Recreate a video

A reference video is flat pixels: nothing in it says how it was made. This use case measures it, fragment by fragment, and rebuilds it as a scene the user can edit, with their own content. The result reproduces what the viewer sees, not the original project.

Read picsart-video-rules first. One job: a reference video in, an editable scene that matches it out. Measuring and checking go as reference-fragment-matching says, with no SPEND gate; the SPENDs here are artwork or music you choose to generate.

Before acting on a stage, load the skills in its row that apply to this job, also when the work resumes there.

1. Take the reference in

ASK (with your host's own question tool, such as AskUserQuestion, so the options are buttons the user taps, the recommended one first; only where the host has none, the options numbered in one message; in unattended pace, never ask: write it to the project record's openDecisions with the answer you assumed, as picsart-video-rules says) for what is missing, in one question, with every file in one upload panel, as picsart-video-rules says (Asset URLs):

• the reference video;
• which part, when it is longer than the part they want: a start and end time;
• their own content for the places the reference shows photos, clips, logos or text. Without it, the scene gets plain stand-ins in each of those places: a colour box of the same size, and the text the reference shows. Never the reference's own pixels, as the reference-fragment-matching skill says;
• whether the reference is theirs: their own template, ad or video. It decides the sound (below) and where the decorations can come from (stage 1c).

The sound. When the reference is theirs, its soundtrack is the default: it is laid under the recreation from the hosted reference in stage 7. When it is not, the reference's music is someone else's: offer no sound, or a music bed made as the background-music skill says (a SPEND).

1b. Map the content to the reference's slots

Take stage 2's sheet of stills now and list the reference's content slots: each place it shows a photo, a clip, a logo or a block of text, in order. Match the user's content to them. When something does not fit, ASK (with your host's own question tool, such as AskUserQuestion, so the options are buttons the user taps, the recommended one first; only where the host has none, the options numbered in one message; in unattended pace, never ask: write it to the project record's openDecisions with the answer you assumed, as picsart-video-rules says) one question about it and recommend an answer:

• a different count: 4 clips for 3 photo slots, or 3 photos for 5 slots: which to drop, or which slot repeats;
• a still where the reference has video: hold the still, or give it a slow push;
• a different shape: a portrait photo in a landscape slot: crop to the slot, or fit inside it.

1c. Where the decorations come from

Decorations are what is not content: stickers, doodles, badges, shapes, frames. ASK (with your host's own question tool, such as AskUserQuestion, so the options are buttons the user taps, the recommended one first; only where the host has none, the options numbered in one message; in unattended pace, never ask: write it to the project record's openDecisions with the answer you assumed, as picsart-video-rules says) once, for all of them, with a recommendation:

• cut from the reference, recommended when the reference is theirs, as reference-fragment-matching says;
• redrawn as vectors from the stills: the only route when the reference is not theirs and nothing is generated;
• generated with picsart_generate on an image model: the only route that always charges, so it is a SPEND, quoted for every decoration at once as picsart-video-rules says.

2. Read it and check the scope

picsart_media_probe on the reference for its size, frame rate and duration, and a sheet of stills across it with picsart_media_video_stills. From the stills, decide whether it is within what reference-fragment-matching can rebuild. When it is not, say what of it can and cannot be rebuilt, and stop unless the user still wants it.

3. The fragment plan

Split the reference and take the global census as the reference-fragment-matching skill says. Then show the user the plan in plain words: the fragments in order, each with its window and what happens in it, and the elements that recur. ASK (with your host's own question tool, such as AskUserQuestion, so the options are buttons the user taps, the recommended one first; only where the host has none, the options numbered in one message; in unattended pace, never ask: write it to the project record's openDecisions with the answer you assumed, as picsart-video-rules says) once whether it is right. A fragment the user merges, splits or drops changes the plan before any measuring starts.

The plan is the project record. Where the host gives you files, keep it as recreation.md in the working folder, with the beat tables, the boundary records and every check; otherwise keep it in the conversation. Update it whole as each fragment lands.

4. Measure each fragment

The census and the measured beat table for each fragment, as reference-fragment-matching says, each kind of change on its own route there, with the tracking done as motion-tracking-from-video says. Start every job a fragment needs before following any.

5. Build each fragment

Build it as reference-fragment-matching and scene-building-basics say, from the beat table only. A beat with no measured row is not built: measure it first.

6. Check each fragment

Check it against the reference as reference-fragment-matching says, and check the scene as quality-review says. The fix rounds are picsart-video-rules's. A fragment that still misses after them goes on, and its gap goes into the plan in plain words ("the card docks 0.2 s late").

7. Join the fragments and lay the sound

Join them and check the whole clip as reference-fragment-matching says (references/seams.md there). Then lay the sound decided in stage 1. The reference's soundtrack goes on an audio layer, as scene-building-basics says, starting where the chosen part of the reference starts, so its cuts land where the reference's did, and check the cuts against its beats as the reference-fragment-matching skill says (references/seams.md there). A music bed is laid as the background-music skill says.

8. The user reviews

REVIEW the whole scene, as picsart-video-rules says. With it, in one or two sentences: what matches, and any gap the checks left, in plain words, never a score. Each change the user asks for goes back to the fragment it lives in, and through its check again.

9. Deliver

DELIVER as picsart-video-rules says.
