No problems traced to this repository code in these checks.

Reviewed as expected for a test run: attempted writes that failed, so nothing was written.

OSV scanned supported lockfiles; unpinned dependencies and unsupported formats are outside this check.

A short run cannot establish that code is safe.

Connections show IP addresses; proxies can hide the final hostname.

Tracing covers dispatched commands and their children, not the whole OS; guest root can interfere with tracing.

• Each operation is exposed as a standalone command, including trim-video: Real input produced the expected result: <guest-path>

  Source: Each operation is exposed as a standalone command (`pvk`, `trim-video`, `fade-video`, etc.).

  Input: <guest-path> trimmed from 1s to 3s

  Expected: trim-video writes the output file at the requested path

  Command: <guest-path> trim-video <guest-path> --start 1 --end 3 -o <guest-path>

  Observed: <guest-path>

Examples

• Trim a segment from a video with the pvk trim-video command: command completed successfully

  Source: README.md (Subprojects: PyVideoKit-CLI)

  Input: input.mp4 cut from 2s to 4s

  Expected: trimmed file written to the -o path

  Command: <guest-path> trim-video <guest-path> --start 2 --end 4 -o <guest-path>

  Observed: <guest-path>
