Does anybody know how to convert 16:9 to 4:3 with black borders?

[tuanvn.2007]

I have some video ripped form HDTV. All of them are in ratio 16:9. I want to resize them to the ratio 4:3 (640x480) by creat 2 black bar on the top and bottom of the video by VirtualDub but I don't know how to do it! Can somebody help me, please!!!

I changed your topic subject. Just "Does anybody know" doesn't say anything aboout your topic.

Have you played around with the resize filter in virtualdub? Under Video->filters and set the new size to 640x480 and select the letterbox to aspect ratio 4:3. View the preview to check that it looks okey.

why?

i also think it's good form to at least post an image of unprocessed source.

Well, resize the video to 720x360, then add borders (60 pixels on top and bottom). An AviSynth script is:

avisource("myvideo.avi")
bilinearresize(720,360)
addborders(0,60,0,60)
add convertto whatever colorspace you need.

This should work (or something close to this).

Did you try virtualdub?
Import the avi, add the resize filter under Video->filters and click on it to change to 640x480 and select the letterbox to aspect ratio 4:3.
Select Video->Compression and choose a video codec like xvid codec.
Select Audio->Direct Stream Copy
Select File->Save as avi

I prefer AviDemux for stuff like this myself.

In Avidemux I choose the filter to resize but I can't save (file .>> save >> save video) the video with the fiter (the destination video is the same with the source file). Do you knoe the resolution for this problem?

Question: why would you want to?
if you are putting them on a DVD you should leave them as 16x9 and set your DVD player to letterbox the DVD for a 4x3 TV.
