ffmpeg -i input.ass output.srt Or use online free converters (but offline tools are safer). Q1: Is there a free video converter that keeps subtitles intact? Yes: HandBrake , FFmpeg , Shutter Encoder , and Avidemux (with limitations) all support subtitle passthrough. Q2: Can I convert only a portion of a video without re-encoding? Absolutely. Use LosslessCut or FFmpeg with -c copy . This is called "smart rendering" or "lossless trimming." Q3: What does "min free" mean in my search? It likely refers to "minimum free space" — ensuring you have enough hard drive space before converting, or "free as in no cost" for the conversion tools. Q4: My converted file starts at 01:58:56 but audio is choppy. Why? This happens when cutting on non-keyframes. Solution: Add -noaccurate_seek in FFmpeg or use HandBrake's "smallest" or "nearest" keyframe options. Q5: How do I permanently embed (burn) English subtitles into the video? In HandBrake: Subtitles tab → select track → check "Burn In." In FFmpeg: use the subtitles filter as shown above. This makes subtitles part of the video image — no player settings needed.

Solution: Use a subtitle editor to shift all timestamps back by -01:58:56. Problem 2: Audio/Video Mismatch After Conversion Some containers (like MKV) have gradual timestamp drift. Solution: Re-encode with -async 1 in FFmpeg or use HandBrake's "sync" options. Problem 3: "Convert015856" Not Recognized by Software Most GUI tools require timecodes in HH:MM:SS format.
