Start with the job in front of you
A watermark can protect attribution, but a large mark in the wrong corner competes with the message.
A short test is usually faster than trying to fix a large final file after the fact. Keep the original nearby, name the exported version clearly, and change one setting at a time when the result matters.
Use a small, repeatable routine
Choose a quiet area of the frame, keep opacity and size restrained, and test it against the busiest shot.
The useful part of a browser tool is not simply getting an output. It is being able to reproduce the same result tomorrow, explain what changed, and notice when an input or assumption has changed.
Do one last check before sharing
Review the entire clip; a safe corner in one scene may cover a face in another.
If the result will be published, sent to a client, or used to make a decision, compare it with the source rather than trusting a filename or a successful download message.
Practical checklist
- Keep the original input until the output is checked.
- Test the workflow on a small sample first.
- Use clear names for exported versions.
- Review the result in the app where it will actually be used.
- Record important settings or assumptions.
