### 1/5 — DON’T BUY

*2023-02-05*

It’s not accurate at all, I put in the numbers and it ended with 26 GB, the actual video was 7 GB.

**Developer response:** Please tell me the settings of the video you want to calculate.

### 5/5 — DOMO ARIGATOO!

*2022-05-01*

Thanks very much for making this app so simple yet accurate. It is good to know how large video files will be as I switch between 4k DCI @ 100 or 200 mbps and FHD slo-mo at 200 mbps. (I know to add “000” to the amout in the “kbps” field, though maybe that ought to be measured in mbps?) The “4k” field already shows the DCI dimensions, and I appreciate the lack of clutter that a scrolling menu of frame sizes - not to mention of codecs and so forth - would impose.

### 5/5 — Works now well

*2021-06-15*

A bit tricky for the first use, but works now well. Need to press twice to select frame rate..

**Developer response:** Thank you.
You can select “Custom” and enter the frame rate in the text field.
