Transcode Task

Transcode tasks process local video or audio files. Entry path: plus icon on the left, then Transcode.

Transcoding is handled by FFmpeg. It is useful when a file needs to be easier to play, share, edit, or archive. It can run as a standalone task or after a download task.

Scenario Recommended Choice
Keep only audio after a download Choose Audio in the download task, or transcode to MP3 or M4A.
Video is too large to share Transcode to H.265 MP4 or reduce size to 1080p or 720p.
Continue editing in video software Use MOV H.264 / AAC, or another format your editor supports.
Publish for web playback Use MP4 H.264 / AAC or WebM VP9 / Opus.
Preserve high-quality audio Use FLAC, or WAV when further editing is needed.
  1. Click Select File.
  2. Choose a local video or audio file.
  3. Wait for XiaDown to check it.
  4. Choose size, container, and codec.
  5. Click Start.

The task moves to Running. After completion, open Tasks and Files to preview, open the folder, or transcode again. You can also start from Files by selecting a media file and clicking Transcode in the details area.
