The Silent Failure Nobody Warns You About
You take a nice short clip on your iPhone. You open Telegram, go to Settings, tap your avatar, choose "Set Video". The upload spins. Then... nothing. No error, no toast, just the old picture staring back at you.
I hit this three times before I realized what was happening. iPhone records video in HEVC (H.265) inside a .mov container. Telegram's video avatar accepts H.264 in MP4. So the app quietly drops your upload on the floor.
That was the seed for @liveavabot. Send it any clip, get back a file Telegram will actually accept.
