Titolo: What program will convert a MPEG2 video to MPEG4 retaining a playback aspect ratio?

What program will convert mpeg2 or (ATI *.VCR) video to mpeg4 retaining
a playback aspect ratio? Dr.Divx and ATI MMC change a mpeg2 file
playback aspect ratio to video resolution aspect ratio when converting
to mpeg4. For example, Dr.Divx and ATI MMC change a 4x3 playback aspect
ratio of a 480X576 resolution video to a 480X576 playback aspect ratio.
What program allows to edit a mpeg2 or (ATI *.VCR) video retaining a
playback aspect ratio?

:

Linux transcode 
from man transcode;
      --export_asr C
           set export aspect ratio code C [as input]
           Valid codes for C are:
                1        1:1
                2        4:3
                3       16:9
                4     2.21:1
Linux ffmpeg
      -aspect aspect
           set aspect ratio (4:3, 16:9 or 1.3333, 1.7777)

Thanks for your reply.
Will Linux transcode retain, not change video resolution in pixels?
Will it work in windows?

I need a program for Windows.

If the source code for transcode is availible then you may be able to 
install Cygwin (UNIX for Windows) and compile transcode under Cygwin.
Cygwin is free from:

I have Cygwin installed at home and work.

Is the source code for transcode available?
How to compile transcode under Cygwin?


  Those Linux fanatics can be so annoying sometimes.  Changing
OS is hardly an answer to your problem, seldom is.
  Most any Encoder will allow you to establish aspect ratio settings
including the playback bit.  I use the TMPGEnc Encoders 2.5 & 3.0,
but even most filter based encoders allow such settings.
  Linux has its place, but it has a long way to go before it is able to
compete in the general consumer PC market.

While we're waxing philosophical, all that has to happen for linux to 
explode in popularity is for game developers to start using opengl or

True enough, but the fact remains that, in the hands of a skiled user,
Linux is far more powerful than Windows.

How to compile transcode under Cygwin?
Possibly, but much easier to install Linux in a partition and use the other
million or so free programs too.

Will it work in windows?
Nope

Linux is no language.
It is an operating systenm, partly written in C and guess what, partly in
assembler.
So you get a clue.

You have no clue, *I* use a PC to solve a problem.
Linux has the solution to this specific problem.
If you want to have a relationship wint MS soft, more then a solution to

In the hands of a sufficiently 'skilled' president the lives of many are irrelevant.

 Quicktime.
Funny thing.  I am building a streaming MPEG-4 encoder at work and Quicktime
doesn't obey the pixel aspect value when RTP/RTSP streaming.  OTOH Videolan
Client does.  I know that's not relevant to this discussion but it struck me
as funny if it handles it properly in file conversions.

First of all let me apologize for my typographical error.  I meant to
type "skilled."  It seems like you understood pretty well, though!
Good effort.  Excellent pattern recognition skills.
President?  Non-sequitor.  Whatever.  There is a windows program which
will do what is required.  Many, in fact.  I suggest you use them
instead.

Will Linux transcode retain, not change video resolution in pixels "if
I go" from MPEG2 to MPEG4?

Will TMPGEnc Encoders 2.5 & 3.0 retain, not change playback aspect
ratio (for example 4x3) and video resolution (for example 480x576) when
converting MPEG2 to MPEG4?
Dr.Divx 1.0.6 can retain playback aspect ratio (for example 4x3), but
changes video resolution, for example, 480x576 to 480x352(=4x3 playback
aspect ratio). ATI MMC retains video resolution but changes playback
aspect ratio from 4x3 to 480x576=5x6.

Why install bloatware on a perfectly good function PC?
I run:
a web server
A ftp server
record 4 TV programs at the same tiome from satellite,
play my mp3 automatically,
Have a newsreader open to type this
run an email server.
And client
Have high speed DLS
Control the house (temperatire, alarms).
Have remote controlled webcam (via webbrowser and telnet),
Have Netscape open in TABS on several sites at ones.
Have 2 audio mixers open for my 2 soundcards.
Run fvwm X windows manager
Have teletext display program running.
Just to pester you play a DivX AVI in one virtual screen in 720x576 PAL
So have 9 virtual screens,
Have 9 xterms open (terminals)
And WHAT exactly is that your windows box does NOW that was so useful?
You know, this MS guy, whatshisname bald or something, stated on CNN that
'no web experience shall happen without being exposed to a MS add'.
Sort of a last resort he! WHoaaaaaaa LOL he actually PAYS for that.

