Presets

Presets are the global transcoding recipes available across all Video Scribe fields. Manage them at Settings → Video Scribe.

Preset fields

Field	Description
Handle	Unique machine-readable ID, e.g. hero-vp9-720p
Label	Human-readable name shown in the CP
Extension	Output file extension, e.g. webm
MIME type	Full type string, e.g. video/webm; codecs="vp9"
ffmpeg args	Arguments passed between -i input.ext and output.ext
Notes	Optional description

Default presets

Handle	Output	Use case
hero-h264-720p	720p H.264 MP4, no audio	Background hero video
web-h264-1080p	1080p H.264 MP4 + AAC audio	General purpose
web-vp9-1080p	1080p VP9 WebM	Modern browsers, smaller files
audio-only-aac	AAC audio	Strip video track

Writing ffmpeg args

The ffmpeg args field contains everything between the input flag and the output filename. For example, for a 720p silent H.264 encode:

-vf scale=-2:720 -an -c:v libx264 -preset medium -crf 23 -movflags +faststart

ffmpeg receives: -i input.ext [your args] -y output.mp4

Common recipes

720p H.264, silent (hero background)

-vf scale=-2:720 -an -c:v libx264 -preset medium -crf 23 -movflags +faststart

1080p VP9 WebM

-vf scale=-2:1080 -c:v libvpx-vp9 -b:v 0 -crf 32 -c:a libopus -b:a 96k

1080p H.264 with audio

-vf scale=-2:1080 -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -movflags +faststart

Audio only (AAC)

-vn -c:a aac -b:a 128k
