what software to use to convert HDTV source to low resolution?

[dvdbunny1]

Hi there,

I have a movie file that is in XVID High definition format It is 700MB in size and with a resolution of 960 x 528 the movie has AC3 5.1 Sound and has a length of 43 minutes. All that i want to do is re-encode the resolution from the above to 720 x 480 or less and leave the sound untouched.

Does anybody know of any software which has a wizard that can convert files or is easy to use. I don't mind buying the software or using a trial, it would be better if the software is free to use. The software must be able to do what i wrote above in the first paragraph.

Any help much appreciated


Many thanks

first of all: don't double post

you can use avisynth to do the resizing

what is your target format? xvid? dvd?

[dvdbunny1]

Sorry about the double post

i have already used avisynth, i found it too hard, do you know of anything else. I want to convert it from xvid to xvid just a lower resolution so i can play it on my xvid stand alone player.

Its not too hard. You just need a sample avs script. What format is your file. From the size it seems avi. For avi create a script as

AviSource("c:\video\somefile.avi")
BicubicResize(480,720)


I did not look at your aspect ratio, so adjust the numbers abovve to get the correct ratio. Save it with an avs extension and open in virtualdubmod. Then save as avi and you should be good to go.

Thank you for the reply,

Ok i have installed avisynth 2.5
and virtualdub 1.6.3 experimental

now i am using windows XP and when i go into start, program, avisynth i find some names which are:

avisynth documentation
avisynth online
download plugins
example scripts
license
plugin directory
uninstall avisynth

Now all i should do is create a new text document and i can do this by righ clicking with my mouse and choosing New then Text Document

Then what do i name the text document?

then inside the document i copy and paste what you posted

AviSource("c:\video\somefile.avi")
BicubicResize(480,720)

Then how do i save the documents as a avs extension?

Then save as avi how do i do that?

Where should i create the text document for the script and where do i put this document.

Also the resolution of my source is 960 x 528
I don't want to lose much quality so should i leave it at 720 x 480
and how come your script is written back to front as you havve written it 480. 720 shouldn't it be 720,480?

I hope you can answer my questions


Many thanks

I have tried what you said with what i have written above, and have had no luck, Please answer my questions in the above post, i must be doing something wrong, i have read some of the guides on avisynth website and i am still having problems.

extension must be .avs
open it with virtualdubmod

[dvdbunny1]

how do you create the extension .avs?

[E-Male]

just (re)name the file to it (maybe you have to activate extensions in the explorer option)

[dvdbunny1]

I am sorry but i am a complete newbie, i need you to explain this to me in an easy way, how do set up that in explorer options, where can i even find those options

[nexx]

Tools > Folder Options > View > uncheck 'hide extensions for known file types'

Then right click on the file and rename it to .avs
