Whats wrong with my Avisynth script?

[geordie10]

So basically my setups is as follows;
AMD Ryzen 7 1700x 8 core 16 threads
16GB Ram
Radeon RX550 Series
Windows 10 64 bit
Avisynth+ latest version as of yesterday and AVSPmod

My issue is I'm working on my script in AVSPMod and it previews fine in AVSMod. However, when I run the below CMD Prompt command, it loads for about 10 seconds then disappears. If I drag the .avs file into Virtualdub and try to save as an .avi there, it also crashes. Is there something wrong with my script or is there a better way for me to save to Huffyuv that what I am current doing?

Update: I have tried with my source as an .avi file and it seems to work now. So what would I change in order to edit a ripped .mpg from DVD?

Command prompt line (through.bat file)

ffmpeg -i "dbz.avs" -c:v prores -profile:v 3 -pix_fmt yuv422p10le -c:a pcm_s16le "dbzfinal.mov"

Avisynth Script

SetFilterMTMode("QTGMC", 2)
FFmpegSource2("dbz.raw.mpg", atrack=-1)
ConverttoYV12()

dbz.raw.mpg

Is the video actually raw (elementary stream)
If yes are you sure the extension is mpg and not m2v

The definitive way to work with DVD sources is to use DgIndex to build an index file (.d2v) from the VOB files, then Mpeg2Source() in an AviSynth script to open the index file. Commercial DVDs must be decrypted first, of course.

DGIndex will open his (decrypted) .mpg program stream as well.

Yes. But why bother remuxing from VOB to MPG if you don't need to? It's just an extra step where something can go wrong.

On rare occasions remuxing is necessary -- like when the VOB has multiplexed video streams. You need to use a tool like VOB2MPG that will pick out only one of the streams. The IFO files are needed for this because they specify how to pick out a single stream.

OP already has an MPG in hand and I'm letting him know that DGIndex will open it.
