View Full Version : Weird line at top and bottom, "graphing" lines (urgent, please help!)

Hi!

First, I have a major problem, lines that seem to be going like a parabula or a graph: look at his shoulder (http://xs123.xs.to/xs123/08016/nnedi.png) here.
I'm lost as for how to make this look better.

Also, if you notice, there's a strange line at the top and bottom of this image. This isn't an effect of filters, because it's present in every video I open (including H.264 and DivX 6.6/6.4), so it's some decoder's fault. I have ffdshow (libavcodec in the configuration) decoding all of these.

Since I see these lines, it also means they'll go into anything I encode. I'd really like to get rid of them. (another image of the lines (http://xs123.xs.to/xs123/08016/line2.png))

Also, I'm in a hurry to finish a script and encode (deadline), so I'll appreciate quick help ><

Thank you!

Firstly, please don't resort to attention grabbing titles like "urgent" etc. I can't imagine how urgent encoding something can be.

OK, now to your issues - the first issue looks like aliasing. You should try an anti-aliasing filter like AAA or TIsophote (:search:). The issue may have been caused by improper deinterlacing in the first place. You should post your script here.

Second - you sure you get it in every single video? Looks like the usual dirty edges on DVD videos which we usually crop away. In your case, even if you crop the edges, those lines don't go away?

@ "urgent":
I was originally going to put it in the start, but decided to put it at the end because it could annoy people =\ I figured it might be considered less attention seeking if I didn't do [URGENT] ..

I added it because I don't want to keep my friends waiting :\
In any case, I apologize.

First issue - Aliasing? sure? It looks a bit too... how should I say.. soft to be aliasing. Either ways, I am using a slightly modified version of AAA (in comparison, AAA's default settings perform slightly worse when it comes to aliasing as in "steps" in lines), so, hmm...

I'll try TIsophote too. Anyway, I wasn't the person who deinterlaced it (and that person no longer has the source).

Second issue - Sorry, it appears that using AddBorders() creates a line that looks very similar. I was using Crop() and then AddBorders() earlier, and happened to stumble on two videos that also had it.

Now, I just cropped and resized and it's gone. Thanks =p I would not have checked again without this reply =x

btw, which resizer do you recommend I use for something like this?
Is there some website or FAQ that explains the differences between each resizer?

Thanks.

Just tried TIsophote. Even at max settings, that line's shape remains the same.

IMO, his source might not be a dvd, but I could be wrong. :)

Post a sample, and what script are you currently using?

Yup, not a DVD. It's a TVRip.

A sample of the TIsophote filtered video? >.>
The video looks like that before any filtering and so I need suggestions on what to use to make it look better :x

Yup, not a DVD. It's a TVRip.
And I'm sure you recorded/ripped it yourself, right? :rolleyes:

Could someone close this thread due to rule #6, please?

"TVRip" to me very much sounds like he downloaded it (especially in conjunction with anime and having to "script and encode" it, and "urgently" at that); if you record it yourself you usually call it a "recording" or something similar...

np: Richie Hawtin - Track 09 (Concept 1 96:CD)
