Removing pixels from Game footage?

Yorae · Post by **Yorae** » Thu Sep 22, 2005 3:16 am

I ripped the movie files from my PS2 DvD by exploring the disc and dragging the movie files onto my desktop. The file extensions for the movies were .DSI and I changed that to mpeg so I could view them. I can only view the files through Windows Media Player and Ulead. Virtual Dub and VLC can't view them, even if I change the extension to AVI.

Now the problem is that when I play the files the movies are all jerky in the sense that the scenes keep on freezing throughout the clip. Also, when I try to edit the clips on Ulead I get all these pixels and corrupted parts which make the footage pretty useless.

My question is if there is a way to "clean up" the clips and remove all the unwatnted junk from the frames. (I read Absolute Destiny's Guide but couldn't find a lead to what I should do)

Suggestions, anyone?

From Bauzi:
This is very interessting... I didn´t thought, that you can get PS2 footage on that way too...
OK how do you changed them into mpeg? And how is the ressolution? You can maybe kill the pixels, by decreasing the fileressolution... Thats all I know now!
Maybe your PC is not "good" enough for these videofiles. How strong is your system? And wich game was it XD ?

To change the files to mpeg, I simply renamed the file and changed the extention to .mpeg instead of .DSI

The game is Uzumaki Naruto Ninden ^^ It has some pretty cool 3D animation cut scenes. I don't think that my system is the problem, because I was able to rip FFX and X-2 footage and several other DvDs before and the scenes played pretty nicely.

Hmmm... I haven't tried changing the resolution. I'll try doing that and will tell you what I get^^ Thanks for replying ^^

You didn't change the files to mpegs, it sounds like they were already MPEG-2 files, and you just renamed them to ".mpg" so that your software would recognize them as MPEG-2 files.

You need the proper utilities to convert the video to an AVI. Simply renaming something ".avi" doesn't "convert" it to an AVI.

Read the guides on the site.

Try River Past Video Cleaner! This schould work!
Well it´s shareware, but who cares, if you know were you have to look for

Maybe it has a protection in the Video, so some programms can´t handle with it... You could also try to convert them with the little help of "SnagIt".

Thanks for the tips, guys. I read the "using game footage" guide and followed Castor Troy's guide to rip the movies from the game DvD. I was able to get the file as I mentioned before, and I know how to convert the to avi's.
The problem is the pixalated footage. I tried using River Past but it didn't do me any good. Also, I tried the footage on three different computers and the results were the same.

Here are some shots of what my footage looks like:

The typical files size I have is 36 Mb with a data rate of 4096 kbps and a frame rate of 29.970. I wonder if that has to do with the problem

From Bauzi:
It could really be the framerate! Some systems and programms have problems with it! (That´s the same thing when I rip dvds.... I have 3 different programs, because of this) However use a different framerate (25, 30, well not 15

) and when this doesn´t work use other fileformats such as mpeg or even wmv (I don´t know if wmv works in your editing programm) or use an other video codec for avi files!

Incorrect framerates don't cause incorrect frame decoding. Sheesh.

The errors in the frames you captured are probably artifacts you'd see from a damaged file. As you just ripped it, and the video is presumably playable on the PS2, this is unlikely.

Possibly the decryption (if any) is incorrect, or the format is wrong. As jbone pointed out, changing the file extension does NOT change the file format.

Another cause of this is incorrect decoding: I've seen similar artifacts playing back unindexed MPEG-2s in a decoder that expects to be passed an indexed file.

Your best option would be to research the DSI file format and figure out what it is similar to. As there do exist programs that can handle it as it were some MPEG elementary video stream (presumably MPEG-2), it's probably pretty close -- maybe a few things different here and there.

Something else you can try is passing the file through DGIndex and loading up the resulting index file via AVISynth, just like any other VOB.

If this doesn't make sense, read EADFAG, and it will.

well i think its protected.
i have the game, i'll try and check later, what i can do with it

From Bauzi:
I swear! Different framerate causes problems with ripped files and other things in my system and some of my programms!
