Decide whether the logo is for viewing or export
VideoLAN desktop 3.0 logo documentation describes playback overlay controls and command line methods. It explicitly distinguishes runtime logo display from a logo filter used during transcoding to save or stream a result containing the mark. Seeing an image over a video in the current player is therefore insufficient evidence that the source file itself has been rewritten. Start with the intended result, such as a local preview or a portable branded output.
Review the placement on a short sample
For an original example, use a permitted demonstration clip and a logo you are authorised to use. Check its position and opacity against both bright and dark scenes, and ensure it does not cover necessary captions or edge information. If a permanent output is required, use the documented transcoding path with a compatible codec and container and a new destination name. Keep the original clip and the logo asset available for revisions rather than replacing the only source copy.
Verify the result outside the preview state
Open the newly created output in a separate player or a playback state without the local overlay enabled. Check that the mark is present where expected and that the sound, duration and framing remain suitable. If the mark appears only in the original VLC preview, revisit whether the processing path actually included it. Do not infer an embedded edit from a saved player preference or from a destination filename which merely contains the word branded.
