A public Duet combines two videos in a split screen playing at the same time, allowing side-by-side reuse from another creator. The layout shows simultaneous playback and permitted reuse of a public source, not that the two people were together, know each other privately, or match each other's account. Treat each half as its own source video: note the visible handle, caption or on-screen text on that side, mark what is missing, and leave co-location or relationship statements unsupported.

Why one frame contains two sources
A Duet combines two videos in a split screen playing at the same time, allowing side-by-side reuse from another creator. The frame is a container for two separate artifacts, not a record of two people sharing a place or a moment. The simultaneous playback and permitted reuse explain why two videos appear together; they do not explain a shared scene. [TikTok: Duet format and attribution]
- Describe the split-screen layout before describing either side.
- Say "two source videos played side by side" rather than "these two together."
Split the screenshot before any text lookup
Before running an image or OCR lookup on a Duet screenshot, separate each half and record it as its own input. What sits on the left belongs to one source; what sits on the right belongs to another. Keep the halves labeled by position so a later note can always point back to the side it came from. Use OCR only to read visible text and layout; do not run similarity-based identification on people in either half.
- Save two crops with position labels, not one merged image.
- Use OCR to read visible text only; explicitly stop before any person-level identification.
What each half can and cannot support
Each half may show a visible handle, a caption, on-screen text, a background, or time-related text if the interface included one. Those visible items are observations about one source video. They do not prove who operates the account, where the recording was made, or whether the other person agreed to appear. A public creator can allow Everyone or mutually following Friends to Duet, so the mere existence of a visible Duet cannot establish a private relationship or co-location. Absence of a familiar handle on one side is also not a finding; it is a limit of that half.
| observation | limit | next step |
|---|---|---|
| A visible handle on one side | Shows attribution on that source video only | Quote it as that side's public attribution |
| Matching background or framing | Does not by itself show one shared place; the format does not establish co-location | Do not read it as co-location |
| Time-related text on one side | Meaning and scope unclear from one frame | Record it beside that half without generalization |
| No handle visible on one side | The source may be cropped, covered or absent | Record the gap and stop the identity question |
Use the original public attribution
Where a side carries a public handle or an original post reference, attribute that material to its visible original source rather than only to the Duet frame. The checked source does not establish which side is reused in a given screenshot, so name what each side visibly shows. If the original public attribution is not visible in the artifact, say so plainly and treat that side as unattributed. Do not fill the gap with a guess based on appearance, style or a similar username.
- Attribute each side to its own visible public source where one is shown.
- Write "attribution not visible in this artifact" when a side lacks a handle.
Leave relationship and co-location claims unsupported
A paired frame invites a story about two people, and that is exactly the inference to withhold. Nothing in the split-screen layout establishes that the two people met, dated, lived near each other, or appeared in the same recording session. Hold those statements as unsupported and keep them out of captions, summaries and replies. If a reader asks whether the two are together, the honest answer is that the public artifact does not say, and the simultaneous-playback reuse format explains why two videos appear side by side.
- Rewrite "they were together" as "both appear in a public Duet frame."
- Do not use one side's content to characterize the other person.
When the source is absent, private or ambiguous
If a side is missing, cropped past recognition, on a private account, mismatched with the other half, or simply unclear, record that exact limit and stop there. Do not seek private records, request access, or attempt to identify anyone by similarity. An ambiguous frame is a finished observation, not a puzzle to be forced open. Write the limit beside the observation and end the note rather than adding an inference that the artifact cannot carry.
- State the specific limit: absent, private, cropped or mismatched.
- Stop; do not contact strangers or attempt identification.
Keep one record instead of scattered notes
Use a single labeled record per half so observations, limits and the stopping decision stay together. Add only what the artifact visibly shows, and leave a cell blank rather than guessing. This is editorial note-keeping advice, not a feature of any app; it is the same separation applied above, condensed for reuse.
- Open one row per half, labeled left and right.
- Record the limit in the same row as the observation it qualifies.
A couple more questions
Does a Duet mean the two people were in the same place?
No. The split screen is a two-video format: two videos play side by side at the same time, allowing side-by-side reuse from another creator. Co-location is unsupported unless the artifact itself says otherwise.
Whose account should I name when citing a Duet screenshot?
Name each side's visible public attribution where one is shown, and note separately who posted the Duet. If an original source is not visible in the artifact, write that the attribution is missing rather than inferring it.
What if one half of the screenshot is cropped or unclear?
Record the precise limit on that half and stop. Do not seek private access, run similarity-based identification, or merge the two halves into one person; an ambiguous side is a documented gap, not an invitation to guess.
Can I run OCR on the whole Duet image at once?
You can, but separate the halves first so text from one side is not read as belonging to the other. Label OCR output by side, mark text near the boundary as ambiguous, and use OCR only to read visible text—not to identify anyone.
