De-interlacing method

[Pavel Houda]

I am using pair of consumer camcorders - AVCHD for my 3D @ 60i. When I play the resulting video on TV, it seems o.k. due t the decent de-interlacing technique - I am guessing. When I play back on computer or over internet (YT/Vimeo) I have annoying artifacts due to interlacing. I tried to use several de-interlacers, but I canot find one that works well. Does anyone have any suggestions for good de-interlacer?

It depends on what platform you're on. Revision FX's Fieldskit is pretty good & also works on many platforms. If you're on Mac, use compressor & set the deinterlacing to "blend". On a budget, try JES Deinterlacer.

Thanks Arnie. I work on either Windows or MacOS and would like to use decent de-interlacer on either. Your advice is very helpful and I appreciate it.

Hi
Try ffdshow with deinterlace checked (yadif method)
This gives me smooth result!

[Pavel Houda]

Thank you Prech. I'll give it a try.

I'll second yadif. It beats the adaptive, motion-compensated de-interlacer in Compressor hands down (and every other software de-interlacer I ever tried).

[Pedro Ferrando]

When is the best moment for de-interlaced? Do you de-interlace L and R clip separeted or do you de-interlaced once the are ensambled?
Thank´s

De-interlace as a first step, fresh out of the camera. Any transcoding or frame manipulation might have the unintended consequence of blending the two fields from the camera - which need to be pristinely separated for proper de-interlacing.

How can i play Sony TD10 native files with Stereoscopic Player
with good deinterlace (bob, yadif, etc)?

I'll look into the ffdshow, especially since I'm doing all my stereo work on PC.

Does anyone have a sample interlace vs. de-interlaced stereo comparison samples link, so I can see them side-by-side?

Stereoscopic Player will deinterlace on the fly. Depending on your video card, you'll generally get quite decent hardware deinterlacing.

FYI - AVISynth can run YADIF as well.

I have only a geforce 210 card. Can i use this with Stereoplayer for high quality deinterlacing?

I've never seen really bad deinterlacing from an NVIDIA card, but, reviews say otherwise for the 210 card:

AnandTech - Quick Look: MSI?s GeForce 210

"The quality is reminiscent of vector adaptive deinterlacing, however it’s not as clean as what we’ve seen on the GT 220."

It's still worth a try.

When i check deinterlace to on in Stereoscopic player, it will use the gpu hardware deinterlacing? Sure?
After turned on, the horizontal lines disappear, but i don't get smooth motion. I see 25fps progressive (from 50i source), and not 50fps.
I can see my 50i mpeg2 videos at 50fps deinterlaced with bob or yadif method via ffdshow. But when i
load native videos from TD10, i cannot change deinterlace method at "video properties" under used filters.
Only 3dtv.at AVC/MVC decoder is used, and i cannot setup here anything.

So i really need a new video card? A GT240 support good deinterlacing?
thx
