Problems converting cut scenes from UMD's...

Pwolf, everything works great. The important thing is I was able to extract the video in avi format.

However, I'm trouble extracting the audio from the files. Were you able to hear anything from the file you had worked with?

I was in the middle of writing a psp conversion guide till pwolf beat me to it.

Damn my laziness...

Actually, I could still use a little help if your interested. The converter Pwolf told me about works okay, but it can't seem to convert the most important movie file without messing up. Was Lande's converter made to convert movies over 200 mb and over 24 minutes long? Because all I end up with is an 8 gig file that can't be read after the 2~3 minute mark. It converts the entire movie but the movie contains so many errors that it's virtually impossible to watch the entire thing. No program I have reads the movie after a certain point.

The best I was able to do to fix this was use a file splitting program to convert the movie in parts. (That took all day to do) By splitting the file, I was able to better separate the corrupted frames from the good ones. Of course this wasn't the perfect solution. By the time I was done with this, I was left with only half of the footage from the OVA. I might have to wait for an updated version of Lande's program to be released before I can successfully and easilly convert this.

Or perhaps the guide you were working on could help me out? If your interested, I could send you the file I'm trying to convert. If you can convert this enitre OVA without getting any errors during the conversion process, you trully are good. Because I'm stumped....again.

btw, I've just got to say, the quality of these cut scenes on this game are trully incredible. I think the quality might even surpass the quality of anime on most dvd's. I was comparing some of the footage from this OVA to some G Gundam episodes I have on DVD and the quality of the OVA puts the gundam episodes to shame. I'm trully impressed with that. Especially considering the fact that it was only formatted to play on a much smaller screen.

(I thought that by increasing the aspect ratio's of a video by several times what it's supposed to be, the quality would take a dive. Guess not)

The video is H.264, but it was wrapped in an MPEG-2 Transport Stream; whether or not that's what causes the errors on the computer I don't know.

To get the video stream out losslessly, you can use mplayer to dump it to a raw file and then use MP4Box to mux it into MP4. However, Lande's conversion program produced less errors than doing it that way, so there's definitely something effed up about the file. mplayer can also dump the audio stream, but like I say in the next paragraph, you're probably going to be SOL on that one.

To dump the stuff with mplayer, just use this on the commandline:

mplayer "filepath" -dumpvideo

That will dump it in mplayer's folder. Just replace the .dump extension with .264 and MP4Box can handle it from there. Similarly, dumping the audio just requires replacing '-dumpvideo' with '-dumpaudio'.

The audio is in ATRAC3 format, which means that there's not much of a chance of converting it unless you 1) have something that works with MiniDiscs and on top of that, can convert these things to WAV, which is hard in itself because ATRAC3 is inherently encrypted or 2) record it via line-in while the PSP is playing it and try to sync it to the video in VirtualDub or Premiere or whatever else.

Thanks a lot for the suggestions Qyot27. I'll be sure to try this out tonight when I get home. I'm realy happy you decided to share your knowledge in regards to the audio issue I was having. That all makes sense now. Fortunately, extracting and converting the audio is more of an extra bonus for me. It's not completely neccessary.

Hopefully this alternate method for converting the video stream will work a little better. I'll let you know how it all turns out either later on today or tommorrow. Once again, thank you very much.

I'm sorry Qyot27, but when it comes to using any programs that require use of any command line languages, I'm a complete noob. Could you just tell me what program I need to even type these commands in?

The guide says I need "a working development environment that can compile programs.
On popular Linux distributions, this means having the glibc development
package(s) installed."

If you could just tell me how or what to do here, I'm almost positive that I can handle the rest. I just need to know where to start typing these commands because I think the guide they offer assumes your already supposed to know this much.

Command prompt on win xp works.

Ok. But what I'd like to know is how do I access it? I have no clue how to access command prompt. Is command prompt the the black window you can access by typing in "cmd" in the run application from the start menu? Because if that's not the command prompt window I haven't got a clue what is.
