Add text, logo, image, or dynamic watermarks to multiple videos in Wondershare UniConverter. The current Add Watermark workspace keeps several clips in one Playlist, lets you reuse a setup with Apply to All, and finishes with one File Location and Add Watermark export action.
Current desktop UI confirms Playlist-based multi-video editing, Image Type, Text Type, Opacity, Customize, Dynamic Watermark, Apply to All, File Location, and Add Watermark controls.
The current interface does more than open several files. Playlist management, Apply to All, and one output location reduce repeated setup when the same branding treatment belongs across multiple videos.
The current Add Watermark panel separates Image Type and Text Type, provides an Opacity control, offers Customize and Dynamic Watermark styles, and includes Apply to All for repeated settings across the Playlist.
Select Image Type and click Add Image when the Playlist needs a logo, brand graphic, channel mark, or other image-based watermark.
Select Text Type for a channel name, copyright line, draft label, campaign tag, or other editable wording. The current UI shows three text-entry rows, matching the documented text-watermark workflow.
The current Windows guide states that only the first text watermark can be used as a dynamic watermark.
The current Styles panel offers Customize and Dynamic Watermark. Use Customize when a fixed placement is enough; choose Dynamic Watermark when you want the mark to move.
Apply to All is the control that turns one configured watermark into a repeated batch treatment across the loaded Playlist. Use it only after the current video looks right.
UniConverter Desktop keeps the main batch watermark controls in one workspace, including the Playlist, image and text watermark options, opacity, dynamic watermark settings, Apply to All, output location, and processing controls.
| Current UI Control | What It Does | Batch Use |
|---|---|---|
| Playlist | Keeps multiple loaded videos inside the same Add Watermark workspace. | Switch between clips to check how the watermark looks on different framing and content. |
| Image Type + Add Image | Adds an image-based watermark such as a logo or brand graphic. | Useful when the same logo needs to appear across a group of videos. |
| Text Type | Provides three text-entry fields in the current interface. | Use them for copyright text, channel names, campaign labels, review marks, or other repeated text. |
| Opacity | Adjusts how visible the watermark appears, using a 0–100 control. | Preview both bright and dark scenes before reusing the same opacity across several videos. |
| Customize | Uses a fixed watermark style and placement. | A practical choice when one stationary watermark position works across the selected videos. |
| Dynamic Watermark | Creates a moving watermark and enables the related Position and Speed controls. | Preview the movement on representative clips before applying the setup across the Playlist. |
| Apply to All | Reuses the current watermark setup across the loaded videos. | Check videos with different aspect ratios or subject positions before applying one setup to the full batch. |
| File Location | Sets the folder where processed videos will be saved. | Choose a clear destination so the finished files can be checked against the originals. |
| Add Watermark | Starts processing after videos have been loaded and the watermark has been configured. | The button remains unavailable in the empty workspace until media is added. |
Current interface note: The September 2026 UniConverter Desktop Add Watermark workspace supports image and text watermarks, fixed or dynamic styles, multiple videos in one Playlist, and the Apply to All batch control.
Follow the current Add Watermark interface: build the Playlist, configure Image Type or Text Type, reuse the setup with Apply to All when appropriate, then set File Location and process the batch.
From UniConverter Home > Video, open Add Watermark. Add or drag the first video into the workspace, then use the file-add control to load the rest. The left-side Playlist keeps the current batch visible.
For a logo, select Image Type and Add Image. For text, select Text Type. Adjust Opacity, keep the mark fixed with Customize, or choose Dynamic Watermark to use Position and Speed.
Use Apply to All when the same setup belongs across the Playlist. Review representative clips, choose File Location, then click Add Watermark to process the watermarked outputs.
Batch watermarking works best when several videos need the same branding logic but still deserve a quick review before delivery.
Add the same logo, channel name, or series mark across recurring episodes, product clips, or campaign videos while reviewing placement against different shots.
Add a visible draft, review, or client-preview mark before sharing working cuts. Watermarking adds attribution but does not guarantee that a file cannot be copied or edited.
Place a company logo, internal-use label, or course identifier on batches of tutorials, onboarding clips, demonstrations, or support videos.
Prepare multiple branded exports for recurring social campaigns, creator content, partner handoffs, or scheduled publishing without rebuilding the watermark from scratch for every clip.
One shared watermark can look different across source videos. Review representative clips before final delivery.
Load multiple videos into the Add Watermark Playlist, choose Image Type or Text Type, adjust Opacity and watermark style, use Apply to All when appropriate, set File Location, and process the reviewed batch.
