Hardcoded subtitles (burned-in) versus softsubs (toggleable) change how you approach conversion.
To achieve a superior result for a file of this specific length, follow these three pillars of video optimization: 1. Choose the Right Codec (H.265 vs. H.264)
Don't use a "one size fits all" bitrate. Use Constant Rate Factor (CRF) encoding. A CRF value of 18–22 is generally considered "transparent," meaning the human eye cannot distinguish it from the original source. 3. Subtitle Preservation
Converting a feature-length file of over two hours requires efficient codecs to ensure the file size doesn't explode while maintaining 1080p or 4K clarity. How to Get a "Better" Conversion
