Remove the Runway watermark from your video

Even on Runway's paid tier where the visible watermark is removed, the file still carries metadata flags. Our pipeline strips both the watermark layer and the metadata fingerprint.

What Runway writes into every export

Which platforms scan for it

Runway content gets detected by: Instagram, TikTok, YouTube. Each platform has its own scanner — but they all look for the same signatures.

How Calabi removes it

1. Strip the metadata container — ExifTool wipe of every group, including the Content Credentials JUMBF block.
2. Break invisible patterns — controlled re-encode with light noise injection defeats pixel-domain watermarks.
3. Strip the encoder fingerprint — bitstream filter removes the editor's signature so the file's encoding profile matches a real phone.
4. Inject phone identity — Make / Model / Software / GPS / capture timestamp written across every metadata field.
5. Forensic proof card — same scan platforms use, run on the output. Green pill = clean.

Frequently asked

How do I remove the Runway watermark?

Upload your file at calabilabs.com/app. The pipeline strips Runway's Runway watermark in corner (free tier), generator metadata, and encoder signatures, then injects authentic phone-capture identity. The forensic proof card shows you exactly what was removed before you download.

Does the Runway watermark survive cropping or re-encoding?

Yes — that's why it's so hard to defeat with consumer tools. The watermark is embedded in the file's metadata container and encoded into the bitstream. Neither survives a regular crop or basic re-encode unless the tool specifically targets them.

Will the cleaned file still look the same?

Yes. The visible content is preserved. Changes happen at the metadata level (invisible) and at the pixel level (imperceptibly small noise + perspective shifts that defeat fingerprinting but never affect what you actually see).

Which platforms detect Runway content?

Instagram, TikTok, YouTube all scan for Runway's watermark signatures before a human ever sees the post.
