How to make a semi-transparent garment fully opaque in a video
Upload the clip and tell Vizard Agent which garment should stop being see-through. Vizard Agent isolates the fabric with a clothing segmentation model, smooths the mask edges, tests several darkness curves on stills, and checks the fix holds steady across frames before processing the whole clip.
What do you type into Vizard Agent?
Say what must not change in the same breath. Vizard Agent treats that as a constraint on the mask rather than a note, and stating it up front is what keeps the correction confined to the fabric instead of spreading across the frame. A fix that also darkens the skin or the background is not a fix.
Prompt
What does Vizard Agent actually do?
Nearly all of the work is building and proving a mask; the actual correction is a handful of steps near the end. A correction that looks perfect on one still can flicker across frames, so Vizard Agent proves it holds on a short section before spending a full-resolution pass. In the session behind this article it:
- Probed the clip, cropped into the fabric where it was thinnest, and measured the actual colour values across different parts of the frame.
- Built a coordinate grid to fix the garment's position, then checked how it moved over time.
- Loaded a clothing segmentation model, visualised the mask, tuned it for speed, and smoothed the edges with a guided filter combined with colour-based detection.
- Tested three darkness and opacity curves on stills, then handled the hardest area, a translucent flap at the edge, separately.
- Rendered a three-second test to check the fix held steady across frames and validated it at four points in the clip.
- Processed all 1,180 frames in parallel at the full 2160x3840 and remuxed the original audio, delivering 19.66 seconds.
When does this not work well?
Fast motion blurs the boundary between fabric and skin, which resists a clean mask, and a dark garment against a dark background is the hard case. Vizard Agent increases opacity; it doesn't repaint what is behind, so very thin fabric may still read as fabric. Every frame is processed at full resolution, so long clips cost time.
Common questions
Will it change my face? No. Vizard Agent builds the mask around the garment and leaves the person outside it.
Can it fix only part of the clip? Yes. Give the timecodes and Vizard Agent processes that range instead of the whole clip.
Is the audio affected? No. Vizard Agent remuxes the original audio into the processed video, so nothing about the sound changes.
