FFQueue

Create jobs from files and reusable presets, select mapped streams and an output filename, then review the graphical console or saved HTML log. External audio/subtitle detection and time-limited filters support recurring assemblies. Unique-name suggestions append a number; an existing output can cause a skipped job when overwrite is refused. Thumbnail generation is different: the documentation says existing thumbnails are silently overwritten. Batch creation normally fails when a required stream is missing unless that requirement is relaxed. Optional same-codec copying bypasses re-encoding filters and does not apply to two-pass jobs or advanced cuts.
