Fix a Bulin 47 AI Video: Diagnose Photos, Motion and Output

Start with the local photo preview

If no image appears after selection, check whether the original opens in your device’s image viewer. Confirm that you selected the intended file rather than a shortcut or a cloud item that has not downloaded. Try a normal supported image export while retaining the original.

If the preview shows the wrong crop, use an image editor to make a separate portrait version. Keep the face and the action area visible. Repeatedly changing a scene prompt cannot fix a crop that already removes the shoulders before any generation occurs.

Check the reference before blaming the model

Play the motion file from beginning to end outside this site. Look for cuts, a second performer taking over the frame, missing hands, or a camera move that obscures the body. Write down the exact moment that becomes unclear.

Compare that moment with the photo’s pose. If the reference turns away but the picture only shows a frontal face, identity during the turn becomes a separate review question. Try a simpler permitted reference for a later comparison. Do not assume that a different resolution can resolve a movement ambiguity.

Use a controlled troubleshooting sequence

Troubleshooting needs a record of what changed. Save your source files, scene brief, settings, and any actual result. Keep a short note beside each draft so you can avoid repeating the same unclear experiment.

If a future provider reports a failed task, read its actual status before retrying. A slow or uncertain response is not permission to submit another potentially billed job. Use that service’s task history or support path to establish what happened first.

1. 1. Identify the last stage that actually succeeded.
2. 2. Confirm that the original photo and motion video open normally.
3. 3. Review subject visibility, crop, pose, and reference continuity.
4. 4. Change one input that addresses the visible defect.
5. 5. Compare a real result with the previous version only when a generation has occurred.
6. 6. Check the task record before any potentially paid retry.

Inspect face and hand defects at their transition

A face may look correct in the first frame and drift during a head turn. Hands may merge with clothing only at the fastest gesture. Pause near the moment where the defect starts, then watch it again at normal speed. The timing tells you more than a single flattering thumbnail.

For a face problem, compare clarity and angle in the source image. For a hand problem, inspect whether the reference keeps the fingers visible and whether the photo includes the relevant arm. If the source information is weak, fix the input before making the prompt increasingly detailed.

A simpler replacement brief for comparison

Use a reduced scene description when the original brief asks for several actions at once. Keep the same photo and reference so you can evaluate whether the simpler language changes the relevant problem. This example has not been tested here.

One original adult performer follows the supplied gentle shoulder motion. Preserve the source face, hairstyle, and plain shirt. Keep the camera steady, the background simple, and the hands visible. No extra choreography, costume change, or new people.

Separate audio review from visual review

If a clip is silent, first inspect playback volume and whether the file contains an audio track. A muted preview and a silent media file are different observations. If timing looks wrong, compare the start of the motion against the start of the audio before changing the visual prompt.

Do not assume a motion-control result includes a particular song or voice. Audio behavior has not been verified on this site. Keep any original recording and the finished video separate until you know what was actually included and what you may publish.

Gather useful facts for a future support request

Record the service name, task identifier, time, selected mode, and the visible error message. Avoid sending passwords, payment details, or secret API credentials. A concise report with the failed stage is more useful than a statement that the whole video is broken.

For the current local workspace, explain what you selected and what the preview showed. A saved local brief has no provider task identifier. For a submitted motion transfer, use the task shown in My videos when asking support for help. Keeping that distinction clear prevents local browser behavior from being mistaken for a billed generation failure.
