De-interlacing Gran Turismo 3 (GT3) PS2 video

Man I’ve put this little project off for a long time – I’ve ripped the GT3 PSS video files onto my HDD in the summer and, until now, I couldn’t find a good way to de-interlace the video…
 
Anyway, now that I’ve found a way to de-interlace the video in real time, here’s a quick summary of what you gotta do:
1 – Rip the MPEG stream from your PS2 DVD onto your HDD (using something like Extractor (link) ).
(1.1 – Rename the extension from .mpg to .pss ? – I can’t remember… It was such a long time since I ripped the video…)
2 – Demux the PSS file to get a M2V and WAV file (using something like PSS Demux (link) ).
3 – Use ffdshow to feed the video into AviSynth to "do the de-interlacing magic" in real time (using well… ffdshow (link) and AviSynth (link) )!!!
 
I’m not gonna go through step 1 and 2 blow by blow, as the only thing that’s difficult about it is to scan the DVD for MPG streams (using Extractor), and then pretty much a 3 month old baby can do step 2 (which, only involves dragging the PSS file into PSS Demux).
 
Anyway, before I go to step 3 and begin the fun of using ffdshow with AviSynth, if you play the PSS file, you’d get something like this:
 
Frame 486 - Interlaced
 
Yup, that’s right – the top half is one field and the bottom half is another field…
 
So, step 3:
3.1 – Load up ffdshow
3.2 – Create a new profile
3.3 – Check (enable) the "Avisynth" filter and enter the following:
top = Crop(0,0,width,height/2)
bottom = Crop(0,height/2,width,height/2)
Interleave(bottom, top)
AssumeFieldBased.Weave
LoadPlugin("C:Program FilesAviSynthpluginsLeak KernelDeintLeakKernelDeint.dll")
LeakKernelDeint(0, 5, true, true, true, false, false, 0)
Note that I used "Leak KernelDeint" (link) instead of the normal "KernelDeint" as it offers me better optimizations.
 
Now when you play your video with the newly created profile, you should get something like this:
 
Frame 486 - De-interlaced
 
The reason why I used ffdshow in step 3 is so that I can create 1 profile and use that across different videos if necessary, plus it’s easier to tweak in real time if you needed to…
 
 
Actually, if you watch the video, you would have noticed that the first 2263 frames (or so) are progressive (non-interlaced) frames and then the video "change mode" from then on to two-way interlaced (i.e. 1 interlaced frame contains information for previous and next frame).
 
Below is a screen cap of frame 2297:
 
Frame 2297 - Interlaced
 
You can clearly see this two-way interlacing on the blue "GT" text and on top of the wheel arch – and this is where the "two-way" feature of the de-interlacer comes in.
 
Below shows this same frame but totally (minus the de-interlacing artifacts…) de-interlaced:
 
Frame 2297 - De-interlaced
 
But yeah, I guess they really shouldn’t have mixed interlaced material with progressive materials in the same video file in the first place…

There’s a much better solution in a later blog entry that deinterlaces sans artifacts Wink :

Though I have to warn you, the file size is kinda big…
 
Still, it’s nice to get quality stuff!
 

Evanescence – The Open Door (review)

Alright, forget about what I said previously – yes the album sounds awful when you first listen to it, but once you’ve gotten used to the weird way in which the wonderful choruses are joint together (and the crappy endings of the songs…), what you are left with are one of the usual Evanescence goodness – excellent choruses.
 
However, that’s not the say the album is good – it’s still way below expectation (considering I liked almost every single song on "Fallen"…) but I’m just saying there are a few songs on there that are good.  So here they are:
• 03 – Weight of the World <– Only the chorus though… the rest of the song is crap…
• 04 – Lithium
• 05 – Cloud Nine
• 06 – Snow White Queen
• 07 – Lacrymosa

If you are going to get some songs off the album, below are the ones I find OK as a whole:
• 04 – Lithium
• 07 – Lacrymosa
 
I mean, there are other songs with good choruses but the rest of the song… well, it just isn’t up to scratch:
• 05 – Cloud Nine <– Almost made it into my "OK" category… if it wasn’t for the horrible start of the song…
• 06 – Snow White Queen
• 13 – Good Enough <– Only the first minute of the song though…  It is a really beautiful start but the rest is un-inspiring…
 
Actually, for those of you who are interested, apparently, the first minute of "Good Enough" was originally written for the movie "The Chronicles of Narnia" (link), however, according to Wikipedia, the director rejected it as it was "too dark and epic".

Ok, please, someone tell me the one leaked onto the net wasn’t the real deal (please read my previous post here)…
 
I mean…  I dunno, I’m sorry, but the new album (assuming the leaked version is indeed the real deal) is… well… awful!
 
I have to say, the album’s style was so urm… "unexpected" (and not in a good way…) that I kept asking myself "what the hell are they doing!?" – yes, it was that bad…
 
They should have stuck to what worked and not try to fix what’s not broken  …
