Change resolution of XVID??

[jarko]

Hello,

I have an Xvid file with the resolution of 560x240 and i would like to change it to 640x480 because i am trying to make it full screen on the tv. Can you tell me if the same method will work with other formats such as divx and avi.

Thanks for help.

Well, I've changed the resolution in TMPGEnc during the encoding process and I did not see any loss in quality. I do this with anime .avi files that are not 640 x 480. They are something like 512 x 380 or something of that nature. I imagine that if the source file is 120 x 90 or something low like that, that encoding it higher may be pixelated. I'm not sure as I have not done anything with a really small source file resolution.

Hi
Thx for your answer, but can someone explain to me step by step how to do this

I'm going to assume that you have encoded before in TMPGEnc...

-In the Advanced tab settings, double click Clip Frame at the bottom
-Arrange Setting tab, Arrange Method, set to Center [Custom Size] and I enter 640 x 436, click "OK." THAT SIZE WORKS FOR ME, I'VE TRIED 640 X 480 BUT IN MY OPINION IT DISTORTED THE ASPECT RATIO FOR ME--USE WHAT LOOKS GOOD TO YOU IN THE PREVIEW PANE.
-In the Advanced tab settings, uncheck Clip Frame at the bottom, Video Arrange Method should now be set to Center Custom Size and the size you entered is below it. YOU DO NOT NEED TO GO TO CLIP FRAME BELOW IN THE ABOVE STEP IF YOU DO NOT WANT TO SEE A PREVIEW, YOU CAN JUST ENTER THE SIZE IN THE ADVANCED TAB SETTINGS.

Hopefully all of your other settings work. For testing you should try the Source Range option in the Advanced Tab Settings and encode like 10 - 60 seconds of video just so you can play back the finished product to see if it looks good to you without spending a lot of time encoding the whole thing. That way you can just play back the video on the computer prior to burning DVD+-RW or coasters....

Sorry, that I'm still bothering you but what am I supposed to do to the encoded file?

on TMPGEnc's first screen you should have chosen to create either system or elementary outputs for eihter .mpg or .m2v and .mp2 files for creating files for authoring a DVD or some other kind of A/V media that you are going for.

wait a minute there, do you want to create a dvd to be played on your standalone dvd player, do you have a divx/xvid compatible player and want to keep the movie in that format or what? It depends on what you want to do with the file.

In any case making a widescreen (560/240=2.33) movie fullscreen (for 4:3 tv output) without inserting black bars at the top and bottom will result in a highly distorted picture! Not sure you would want that.

what do you want to make? vcd,svcd,dvd or just a new divx?

if you are playing it on a computer to the tv just use a software player that can zoom like Zoom Player.

First off 640 X 480 IS NOT any known TV RESOLUTION....it is a pc's (1:1 pixel) EQUIVALENT of a NTSC TV's resolution.........in other words an .avi (divx, xvid etc) file of 640 X 480 will look the SAME (aspect ratio wise) on a pc monitor as a 4:3 NTSC TV/mpeg2 picture of 704 X 480.

This is because a pc's pixels are square (1:1) and TV/mpeg2 pixels are un-square (0.91 : 1 NTSC / 1.091 : 1 PAL for 4:3... and... 1.21 : 1 NTSC / 1.45 : 1 PAL for 16:9 mpeg2 encoding) the playback of different TV ratio's is known as the DAR (derived aspect ratio) whilst the mathermaticaly derived height / width is known simply as AR (aspect ratio) and note .avi files only have an AR not a DAR.... so your 560 X 240 xvid is a file of 2.33 :1 AR.......which unfortunately for you will NOT fit on a 16:9 or a 4:3 TV without black bars unless you SEVERLY crop it or SEVERLY distort the picture.

To put it simply, a NTSC 4:3 'pixel' is a rectangle 9.1% taller than its width and a PAL 4:3 'pixel' is a rectangle 9.1% wider than its height whilst a pc pixel is not a rectangle but a square.

As Balrdick said if your playing the file thru a TV-out just use Zoomplayer to zoom and correct...........if your playing the xvid on a .avi enabled DVD player leave it alone the player should correct the difference (and have a zoom feature to fill the screen)....if your encoding to DVD you need to resize AND correct the difference AND crop it if you want full screen (note....DO NOT CROP IT...encode with bars).

Use FitCD for calculating avi>mpeg resolutions and install AVISynth to use the scripts generated by FitCD.......no calculations required!!!!!

I want to keep my movie files in Divx, Xivd format.

I want to keep the same formats
