- Convert time into samples or filters
Example
Input
clip.mp4
Output
倒放规划 ffmpeg -i clip.mp4 -vf reverse -af areverse -c:v libx264 output.mp4 倒放必须重编码：解码帧顺序与时间戳需要重建 音频同时 reverse 才能保持同步
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.
