KVCD: Change Framerate but retain Video speed?
 

Hi Guys.

I have a Divx with a weird Framerate (15.004fps).

I just wanted to ask, how to change the Framerate but not to increase the speed. You know, I dont want this so called "Chipmunk" effect.

Is there a way to manage this.

Yes. Let TMPGEnc convert the framerate for you. :)
Not sure how prediction would work though, and the film might be a bit jerky. :roll:

Thank you Pyromania, it works.

I also know how to make a accurate prediction.

Here is an example:

Let's say you have a Divx with 29,976 fps and you want to have a 25 fps KVCD.

Make this calculation :

OldFramerate/RequiredFramerate, in this example:

29,976/25 = 1,19904 = 1,2.

Then add the Line AsummeFPS(25, true) to your script and make your usual prediction with Tok. Let's say the predicted CQ is 80, then you have to make this calculation :

PredictedCQ*(Oldframerate/RequiredFramerate), in this example:

80*(29,976/25) = 80*1,19904 = 95,9232= 95,92

Now you have your Final CQ = 95,92