I go" from MPEG2 to MPEG4?
Normally, when you use transcode, you do not change resolution, in the sense
like h by v pixels.
The 'aspect ratio' is just a number in the AVI file that tells the player how
to resize (if needed) on your display.
I sort of am 90% sure you can change the aspect ratio field later, but I would
have to lookup the AVI spec.
Many players can change aspec,t in LINUX for example pressing key 'A" in xine
player will toggle you through many aspect ratios.

How to retain aspect ratio and video resolution when converting in
Windows?

 
Transcode is an excellent program, but I wouldn't suggest trying to 
install it in Windows.  Transcode has a boat load of dependencies and 
will not be a fun install.  On a side note, DVD::RIP is an amazing 
frontend for transcode.

 
Although that will help, the graphics cards manufacturers need to step 
it up and start releasing better Linux drivers as well.  nVidia does a 
good job, but ATI's Linux support is crap, especially if you're using Xorg.

I think you've misunderstood me.  I run Linux.  I was just saying that
there are windows applications that will accomplish his goals.

Great you run Linux, then you know, but REALLY are there those MS applications
that do that? Which one records 4 TV channels from sat at the time?
It would conflict with their DRM philosophy.
Their idea is 'pay for every thing you see every time you watch it'
the money goes into BG's pocket.
He pays some of it to the Republicans, they kill people in Iraq to put up the
oil price.
etc..

that some users prefer.
Note that I wrotye 'does' and 'NOW'
You did not really do that!
Boasting (about MS windows) is no good.
Show me how you record the 4 TV program AT THE SAME TIME NOW on your Microsof
box.
Here is how I do it :
http://panteltje.com/panteltje/dvd/
No I did not forget the 't'.
And as far as users go, if you have learned to always walk on your hands, then
sure, there are those that will prefer doing that.
But even for those, when exposed to so more freedom, will soon switch.
No 1 million commercials needed to 'convince' them.

High oil price is bad for Republicans and BG, because they buy oil much
more than develop. "They kill people in Iraq to" take Iraqi oil almost
for free!

This is a question of compatibility, because 99% of (for example)
Russians use Window, not Linux. I want to exchange information
successfully with other computers.

What does DVD::RIP do?

successfully with other computers.
Oh, but you could read what I wrote, and I could read what you wrote.
Linux users can also read word documents....
Windows users can read nothing BUT word documents it seems.

for free!
It does not explain the game.
Iraq was close to have the ban lifted on export.
That would have lowered oil prices worldwide.
Cheney and that other criminal have friends in the oil bussines.
GWB is a failed manager for some oil company.
Anytime YOU fill up your car, you pay for MS windows the second time around.
As simple as that.

 
DVD::RIP is a gui frontend for transcode; it's very fast and well 
implemented.  For a full list of features check out 
http://www.exit1.org/dvdrip/features.cipp
  The only hard component  to 
build is transcode, but if you can survive that dependency hell then 
DVD::RIP is a breeze.

"Ms Windows".
Why, I have it here, I was there from CP/M (you dunno what that is likely)
That YOU fail the brains to understand the wicked games the 'leaders' of the
world play, is no problem for me, but for YOU.
Actually I wrote 2 operating sytems, one with support for a windows GUI.
In assembler.
And BG (from MS) never got any further the an very feeble BASIC.
That is still more then you ever did but OK, before the next nuclear war you
still have a little time to catch up.
But then .. what use will it be... 
But anyways, when you fill up the moped, remember to thank GWB for the negative
discount.

Republicans do not want to buy oil at all, even for low price! They
want to take Iraqi oil by themself!

I want other users not to read only, but edit too.


Those who have no accomplishment whatsoever on any level write like you

English is a foreign language for me. I use it in the groups only. I do

You can not give an argument, you can only call names-this is a sign of
stupidity.
Have you been in Iraq? I was before the war. Now I can not go there,
because it is too dangerous and violent there. The only oil company
which takes Iraqi oil there now is the American Haliburton. And
Haliburton does not pay to Iraq anything for the oil at all!

Pity that your "oil-for-food" scam (really "oil-for-Saddam's-palaces") was
exposed, wasn't it?  Here's a nice hot cup of STFU for you.

TiVo was only available in the civilized world (US/UK).)
