View Full Version : Strange visual tearing/smearing with Anime encoding, w/ screenshots

This isn't true for all anime I have been encoding but, about 70% of the time the final product after encoding contains irritating horrizontal tearing/smearing. I prefer to use StaxRip, I seem to get a better quality to filesize ratio but, StaxRip also seems to be related to the problem.

I can take the same project and encode using RipBot264 or Nero Recode and get decent results but, I really prefer StaxRip.

Here are a couple screenshots of the tearing/smearing from my x264 encode of the anime "Witchblade." The problem only becomes apparent when there is fast action in the animation, as seen below...

What is causing this!?

That's not "tearing", that's interlacing.

I've also seen it occuring with my live-action films every once in a while, but mainly with anime. And like I said, it seems to only be a problem when I use StaxRip (version 1.1.1.0 BTW).

As Dark said, it is interlacing. The shots you posted are probably field blended.

Great, thanks! So, I just used one of the Deinterlace profiles in VLC player and all is well. :)

That's not the way to fix it. Encoding interlaced material as progressive is an incredibly bad idea and wastes an enormous number of bits.

Noted, thanks Dark. I'm using wizard-style apps to get the job done so I don't have alot of fine-tune control over the encode. RipBot264 seems to automatically detect progressive or interlaced content so, if I run into the problem I'll just fall back onto RipBot264 (as opposed to StaxRip).

Enable the yadif filter in StaxRip.

I'm 100% sure that your source is in fact soft telecined 23.976 source to 29.97. I use two methods to find if source has 2:3 pulldown. eac3to and mediainfo. if one of mentioned tools detects pulldown then dgindex is set with film switch. This the best method if you care about quality.

I've no experience with NTSC but what StaxRip does is reading the last line of the d2v file, it contains a percent value telling how much percent the souce is film and if a defined threshold is reached (95% by default) then it opens the d2v file with force film option. MeGUI does this also, that's how I learned about it, a MeGUI developer told me about how to do this. I'm from germany, never user NTSC, never watch and encode subtitles because the translations and my english is good enough.
