# VCR vs ThruPlay Rate

Video Completion Rate (VCR) and ThruPlay Rate both measure how much of a video people watch, but they use different completion thresholds and platform conventions. VCR typically means completed views divided by starts or impressions. ThruPlay is Meta's billing/optimization metric: 15 seconds watched or full completion on shorter assets.

**VCR** vs **ThruPlay Rate**

## Key differences

| Aspect | VCR | ThruPlay Rate |
| --- | --- | --- |
| Completion threshold | 100% of video length (or platform-defined "completed view") | 15 seconds watched OR full completion if video is under 15 seconds |
| Denominator | Often video plays/starts; sometimes impressions (verify source) | Total video plays (≈ impressions on Meta autoplay) |
| Platform tie-in | Cross-platform analyst metric; common in YouTube/TikTok reporting | Native Meta metric tied to optimization and billing events |
| Diagnostic role | End-to-end storytelling and CTA placement quality | Mid-funnel engagement suitable for ranking creative in Meta auctions |
| Sensitivity to length | Penalizes long videos — completion gets harder as runtime grows | Normalizes to 15s threshold — more comparable across mixed lengths |

## When to use VCR

- Evaluating whether viewers reach the end of longer explainer or demo videos
- Comparing completion across YouTube, TikTok, or cross-platform reports
- Diagnosing CTA/end-card performance on 30–60 second assets
- Reporting creative narrative quality to stakeholders who think in "completion"

## When to use ThruPlay Rate

- Optimizing Meta campaigns toward ThruPlay or cost per ThruPlay
- Benchmarking against Meta/TikTok engagement norms in ads managers
- Ranking creative when videos vary in length but share a 15s value prop
- Pairing with hold rate to separate hook vs body issues

## Examples

### Strong ThruPlay, weak VCR

ThruPlay rate is 24% but VCR is 6% on a 45-second ad. Many viewers cross the 15-second bar (strong mid-section) but drop before the end card — shorten the close or move CTA earlier.

### Weak ThruPlay, strong VCR on short asset

On a 12-second video, ThruPlay and completion converge. If both are weak, the hook fails immediately; if VCR is strong but ThruPlay is weak on a longer cut, check whether the asset exceeds 15s without delivering the payoff early.

## Common mistakes

- Treating VCR and ThruPlay as interchangeable on Meta reporting
- Comparing VCR across wildly different video lengths without context
- Optimizing only for ThruPlay on long-form assets that need end-card completion
- Using impression-based VCR and impression-based ThruPlay without aligning definitions

## Frequently asked questions

### Which is higher: VCR or ThruPlay?

On videos longer than 15 seconds, ThruPlay rate (15s ÷ video plays) is often higher than full VCR because completion is a stricter bar than the ThruPlay threshold.

### Should I use VCR on Meta?

Use ThruPlay for platform optimization and benchmarking. Add VCR when you care specifically about end-of-video actions (coupon reveal, end-card click, product demo finish).

### How do Hold Rate and these metrics fit together?

Thumbstop → Hold Rate → ThruPlay/VCR is a common diagnostic chain. Hold Rate isolates retention after the hook; ThruPlay and VCR describe progressively stricter watch depth.
