## What is Vlo?

Vlo is [Wery](/en/experts/wery)'s short video generation expert, responsible for generating short video clips from text, pictures, multiple pictures or mixed reference materials. Perfect for 5-15 seconds of action, footage, product demonstrations, mood clips, or social media footage.

## Generation modes

Vlo automatically selects the mode based on the material.

- Text: Generate videos from pure text.
- Single image: Generate video from a single reference image.
- Multi image: Multiple images as continuous material or style reference.
- Almighty reference: Mixed image, video, audio, or explicit @Image 1 reference.
- First and last frames: The first and last frames need to be clear, suitable for transitions or action arcs.

## How to write video prompts

Video prompt words require more action and time than picture prompt words.

- Action: What the subject does in a few seconds.
- Lens: zoom in, surround, follow, handheld, fixed, overhead shot.
- Time beats: What happens at the beginning, middle, and end.
- Light and material: determine the texture of the picture.
- Proportions and Platforms: 9:16, 16:9, 1:1 vary in composition.
- Sound: Whether to generate audio, audio only uses a generic non-copyright description.

## Confirmation and parameter table

The production cost of short videos is higher, and Vlo should first display the confirmation plan after actually extending the prompt.

- Confirm the final prompt.
- Confirm duration, aspect ratio, resolution, video number and generate audio.
- Confirm each reference URL and role.
- Confirm the title and output purpose.
- After the user confirms, submit the real generation.

## FAQ

### Q: What length of video is suitable for Vlo?

Better suited for short clips under 15 seconds. The long video script and storyboarding was given to Nolan.

### Q: After uploading the picture, does it have to be a Tusheng video?

Usually yes, but if you are mixing multiple assets or explicitly referencing @Image 1, you may go into mixed reference mode.

### Q: Why do I need to confirm the prompt?

The cost of video generation is high, and the expanded actions, shots, and parameters require user confirmation before execution.

### Q: Can I generate a video with sound?

Audio generation can be turned on according to parameters, but the sound description should be universal and non-copyrighted.

### Q: Can I edit it after it is generated?

The results can be handed over to Komp for subtitles, proportions, credits, and multi-platform versions.
