VellmHow to remake a video with your own photo in Vellm
By Vellm ·
Vellm's Remake a video mode takes a reference clip and a photo of the subject you want to use. The clip guides the movement and camera; the photo identifies the person, pet or character you want to appear.
Use it when the action is easier to show than describe. A particular dance, turn or gesture has timing that a short text prompt can leave open to interpretation. A reference clip gives the model more of that information, although the generated result can still change details.
Check the template library first
If Vellm already has the routine you want, a template provides a configured workflow with its own photo slots and listed credit cost. You can make the available Billie Jean dog dance without finding and uploading a motion clip yourself.
Choose a remake when you want to bring a different reference or experiment with a clip you recorded. Use clips and photos you have permission to use, and get consent from people who appear in your inputs.
Choose a short, readable reference
A useful first reference has one clear performer, a visible body and a camera that makes the action easy to follow. Several dancers crossing in front of each other create a harder subject-mapping problem.
Trim to the movement you want. A long introduction, reaction shot or end card adds material that does not help the task. If the moment you care about is a short turn, use that moment instead of the entire recording.
Look at the frame where the action begins. If the performer is hidden behind a prop or halfway out of view, choose a different section. The reference's own blur and occlusion can make it harder to judge what the new subject should do.
Vellm provides trimming for an uploaded clip. Model limits vary, so check the selected model's allowed reference and output lengths rather than treating a single duration as a limit for all remakes.
Add a photo that identifies the subject clearly
Use one clear photo of the subject who should star. For a pet dance, show the face, ears, body and paws. For a person, follow the framing requirements of the action and selected model.
The photo and video supply different information. A sharp portrait can establish a face, but it leaves more of the body for the model to infer. A clear full-body photo is more useful when the movement depends on the subject's outline and feet.
For a first attempt, avoid large differences between the input photo and intended character. Heavy costume changes and unusual body transformations add more things to judge if the result goes wrong.
Set up the remake
- Open Create and choose Remake a video.
- Add your reference clip and trim it to the section you want.
- Add the subject photo and choose a model available for that mode.
- Describe how the photo connects to the video. A remake needs a description, so Vellm fills in a short example once the clip and photo are both in. Edit it before you continue.
- Check the available settings, including resolution and Audio, then read the credits on Generate.
- Complete the permission step and generate. Review the result under the composer when it is ready.
The example is deliberately simple. Make it specific to your clip. For a dog remake with one performer, you might write:
Use the dog in @Image1 as the performer. Follow the main body movement, timing and camera framing in @Video1. Keep the dog's coat markings recognizable throughout the shot.
@Image1 refers to the photo and @Video1 to the clip you added. Check the labels on your file cards, then type @ in the description and choose the matching file from the suggestions. The numbers are separate for images and videos, and can change when you remove a file. See the step-by-step @ reference instructions if you are using several files.
This is an illustrative instruction, not a prompt tested on every model. If your idea relies on several references with different roles, consider Mix references and explain what each file supplies.
Review movement and likeness separately
Watch the clip twice. First, check the movement: did the animation follow the reference timing, and did the subject stay within the frame? Then inspect the face, coat patterns, clothing and body proportions for likeness.
If the movement is wrong, try a shorter or clearer reference before adding a long description. If the likeness is wrong from the opening, inspect the photo and subject mapping. If it changes during a fast turn, try a less extreme movement or another model available in the mode.
A completed result that needs creative changes is another paid attempt when you generate again. A generation marked as failed returns credits under Vellm's published policy; that is different from an automatic cash refund for a completed clip you dislike.
Check sound and save the result
Audio is off by default in Create. Supported models expose an Audio control, but enabling it does not promise the soundtrack from your reference. The pricing page explains credit purchases; the Generate button shows the cost of the current remake settings.
Download the clip you want to keep. Vellm's Create page says results are scheduled for deletion after 30 days. Save the reference, photo and settings with the result so you can make a useful comparison if you try another version.
