MVTools & AVISynth script question with FFDShow

[Gnodab03]

Hi, I recently bought a new TV that runs at 60Hz that I have my computer hooked up to, and was looking into ways of raising the framerate of DVDrips I've done via Deinterlacing. in doing that, I ran across MVTools, which has a function called "MVFlowfps2." In the description of how to use it, it says

MVFlowFps2 (clip, clip "mvbw", clip "mvfw", clip "mvbw2", clip "mvfw2", int "num", int "den", int "mask", float "ml", clip "pelclip", int "idx", int "idx2")

It then goes on to describe what each of the switches does. My question, is what format am I supposed to write the script as? I've never done this before, so I'm a little confused. Do I just switch out whatever is in quotations with the values I want to use, and leave the template intact? I've tried that, and it appears that there is no change. Also, I'm using the AVISyth option in FFDShow Video.

For anyone more knowledgeable than I am, here is the site of the tool: http://avisynth.org.ru/mvtools/mvtools.html it's about a third of the way down. Thanks for the help

edit:

after using the template at the bottom of the page here:
# Assume progressive PAL 25 fps source. Lets try convert it to 50.
backward_vec = source.MVAnalyse(isb = true, truemotion=true, pel=2, idx=1, search=3)
# we use explicit idx for more fast processing and use full search
forward_vec = source.MVAnalyse(isb = false, truemotion=true, pel=2, idx=1, search=3)
cropped = source.crop(4,4,-4,-4) # by half of block size 8
backward_vec2 = cropped.MVAnalyse(isb = true, truemotion=true, pel=2, idx=2, search=3)
forward_vec2 = cropped.MVAnalyse(isb = false, truemotion=true, pel=2, idx=2, search=3)
source.MVFlowFps2(backward_vec,forward_vec,backwar d_vec2,forward_vec2,num=50,idx=1,idx2=2)

I get errors saying "source" isn't a command. So I change that to the file I'm playing, and that doesn't work either. any ideas?

edit 2: I'm not sure if this is relevant, but I'm using MPlayer classic, and have "add ffdshow video source" checked.

Add this above those particular commands


source=last

[Gnodab03]

Do I add that after every instance of source (i.e. change every source to source=last), or do I add that at the top of the commands?

nm. got it. thanks!

One more question. I have a video that is already in progressive format, so when doing the above, every other frame flashes nothing (black). Is there any way to change that? I tried looking through the switch definitions, and I'm stumped.

It should create interpolated "middle" frames. Dunno why it is doing that.

BTW, if your TV is 60hz, you should change your parameters in the last line of your script. It's creating 50fps files

Also, there's a newer version - MVtools2 with new scripts.


AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous filter, etc

super = MSuper(pel=2)
backward_vec = MAnalyse(super, isb = true)
forward_vec = MAnalyse(super, isb = false)
MFlowFps(super, backward_vec, forward_vec, num=60000, den=1001, ml=100) # get 59.94 fps

I should clarify: it was more to make the video run slightly smother than it was to have it run at 60fps. I'm not sure if that is the reason, but with the previous script, I could watch interpolated (sp?) video's at double the frame rate with no problem. with this script, I can't (the audio starts to lag behind the video). is there any way to reconcile the two, or am I stuck with not being able to watch smother video with the computer that I have?

To double fps with MFlowFps for fastest (almost) real-time playing:

AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous filter, etc
# assume progressive PAL 25 fps or NTSC Film 23.976 source
super = MSuper(pel=1,hpad=0,vpad=0,chroma=false)
backward_vec = MAnalyse(super, blksize=32, isb = true, chroma=false, searchparam=1,search=0)
forward_vec = MAnalyse(super, blksize=32, isb = false, chroma=false, searchparam=1,search=0)
MFlowFps(super, backward_vec, forward_vec, num=2*FramerateNumerator(last), \
den=FramerateDenominator(last), mask=0)

that one works perfectly! thanks for the help
