Video too large to preview
The video preview endpoint refused the file because it is over the inline preview size cap (about 200 MiB). Product text asks you to create a download link instead.
Why this happens
Hardcoded VIDEO_PREVIEW_MAX_BYTES protects browser memory and bandwidth. Full download via grant still follows normal download rules. Video Mod / tier “show video” toggles are separate gates.
Diagnose and fix
1. Visitor: use Create download link / Download — not the in-page player.
2. Admin: cap is a code constant — not raised in Users & limits.
3. Confirm Video Mod and tier video toggles if smaller videos also fail to preview.
4. Same family as image/audio/document “too large to preview.”
