Title: Google AI Studio MP4 upload issue: “Token count failed” / HTTP 500 even with single video

Hi, I’m having a persistent Google AI Studio issue with MP4 video uploads.

When I upload MP4 video files, AI Studio shows:

“Token count failed”

I also receive this error:

“Http response at 400 or 500 level, http status code: 500.”

What I’ve tried:

  • Deleted failed uploads and re-uploaded
  • Refreshed the AI Studio page
  • Created a new prompt/session
  • Tried uploading only one video at a time
  • Tried smaller batches
  • Tested across multiple MP4 files and folders
  • Workspace Support confirmed my AI Expanded Access is active

The issue still happens even with a single MP4 file in a fresh AI Studio session.

This appears to be an AI Studio video parsing/token-count failure, not an access/subscription issue.

Has anyone seen this before, or is there a known workaround for MP4 files that trigger token count failure?

I can provide screenshots showing the red “Token count failed” upload cards and the HTTP 500 message.
