Conversion Notes
Video conversion re-encodes both the video and audio streams to fit the target container and codec. Resolution, frame rate, and aspect ratio are preserved by default. If the source uses a codec not natively supported by HEVC, a compatibility codec is chosen automatically. Conversion time scales with file duration and resolution — 4K files may take several minutes to process.
