It would be handy if we could start adding this to our comparisons. It takes seconds to find out.




How do you take a picture of it though?

You've got a "print screen" key on your keyboard.
Don't be afraid to use it. :D

Print Screen, open Photoshop/Paint/Whatever, paste, crop away, save as PNG or GIF.

I tend to just type in whatever the bitrate is but if you like you can post a screen capture. It gives a wee bit more detail.

I had to take my computer in to be looked at because the damn thing keeps getting the blu-screen-of-death every time I work the CPU hard, probably due to a falty fan because it gets over heated. Due to that I am using my old XP computer (soooo slooow). I don't have the rest of the caps for the Hard-boiled and Brazil reviews so it'll take a few weeks for those to be updated. I just forgot to transfer those pics over to my other harddrive.

Finally remembered to update bnb.zip with 1080.bat and JPG.bat whcih will be handy as I'm thinking I might do a slew of HD comparisons soon, been slacking.
1080.bat - Resize to 1920x1080 for comparing DVD's to BD/HD-DVD/HDTV
JPG.bat - Convert to JPG for BD/HD-DVD/HDTV captures

The quality difference between uncompressed PNG's and these JPEG's is near impossible to see on my projector, let alone on a monitor and it reduces the file size DRAMATICALLY.

Tom, I've been doing some comparisons between different resampling methods and there's a noticeable difference between them. As an example your use of IrfanView (and presumably Lanczos) results in an image that is noticeably sharper than one from convert.exe and the lanczos filter there (as in the batch files).

Are you saying that Irfan's Lanczos is different from Convert's Lanczos?
That's strange. In my experience, Irfan's Lanczos is better than Bicubic when it comes to jagged edges and aliasing, but it doesn't really sharpen the image.

Thanks for the heads up, though. I'll do some testing on that as well.

How do you apply Lanczos filter in Irfan? I tried doing a batch upscale + conversion from DVD res PNGs to 1080 JPGs and they all come out with horrible artefacts.

Lanczos is the method, but there's a lot more to it such as the number of taps, they both just do it differently.

It's there as the resampling method for the normal upscaling. Or just download the bnb.zip as it has a batchfile for that.

I should have a neat method for HD captures very soon. Just need to do some playing about to make it portable.

UPDATE:
FUCK IT I had a lovely method that involved directshowsource to vdub but then I realised that vdub doesn't allow saving images and my script wouldn't work with vdubmod...
Tomorrow I'll have a look at MPC-HC as that has internal AVC, VC-1 and MPEG2 decoders. Combined with Haali (splitter and renderer) it might be the neatest solution.

There should be very little difference between decoders but it's the renders that cause problems plus something that anyone can use easily is good.

Okay I'll post up a proper guide sometime but it will basically just consist of Haali + MPC-HC and its internal MPEG/VC-1/AVC filters with DXVA disabled and the Haali renderer as output.
http://haali.cs.msu.ru/mkv/MatroskaSplitter.exe
http://sourceforge.net/project/showfile ... _id=170561
I need to test opening all varities of m2ts and evo's as an additional step may be needed for the latter (rebuild or demux using evodemux).

It's a bit of a PITA but is still only one install you should have anyway and a couple of settings in MPC-HC which can be made to be portable if I distribute it with settings in a .ini file. Because this is directshow there's no framestep backwards and seeking is shit but there's no other straightforward solution.

Someone needs to write some program to make capping from HD a lot easier, sounds very time consuming at the moment.

Thanks for the info about capturing HD Lourdes. It will be probably be years before I can capture HD.
