What this tool does
- Check parameters before transcoding
- Convert time into samples or filters
Example
Input
voice.wav
Output
ffmpeg -i input -c:a aac output.aac
Computes an assertable plan or sample range. It does not touch devices or transcode files.
Frequently asked questions
Does it process the file?
No. It returns a plan, command, or sample range and never decodes media.
May numbers be strings?
Yes. Numeric strings from text controls are parsed as numbers.
Does it match ffmpeg exactly?
Times, filters, and bitrate formulas are deterministic; container overhead can still differ.
