Client-Side Frame Rate Modification
Unlike simple browser preview playback controllers that artificially adjust the HTML5 media stream rate, this tool permanently burns your new defined framerate and timescale constraints instantly into the MP4 file.
How does Presentation Timestamp (PTS) calculation work?
Under the mathematical hood, our WebAssembly FFmpeg processor evaluates the -filter:v setpts=INVERSE_RATIO command logic to modify exactly when physical pixel frames trigger playback timing protocols in hardware. Additionally, utilizing the inverse atempo audio filter mapping, human vocal waves remain recognizable instead of being destroyed by brute-force algorithmic truncating.
