A free browser workflow blurred the background after conversion, but preview, edge quality, and export controls produced important limitations.
Can the tested free web workflow blur a vertical video background and export a usable result? The Click Test tested the source file, diagnosed a black HEVC/HDR preview, converted it to H.264 MP4, applied blur, changed export settings, and inspected the result.
What worked and what did not
- Load the original HEVC/HDR source.
- When the preview remains black, convert to H.264 MP4.
- Apply the background blur and inspect subject edges.
- Change resolution and frame-rate controls.
- Check the exported dimensions and audio/video sync.
How the result was judged
- The H.264 conversion restored the preview.
- The blur worked, although subject edges looked fuzzy.
- The output still measured 720×1280 despite selecting a reduced resolution.
- Frame rate was lower, while audio and video remained synchronized.
The workflow produced a visible blur without paid editing software.
Limits to keep in mind
The original format failed to preview, edge quality was imperfect, and the resolution control did not change the final dimensions in this test.
The Click Test Conclusion
The result was usable in some respects but had meaningful format and export limitations.
