How do I resize an AVI and keep the quality

[bobbysox]

Let me start by showing you a G Spot output.



Notice the size 720*272 now I've seen this size quite a bit and I wonder why just that size and not the standard sizes?
So ok. Let's move on. I now have this weird size in an AVI and I'm going to run it through TMPGnc.

I get a mpeg file that looks ok but when I try to run it through TMPGnc I get the error below. Now I'm sure I can work around that with another app that will ignore the sizing and create the Video_TS Audio_TS folders but should I resize the file????????



If I tried would it look like crap? I just don't want to wait for the next 10 hours or so and have waisted so much time.

If you do not convert your file into a DVD compliant resolution then it's likely that most DVD players won't play it. Look up "What is DVDR" (over there <-<-) for all the acceptable resolutions.

Well the accecptable are in bold red above, are they not?

Do you have any idea why these AVI's are created in "off beat" resolutions and do you know of any way to keep the quality of the file?

Is it so that the resizing of this file to make it DVD compatible would just result in disappointment because of degraded quality.

Even with all the settings in TMPGnc it still can't do the impossible and from my experiences with digital photography I know that resizing at least upwards usally doesnt work well. Some things just can't be done with satisfactory results.

What would do? Leave it or give it a go?

If you'd give it a go, could you suggest some settings for the encoding please?

thanks!

I've never come across an AVI that didn't need resizing if to be converted to (S)VCD or DVD. Do it in VirtualDub using Lanzcos 3, then frame serve to encoder.

Do a 5 minute clip and see

They are created for viewing on a PC.
A PC has square pixels, a TV does not. The 'odd' sizes you see are used to maintain the correct aspect ratio of the original material when viewed on a PC.
