Encoding... (Will edit this post soon!)
EDIT: Wow... It's a game for a profy encoder! I did everything like
Video Dumping guide says, started the dumping without any compression... At the middle of the movie I got a massage that WaveFileWriter is not opened. Turned out that I got low space on local disk C :-)
I interrupted the dumping. All the parts, which were recorded (9 parts, each was 30 secs long), had a quality like a TV with no signal (lots of colorful rays).
I did the same again, but, instead of dumping frames and audio, captured the movie with Fraps! During the recording, my framerate wasn't below 40 FPS. As a result, I got a 14 min movie with very slow picture and sound (like I was recording with 20 FPS). I don't know why!! I have enough strong GPU for emulating games like that (HIS Radeon R9 270) and drivers are installed.
Anyway, your TAS is perfect! I can upload my Fraps capture if you want :-)
