Here are a few questions to help me better understand your request:
Converting media isn't just about changing a file extension from .MKV to .MP4. It involves balancing the "bitrate," "resolution," and "codec" to ensure the video looks crisp on everything from a smartphone to a 4K television.
Without a clearer specification, the request cannot be executed precisely. The recommended next step is to provide the original subtitle line at 01:56:51 and describe what “better” means (e.g., grammar fix, sync shift, simplification).
You have two main paths:
ffmpeg -i video.mkv -itsscale 1.9651 -c copy output.mkv sone443engsub convert015651 min better
| Error | Likely cause | Solution | |-------|--------------|----------| | Subtitles flash too fast | Wrong frame rate | Convert 25 fps to 23.976 | | Text has symbols like 饾棗 | Encoding mismatch | Convert to UTF-8 | | Subs appear but vanish | Overlap or zero duration | Tools → Fix overlapping times | | Timeline shows 015651 as frame | Subtitle was in frame count mode | Convert frames to time using fps |
Hardcoding is useful for platforms that don’t support subtitle tracks.
: Apply the engsub library to guarantee text alignments match the video timestamps perfectly.

The keyword describes a messy English subtitle file (maybe from sone443 ), needing conversion and time-shift fixing by ~1 minute, 56 seconds (or frame 15651) to become “better.”
Moving processing from the CPU to the GPU can significantly speed up conversion times for media files.
If your system encounters bottlenecks while running this specific configuration, try these immediate fixes:
H.264 for maximum compatibility across all phones, tablets, and TVs. The recommended next step is to provide the
ffmpeg -i input.mkv -map 0:s:0 subs.srt
Dedicated GPU hardware SIP cores; independent of graphics rendering 6x - 10x Faster
To understand the core utility of this phrase, we must first break it down into its constituent technical elements:
