Presets

Presets bundle codec, bitrate, quality, and container settings for common delivery targets. Use them with the Export builder.

Using presets

await ffmpeg.exportVideo()
  .input("raw.mp4")
  .preset("youtube_1080p")
  .faststart()
  .output("youtube.mp4")
  .execute();

Overriding preset settings

Preset values can be overridden by chaining methods after .preset():

await ffmpeg.exportVideo()
  .input("raw.mp4")
  .preset("youtube_1080p")
  .crf(22)          // override CRF from preset's 18
  .audioBitrate("128k")  // override audio bitrate
  .output("output.mp4")
  .execute();

Custom encoding without presets

await ffmpeg.exportVideo()
  .input("raw.mp4")
  .videoCodec("h264")
  .crf(20)
  .videoBitrate("4M")
  .audioCodec("aac")
  .audioBitrate("192k")
  .pixelFormat("yuv420p")
  .output("custom.mp4")
  .execute();
