Prepare audio and video for AI workflows while preserving timestamps and source provenance. Learn stream selection, resampling, frame extraction, and checks for

Audio and video preparation determines what downstream AI systems actually receive. Containers may hold multiple streams, while decoding, filtering, and encoding affect the content passed to models. FFmpeg documents explicit stream selection and the distinction between copying a stream and transcoding it.
Preserve a link from extracted frames or audio segments back to their source timestamps. Check sample rates, channels, frame timing, and synchronization after processing. Work with permitted media and record transformations so a transcript or clip can be traced to the original recording.
No. Re-encoding can add computation and quality loss. Use stream copying where appropriate and verify the output requirements of the next stage.
