aspect ratio conversion questions

August 5th, 2016

I have a small mystery, that could be just me not understanding how some file formats and programs work.
This is my puzzle….
I download and burn DVDs all the time but now and then, I get aspect ratio problems.
for example, today, I have downloaded a TV series that was titled as a DVD rip, the files are in AVI.
they play on the computer (windows media player, nero showtime or or other progs) in perfect wide screen.
I use convertxtodvd most of time, and what happens is, on automatic, SOMETIMES a 16:9 refuses to convert that way, and converts to 4:3.
Even if you set it manually to convert to 16:9, it wont.
Which is really strange because other rips and AVIs in 16:9 with almost the same file sizes, convert easy and burn on DVD in 16:9.
even stranger, the ones that WONT keep their original aspect ratio can USUALLY be burned in 16:9 with Nero, BUT…. only if you burn one or 2 “episodes” or “segments” (all of these in question are about 750MB AVIs) on one dvd.
but other stuff I download, that is 16:9, 700+MB per AVI segment, often I can use convertxtodvd and pack up to 8 of them on one DVD and they burn percectly, in wide screen like they are suppose to and in decent quality.
which really gets me scratching my head.
I’ll give you a real example… yesterday, I burned on one DVD, a TV series in widescreen 16:9. I got 7 one hour long, 700=MB avi’s on one dvd.
now today I am trying to do the same thing with a different tv series, and convert xto dvd refuses to keep the 16:aspect ratio on only FOUR 1 hour, 700mb+ AVI files, on one DVD.
I am ending up burning only 2 on a dvd and with nero, since convertxtodvd wont even do it with one file…. it wants to make it 4:3, so disk size is not an issue there…it has the space, since nero did it.
So there is maybe something I dont grasp about AVI to DVD conversion, or is this just normal freaky ~love~ you run into with converting to DVD?
That probably made no sense at all…. LOL
what kills me is the file size on all these are about the same…. 700-800MB AVI files, in 16:9 ratio.
sometimes ConvertXtoDVD will pack 6 or 7 of them on a standard 4.7GB DVD, with no problem at all.
then like today…. it refuses to convert even one of them right.
on a side note, if I leave convertxtodvd do what ti wants and go with 4:3, it will gladly pack 8 episodes on the dvd….
but I dont like 4:3 when the original AVI is in 16:9, it looks rotten with the edges cropped off.
does this have something to do with how the uploader ripped it, or something?
or is it a convertxtodvd problem?
(is there a program to recode the problematic AVIs to convert with no aspect problems?)
I dont mind having to split a 4 part series onto 2 dvds, but when i come onto a stubborn set of 10 or more series like that…. yeah I get p!ssed they wont pack 6 or 8 on a dvd like most everything else.
I know, packing stuff that tight lowers the viewing quality, but my eyes are getting old and my TV is small, so for me, a little quality loss doesnt bug me at all.
I’m one of the old school who is still all tripped out the TV is in color and not B&W….
LOL
any tips or suggestions on what either I dont understand here or what I can do about it, or just some helpful info on conversion in general as it applies to this problem I will greatly appreciate.

Answer #1
Firstly how do you know that your downloads are in 16:9 format?
Do you use Media Info or a similar tool to give you this information?
Filesize is not an indicator of which format ie 4:3 or 16:9
Which version of ConvertX to DVD are you using?
If you want to manually convert the AVI files you can use Virtual Dub with the RESIZE filter
Answer #2
when I drop the AVI into Convertxtodvd it tells me…
Input file type; AVI
aspect ratio: 1.8333 (16:9)
Auto size: widescreen (16:9)
video : MPEG4 704×384
version 2.2.3.258
the size of the file doesnt seem to be an issue for most other projects….
like I said, sometimes I can put up to 6 or 8 of the same file types with the same properties.
so I assume if the file properties are pretty much the same (file size and aspect ratio) then when the program refuses to convert the AVI to dvd and preserve the aspect, no mater how much room it has to do it on, then something is not right somewhere.
it doesnt happen all the time but enough to be an irritant.
its happened with older versions of conx2dvd too.
some peoples rip jobs just wont stay widescreen like they should…. and to get them to stay you have to burn only 2 to a dvd, and with nero since other progs wont do it either.
I
‘ really wondering if its the files problem and not the programs.
fortunately there is almost always a few different peoples uploads to pick from so, one of them usually works if the first download wont.
what “problems” would convertxtodvd come across that it just forces the aspect ratio to fullscreen on a widescreen AVI, when the files properties SAY its widescreen 16:9?
Answer #3
The problem I think could be that. widescreen or 16:9 is
720×576 pixels
As this is not being adhered to, your end result is that you end up with 4:3 being displayed
Answer #4
I think that you are trying to fit so much on a DVD that Convertxtodvd is being forced to compress so much that the aspect ratio is compromised…More than 2 hours playing time could possibly cause problems..
Answer #5

I’ll bet thats it.
cx2dvd cant resolve the conflict and just goes default fullscreen.
I’ll have to pay attention to the pixel x pixel size next time it works ok and next time it doesnt.
thanks!

thats happened too but in this instance, a one hour program all by itself on a DVD was not converting right… so disk space wasnt the issue.
one of the reasons I like Cx2DVD is because you can dump as much as you want on one disk and it will pack them on, and make them fit.
yes, pack to many and you get a bad bad picture…. if its a movie I dont do that, but for a tv show I just want to watch once, packing @7 +/- one hour program on a disk doesnt make it any worse than watching TV (quality).
once I get a bigger Tv, I’ll probably notice it more.
blanks are cheap, downloads are free.
life is good.
