A/B Testing Video Bitrate Calculator Examples
Worked examples show how video duration, bitrate changes, and expected views affect file size and total delivery data.
These examples use video-only average bitrate estimates and decimal data units. They illustrate how even a modest per-view size difference can become substantial as complete views increase.

How to Read Your Results
A per-video file size is the estimated video-only data for one complete playback.
Total delivery data scales directly with the number of complete views entered.
A positive saved-data result favors Variant B for data use; it is not a quality score.
The bitrate reduction percentage compares B with A, not with a platform or codec benchmark.
Use the output as a planning estimate and pair it with observed playback and quality metrics.
Assumptions & Important Notes
- Every expected view is treated as one full playback.
- Both variants have the same duration.
- Results use decimal MB and GB.
- Audio and streaming overhead are excluded.

Frequently Asked Questions
Why can a short video have a large total delivery difference?
A short video may be small per view, but a high number of complete views multiplies that difference.
Which input has the biggest effect on total delivery?
Expected complete views, duration, and bitrate difference all scale the total linearly.
Can I use these examples for adaptive bitrate streaming?
They are useful as a simplified single-bitrate estimate, but actual adaptive delivery depends on rendition selection and viewing behavior.
Should I round the expected number of views?
Use the best available forecast. The result changes proportionally with the view count.
