Sofdec MPEG1 video stream with wrong colours...
I've been ripping the MPEG streams from the Sonic Heroes (PC) SFD movie files.
For the uninformed: Sega and a few other game companies use a video file format whose extension is SFD (Sofdec). These are containers that have a regular MPEG1 video stream and a particular sound format known as ADX that can be easily converted to WAV. I've successfully ripped 12 video streams (using TMPGEnc Plus 2.5) but the other 10 seem to be screwed up (they show the wrong colours and appear more blocky). I know the files aren't corrupt because when I run the videos within the game they appear fine. Here's an image of one of the screwed up streams: And here's a rapidshare link in case somebody can help me figure out how to rip the stream correctly: http://rapidshare.de/files/35018742/..._Team_Rose.rar ---3MB The SFD files can be perfectly viewed with VLC (videolan). |

You can use VLC to save them, under stream settings when you open a file (not quick open). Actually, it'd probably be better to use mencoder to rip it to a lossless format, and then encode from there, since vlc doesn't offer lossless and isn't very high quality when it streams.

I tried DGIndex and Avisynth. This was the result:

But it's still screwed. I don't know some videos are working differently.... Here's how it should look like: Last edited by Zhelkus; 1st October 2006 at 03:38. |

Hi!

Just guessing here, but at least part of the problem appears to be the header indicating an image size of 320x448, while your "good image" is at 320x240... Last edited by setarip_old; 1st October 2006 at 05:23. |

I tried editing the sequence header of the MPEG stream to 240 from 448.
(i.e. 00 00 01 B3 14 01 C0 C4 to 00 00 01 B3 14 00 F0 C4 ) Didn't help. Very strange problem. Let us know if you find a solution. -Nic |

I thought you meant it actually played okay in VLC, which it definitely doesn't. Huh, weird signalling in the file. I'd submit it to ffmpeg along with a link to this thread (for the sample and extra info): http://ffmpeg.mplayerhq.hu/mailinglists.html They should be able to tell what's going wrong and fix it, eventually.
Oh, and the file is mirrored on my server in case you need to give anyone an alternate link, for those who can't do the rapidshare thing: http://foxyshadis.slightlydark.com/r...S_Team_Rose.7z Last edited by foxyshadis; 1st October 2006 at 15:07. |

Are the 10 problematic files from the same disc as the 12 good ones, or are these all from 22 different discs?
If they are from different discs, perhaps the problematic ones incorporate some type of conversion template or mask that is different than that of the good ones... Despite what you've said, would you be good enough to post the header information from a "good" file? |

Nope, they're all from the same disc. Gimme 20 minutes and I'll upload a "good SFD" for you guys to see.
Thx for the help so far guys EDIT: Ok, here it is. http://rapidshare.de/files/35126841/...atross_End.rar --8MB I think I should've done this sooner. Anyhow, the header or the part where they show all the info I displayed in the snapshot is the same. Thanks for the suggestion, foxyshadis. I think I'll do just that.

The information might appear different but in the end it's still the same because I tried copying this info (from a GOOD SPD) into the other one (the BAD SPD) and the stream turned out the same. Quote:

The FFMPEG mailing lists aren't very helpful when it comes to asking for very technical issues. It seems my situation is proof of it. |

Another question - What stream information is generated by VLC for the "good" output and for the "problematic" output? Please post the screencaps for each...
And - rather than presuming that using VLC to convert a "problematic" file won't be good (because of what you saw in a screencap), it might be worthwhile to try one such conversion... |
