i have a xvid avi file.

here is the gspot technical info:



so the techno-heads amongst you - please tell me what i have to do to convert this xvid avi to mpg / m2v so that i can author my own dvd.

specifically, i don't want to alter the aspect ratio.

gspot states its 720x524.
does this mean the avi itself has been wrongly encoded?

if so, how can i correct this?

what are the best tools for the job?

thanks.

VSO ConvertXToDVD -- seriously, nothing else.
It has quality that approaches MainConcept Encoder, so very nice.

The only issue is to not put more than 2 hours on a disc.
Less is better. The newer versions also have 2-pass encoding. (I use v3, but it looks fine on 1-pass VBR).

Encoded wrong? Maybe. What's the DAR (display aspect ratio) set to? 16:9 ?
Many people are bulls in a China shop, when it comes to smart video encoding. Being botched is likely. I come across a lot of retail media that's encoded craptastically. (I'm still angry about the indy flick made by John Schneider in 2007. Thanks for the rotten encode, Bo Duke! Unwatchable drivel. A monkey with a stick could have done better work.)

If the video is really an odd size aspect, you'll have to matte it in a standardize frame. That will take more effort. A mix of VirtualDub work, followed by an actual MPEG encoder.

actually the newer versions of the program even allow you to choose what type of resizers and such you want to use (ex: I can now pick the Lanzos resizer). If the pic size is odd, you can have ConvertX encode it to letterbox. This will let the program add the matte needed so it displays properly

Interesting.

I may need to look at recent versions, when I get time.

LS - the DAR, as shown in the jpg is 1.374, about 11:8.

using convertxtodvd, settings: never deinterlace, letterbox, lanczos, i converted the avi to a 720x480 ntsc mpg:



visually, it looks ok.

but technically, have i done the right thing?
as i don't want to worsen the end result more than i have to.

note: i went for NTSC, as the source had a 29.976 frame rate. so despite going from 720x574 down to 720x480, i thought this was the correct thing to do. let me know if it is or not! thanks.

You're picking the wrong settings.
I don't time to expand on this further right now. Maybe Tranzor can post more?

is using AVStoDVD, using HCenc and Lanczos a better option than ConvertXToDVD?

YES. Also make sure Henc is set for quality not speed. I could never get avs to actually work, however if you got it working for you then what you listed above should come out just fine (or as fine as the mp4 source will allow). Plus it is also a freeway to do what you need

ConvertX is not a terrible program, but it's main goal is speed not quality. However the plus to that program is you can throw in literally any sort of format and it would do a halfway decent job on it, but it is also not freeware

Use FAVC with Henc. will come out with the best quality. ConvertX is ugly as hell for converting. I got a guide and what you need to use FAVC and Henc for converting. PM Me if u want it

konfusion - will look into FAVC.

one question - does FAVC resize the video?

as you can see from the 1st post, the video is sized 720x574 running at 29.976.
so is it a NTSC or a PAL video?

so what will FAVC do to the video?

thanks.

favc does whatever you want it to do
but that gspot or whatever says 720x480 which is ntsc not pal

if pal would say 720x576 25 fps

what sizes would you possible need? there is only two options you would ever need with dvd pal and ntsc. 720x480 or 720x576 depending if you pick outpput pal or ntsc

konfusion - are you looking at post #7?

that is the wrong gpot to look at.
that was when i already converted the video using convertxtodvd.
and did it wrongly - according to LS.

i'm going back to my original video, for which gspot states its 720x524.
so is this NTSC or PAL?
