How do you choose compatible audio and video output formats?

A file extension alone does not describe all of a media file’s properties. Playback depends on the container and the encoded streams inside it.

Define the target before rendering

Choose an output profile based on the intended browser or publishing destination. Record the container, video and audio codecs, dimensions, frame rate, and audio sample rate. Verify current destination requirements instead of assuming one profile works everywhere. Treat these choices as part of the pipeline’s output contract.

Inspect the actual artifact

Probe the rendered file and test it in the intended player. Confirm that audio is present and that duration and dimensions match expectations. A renamed extension does not convert the underlying format. Use short fixtures with different input properties to reveal conversion problems before processing longer jobs. Keep a known-good output sample so later rendering changes can be compared against a working baseline.
