Choose clarity before style
A dramatic selfie is not always the most useful reference. A face partly hidden by hair, a microphone, or sunglasses gives a video model less information about features that need to move. Start with a sharp portrait in even light, with both eyes and the mouth visible. A relaxed expression is easier to reinterpret than a face caught mid-shout. The aim is a clear source, not a perfect beauty photograph.
This is a preparation guide for photo-to-video workflows. The exact formats, size limits, and upload options depend on the tool you use; consult its active controls before preparing a batch. Do not assume that a file accepted by one site will be accepted by another. If your chosen studio only offers text prompts, keep these portraits for a later image-supported stage rather than treating the prompt field as an upload control.
Match the crop to the performance
A close face crop suits a tight portrait but provides little information about shoulders, clothing, or hands. If the intended video shows an upper-body performance, select a source with visible shoulders and enough torso to establish posture. Leave room around the head. Cropping extremely close can force the generator to invent missing edges whenever the camera or performer moves.
For a solo performance, remove unrelated people from the reference. If you want a duo, use a workflow that explicitly supports multiple subjects and preserve a clear distinction between them. Similar camera height and lighting make two sources easier to combine visually. That is a practical starting point, not a guarantee of identity preservation. Compare the resulting faces at the beginning, middle, and end of the generated clip.
Prepare the file without inventing detail
Keep an untouched original and create a working copy for cropping. Make modest exposure adjustments if the face is too dark, but avoid aggressive sharpening or smoothing that alters skin and facial edges. Upscaling a tiny image can make its dimensions larger without recovering the missing information. If you have access to the person, taking a new photograph is often more useful than stacking enhancement filters on a poor source.
Inspect the exported file at ordinary viewing size and at a closer zoom. Look for blurred eyes, doubled edges, compression blocks around the mouth, and distracting background objects. Rotate the image correctly before uploading. Give the file a simple name so you can tell which version you used. Keep private information, documents, badges, and recognizable home addresses out of the background when they serve no creative purpose.
Use a small selection test
Compare two candidate portraits against the same short scene prompt. Do not change the camera and costume at the same time as the photo, because you will not know what improved the result. Select the reference that produces the more stable identity and plausible expression, even if the original still looks less stylish. Record why it won so you can choose future sources more quickly.
Use images you own or have permission to use, and make sure the person understands the planned synthetic performance. A publicly visible profile photograph is not the same as agreement to appear in a rap clip. Before posting, show the subject the final result rather than only the input image. If the performance changes their appearance or says something unexpected, choose another take or keep the project private. Clear consent belongs in the creative brief as much as lighting and framing.
Run a five-minute portrait check
Place the candidate image beside a blank frame matching the intended video shape. Imagine the performer turning slightly and raising a hand. Is there enough information about the shoulders and clothing to support that movement? Is the face still large enough to inspect? If the answer is no, choose a wider source or simplify the action rather than expecting a crop to supply missing detail.
Then compare the original with your prepared copy. Confirm that the crop did not remove hair, ears, or the edge of the chin and that exposure changes did not wash out the face. Ask the person whether the prepared reference still looks like them. Save the approved copy under a clear version name. This quick review catches avoidable input problems before they become paid generation experiments.
