Media & Transcriptions
This tab combines video playback with an interleaved markers/transcription timeline.
Recording view modes
When screenshare recordings are available, toggle between:
- Camera — camera recording only
- Screen — screenshare only
- Camera + Screen — camera primary, screenshare below
- Screen + Camera — screenshare primary, camera below
Markers & transcription timeline
The toolbar provides:
- System markers toggle — show/hide automatically generated markers
- Transcriptions toggle — show/hide transcription segments
- Source selector — choose between multiple AI transcription sources (when available)
- List / Timeline toggle — switch between flat list and time-proportional views
- Follow playback — auto-scroll to keep the playhead visible
- Add marker — place a new marker at the current playhead position
In Timeline view, use the mouse wheel to zoom in/out and the +/− buttons in the top-right corner.
Marker pairs following the Label_start / Label_stop naming convention are linked with a purple connector line in the timeline view.
Confidence scores
AI transcription segments that include confidence data display a colored background:
- Green — high confidence (80%+)
- Yellow — medium confidence (50-79%)
- Red — low confidence (below 50%)
The exact confidence percentage appears next to each segment in list view.
Manual transcription
Researchers can create a manual (user) transcription to correct or annotate AI output.
Creating a transcription: Click Add manual transcription in the toolbar. Three creation modes are available:
- Blank — start with an empty transcription
- Copy from source — duplicate all segments from an AI transcription
- Pick segments — cherry-pick specific segments from an AI source
Only one manual transcription is allowed per participation.
Editing: Click Edit transcription to open the editor panel (desktop only). The editor provides:
- Per-segment text editing via textarea
- Timestamp display with Set from playhead buttons (S for start, E for end)
- Split a segment at the current playhead position
- Merge a segment with the previous one
- Insert a new segment after the current one
- Delete a segment
- Undo / Redo (Ctrl+Z / Ctrl+Shift+Z), up to 50 steps
- Auto-save every 30 seconds while editing
- Unsaved changes indicator and manual save button
The editor auto-saves when you switch tabs or close the panel, so you won't lose work.

Analysis results
Each completed analysis (transcription, emotion, etc.) can be downloaded as a JSON file.
Media files
Camera and screenshare recordings can be downloaded as MP4 files.
Use Download All to download all data and media files at once.
Data Dictionary
The Data Dictionary gives you a quick overview of every marker name used in the session, without scanning the full markers table.
- User markers: names you added manually during review.
- System markers: names generated automatically by tasks.
Each marker includes a short English description to help standardize meaning across analyses.
Use consistent marker names across sessions to simplify coding and analysis, for example: instruction start, instruction end, block A start.
