Avisynth: How do you Load an MPEG1 Clip?

rendalunit · #1 01-18-2003, 04:02 PM

i want to re-encode an mpeg1 video- how do i load it with Avisynth?

I tried DirectShowSource(clip) but I got an exception in TMPGEnc

thanks,
ren

Two options: either fast recompress as HuffYUV (which takes scads and scads of disc space) or use the MPEGDecoder plugin. I can't remember where I got it from, but if you do a search on Doom9 for posts by a guy called Nic you should find a link to his web site in his sig. I think

oh cool- I'll look for the MPEGDecoder plugin (Nic's the author of XviD right?). I can't load the mpeg1 into Vdub because I get an unexpected end of file error.

thanks,
ren

Well, I know he does his own builds of it. I think he's on the development team. Not sure

MPEGDecoder works great!! It created a .d2v file with my mpeg-1

I really like how you can load .vobs directly too with a script similar to this:

Code:

LoadPlugin("C:\encoding\MPEGDecoder.dll")
LoadPlugin("C:\encoding\FluxSmooth.dll")
LoadPlugin("C:\encoding\BlockBuster.dll")
LoadPlugin("C:\encoding\GripFit_preview.dll")
LoadPlugin("C:\encoding\LegalClip.dll")
LoadPlugin("C:\encoding\sampler.dll")

MPEGSource("D:\MOHICAN\VIDEO_TS\VTS_04.01.VOB+D:\MOHICAN\VIDEO_TS\VTS_04.02.VOB+D:\MOHICAN\VIDEO_TS\VTS_04.03.VOB+D:\MOHICAN\VIDEO_TS\VTS_04.04.VOB+D:\MOHICAN\VIDEO_TS\VTS_04.05.VOB+D:\MOHICAN\VIDEO_TS\VTS_04.06.VOB",0,"ff")
LegalClip()
FluxSmooth()
BlockBuster(method="noise",variance=0.5)
GripCrop(width=528,height=480,overscan=1)
GripSize()
GripBorders()
LegalClip()
Sampler(length=24)

so no need for DVD2AVI or FitCD

It looks very promising. I'm waiting for all the bugs to be ironed out first

How do you get the Inverse Telecine ( drop rff ) there

. If you read VOBs directly, the frame rate would be read as 29.97fps and not as 23.976, or am I wrong

hi Kwag,

The third parameter is "ff" - force film

this is from the readme

Quote:

MPEGSource("e:\rip\VTs_01_1.vob+e:\rip\VTs_01_2.vo b+e:\rip\VTs_01_3.vob)
Here the first thing that MPEGDecoder.dll will do is to check for a e:\rip\VTs_01_1.d2v file.
if a file with that name exists it will load that and assume that the d2v is for the three files.

if e:\rip\VTs_01_1.d2v does not exist, it will be created and then loaded automatically.

For D2V files created automatically by MPEGDecoder.dll it does not know if force film should be turned on.
If it should then put "ff" as the third parameter
i.e.
MPEGSource("e:\rip\big.vob", 0, "ff")

As for the second parameter- I don't have a clue what it's for.

It would be great if you could just do: MPEGSource("D:\MOHICAN\VIDEO_TS\*.VOB",0,"ff") and it would load all VOBs in ascending order

Edit: Better yet, just rip to a single VOB

Yeah I know!
It would be nice if you could write it like this;
SegmentedMPEGSource("clip.00.vob") and it would load the other vobs (clip.01.vob...so on)

just like you can do with SegmentedAviSource(clip)

I didn't think DVD Decrypter could do this, but now I see that it can
