GOP, B Frames and Codec Threads - What Do They Mean?

@NickW

so the higher GOP setting produces a smaller video file.

A few weeks ago I ran some tests; I found three things that could decrease the file size dramatically:

• Decreasing the Frame Rate
• Decreasing the Quality
• Increasing the GOP size

Of the three, increasing the GOP size had the least impact on the quality of the output video.

an opportunity to run some tests I had been meaning to run.
