Video ad analyzer
Upload an MP4 or MOV to see its length, aspect ratio, resolution, frame rate, estimated loudness, scene cuts, cuts in the first three seconds, and any on-screen text in the first three seconds.
How it works
Before an ad goes to review, check the basics a platform or a viewer will notice: shape, length, sound and how fast it moves.
- Length, ratio and resolution come from the file.
- Frame rate is measured while the video plays.
- Loudness is estimated in LUFS with the same weighting editors use.
- Scene cuts are found by comparing frames five times a second.
- Optionally, the text on screen in the first three seconds is read and checked against the Reels safe zone.
Everything runs in your browser. Nothing is uploaded. Files up to 200 MB.
Worked example
The 15 second sample video reports 15.0 s, 9:16, 360 x 640 and four scene cuts, one every three seconds.
Telehealth notes
- Captions in the first three seconds help people who watch with the sound off.
- If a disclaimer is on screen, check it sits inside the safe zone.
Questions
What is LUFS?
A measure of how loud audio sounds over time. Editors use it to keep ads at a steady level.
Is my video uploaded?
No. It is analysed in your browser.
How many cuts should the first three seconds have?
There is no rule. Use the count to compare your best and worst ads.
