Question: how long can you send a video on messenger?
Answer: You can upload videos with unlimited bitrates, up to 1 Gigabyte in size. The max file size and time length, though, are 1.75 GB and 45 minutes. But if you go beyond a 1 gig file size, then you must limit a 1080 HD upload file to a max bitrate of 8 Mbps, and a 720 HD file must be limited to a max bitrate of 4 Mbps.
