    Hello all,
    Could someone please post a avisynth script to do the following

    Seperate interlace fields and resize and re-asssemble to playback twice the frame rate..

    eg: source - 5 minutes 25fps (50fps) 1024x576 interlace. A & B fields are seperated, 512x288 then resized to 1024x576 and joined to progressively to be played back at 100fps for 5 minutes

    thanks guys will check in the morning to see what you have come up with

    CHEERS

  2. Why do you want to convert 25fps interlaced to 100fps progressive?

    Here's 25fps->50fps for the same resolution, already twice the framerate:

    LeakKernelBob(Order=1)#if TFF, Order=0 if BFF

    Here's 25fps->100fps for the same resolution:

    LeakKernelBob(Order=1)#ifTFF
    SelectEvery(2,0,0,1,1)

    Load the LeakKernelDeint.dll and you're set.

    If this is a movie, I might question it being interlaced in the first place. Wanna post a clip somewhere? If it's something like a sporting event, then I can understand. But 25 frames per second is the same as 50 fields per second which, when bobbed, becomes 50 frames a second. That's all the movement/motion there is in the video. I don't understand why you're asking for 100 frames per second.

    A & B fields are seperated, 512x288

    If it's 1024x576 originally, when the fields are separated it becomes 1024x288.

    Well there are two reasons for me wanting to do this. I have alot of high motion video and the de-interlace "blend" doesnt look too good but when i deinterlace and discard second field it looks heaps better. Your right it only cuts the hieght by half, thats my typo...

    Second reason is that with a script like that i can control super slowmotion as "progressive" comes out twice as smooth when stretched twice as long (5 minutes to 10 minutes) each field side by side intead of interlaced

    Thanks for the reply

  4. Hi-

    OK, so if slowing it down by a factor of 2, add an AssumeFPS(50) to the end of that 100fps script, or AssumeFPS(25) to the 50fps script. To slow it by a factor of 4, add AssumeFPS(25) to the 100fps script.

    Thanks for the explanation. Makes sense now. I'm just a nosey SOB.
