# Video input

Video input means an uploaded video contributes model context. Frame, audio, transcript, timing, and format behavior are recorded as qualifiers only when documented.

- Markdown: https://canmyagentuse.com/features/video-input.md

Terminology basis: **Common product term** — https://docs.x.ai/grok/faq.

## Current support at a glance

Video input: 4 supported, 1 partial, 0 unsupported, 26 unreviewed across 31 cataloged products.

- Reviewed current products: 5 of 31
- Supported: 4
- Partial: 1
- Unsupported: 0
- Unreviewed: 26
- Not applicable: 0

Unknown or unreviewed means insufficient published evidence; it does not mean unsupported.

This row asks whether an uploaded or selected video contributes content to the model. Evidence should record whether the product uses sampled frames, native temporal input, extracted audio, a generated transcript, metadata, or some combination when that behavior is documented.

Record accepted containers and codecs, maximum bytes and duration, frame or sampling policy, audio handling, timecode awareness, resolution changes, model and plan restrictions, processing latency, and whether links are supported in addition to local uploads. A harness that accepts a video only for storage, sharing, or an unrelated editing tool remains unsupported for this row.

  - Target: hosted-observation — 2026-08-28 Grok Bot desktop documentation observation; observed 2026-08-28
  - Environment: hosted-default
  - Constraint (runtime): video is accepted up to 200 MB, but frame, audio, transcript, timing, metadata, and sampling semantics are not documented on the reviewed page
  - Evidence: [xAI — Grok Bot files and results](https://docs.x.ai/grok-bot/files-and-results) — documented; observed 2026-08-28
  - Qualification note 2: Evidence checked 2026-08-28: Grok Bot lists video among common supported inputs and documents a 200 MB per-video limit, but it does not describe which frames, audio, transcript, timing, or metadata reach the model.

### Perplexity (web)

- current: **Partial**
  - Target: hosted-observation — 2026-08-28 Perplexity web documentation observation; observed 2026-08-28
  - Environment: hosted-default
  - Constraint (runtime): MP4, MPEG, MOV, AVI, FLV, MPG, WebM, WMV, and 3GPP uploads are accepted and spoken content is automatically transcribed
  - Constraint (runtime): visual scenes in video are explicitly not indexed or searchable, so this does not establish frame-based or temporal visual understanding
  - Constraint (runtime): the general file-upload page documents a 40 MB per-file limit
  - Evidence: [Perplexity Help Center — File uploads](https://www.perplexity.ai/help-center/en/articles/10354807-file-uploads) — documented; observed 2026-08-28
  - Qualification note 4: Evidence checked 2026-08-28: Perplexity web accepts common video containers and automatically transcribes spoken content, but its documentation explicitly says visual scenes in video are not indexed or searchable. This is transcript-oriented input rather than documented visual-video understanding.
