What should I know about the result?
Estimated size is a target, not a guarantee. The result shows actual bytes and reduction. Smaller targets can reduce quality; an already optimized video may not shrink. Output is H.264/AAC MP4 at 30 FPS. Only the first video and audio tracks are kept; subtitles and extra tracks are not preserved. Processing can take several minutes and uses device memory. The engine downloads about 31 MB on first use.
