Batch watermark videos with one reusable text or logo setup. Add up to 10 related clips, render every frame with Remotion in the browser, and download the finished videos one by one without uploading private media.
Add related clips that need the same text or logo treatment.
or drag videos hereThe queue retains one watermark setup and opens each local source for review. Videos export one at a time to control browser memory and download behavior; Remotion renders the active item without requiring real-time playback.
Specification reviewed:
Repeating the setup by hand makes a series feel uneven. The queue keeps your current watermark settings in the browser, so every related clip can use the same wording, logo scale, opacity, and position without sending the source media to a service.
Use one restrained mark across tutorials, listings, event clips, or a short campaign. Relative sizing helps the design stay visually consistent when the queue contains portrait, landscape, and square video. You can still open each item before export and move the mark when an important subject needs more room.
Add a focused set instead of repeatedly returning to a file picker. The batch watermark videos workspace shows which clip is active, waiting, or downloaded. A practical ten-file limit protects browser memory and makes it easier to inspect each result before a large publishing job moves forward.
Enter a copyright line, website, account name, proof label, or campaign note, or choose a PNG, JPG, or WebP logo. Size, opacity, rotation, shadow, outline, tiling, and placement are remembered locally. After one export finishes, the next waiting file opens with the same saved treatment.
Play and scrub the selected clip while the watermark remains over the picture. Check bright and dark scenes rather than trusting the opening frame alone. A soft shadow or outline can improve contrast, while a lower opacity keeps attribution visible without overpowering movement, faces, captions, or product details.
Remotion reads the source, renders the same watermark composition shown in the preview, encodes H.264, and packages the result as an MP4 file. There is no remote media conversion API behind the page, and the preview does not need to play during processing. Keep the tab open until the download begins.
Files in the queue are represented by temporary browser object URLs and remain on the device. Apply Watermark does not create an online project, remote preview, or cloud backup. Closing or refreshing the page clears the temporary queue, while downloaded copies remain in the normal downloads folder.
Browser video rendering is more demanding than image editing, so the workflow stays deliberate: prepare one related group, verify the watermark, then render and download each local copy in order.
Select up to 10 MP4, WebM, MOV, MKV, or MPEG-TS files. Remotion reads each selected source for the timeline and final render. Actual codec support still depends on the current browser and device. Divide a larger collection into smaller groups and keep the originals safely outside the downloads folder.
Choose text or a logo and set a size that remains clear on phones as well as larger screens. Use corner placement for gentle attribution or tiling for stronger proof protection. Scrub through the first clip and check that subtitles, faces, interfaces, and important action stay unobstructed.
Choose the available quality and start the export. Remotion decodes the file independently of real-time playback, draws the shared composition for each frame, and passes those frames to the browser H.264 encoder. It then packages video and compatible audio into an MP4 download without sending the source to a media server.
A successful download marks that row complete and opens the next waiting clip. Confirm its composition, make a placement adjustment if necessary, and export again. Batch watermark videos this way to keep one shared design while retaining a useful review point before every finished file.
The best queue contains clips with a common destination and visual purpose. Related footage can share one treatment; unrelated footage usually deserves separate settings and a separate review.
Apply one creator handle or campaign identity to a group of reels, shorts, and vertical previews. Keep the mark inside safe margins because platforms may cover edges with controls or captions. Review a phone-sized preview and avoid placing text where it competes with subtitles or calls to action.
Add a shop, agency, or listing identity before distributing walk-throughs and demonstrations. Consistent placement helps viewers connect separate clips to one source. Use enough contrast to survive changing scenes, but preserve the product details or rooms that a customer needs to evaluate.
A visible proof label can distinguish review media from final delivery, while a channel name can identify sample lessons. Agree on the final unmarked deliverables separately and retain the originals. When you batch watermark videos for review, use clear filenames so clients do not confuse previews with approved masters.
These short answers cover the practical details that matter most before you use the page.
No. Selection, preview, frame decoding, watermark rendering, encoding, and download happen in the browser. The site has no media upload API or cloud project storage. Refreshing or closing the page clears the temporary queue, so always keep your original and downloaded files in a safe local folder.
Browsers restrict automatic downloads, and video rendering uses much more memory and processing power than still images. One active export is more reliable, gives you a review point for every composition, and avoids holding several finished MP4 files in memory. The queue automatically moves to the next waiting clip after a successful download.
The output is an MP4 file encoded as H.264, so its container or codec may differ from the source. Remotion renders a compatible source audio track into AAC when the browser supports it. The export panel reports whether the completed MP4 includes source audio or is silent.
Yes. Settings are saved locally and reused as you move through the queue. Position and size are relative to the frame, which helps across different dimensions. You should still inspect each video because a consistent corner may cover a face, caption, or product in one particular composition.
