Suggestions for improving Love Hina footage quality

emopunk1 · Post by **emopunk1** » Thu Mar 24, 2005 3:02 am

After looking through some of the older posts, I was wondering if anyone who has worked with Love Hina footage could post an .avs script that actual produces good quailty. I've been trying to figure out if I should IVTC the footage or should I just use a de-interlace filter, since most of the posts regarding LH didn't have a definite answer. I also was wondering if there is any other filters I should use to improve the image quality (and yes, these are from R1 DVDs).

This was the most recent script I used:

Code: Select all

mpeg2source("F:\LOVE_HINA_VOL_1\VIDEO_TS\eps2.d2v",cpu=4)
#Telecide(order=1,guide=1)      
#Decimate(5)
TomsMoComp(1,5,1)
converttorgb32()

any help would be appreciated

I have the footage on my hard drive and am working with it, but I haven't actually gotten to the postprocessing stage yet, so I don't have any concrete suggestions.

However, just from looking at it, I'd say it could probably benefit from a light, easy Deen() and an MSharpen().

If it wasn't for the fact that I'm in the middle of encoding a crap-load of MPEG-1s, I could actually decode the intro to the show to see if the IVTC commands screw up the motion. DGIndex read that it switches back and forth between Film and Video a lot, so I don't exactly know how well an IVTC would work, at least without tweaking it to next Thursday (something I'm not experienced enough with Telecide or other IVTC filters to do yet).

However, I did get a much cleaner picture by using these commands on it:

deen("a3d", 3, 10, 12)
ColorYUV(gain_u=4)

Any sharpening afterwards would be up to you; I rarely use sharpening filters.

Well, as concerns IVTC, I noticed that some of the episodes have the nasty habit of changing their field order for some scenes... I know that at least episode 16 does this.

AbsoluteDestiny suggested either running DGFix on the affected VOBs or using the 2.0.x version of Decomb (4 Legacy); since I don't have the DGDecode package, I went with the latter, and it works great (except just a hair slower).

Thanks, guys

So far using:

deen("a3d", 3, 10, 12)
ColorYUV(gain_u=4)

seem to have helped. I'll try MSharpen again later.

the problems seems to be with the second episode (I'm ripping individual episodes, btw) during any scene with motion. Using telecine and decimate with the settings I posted seem to still leave interlacing during scenes with mouths moving or any type of motion. when I checked ep.1, there really wasn't any problems w/interlacing though (and for some reason, it looks a lot sharper and cleaner than eps.2, even though I didn't apply deen, msharpen and ColorYUV)

Try setting order=0 instead and check those scenes again. If they come out clean, then episode 2 may be another case of the switching field order (see my last post) or it may just be completely bottom field first.

So far, setting field=0 seems to help, though there is some minor lines during close-ups with the mouths moving, but for the most part, it seems better.

thanks again

Update:

The third vob I have has the second half of episode 3 and the first half of episode 4. The problem is that both have different field types, so if use field order=1, then episode 3 looks good, but episode 4 looks terrible. So, do I need to cut the vobs? (and which program)

I also used DGIndex again and found out that all the episodes on disc 1 switch between top and bottom field throughout.

I tried to use decomb4 and decomblegacy and got a message in Vdub saying:
"Telecide does not have a named arguement "order"

Take out the "order=1".

Decomb4 seems to work now (Decomblegacy kept telling me to convert to YUY2)

I tried to add post=4, but Vdub keeps telling me:
"the named arguement post to telecide has the wrong argument"

So I dropped it from the script and it seems fine.

anyway, I think the color and sharpness needs a little more tweaking, but at least the lines are pretty much gone.

Here is my current script:

Code: Select all

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\alternatives\Decomb4.dll")
mpeg2source("F:\LOVE_HINA_VOL_1\VIDEO_TS\eps3.d2v",cpu=4)
Telecide(guide=1)      
Decimate(5)
Deen("a3d", 3, 10, 12)
ColorYUV(gain_u=4)
converttorgb32()

If anyone has something to add, please post.

Thanks again, Scintilla
