Turn a bedroom video into a studio shoot

I have attached one frame from a talking-head video I filmed in a normal room. I want to restyle this frame so the finished clip reads as if it were shot on a real set, and then use it as the look reference for regenerating the video.

First, look at the frame properly and tell me what is actually giving away that this was filmed at home: the direction and quality of the light, the colour temperature, what is behind me and how far away it is, the depth of field, the camera height relative to my eyeline, and anything in the wardrobe or the background that a set designer would remove. Be specific and blunt, name the objects.

Then tell me which of those I can fix in an image edit without changing my face, and which ones would require reshooting. I want the honest split, not a list of everything you could theoretically change.

Do not write the restyle prompt yet. Just give me the diagnosis and the split.

Now write me the image-editing prompt for this frame. I am pasting it into an image model that edits an uploaded photo, so write it as a single instruction paragraph addressed to that model, not as advice to me.

Direct it like a cinematographer would. Specify: the key light (direction, height, hardness and colour temperature in kelvin), a fill and a practical light if the scene needs one, the background (what it is, how far behind me, and how out of focus it should read), the lens and aperture look you want the depth of field to imitate, the camera height and angle relative to my eyeline, and two or three set-dressing objects that suit the mood of [describe your content in one line].

Then add an explicit preservation clause at the end of the prompt: keep my face, hair, skin tone, body position, head angle, gaze direction and expression exactly as they are in the source image, keep the framing and crop identical, and change only the lighting, background and set. State that no elements should be added between me and the camera.

The mood I want is [warm and lived-in / clean and editorial / moody and cinematic]. Give me the prompt as one block I can copy, then three one-line variants that change only the lighting setup so I can generate all four and compare.

Now write the prompt for the video model. I am giving it two references: my original video clip, and the restyled still we just made. Write it as one instruction paragraph addressed to the video model.

The prompt must say clearly which reference governs what. The video reference governs motion, timing, camera movement, body position and performance, and none of that should change. The image reference governs the environment, lighting, colour grade and set, and the finished clip should look like the still moving. Say that explicitly, in that order, because ambiguity here is what causes drift.

Include an identity lock: the subject's face, hair, skin tone and wardrobe must match the image reference exactly for every frame, with no morphing, no changes in facial structure between frames, and no extra people or hands entering the shot.

Describe the scene in the restyled still in about twenty words so the model has a text anchor as well as a visual one, and specify the grade in plain terms, for example warm highlights with soft shadows and no crushed blacks.

Finish with a short negative list of what must not appear: text or watermarks, warped hands, changing background objects, flickering light, and any change to the camera move.

Here is a frame from the clip the video model produced, and here is the restyled still I gave it as the reference. Compare them and tell me exactly where the generation went wrong.

Go through it in this order: identity (did my face, hair or wardrobe change), motion (did the camera move or my body position change from the original), environment (did the background objects shift or the light change mid-clip), and artefacts (hands, edges, text, flicker).

For each problem you find, tell me whether the fix belongs in the image reference, the prompt wording, or the reference weighting, and give me the exact revised line to change. Do not rewrite the whole prompt, give me the specific edits so I can keep everything that already worked.
