resizing/cropping VirtualDub/NunDub doesn't stretch

[pintree3]

Hi,
I have an avi video whereby the image is longer (height-vertical) than its length-the people appear thinner than they should. So I used VirtualDub and NanDub (They appear to be one and the same program but with different names but that's another question.) to resize the image. I used various criteria to do so. G-Spot showed it to be 528x480 so I tried 500X480, 480X480 and a few others. When I view the completed file I do get a new ratio--that is the rectangle/frame is different but the image has not stretched to what I had hoped for. What appears to be happening to me is that, it is resizing the frame but at the same time it is keeping the image as it was (bodies still seem to be long)--as if compensating somehow. Maybe this is normal so my question is how does one resize the image (with or without resizing the frame size) so the people and objects in the movie appear normal and not stretched?

Thank you

Your going about it all wrong, try reducing the height and not the width. reducing the width will only either keep it the same or make it even worse. So do it again and this time try the height at something like 300 bit lower or bit heigher but roughly that. It's not the width that needs lowered like you have been doing, it's the height.

You've apparently obtained a video that has had the upeer and lower "black bars" cropped off (to reduce filesize):

(In VirtualDub, set "Video" to "Full Processing Mode" and "Audio" to "Direct Stream Copy")

1) Load you video into VirtualDub
2) From the "Video" dropdown menu, click on "Filters", then click on the "Add" radio button and doubleclick on the "Resize" filter
3) Set "New width" and "New height" to the SAME resolution as your original .AVI (In this example, I'm assuming it's 720x480)
4) Put a checkmark in the box labelled "Expand frame and letterbox image - and enter a multiple of 16 in "Frame height" (Perhaps 208, or 192 to approximate 16:9 - which, in this example, will increase the height from 480 to 688 or 672)
5) Click on "OK" to return to the "Filters" window

6) Once again, doubleclick on the "Resize" filter
7) Set "New height" to 480 (This will reduce the ENTIRE image, including the black bars to 480 pixels of vertical resolution). Click on "OK" until you get back to the main VirtualDub window
8) Save with a new filename

Well they don't really have to make a new width, but i suppose it might be the easiest option. I would have made a new height but....

if it is an mpeg-4 file (divx/xvid/nero, etc.), and you would rather avoid encoding the movie, try this:

download and install the latest version of divx (if you don't have it already), and run the "divx decoder configuration".

look around the tabs at the top, and you will see a box that says "aspect ratio"... try "16:9", "4:3", etc, and play the video each time until you get what you want


good luck

I tried this and doesn't change my video's, they just play the same. BUT i have just thought of something, try media player classic, you can adjust the height and the width by fiddling around with the number buttons on the right of your keyboard.

[anonymez]

the "change aspect ratio" in the divx decoder configuration works ONLY with movies that are being decoded with the divx decoder... i have 1 or 2 divx movies that are much too wide, so when i want to play them, i change to option from "maintain original" to "16:9" and it plays back perfectly.

Ok i'll try that and get back to you.

sorry to take so long to reply
dx50's answer worked but somehow I lost sound along the way
i tried various methods always creating different problems -sound went out of synch, is one example
I gave up
thnxs to all of you
