Select inputs
Add the elementary video and audio files that belong to one programme and choose their intended timing/order. Input extensions are hints; SmartCut64 probes stream codec information before muxing.
Choose a legal container
Available destinations include supported TS/M2TS/REC, MPEG program stream, Matroska, MP4/MOV, WTV/DVR-MS and MXF workflows. The exact codec combination determines which destinations are valid.
No implicit transcode
Multiplexing packages compressed streams; it does not decode and change their codecs. If a stream is incompatible, choose another container or create a supported transcode first.
