Exactly what I was looking for

In my work I need to measure some things that happen far too quick for me to see. So I take slow motion video and try to eye ball it. At my last job I had a high speed camera for these measurements, that I don’t have anymore since changing jobs. With this app I’ve been able to get incredibly close to the measurements I’m after.
Hope you continue to keep this app up to date, it works great.
Features I still wish it had was a scrubber for video position so I can drag to the right point of the video. A play and pause button. And single frame advance and rewind.

Garbage, does not even open. A complete scam.

Don’t buy this, it won’t even open. Apparently a complete scam.
