Can't open this video 🎞️

It's recorded in HEVC / H.265 and this browser has no HEVC decoder, so it can't be played or converted here.

Fixes (pick one):

• Easiest: open this same page on your phone and upload there — phones decode HEVC natively.
• iPhone: Settings ▸ Camera ▸ Formats ▸ "Most Compatible" → future videos are H.264.
• Samsung/Android: Camera ▸ Settings ▸ Advanced recording options ▸ turn off "High-efficiency videos (HEVC)".
• Or convert the file to MP4 (H.264) with any converter and upload again.

On devices with an HEVC decoder this app converts automatically — this browser just can't decode HEVC at all.
