For the technically-inclined audience, here’s a brief tutorial on how to start understanding characteristics of video recordings. This is also a sneak peak at some of the things we start with.
Let’s ingest a video file named webinar.mp4
Some of the basic characteristics we want to look at are:
Just a few lines of code provides you the answers. We use a combination of different tools. You can use something like Matlab (the functions below will work in ML).
- B = v.BitsPerPixel;
- F = v.FrameRate;
- D = v.Duration;
- Format = v.VideoFormat;
Here are the answers:
- B = 24
- F = 30
- D = 4.7
- Format = RGB24
With just 4 lines of code we now have some elementary characteristics of this webinar clip.
So our test video has 30 frames/second and it’s using 24 bits per pixel. That’s pretty standard as most videos are 30/60 fps.
24 bits per pixel should provide enough vividness for most casual viewing scenarios.
