs to work better on this site, because they are displayed inline. I use a software called Claquette to capture screen videos and export animated GIF files (using 50%) original size.
OK, Great. I tried in in another thread. In order to get the size small enough, I had to make the size a bit smaller and quality at 80%… (50% Size and 100% Quality is still >5MB) But, you should be able to get the idea…
If you are using Claquette, there is a built-in crop feature which you can use the cut out irrelevant parts of the screen, thus reducing the file size.
