AVI Synth/AVS Script Problems..

[Parypv]

Hey i've been wanting to convert an mp4 file (with x264 video) and (ac3 audio)
to xvid avi
the quality of the mp4 is amazing but my divx player doesn't support it ..unfortunately.
so i made a post about this a while back and was told to get mp4ui SUPER alltoavi and some more.
here is a link to the previous post i made -
https://forum.videohelp.com/viewtopic.php?t=306015&highlight=

this is the info from the previous post and for my mp4's (sample and main file was the same so no difference in which one i got the info from..)

here are the logs for the sample.mp4's when loaded into mp4box YAMB, mp4cam2avi program...
START-
* Movie Info *

END-

i couldn't get these programs to work and they took long to convert even my sample mp4's (for whichever program managed to do that)
i then made a post elsewhere at another site and was told to generate an avs script like this..

DirectShowSource("<full-path-to-mp4-file>")
LanczosResize(resultion)

is resultion right - supposed to be resolution? - not sure..

I have done this and have tried to open with virtual dubmod
when i open it - i get an error (script error line 1, column xx etc.)
any ideas how i can get this to work?
i really need to convert these to xvid avi - i'd love to use AutoGK since i've really got the hang of that now and the quality of some rips i made with a guide from here have come out very nicely.

Thanks guys.

Have you tried reading the avisynth help at the avisynth site - it explains all this and lots more. It is your best reference if you want to use avisynth.

[Parypv]

I've just had a look on the site but i can't see anything about AutoGK or x264 (MP4)
I've seen DVD to x264
But i'm looking for x264 (*.mp4) to XviD(*.avi)

Many thanks
I've got a lot of these files and i managed to do a task like this (though dvd to xvid) great quality with subs in a short amount of time. leave the job in queue and away it goes...all night

That's what i'd like to do with AutoGK and this sutuation - i've been told that it's possible to open the avs script with autoGK but can't figure out how..

Thanks guys and sorry for being fussy but these mp4's are driving me crazy - if only they were encoded in XviD video or DivX at that..

[guns1inger]

Start by looking at your script. Apart from incorrectly spelling Resolution, you are supposed to put the actual resolution there, not the word. Get your script right, then worry about loading it into AutoGK.

Hi-

Although there are add-ons to AutoGK that allow you to pause before encoding to edit the AVS, since AutoGK doesn't accept MP4 input, neither those add-ons nor AutoGK will be of much use to you.

[Parypv]

Hey thanks for the replies guys
Sorry about the imistake - i also thought that would be "resolution" but it was given to me by someone else who must have mispelt it - though i thought it was a typo i thought that since i'm new at this thing it might mean something totally different.

I've come up with a new avs script with help from you guys and others at another site.
Here is what I have..

directshowsource""
LanczosResize(640,480)


full path to mp4 file goes right between the ""
no (, no <,
do i need a space after directoshowsource? and then the "
also i was given the script by someone else and told what to do/use..
it says resize - i just want to convert it to XviD - preferably a direct rip but just a change in video codec - does that mean i need to resize?

I've read that avi synth basically makes the notepad seem like an avi file
is it possible for me to make the avs script (just locating my mp4) and then opening with virtual dubmod or another prog, and then usnig "save as AVI" or encode using XviD MPEG-4 Codec?
or is that much harder than it sounds..?


as i've said the quality as it is a x264 video is really good, that's why 'i'm looking to keeping the quality - or more likely losing a little but keeping a lot of the goodness =)
it's a shame that i have to convert it and not use the originals ...

Thanks guys

DirectShowSource("drive:/pathtofile/filename.extension")
Lanczos4Resize(640,480)

Where

Drive is the hard drive you have the video on
pathtofile is the full path to the folder your file is on
filename is the name of the file
extension is the file type eg. .avi, .mp4 etc.

Two minutes of searching and reading at the avisynth would have given you this. If that is too hard, then avisynth is way beyond you, sorry to say.

[Parypv]

DirectShowSource("drive:/pathtofile/filename.extension")
Lanczos4Resize(640,480)

.

sorry about that
forgot to put in the brackets ()
everything else was good
trying it out now
Thanks GunSlinger

EDIT - THANKS FOR THE HELP! - the vid is playing in virtualdubmod
now i need to convert to xvid with little quality loss if possible. i know how to do basic convert - but not wihth all the settings to get me a good output.
Sorry for being a pain guys but if i get this "guide" i'm set for a couple of weeks converting..

Thanks

Parypv

second edit - i just did my noob conversion on my sample file - out put is pretty good but i'll try the whole file to see if it stays in sync etc
Thanks for the help GunSlinger - but is there a better way of compressing to XviD? - how many passes is recommended for the best output - i've read that more than 2 is pointless..

[guns1inger]

What do you want to do ? If you want the output to fit in a certain size, do a 2 pass encode. If size isn't an issue, set the quality to high and take what you get.

You do have another alternative, which is to output to lossless compression (huffyuv or lagarith, for example), then you can use autoGK to do the final compression.

[Parypv]

Hey
The length is 1hr30mins max sometimes 1hr 10mins - i wouldn't mind having 7,8 maybe 850mb per episode - preferably 750megs
Vdub is telling me that my output will now be 1300~mb
i might cancel the job now since this will prob be the output - well something near to this and that's a bit too big for me.
i've cancelled and checked the quality out..it's really good =)
nice suggestion with the two pass - i've just checked two pass and it automatically suggests the best size?!
i also get the optinos i was looking for earlier - FPS , audio

Many thanks again for the help GunSlinger - i'm making good progress

Parypv

edit- run into al ittle trouble - i've selected 1,024,000 = 1gb exactly right? for my output
and i've selected vbr-mp3-128kbps audio
25fps
i click ok etc..
when i start the project my projected output becomes 4000mb+ and rises constantly lowers a bit etc..
is this normal -last time i done this it hovered around my projected file size and stabilised near the end.
shouldn't it be hovering around 1000MB? - unless i did a little but huge mistake..
i also have two target sizes one (on the main window under where i select how many passes which is now 937000~) and then another when i press "calc" which is what i typed in for 1,024,000 and the bitrate inc.,dec, in response to the input size.
Where do i type my final projected output ? or is it that that was for my video and now my audio will be on top of that ? :S
Thanks

[guns1inger]

It may be the VBR mp3 throwing it's calculations out. I don't know that I can offer much more help though. Hopefully someone better versed in Xvid encoding will drop by.

I'll wait a while then
Many thanks GunS1inger for helping me out with the AVS - maybe a new thread for the next step - encoding to XviD!..or keep this open for a little while
now i need to find a way of adding a job list to virtual dub.
i've been using virtual dub - should i try virtualdubMOD - or nandub?
what's the difference? - i know nandub splits avi's - prob more too =)

Thanks

Have a look at this guide, specifically from step 5 onwards

https://forum.videohelp.com/viewtopic.php?t=221896

It might help

[Parypv]

That's a nice guide but unfortunately that deals with separate audio and conversion for movies - i have loads of these files and i don't think that's the right method to go.
I'll wait until an XviD encoder drops by as you said =)

Thanks GunS1inger

I'm not going to leave it on because at 25% my output is 900meg
which means by the time it is finished it will be the 4gig that it estimated to be..
it starts off estimating my projected size but then jumps and goes crazyto 4-5 gig
what can be causing this?
it's two pass encode with XviD - VBR MP3 - 25fps..!

Thanks
