Video Tools Basics
Generate, trim, upscale, extract frames, and combine video clips in ViraFlow.
What video tools are for
Video tools help you create and continue video material on the canvas.
Use them after you have a text idea, an image, a storyboard frame, or a short clip that should become part of a larger workflow.
Create a Video node
Start with a Video node.
You can:
- upload a video
- choose a video from
Assets - generate a video from text
- generate a video from an image reference
- use a first frame, current frame, or last frame when the workflow needs frame control
- connect image, video, text, or script context when the selected model supports it
The visible settings depend on the selected model. Common settings include model, aspect ratio, resolution, duration, audio, and prompt.
Generate a short test
Video generation costs more credits than small edits. Start with one short test.
- Select the Video node.
- Choose the model and visible settings.
- Use one clear motion prompt.
- Generate one result.
- Preview it before making more versions.
If the clip is close but not right, adjust the source image or prompt before changing too many settings.
Improve or reuse a video
After a video exists on the canvas, you can use video actions:
| Tool | Use it when |
|---|---|
| Upscale | The clip works, but the quality is too low |
| Frames | You want storyboard frames or still references |
| Trim Video | You only need a short section of a longer clip |
| Download | You want to save the clip outside ViraFlow |
| Save to Assets | You want to reuse the clip in another canvas project |
Frame extraction and trimming are designed for shorter source videos. If a video is too long, trim it before using it as a working source.
Combine clips with Video Composer
Use Video Composer when you have several completed clips and want one short
export.
You can:
- add completed video clips
- upload local videos into the composer
- preview the sequence
- split a clip
- trim the start or end
- move clips on the timeline
- mute or keep original audio
- export the result
The composer is marked beta. Keep exports short and use fewer clips when an export fails. The current canvas flow is best for short creator videos, not long editing projects.
Keep video work readable
Place video results near the image, script row, or source clip that created them. Save the best clips to assets. Move failed tests away from the main path or delete them.
