Help me write the encoding script

[Satoshi18]

I'm familiar only with handbrake , and I'm new to coding, scripting etc
Can anyone please help me how to make a great encode
I don't know any filters etc.
I opened AVSpmod and open'd a vob file which I want to encode

DirectShowSource("C:\Users\Admin\Desktop\VTS_02_1.VOB")

This is what I got, what to do next upto the encode is done? I'm new to everything.
I want to upscale it from 720x480 to 768 x 576. Suppose This is how.

LanczosResize(768, 576)

Want to encode it in Hi10p
Source is NTSC 29.970 FPS VOB which I need to decimate/IVTC i suppose, back to 23.976 fps, but not sure how to do that.


Encoding settings I want to use are the following: ref=16:trellis=2:subme=10 CRF=18

Can anyone please write a script for me and guide me through whole encoding process?
Thanks!

Best start with something like StaxRip, MeGui to get some basic understanding of how the whole thing works.
As a side note: Using DirectShowSource is usually a mistake.

That said, here's a simple Avisynth+ example which applies IVTC and resizes.

# for multi-threading 
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
## START - only needed if you use a portable Avisynth version
ClearAutoloadDirs()
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\LoadDll.dll")
LoadDLL("I:\Hybrid\32bit\avisynthPlugins\libfftw3f-3.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\DGDecodeNV.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\TIVTC.dll")
## END - only needed if you use a portable Avisynth version

# loading source: G:\TestClips&Co\files\interlaceAndTelecineSamples\telecine\apollo_440_-_lost_in_space(jason_nevis_lunar_landing).m2v
# color sampling YV12@8, matrix: bt709, scantyp: telecine, luminance scale: limited
DGSource(dgi="E:\Temp\m2v_edadb2b3022d17feece2e4645c57aa58_853323747.dgi",fieldop=2) # .dgi-file was created using DGIndexNV
# current resolution: 720x480

# deinterlacing/IVTC
TFM()
TDecimate()
AssumeFrameBased()

# additional filtering

# scaling to 768x576
Spline36Resize(768,576)

# adjusting bit depth current 8 to target 10

# convert to 10bit for encoder
ConvertBits(10)

# for muli-threading, 16 might be to high for your system
PreFetch(16)

# setting output fps to 23.976fps
AssumeFPS(24000,1001)
#  output: color sampling YV12@10, matrix: bt709, scantyp: progressive, luminance scale: limited
return last

The script used/generated by StaxRip, MeGui and similar GUIs should look similar.
Alternatively to DGDecNV+DGIndexNV one could also use MPEG2Source + DGIndex:

# for multi-threading 
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
## START - only needed if you use a portable Avisynth version
ClearAutoloadDirs()
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\LoadDll.dll")
LoadDLL("I:\Hybrid\32bit\avisynthPlugins\libfftw3f-3.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\DGDecode.dll")
LoadPlugin("I:\Hybrid\32bit\AVISYN~1\TIVTC.dll")
## END - only needed if you use a portable Avisynth version

# loading source: G:\TestClips&Co\files\interlaceAndTelecineSamples\telecine\apollo_440_-_lost_in_space(jason_nevis_lunar_landing).m2v
# color sampling YV12@8, matrix: bt709, scantyp: telecine, luminance scale: limited
MPEG2Source(d2v="E:\Temp\m2v_edadb2b3022d17feece2e4645c57aa58_853323747.d2v") # .d2v was created using DGIndex
# current resolution: 720x480

# deinterlacing/IVtC
TFM()
TDecimate()
AssumeFrameBased()

# additional filtering

# scaling to 768x576
Spline36Resize(768,576)

# adjusting bit depth current 8 to target 10
# convert to 10bit for encoder
ConvertBits(10)

# for muli-threading, 16 might be to high for your system
PreFetch(16)

# setting output fps to 23.976fps
AssumeFPS(24000,1001)
#  output: color sampling YV12@10, matrix: bt709, scantyp: progressive, luminance scale: limited
return last

Ps.: No, I'm not guiding anyone through any process, like I wrote best start small and use a GUI to start with.
