Attach video to a Complexity message

Open Complexity and select an allowed model that advertises video input. Both configured capability and actual provider connection must support video.

The current video path requires HTTPS chat at openrouter.ai/api/v1 with provider type OpenAI or OpenAI-compatible. Catalog capability alone does not enable video on other endpoints or adapters.

Accepted MIME types are video/mp4, video/mpeg, video/mov, and video/webm. Attach the video to your own chat and wait for a clean virus scan. The general chat attachment ceiling remains 50 MiB.

An arbitrary external video URL cannot replace the attachment. If video is unavailable, select an authorized compatible model. Changing MIME labels does not bypass the restriction. Attachment admission and provider processing can still fail independently.
