Workflow Playbook
Choose a delivery target for a video or animation, extract only the needed audio or video stream, and convert short motion assets while recording quality and compatibility trade-offs.
Hubs
Keep the original file and write down what the recipient actually needs. A player preview needs a video stream; an audio editor needs sound without the picture; a browser animation may need WebM or MP4; and a short, silent preview may still call for GIF. The filename extension alone does not define a usable container and codec combination.
Use video-stream-extractor when the existing coded streams are suitable and you only need to separate them. Stream copy avoids a fresh transcode, but it is not a compatibility guarantee. For audio-only work, choose video-to-wav or video-to-flac when source fidelity matters, and choose video-to-mp3, video-to-aac, or video-to-opus when a compact delivery file is the better fit. A lossless output cannot undo compression already present in the source.
Use gif-to-mp4 or gif-to-webm when a video container is more useful than a silent image sequence. Use mp4-to-gif for a short preview and accept the GIF palette and duration limits. If the source is animated WebP or APNG and the consumer expects MP4, use animated-webp-apng-to-mp4. Every re-encode can alter detail, timing, color, or size, so keep a comparison copy.
Re-probe the result and test it in the destination player or editor. Check stream presence, duration, frame rate, dimensions, audio channels and sample rate, synchronization, visible artifacts, and file size. For broader audio cleanup or loudness work, continue with audio-convert; for general media inspection, use video-utility; for packaging without a fresh encode, see stream-copy-remux-and-media-packaging when that workflow is the better boundary.

Use the stream extractor to probe whether the input has usable audio and video. Keep the video path when the visual track is part of delivery; choose stream copy for separation when compatible, and do not assume that every container or player accepts the original codecs.
For an audio-only handoff, select WAV or FLAC when preserving source detail is the priority, or MP3, AAC, or Opus when a compact delivery file and platform support are more important. Set bitrate, resampling, and channels only to the extent the destination needs.
For a picture-bearing delivery, use GIF to MP4 or GIF to WebM for a video container, MP4 to GIF for a short silent preview, or animated WebP or APNG to MP4 when the consumer expects MP4. Keep the frame range and quality settings aligned with the destination.
Keep a video stream when motion, framing, or visual playback is required. If the handoff is sound-only, choose a video-to-* exporter. If the coded streams are already suitable and only separation is needed, use video-stream-extractor to avoid another encode.
Choose WAV or FLAC for PCM or lossless delivery of the source signal, and MP3, AAC, or Opus when compression and target support matter. Lossless output preserves the input as received; it cannot repair a lossy source.
Use MP4 or WebM for video playback and web delivery. Use GIF for a short, silent preview with a limited palette. Convert animated WebP or APNG to MP4 when a video container is required instead of an animated image.
Re-check stream presence, duration, frame rate, dimensions, audio channels and sample rate, file size, and playback or import in the destination. A changed filename extension is not evidence of a valid conversion.
Run the stream check on the result, then open or import it in the real destination. Compare duration, dimensions, frame rate, audio presence, sync, visual artifacts, and file size with the stated acceptance notes; preserve the source if the trade-off is not acceptable.
