How can I increase my resolution (using Adobe 6.0 or virtual dub)?

I take it you're talking about taking something like a 320x240 resolution video and making it something larger, like 640x480? Unfortunately, not matter what you do, it's not going to look as good as native high-res footage. But, it is possible to make it look halfway decent. My recommendation would be a combination of Lanczos Resize (should be in VDub now natively) and one of the sharpening filters. Use the Lanczos to increase the resolution to what you want, and then the sharpen to try and eliminate some of the blurring that occurs. Some other filters may not be a bad idea- see the main guide for some hints on using the 'cleaner' filters.

I assume you're talking Premiere 6 when you say 'Adobe 6' (there are hordes of Adobe products). When you import footage into Premiere, it automatically resizes it to the resolution you're editing at, IIRC. However, I generally don't trust it to do it well, and if I have to work with something that starts out smaller I'll do the resizing before importing it so Premiere doesn't have to resize the footage. I do know that AfterEffects' scaling/zooming works quite well though- it again combined with the sharpen effect looks pretty good at reasonable zoom levels.

you said "I take it you're talking about taking something like a 320x240 resolution video and making it something larger, like 640x480?"

Yup as a matter of fact thats what Im trying to do. Most dvds rip at 320x240 resolution (that is after I run it thru dvd2avi and tempenc). Is there anyway to get it to rip at 640x480???

you said "My recommendation would be a combination of Lanczos Resize (should be in VDub now natively) and one of the sharpening filters."

lanczos resize? I didnt see it in virtual dub. Where do i find it in virtual dub?

Thx for the help

The resize comes with the AMVapp.

Most dvds rip at 320x240 resolution (that is after I run it thru dvd2avi and tempenc).


Errr...first off, all my DVD's rip at 720x480, and I was pretty sure that was the norm. And what are you running it through TMPGenc for (I'm assuming that's what you're talking about). Just make the d2v file in DVD2AVI and import it into Premiere with AVIsynth.
There's a fine line between genius insanity...and I've crossed it 67 times.

I know this is the wrong place to post this but...

Since I downloaded the virtual dub filter packs "AdvancedAVS1_00" and
"AMVapp1_02b" my audio files have been compressing incorrectly. That is as the movie progresses the audio gets gradually more and more out of sync. By the episodes end (25 mins) my sound is off by over 3 seconds. Ive tried using most audio compressors and each has the same problem. I realize that there is probably a 0% chance that the video filters are affecting my audio syncing, but it was the last change I made b4 I started noticing problems. The only other change I made was I slightly changed the bitrate to 700 from 756 (again this shouldn't make a difference).

While I'm at it, what sound compressor does everyone use in virtual dub?

Everyone uses mp3 compression in vdub. Its likely that your framerate has messed up or something and it causing the audio to be out of sync.

Either that, or you're using VBR MP3 for some reason.

ABR is also known to cause synch issues.


:\ Only use CBR when encoding to a AVI file.

I should also mention that Im using DivX (5.0.3) to compress the video.
Is it possible that my sync problems have something to do with my using DivX as my video compressor?

As far as framerate becoming an issue I definitely think you have a case. My guess is that the audio runs at a framerate of 29.97 and my video runs at 30. I'll try setting both of em at an even 25 and see what happens.

Alot of people prefer XviD since it's free and non-commercial.


Get Koepi's version @
http://roeder.goe.net/~koepi/

The guides off the main page go into how to compress videos with XviD so that they can be played back on computers that don't actually have XviD installed(but they need to have DivX4/5 decoders installed).


As for the avatrs. Click on the profile link at the top & scroll down near the bottom. You should have a option for uploading a avatar.

You should be able to change either the size or the resolution in Photoshop (or most other decent image editing programs to get just about any picture/image down to the avatar size (though how good it will look may be in question). You'll probably just want to play around with it for a while and see what works well.
