Civitai now reads metadata natively from compatible videos saved with ComfyUI Video Saver v1.27.0 or newer.

This extension is no longer needed when native detection works. It remains an optional fallback for older videos or missing metadata, and now skips matching prompts, settings, and exact resource versions already detected by Civitai.

For ComfyUI videos, the companion Video Saver nodes support Civitai’s native metadata detection and this extension’s fallback features:

Tired of copying and pasting parameters like prompt and LoRas used when uploading a video on Civitai??

It's been published on FireFox now: https://addons.mozilla.org/en-US/firefox/addon/civitai-video-metadata-assist/

Use my image-saver fork video-saver to save videos with proper lora and prompt metadata: https://github.com/diodiogod/ComfyUI-Video-Saver

Then install the browser extension, it will show up automatically on upload page, all you need is drop the video (with metadata) and it will fill the forms for you:

More importantly, there is already a PR to add native MP4 and WebM metadata detection directly to Civitai:

https://github.com/civitai/civitai/pull/3307

If you want proper video metadata support on Civitai, consider leaving a reaction or constructive comment on that PR. A little polite pressure might help show that people are waiting for it.

Hopefully they merge it and this extension eventually becomes unnecessary.
