You should take it out... unless you are compleatly sure there will be no interlaced frames. I tested both ivtc (this time with FieldDeinterlace())& decomb (with post=true & false) and found this out: 1. post=false... it does good job, but every n frames i get interlaced frame or 2. 2. post=true... same as before but the interlaced frame is gone. The frame is a little blury though. :(. Perhaps this can be fixed changing other options of Telecide() function... but I don't have time to experimet much. 3. ivtc removes this frame or (most likely) it does not decimate like decomb :confused: ??? before it was frame number 7033,but now it is 7032. oh... yes... the frame is correctly deinterlaced... :) Here is an example : picture is as follows: post=false,post=true,ivtc. hmmm... why is my attachment not seen? oh, well you'll have to trust me on that.
