Canon Xi samples, some are deinterlaced. Large.

I created a 1.5 minute file from my Optura Xi. It was shot indoors on New Years day in 16:9 mode. The file was edited in Vegas and encoded into WM9 with VBR 75% for the audio and VBR 6Mbps for the video (two pass encoding).

These files are 70MB each. http://www.photomosaic.com/movies

I am not sure how WM9 deinterlaces, but it looks soft, so maybe it is just chucking one set of fields?

CanonXiShort.wmv is the interlaced file rendered into WM9

CanonXiVirtualDub-deinterlaced.wmv was deinterlaced in VirtualDub with the default setting which blends the fields. This method is known to ghost moving edges, but otherwise has no other artifacts. I like this method because the ghosting looks like film motion blur.

VirtualDub-Adeinterlace.wmv uses a smart motion-detecting plugin from http://www.alparysoft.com/prod/deinterlace.php


VirtualDub-Smart.wmv uses another smart algorithm (http://neuron2.net/smart.html)

The edges of the smart algoritms are sharper, but also have jaggies, and you can sometimes see swimming textures in the images, so I am not sure they are best!

first.ASF is an mpeg-4 output direct from the Xi. This plays in WM9 but will automatically download a codec.


For general reference: http://100fps.com/

This one I have not tried yet:

So you are testing de-interlacing methods? Do you have a
conclusion? And if so, what is it? (not everybody has the time
or bandwidth to download all of your sample movies, especially
at those sizes.)

I tested them for use with DV only.

The 'Smart' deinterlace filter for VirtualDub has artifacts that are very serious, so I can't use it.

The AreaDeinterlace filter is good (http://biphome.spray.se/gunnart/video/) and I would be happy to use it.

The alparysoft seems best, but it has a logo, but you can trick it in VirtualDub by making the image 800 pixels wide before feeding it to the filter, and then crop it back to 720 wide.

I would like to spend more time comparing the area-based to the alpary, and I made a DVD to compare them -- but I want to watch them on a non-HDTV so I have to bring it to my mother's house because I am not sure if my DVD player and HD set are doing any additional processing.

Someone pointed out to me to try these settings in Smart Deinterlace:

denoise on
cubic on
motion threshold = 5

Once I did these, my artifacts went away, and now I tend to believe this is the best free filter. At least I am going to use it rather than retest them all.

Did you look at KernelDeint from the same (Donald Graft's) site? The last time I checked in his forums it was widely regarded as the best deinterlacing filter where the source material was entirely interlaced.

There is also quite a lot of info about it on his journal page.
