When and Why to Use
Use this to present a video stimulus, optionally with a live dial for feedback. It's best for:
- Ad or creative testing
- Comprehension and recall studies
- Real-time sentiment capture via dial testing
Videos are DRM-protected to prevent copying or screen recording. Secure videos are watermarked for traceability, and video links are short-lived, expiring shortly after they are issued.
Other Names and Formats
With the live dial enabled, this instrument supports dial testing, moment-to-moment rating, a video sentiment question, or continuous response measurement while respondents watch a video stimulus. The dial captures reactions throughout playback; without the dial, the instrument presents the secure video for subsequent questions.
Chat Experience
- Video fills most of the screen with start and end messages above and below
- If dial is enabled, it appears beneath or to the side depending on configuration
Traditional Experience
- Video plays fullscreen or centered
- Dial, if used, appears on the right or bottom with live interaction enabled
- Remote or keyboard users can operate playback and dial

Dial Testing
Set dial="right" to show the dial on the right of the video or dial="bottom" to show it below; with the default dial="none" no dial is shown. The dial defaults to a 0-100 range with the captions "Dislike", "Neutral", and "Like" — customize it with dial_labels and dial_caption. The video and dial are always displayed in full screen, if available.
