  1. Hi there!

    Let's say I have the following video files:

    A: MP4, x264, 23.976 fps, 640x480
    B: WMV, WMV1, 25 fps, 854x480

    What I want to achieve is a merged video file like this:

    The numbers in brackets are the frames of the corresponding video files.

    The output file should be 640x480 in 25 fps. I usually use Spline16Resize to achieve my desired output resolution.

    Can someone explain to me how I can load multiple sources and merge them like above + getting the desired framerate?

    Thanks for any help!

  2. Depends on exactly how you want to change the frame rate. Something like this is simplest:

    A = LSMASHVideoSource("vid1.mp4").ChangeFPS(25) # or AssumeFPS(25, sync_audio=true)
    B = LWlibavVideoSource("vid2.wmv").Spline36Resize(640,480)

  3. Does B have pillar boxing ?

    You might want to adjust for the aspect ratio, if A is 4:3 , and B is 16:9
