How to detect black frames in a video?
on Nov 11, 2013 at 5:45:10 pm

Hello,

i have an edited video with several hour lenght.
In this videos there are 2-3 black frames but i don´t know where.

Is there a script or plug-in that can detect the black frames.

I tried Magnum-Edit-Detector and the Blackmagic Resolve Scene detection.
But only regular scene detection. Black frames are not detected.

Thank you!

A scene detector should find black flash frames. Run the scene detection, then look for single-frame events.

Did you tried that or do you assume?

In my case it didn´t work with Davinci Resolve Scene Detection.

Actually the black frame is not a scene change. Because the scene continuous after the black frame.

Isn´t there a script that only detect if a frame is black like rgb value 0,0,0 and sets a marker at this frame?
Unfortunately i can´t code that.
