Needs deinterlaced, bad.
Cool clip though, nicely unique.
you're making me look shlt up ! .....

Deinterlacing - Wikipedia, the free encyclopedia@@AMEPARAM@@/wiki/File:Question_book-new.svg" class="image"><img alt="Question book-new.svg" src="http://upload.wikimedia.org/wikipedia/en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png"@@AMEPARAM@@en/thumb/9/99/Question_book-new.svg/50px-Question_book-new.svg.png
Most modern displays, such as LCD, DLP and plasma displays, are not able to work in interlaced mode, because they are fixed-resoution displays and only support progressive scanning. In order to display interlaced signal on taken at different points in time are re-combined to a full frame displayed at such displays, the two interlaced fields must be converted to one progressive frame with a process known as de-interlacing. However, when the two fields once, visual defects called interlace artifacts or combing occur with moving objects in the image. A good deinterlacing algorithm should try to avoid interlacing artefacts as much as possible and not sacrifice image quality in the process, however this is a very complex task and there is considerable doubt that 'ideal' deinterlacer is practically possible.

Not all interlaced video material needs de-interlacing. Typical movie material is shot on 24 frames/s film, so when converting film to video using telecine, so each film frame can be presented by progressive segmented frames (PsF) with 4% speed-up in 50 field interlaced PAL/SECAM, or using a 2:3 pulldown process in 59.97/60 field interlaced NTSC (which can be restored to 24 frame/s in the TV set using an inverse telecine process. DVDs can either store movies using one of these methods, or store original 24 frame/s progressive video and use MPEG-2 decoder tags to instruct the video player on how to convert them to the interlaced format. Most movies on Blu-ray discs have preserved the original non interlaced 24 frame/s motion film rate and allow output in the progressive 1080p24 format directly to display devices, with no conversion necessary At present (2008), Blu-ray does not support 1080p at 50 frames/s, but does support 720p and all interlaced formats at 50 frames/s; (here are Blu-ray discs authored in 1080i format which is used typically for live footage, and such material does need to be deinterlaced. Some 1080i HDV camcorders offer PsF mode with cinema-like frame rates of 24 or 25 frame/s. Such progressive frames are packaged within the interlaced signal and can be reproduced by standard consumer television equipment.

Deinterlacing techniques require complex processing and thus can introduce a delay into the video feed. While not generally noticeable, this can result in the display of older video games lagging behind controller input. Many TVs thus have a "game mode" in which minimal processing is done in order to maximize speed at the expense of image quality. Deinterlacing is only partly responsible for such lag; scaling also involves complex algorithms that take precious milliseconds to run.

Haha!
It doesn't have to be that complicated. :P
One simply must find the deinterlace settings in one's video editing program when rendering one's video clip.... :D
Try one of the options. Render a very small clip. Repeat as necessary until all the horizontal lines smooth out. ;)
Then render the whole thing with the settings that work the best! :thumb:
