59.94 TS to 23.97(or 25.00) mkv

[polishchaser1]

Hi guys.
I have some movie in hd ts(720p) format but unfortunatelly it has 59.94 frame rate and i wish to change fps to 23.97(or 25.00 if possible) and convert into mkv format. I've been looking on this forum similar threads but I coluldn't find the same topic, because actually every similar topic says about converting ts to avi or dvd format. Now I really don't know which tool I should use to do this. After reading a lots of topics I downloaded avisynth actual version , mencoder, AutoMKV090, ProjectX(2006.03.30 version), mkv toolnix, DGIndex and have no idea which of them to use. Maybe the easiest way is writing some script for avisynth and using it with mkv toolnix or automkv. I really dont know.
I found some maybe useful script here:"https://forum.videohelp.com/topic339678.html" but there's no anything in it about changing audio fps.
Anyway projectx says that video is progressive and sound is in dts(3 audio tracks).
Can anybody help me please?

I found some maybe useful script here but there's no anything in it about changing audio fps.

If you're just removing duplicate frames, the video remains the same length, and the original audio can be used. Maybe it will be converted to MP3 audio, but you won't be changing its length.

You can often make it 23.976fps if the source is a movie. If not, 29.97fps may be the best you can do. You'll have to study your source to determine what you have. The best way to remove the dupe frames is with the use of an AviSynth script.

If you're really changing an NTSC source to 25fps, (why?), then not only will you be changing the video framerate and length, but the audio's as well. BeSweet has a preset to change 23.976fps to 25fps, but working with DTS audio presents its own set of challenges. I don't know anything about MKV, but the principle is the same as making an AVI as far as using an AviSynth script file to remove the duplicate frames before encoding.

My opinion is that if you've never done any encoding at all - and from the sound of your post you haven't - then this isn't a project with which you should begin your training. Walk before you run, as they say.

I was thinking about 25.00 fps because i want to add second audio track from dvd (which is in 25 fps) to converted movie, but i think I can just chanage audio fps to 23.976 or 29.97. My the biggest problem anyway is I'm not very familiar with avisynth and from what i know I should get some plugins for it to make that conversion. So if I'm not asking for too much could someone put here any helpful script pleeeeeease
The script till now I found is:

#for 720 progressive:
LoadPlugin("...\DGDecode.dll")
MPEG2Source("...\DGIndex_project.d2v")
SelectEven()#reduces 59.94 (or 50) to DVD framerate
LanczosResize(720,480)#if NTSC, 720x576 if PAL
#ConvertToYUY2()# enable if you use CCE

No plugins required. use ChangeFPS()

LoadPlugin("...\DGDecode.dll")
MPEG2Source("...\DGIndex_project.d2v")
ChangeFPS(23.976)
LanczosResize(720,480)#if NTSC, 720x576 if PAL
#ConvertToYUY2()# enable if you use CCE
