Real Burning Bridges AI Results: Photo to 15-Second Video

The test portrait

The same generated portrait was used in both tests. You can compare the input with the lead's face during movement and turns.

Test 1: one portrait and a written scene prompt

Inputs

One portrait and a scene prompt; no reference frames or video.

Model calls

One Seedance 2.0 Mini video task through KIE.

Recorded time

3 minutes 22 seconds (201.906 seconds), from local job creation to completed video with audio.

Output

15.041667-second MP4, H.264 at 864 × 496 pixels, generated at the 480p setting; 15-second AAC soundtrack attached afterward.

Credits

40 credits deducted from an isolated test wallet. At today's $9.99 per 100-credit pack, 40 credits have a nominal pack value of $3.996; this is not a standalone $4 purchase option.

The model produced a warm lounge scene and gestures from the prompt. It did not reproduce the original reference performance exactly. This test demonstrates a completed video, not frame-for-frame scene fidelity.

Test 2: earlier nine-frame storyboard workflow

Inputs

The test portrait and nine scene keyframes, followed by a video prompt.

Model calls

Nine Nano Banana image tasks, then one Seedance 2.0 Mini video task: ten tasks in total.

Recorded time

13 minutes 2 seconds (782.061 seconds), from local job creation to completed video with audio.

Output

15.041667-second MP4, H.264 at 864 × 496 pixels with a 15-second AAC soundtrack.

Credits

40 credits deducted from an isolated test wallet under the site's 480p test pricing. The supplier's total cost for the ten calls was not verified from a billing statement.

This was an earlier experimental workflow and is no longer the generation path. The footage and soundtrack were based on externally sourced reference material; this demonstration does not establish ownership or permission to republish its scene, supporting likenesses or music. Check your own usage rights before sharing any output.

What these measurements mean

Elapsed time includes provider generation, polling and soundtrack processing in the local test runner. Each result is one successful test, not an average, success-rate estimate or service-level promise. Provider dollar charges were not reconciled with a billing statement and are not presented as verified costs.

New accounts receive 30 welcome credits once. A 480p video costs 40 credits and a 720p video costs 60 credits, so the welcome grant alone does not cover a full generation. The minimum purchase is 100 credits for $9.99. Downloads and soundtrack processing do not require a separate credit payment.

Review the entire output for identity drift, extra gestures and changes to supporting people. AI generation can change facial details and scene content.
