Images to Video Maker Guide

The question that actually matters

People search for an images to video maker because they want motion from a single photo without losing subject identity. The real need is a repeatable workflow that keeps faces, clothing and backgrounds stable across frames while adding controlled camera moves. Flixly handles this through the Image to Video tool paired with current models.

Direct answer

Upload one reference image to the Image to Video page, select Seedance 2.0 or Kling 3.0, set motion strength between 0.4 and 0.7, and generate 4-second 1080p clips. Credit cost is 12 per second on standard settings.

Layers most guides skip

Reference strength vs motion strength

Reference strength locks the subject. Set it to 0.85 when the input photo contains a specific face. Lower it to 0.6 when you want the model to reinterpret clothing or background.

Motion strength controls camera path. Values above 0.8 create fast pans that often break consistency. Keep it under 0.65 for talking-head or product shots.

Frame rate and duration tradeoffs

All models output 24 fps by default. Extending duration past 6 seconds increases drift on Seedance 2.0. Veo 3.1 holds structure longer but costs 18 credits per second.

Audio layer handling

Lip Sync Video and Motion Poster accept the same reference image. Generate the silent clip first, then add voice with Voice Cloning at 48 kHz.

Model comparison table

Tradeoffs nobody mentions

Seedance 2.0 gives the cleanest faces at 0.5 motion strength but struggles with complex backgrounds. Kling 3.0 handles crowd scenes better yet introduces slight color shifts after frame 80. Veo 3.1 is the most stable for product rotation but rejects inputs wider than 3:2 aspect ratio.

If your reference image contains text, all current models distort letters. Pre-process with AI Photo Effects at 2x upscale first.

Step-by-step workflow

1. Open the Image to Video page and sign in. Select the exact reference photo from your library.
2. Choose the model from the dropdown. Start with Seedance 2.0 for first tests.
3. Set reference strength to 0.82 and motion strength to 0.55. These numbers balance identity and movement on most portraits.
4. Enter a short motion prompt such as "slow left pan, slight zoom in" limited to eight words.
5. Pick 4 seconds duration and 1080p output. Check the credit preview before confirming.
6. Generate the clip. Review the first 24 frames for face drift using the built-in scrubber.
7. If drift appears, return to step 3 and raise reference strength by 0.05 increments.
8. Download the final MP4 or send it directly to Shorts Generator for caption overlay.

When to chain tools

After the base clip is ready, send it to Video to Video for style transfer or to Lip Sync Video if dialogue is required. Each handoff keeps the original reference locked.

Decision rule worth remembering

Start every project with the highest reference strength that still allows the needed camera move. Adjust downward only after the first test clip shows unwanted rigidity.

FAQ

What resolution should the input photo be for best results? Use images at least 1024 pixels on the short side. Lower resolutions force the model to invent detail and increase drift.

How many credits does a typical 5-second 1080p clip cost? Seedance 2.0 charges 60 credits. Kling 3.0 charges 75 credits. Prices are listed on the generation screen before you confirm.

Can I use the same reference image for multiple clips in one project? Yes. Upload once, then reference the saved asset in each new generation. The system keeps the file for 30 days.

Does the tool support 9:16 vertical output for shorts? Select 9:16 in the aspect ratio menu. Seedance 2.0 and Kling 3.0 both accept it; Veo 3.1 currently does not.

What happens if my prompt contains camera terms the model does not recognize? The system falls back to a gentle zoom. Rewrite the prompt using only the listed motion keywords shown in the interface tooltip.
