01 / REFERENCE TO VIDEO
01 · Assign each reference a role. Use @image_1 for identity, @image_2 for the setting and @video_1 for movement.
02 · Describe one clear action, its progression and its ending. Say what must remain unchanged.
03 · Choose duration and resolution. Check the total credits before sending, then review the result in your library.
02 / @image_1 + @image_2
Use @image_1 for the product and @image_2 for the setting. A slow lateral camera move reveals the product on the table. Preserve its shape, colours and label. End with the product centred and fully visible. Soft ambient room sound, no speech.
03 / DX CREDITS
Without a reference video, only output seconds count. With video, billable seconds = output + the greater of input and output. All input clips are added together. Credits are rounded up once, on the total. Optional tools have their own prices.
04 / REFERENCE TO VIDEO
Up to 10 JPEG/PNG/WebP images and 5 reference videos. Each file: 10 MB maximum. Videos: 2–30 seconds each, 30 seconds combined. Prompt: 8,000 characters. This studio uses Reference to Video; keyframes, voice references and character elements are not enabled here. 4K is not offered.
No. References guide identity, setting and movement, but details can vary. Review faces, text, clothing, sound and the ending.
Video input is billable. For 10 seconds of output and 5 seconds of input, the billed duration is 20 seconds. With 15 seconds of input it is 25 seconds.
This integration is Reference to Video. A reference image is not a guaranteed first or last frame. The separate keyframe mode is not enabled.
