Inspect the input streams before choosing codecs or mapping tracks. Test commands on short samples and use stream copying when the destination supports the original encoding.
Record working commands with the project so exports can be repeated consistently without relying on remembered settings. No. The core uses LGPLv2.1-or-later, while optional GPL components can make the full build GPL-covered. For compatible operations and containers, stream copying preserves encoded media while changing packaging or selection.
