ASSA Resolution Resampler

Resample ASSA subtitle styles and positions from one video resolution to another, so subtitles look correct at a different resolution.

Menu: ASSA → Resolution Resampler...

How to Use

1. Open a subtitle file in ASS/SSA format.
2. Go to ASSA → Resolution Resampler… to open the resampler dialog.
3. The Source resolution is read from the subtitle header (PlayResX / PlayResY).
4. Set the Target resolution — if a video is loaded, it is used as the default.
5. Choose which elements to resample (margins, font sizes, positions, drawings).
6. Click OK to apply the resampling.
