Anime video help question (not play back help)?

I am wondering if there is a way improve the quality of a vhs rip anime (I am not expecting to become a dvd-rip) but little improvement is better nonetheless. Can you please list the name of some the softwares I'll need or site to guide? I already know about dvdrhelp.com and doom9.org

Secondly, is there a way to increase the screen resolution of a anime? For instance, if it was rip and encoded to 320x240 but I want to change to 640x480, is that a good idea to do it. Again, please give some suggestion how to do that. 320x240 looks pretty bad on a 800x600 monitor(full screen).

The short answer is that it's too much work, there's no magic fix. If there was you would have heard about it on doom9 or whatever.

What will make the rips most watchable is to burn VCDs of them and watch them on TV. TVs are far more forgiving of compressed color and stuff like that. Of course you need a DVD player that shows VCDs and may not be interested in doing this even if you do, hence the short answer. But if you are going to go the VCD route then VCDHelp is a good site to get info from.

TMPGEnc will convert divX to MPEG (which you need for VCD) and you can also apply filters while processing to try and get the video to look nicer. You might at least try making mpegs out of the old files and watching them on your comp.

Re-encoding to a higher size is not going to help anything. If you think about it, when you go to fullscreen you are stretching a file with not enough information. Re-encoding is the same thing.

I partly disagree with you. Firstly, VCDs are the spawn of the dark lord himself and should be wiped off the planet .

Secondly, certain filters can make a decent difference on a "bad" file. For instance, you could try running it through some noise-filtering and a smoother and then sharpen the file.

You could try, for instance, these filters (for AviSynth):
Mftoon: http://mf.creations.nl/avs/functions/mfToon-v0.52.avs
Mftoon needs the DLLs from here: http://mf.creations.nl/avs/
FluxSmooth: http://www.avisynth.org/warpenterprises/
UnDot: http://www.avisynth.org/warpenterprises/

If you don't know how to use AviSynth, an example script file would look like this:

Loadplugin("C:\Progra~1\AviSynth\plugins\aWarpShar p.dll")
Loadplugin("C:\Progra~1\AviSynth\plugins\MaskTools 142.dll")
Loadplugin("C:\Progra~1\AviSynth\plugins\WarpSharp .dll")
Loadplugin("C:\Progra~1\AviSynth\plugins\FluxSmoot h.dll")
Loadplugin("C:\Progra~1\AviSynth\plugins\UnDot.dll ")
Import("C:\Progra~1\AviSynth\plugins\mfToon-v0.52.avs")
AviSource("C:\Progra~1\Encoding\Source.avi")
Undot()
FluxSmooth()
mftoon()

Paste that stuff into your text editor of choice, change the paths so that they're correct for your system and save the file as an .avs, then open it up with virtualdub, choose whatever codec you want to use, configure it and start encoding. With mftoon, this process will take positively ages, though it ain't *that* fast without it either. If you want somewhat comparable results without so much wait, you can replace mftoon with SharpTools, remember to change mftoon() into ssxsharpen() in the script for that.

Note: Don't bother to do this unless you really want to slightly improve the quality of the file. Encoding is bloody slow, especially with these filters

Oh and increasing resolution is generally pointless, though there are resize scripts which try to fool the eye into believing there's more detail in the file than there was in the source. I've never tried them myself though.

Here's a topic on mftoon on Doom9: http://forum.doom9.org/showthread.php?threadid=53364
And here's one on SharpTools and also DetailIllusion
