ComfyUI Node
Preview Video (WebM)
Plays an image batch back as a scrubable WebM video inside the node. The file goes to the temp directory and is replaced on every run, so nothing is written to your output folder.

| Name | Type | Default | Description |
|---|---|---|---|
| images | IMAGE | The image batch to play back as a video. | |
| fps | FLOAT | 24.000.01–1000 | Playback frame rate of the preview. Defaults to 24, the native rate of most current video models. |
| quality | COMBO | near-lossless | Encoder speed against picture quality: 'fast' — realtime VP9, crf 40. Lowest latency, biggest file. 'balanced' — crf 34. Roughly twice as fast as the defaults SaveWEBM uses. 'high' — crf 28, more search effort. Use when you need to judge fine detail. 'near-lossless' — crf 15 and 4:4:4 chroma. Encoder artifacts stay below what you can see, so what you are judging is the model and not the codec. Slowest and by far the largest, which costs nothing here because the file is discarded next run. This only affects the throwaway preview, never anything you save. |
| mute | BOOLEAN | false | Leave the audio out of the preview without unwiring it. The track is skipped at encode time rather than silenced, so the file has no audio stream at all and the encode skips the resample too. Has no effect if nothing is wired to 'audio'. |
| audioopt | AUDIO | Optional audio track, muxed as Opus. Trimmed to the length of the image batch. Sample rates Opus does not support are resampled to the next supported rate. |
