. . . . Can anyone explain how you best choose Movie settings . . .
The general recommendation is to use the same resolution and framerate as the source video eg if your source video is 1920 x 1080 25fps then choose the PAL HDTV 1080i 16:9 25fps option.
However if you are mixing video resolutions and/or framerates then I would choose the majority format.
. . . . the Selection Range Frame disappears before the range has been sized appropriately . . . .
I cannot replicate this
- If you do not want to capture full screen click the Configuration button you can then select the frame size you want to capture.
Personally I do not use MEP for screen capturing, I use Screencast-o-Matic
