Please help with x264.exe command line for Full HD video

[Bencuri]

I would like to render my recent project in X264. I would like to keep original properties of the files, so similar quality, frame size, etc. Could you help creating an optimal command line for it? My computer is not extremely powerful, has i5-3210M with Intel HD4000 GPU.

I have attached a sample from the source.

The file details from Mediainfo:

Please be aware of that though Mediainfo detects the video as Interlaced 50i, in fact it is Progressive 25p!!!

Use MKVtoolnix to create an MKV form your .ts file

Create a simple avs script like this:

lwlibavvideosource("C:\pathto\sample.mkv")
assumefps(25)

Open a cmd prompt and run x264 like this:

"c:\pathto\x264.exe" --preset "faster" --crf 20 --output "c:\pathto\new.mkv" "c:\pathto\input_avs"

Or use a GUI like Virtualdub2
