If it autodownloads it probably a problem with the server response headers or the file uploaded. Catbox does no postprocessing of video files, and Chrome needs an exact file type before it can play videos iirc. So the fact that you need to autodownload probably has to do with the specific file probably (e.g: moov atom in wrong place, unsupported file type, etc...) Streamable actually postprocesses the videos with ffmpeg so any browser can see them.

Rumor has it Streamable will be cutting down on the free uploads anyway since theyve been bought out by Hopin (a zoom alternative)

A good Streamable like alternative is apperently videy.co

wat I'm pointing out how multiple times in the last few days a streamable link (((disappeared))),.
