--format <mp4|mov|gif|webm|webp|png-sequence|svg> | Container. Required; the output extension is not read. svg takes none of the options below. |
--backend <auto|cpu|gpu|browser> | Where frames are drawn. auto (default) uses the GPU, through an installed Chrome, Edge, Brave or Chromium, when that’s faster, and the CPU otherwise. gpu and cpu force one; browser renders in a tab you open. |
--tier <draft|review|final|master> | Encoder quality tier. |
--quality <0..100> | Encoder quality. Default 85. |
--supersample <1..4> | Render at a multiple of the output size and downsample. |
--alpha <preserve|flatten> | Keep transparency (mov, webm, webp, png) or flatten onto --flatten-color. |
--flatten-color <#RRGGBB> | Colour to flatten transparency onto. |
--codec <name> | Override the codec for the chosen format. |
--start <tick> --end <tick> | Export a tick range instead of the whole document. |
--step <ticks> | Ticks between frames. Default: one frame at the document’s frame rate. |
--parallelism <n> | Worker threads for frame rendering. |
--max-dimension <px> | Bound the longer side of the output. |
--full-resolution | Render at the document’s size. Conflicts with --max-dimension. |
--progress-preview <file.png> | Where to write the progress sheet. |
--no-progress | Don’t write a progress sheet. |
--no-verify | Skip decoding the result to verify it. |
--no-audio | Leave out the document’s sound. |
