Video Compress

Compress a video using quality-based (CRF) or size-based (2-pass) encoding.

Process

1. Obtain input file

If the user did not provide a file path, ask for it with AskUserQuestion before proceeding.

2. Probe the source

ffprobe -v quiet -print_format json -show_streams -show_format "$INPUT"

Extract: duration (seconds), file size (bytes), existing video codec, audio bitrate. If ffprobe fails (file not found, not a valid video), report the error and stop — do not attempt encoding.

3. Determine mode from user intent
