Making the Video remain 320x240 when i put it on dvd

[yea]

ok, i have a bunch of small videos, like 320x240, and i want to put them on dvd. When i put them on dvd though( i use Nero), the size of the videos is increased to fill the screen. This is a problem though, and it makes the videos blurry, too blurry to see. I dont really care if the video file when played on my dvd is 320x240, i just want to be able to watch it clearly. Is there anyway possible to stop Nero from enlarging my video when i put it on dvd?

That is not a valid DVD resolution, and Nero will never let you do it. You're going to have to change the resolution to 352x240 (VCD) for it to be valid for DVD.

Use avisynth and frameserve it to a mpeg2 encoder.

AVISource("source.avi")
LanczosResize(304,208,0,0,320,240)
AddBorders(24,16,24,16)

I'm curious. Why resize? Why not just add borders to bring it to compliant size?

[yea]

well, i dont want to resize it, nero automatically does it when it burns the dvd. and i mistakedly type 320x240 for the resolution. the video res. is actual 352x240. i like the idea of adding a border around the video to make it the right res. so the video would be 352x240 and a black border would fill up the rest of the screen to make it 720x480, how would i do this exactly?

You can keep the video at 320x240 and add borders to bring it up to 352x240 instead. Less border, more picture on playback. Look at What is DVD (top left) for compliant resolutions. Look at FitCD for resizing. Read guides to understand how it all works.

Many programs can do what you want. TMPGEnc for instance has a custom resizing option which can center the 352x240 image in a 720x480 frame.

Or you could Use VirtualDUbMPEG2's or VirtualDubMod's resize filter. It has an "expand frame an letterbox image" option. VirtualDub can't save as MPEG so you'll have to frameserve to your MPEG2 encoder or save as an intermediate AVI file.

Or you could use the AVI script suggested by Stormin Normin with:

AVISource("source.avi")
LanczosResize(352,240,0,0,320,240)
AddBorders(184,120,184,120)

[yea]

perfect. thanks guys

Sorry if I missed something, but did you say that your video is actually 352 X 240 already ? If so, then you don't need to worry about resizing anything. You don't mention whether your sources are AVI (and codec) or MPEG or anything, so it's hard to guide you anywhere from here. Can you post screenshots of your files in GSpot ?

I'd be looking at ditching Nero, as IMO it "baby-steps" you far too much to the point where it doesn't allow you the control you require for more "obscure" DVD projects such as this.

That doesn't make any sense. You'll alter the aspect this way.

[guns1inger]

I meant add top and bottom borders to bring the overall res up to 352x240. Keeps the original AR and size instact, but brings total res up to minimum DVD Spec

[lordsmurf]

Still doesn't make sense.
The 352x240 is 4:3 also, like the 320x240 1:1

If you add border, you'll squash the image.
You would have to add (4 on top/bottom and (:3) on sides.

But that won't work either.

Just re-encode it.
Or get the source and do it over properly this time.

[gadgetguy]

Since I was the first to suggest adding borders, I want to clarify. I originally mis-read the original to be what Yea was actually asking. The source was a proper DVD spec (though minimum), but when played full screen it looked bad. My thinking was that the bitrate was probably low and that enlarging the image would make it worse. So instead of resizing, I was suggesting to add borders so that the image would remain the same size but the framesize would be increased to fill the screen, (albeit with black border). Yea confirmed that was what was being asked. (The originally stated framesize was incorrect at 320x240, but was actually 352x240). Adding the borders in this manner will work for this application.

If the original question is taken at face value, then Lordsmurf is correct. Just adding border would indeed squash the image because of the Aspect Ratio differences. This can be compensated for, but would probably result in noticably more degradation of the original video.

But make no mistake, in both cases you are re-encoding the video and there will be some degradation. In the case of adding border to the 352/240 to bring it to 720/480, the degradation is probably going to go unnoticed, whereas the other option will probably be glaring.

sound like vcd... should be able to make a dvd using these with TDA

No, not VCD. 320x240 is not part of any disc spec.
