Formule & Méthode de Calcul
Transcode = Demux(Container) ➔ Decode(Video/Audio) ➔ Encode(New Codec) ➔ Mux(New Container)
A video file is just a container (like a box). Inside the box is a video stream and an audio stream. Conversion requires opening the box, translating the streams mathematically, and putting them into a new box.
Bonnes Pratiques & Conseils
- Mind the GIF Size: Converting a 1080p video directly into a GIF will create a massive, unusable file. Always reduce the frame rate (e.g., to 15 FPS) and scale the resolution down (e.g., 480px width) before encoding to GIF.
- Extract Audio for Podcasts: If you recorded a video interview but only need the audio, do not re encode the video. Simply use this tool to demux the MP4 and extract the pristine, untouched AAC or MP3 audio track instantly.
- Understand Codec Licensing: Certain highly efficient codecs (like HEVC/H.265) require expensive hardware licensing and cannot be natively encoded by open source web tools. Stick to universally supported formats like H.264 or VP9.
