General Discussion / Reinsert edited PSX Final Vantasy VII videos
« on: 2009-06-22 13:00:17 »
Hello, folks... I'm here to ask for your help!
I'm from Brazil, and I'm trying translate FFVII PSX to Portuguese Language. ALL THE GAME was already translated, EXCEPT the subtitled videos. Menus, Dialogs, Graphics, Kernel, Minigames, etc, are perfectly translated.
But the translation only will be completed when the original subtitled videos were replaced by our translated and edited videos. We want replace ONLY 2 videos in special, JENOVA_E.MOV - the video that shows Sephiroth talking with Jenova, subtitled, and the last video of the game, the ending scene, I can't remenber the name of the file now, but I'm sure that's a *.MOV, with subtitles too...
JUST ONLY THOSE 2 VIDEOS!
I can convert them to .AVI format, with PSXVideo or PSX Movie Converter, edit them with VirtualDub, and convert them to STR with any STR Converter. But I can't reinsert them back into the ISO. I've been searched around the google, but... I cannot find nothing about this. I talked to jPSXdec author, and he says me:
"Is jPSXdec able to rip ANY video of FFVII PSX perfectly?"
The truth is, because nearly all PSX movie frame-rates fluctuate a little bit, there are no existing converters that can rip FF7 movies "perfectly." 15 FPS is definitely more accurate than 13 FPS, although a frame rate of 15000/1001 might be even more accurate. But even that wouldn't reflect the subtle variations in frame presentation times.
JENOVA_E.MOV, like some other FF7 movies, contains trailing audio after the video has finished. jPSXdec v0.35 assumes audio and video should start and end at about the same time, so that extra 4 seconds of audio is messing up the calculation.
The next version of jPSXdec will have better frame rate calculation. For now, it is very easy to change an AVI's frame rate using other programs (such as VirtualDub).
"And later, when I convert them to STR again, can I reinsert back into the ISO?"
No, jPSXdec cannot currently re-encode or re-insert new movies into games, although I hope it can some day. FF7, like most SquareSoft games, will be extra tricky because it uses some unique movie encoding. While you seem very concerned about frame rates, when jPSXdec is updated to re-insert movies, it probably won't even need the frame rate. As long as the new movie has the same number of frames as the original, the frame rate can be ignored.
As a side note, in the difficult case where someone wants to change the number of frames or frame rate of a movie, then that person will definitely need serious technical and programming skills. Replacing PSX movies can be a very complicated process.
We tried so many times to encode/decode FFVII videos to replace into the ISO, but... We can't!
Can someone help us with this process?
There's any tool to extract the PSX FFVII Videos/Reinsert them back into the ISO?
There's someone that could reinsert a edited video into the PSX FFVII ISO???
Please, help us. It's very, very difficult...
Sorry for any english error... But I hope that you can understand my problem.
Thank you very much.
