make and save fast motion clips

[Lief]

I am a newby here. TIA for the help.
I am making clips of .MOV files from my Contour and I will put them together to make a short movie.
I have converted them to mpg (but I still have the originals)
I want some of the clips to be fast motion so I can have regular speed parts and fast parts included in the same movie.
I have NTI Home Movie Maker so I can put clips together but I do not know how to make and save the fast motion clips.

I read a post about scripting in some software and feel that is a little above me right now.
Is there software I can use to make and save the fast clips?

I have Aimersoft Video Converter Ultimate, VideoReDo (v3) and the above mentioned NTI.
I am using Windows 7 Home prem.

Easy ways i can think of is to use VirtualDubMod.
Learning to script a little using avisynth will go a long way in a project of this type.

Thanks Dragonkeeper, I downloaded the tool, the scripter and the script editor.

Can you post a sample of the code necessary to speed up and save a video clip?
I am using mpg for the clips.

Easiest method would be to use VirtualDubMod if you don't have a lossless codec install please do so (Huffyuv or Lagarith ). Load the mpg file into VirtualDubMod. Load your clip you wish to speed up into VirtualDubMod, click streams > stream list. Click on the audio stream and click disable and click "OK" (VirtualDubMod will not alter the audio stream so we disable it.)

Click Video > Frame Rate, click the second radio dial it should read "Change to____ Frames Per Second" set you desired frame rate here. Under " Frame Rate Conversion" select "Convert to FPS" and enter the frame rate of the original video file ( most often 29.970 or 23.976 in NTSC land) click "OK". Select "Video" > "Compression" select the lossless codec you have installed and click "OK". Click "File" > "Save As" enter your name and in a few seconds you should have your speed up file.

You can now use movie maker to encode the avi to mpg.


If you wish to retain the audio and have the auduio speed up as well you will need to use avisynth.

You will need to create a text file similar to the following.


DirectShowSource("path yo your mpg clip") # Frameserves your mpeg clip int desired app.
AssumFPS(50,1, True) #Changes video frame rate and speeds up the audio to match
SSRC (48000) # Changes sample rate of audio to match that of the DVD standard.

Save the file with an avs extension. Load the file into VirtualDub set the compression methods for your video and audio streams and save as avi.

Please note that using mpegsource to load a mpeg clip may be a better option, here is a link that describes its use "http://neuron2.net/dgmpgdec/QuickStart.html" I actual prefer to use mpegsource, but using directshowsource is a simpler approach.

Dragonkeeper, thank you for the excellent hand up to get this done.
