hi, in CQMatic if I enter the avg. bitrate but leave movie time blank then a message pops up saying "please check movie time and/or avg" - does it need the movie time?

yes friendal,
the "time" is one parameter needed
to calculed the desired CQ.

Movie time must be at least "1".
Zero "0" or nothing, will give you an error.

If you choose a different time that is not the actual video time, CQ calculations will be off

hey friendal,
why don't use the movie time ??

is really important for prediction and i'm having doubts with the movie time here:

I wasn't sure if the movie time was necessary- just the avg bitrate. I put the movie time into CalcuMatic but that would be nice if it could pass that parameter over to CQMatic so I don't have to enter it twice
