I noticed some time ago that some CD's of the english Kings Quest VII Windows version v1.65c also have three unused RBT videos in the AVI folder. These are version 4 RBT movies compared to the version 5 RBT movies of the DOS versions of the game. Since they are twice the size of the normal RBT's I rewrote them as version 5 RBT's and noticed that they are 10 FPS (like the AVI's and compared to the 5 FPS of the normal RBT's). I tried them with the english v2.00b DOS Version of the game using DOSBox. But they stuttered unless I used a cycle value of ~20000 which had negative effects during the normal gameplay (distorted sound, firecracke bug).MrPunchy wrote:any way to use the avi videos in KQVII instead of rbt?
The framerate is better in the avi videos.
But now that ScummVM supports SCI32 games I took these 10 FPS RBT's and converted them to AVI's to be used with the english Windows versions of Kings Quest VII. The reason is that these movies have less blocky compression artifacts when the camera moves or changes than the normal AVI's and the audio is also slightly better. The downside is that they are 3 times as big. But with ScummVM this isn't a problem (other than with systems running Win 3.1).
I made two comparison screenshots: Link, Link
From left to right: 10 FPS RBT (converted to AVI), 10 FPS AVI (normal Windows version), 5 FPS RBT (normal DOS version)
Example 1: Frames 264, 265, 266 from Intro, Example 2: Frames 48, 49, 50 from Outro with good ending
Examples scaled up by factor 2 to make the differences more visible.
These are extreme examples since these are parts when the camera moves.
I converted the RBT's mainly for myself. But I thought maybe someone else would also like it...
So I created a patch that patches the normal AVI's of the Windows version to the improved Version: Download
The patch supports the following versions: english 1.51, 1.65c, 2.00b (and maybe 1.4), german 1.51, french 1.65c, spanish 2.00
Latest ScummVM daily build should be used because older builds have problems with some language version/AVI codec combinations.
The improved AVI's can be scaled up by 2 if you switch the "Full" option of the game on. You have to start a game, switch the option on, leave the game to the main menu and then play the intro to make it work. It's the same for the normal AVI's.
The non english versions of the improved AVI's have the same sound as the normal AVI's since I don't have a source with better audio for these languages.
Edit: Exchanged the links to the new AVI's for a link to the mentioned patch to not provide copyrighted files any longer.
