So you want upload some video huh? Well before you do just some tips so you do not get frustrated in the process.
THUMBNAILS:
Thumbnails are autogenerated based on the first frame of the video. As of right now we cannot manually change it so if you want to present your videos in the best, add a JPG or PNG to the first frame of your video so it is picked up as a Thumbnail. If you use tools like Filmora I know there is an option to do this for you at generation.
FORMAT:
We highly suggest you use MP4 H.264 codec for your videos, WebM is nice also but MP4 is a little universal and will not give any issues.
That's it nothing major just a few key things you should keep in mind. Happy uploading.
