View Full Version : Problems when encoding Starship Troopers PAL

Hello, this is my first post and I hope I don't get flamed right away :)

I have done some rips with older versions of Gordian Knot & NanDub where it was necessary to manually launch the second pass and where I had to encode the audio separately. These all went fine. (I didn't use any special settings for the second pass btw).

Today I tried Starship Troopers PAL, a 2-sided DVD with the new GK 0.21beta. The first side was finished in ~2:40 mins without any interaction which is very nice but there are some problems with the avi.

My settings were the following:
I made a d2v with the DVD2AVI shipped with GK, it said it's interlaced, I didn't see any interlacing though therefore I didn't do any deinterlacing. I set Audio to 160 kbit VBR and AVI file size to 1 CD for the first side of the DVD. The resulting bitrate is 1547 kbit, framerate 25 FPS of course, bits/pixel*frame = 0.281, output resolution 640x352 and I did crop "Pixel" so that the aspect ratio matches the 1.818 ratio for 640x352 exactly.
All other options I let at the default and let it encode with sharp bicubic resizing, no field operations and no noise filter (the DVD source didn't seem very noisy to me, I have seen much worse).

Audio & video encoding went fine but now I have some problems with the avi, namely:

Parts of the letters from the intro have some distortions, eg when it says "TOUCHSTONE PICTURES and TRISTAR PICTURES" at the beginning in white letters on a black background then the bottom right part of the "U" from "TOUCHSTONE" seems to be upside down (white being there where there should be black and vice versa). The are a few more scenes with letters where there are similar problems.
I have seen problems like this in other rips from other persons before and I wonder why this happens and what can be done about it?

There is a second problem about 26 mins into the movie (where they stand in the queue waiting for their meal), it's a scene with rather low motion which becomes a scene with very high motion for a brief moment without any cutting and when the fast motion begins all the parts that are moving are distortet.

Can anything be done against this (in an easy way without having to manually analyze where to put keyframes and things like that...)?

That's a shit problem, try to use antishit (you'll need to do Full Recompression, not Fast Recompression). I guess you won't be able to use GordianKnot for this, as GordianKnot doesn't support Full Recompression...

Hi - to be honest - i've no idea why you have these errors in your encoding.

I've searched my profiledirectory and these were my nandub (also PAL version) settings for side A:


VirtualDub.video.SetDivX(1320,10,100);
VirtualDub.video.SetMotionDetection(8,10,300,240);
VirtualDub.video.SetCrispness(30,1);
VirtualDub.video.SpaceKF(24);
VirtualDub.video.InternalSCD(90);
VirtualDub.video.SetMinKBPS(460);
VirtualDub.video.SetPredictive("D:\\starship2.stats",23,3,270,3000,14849,250);
VirtualDub.video.SetLumaCorrection(1,10,5);
VirtualDub.video.SetCompLevelsMain(2,6);
VirtualDub.video.SetCompLevelsA(300,3,16);
VirtualDub.video.SetCompLevelsB(300,4,16);
VirtualDub.video.SetCompLevelsC(300,5,16);
VirtualDub.video.SetCompLevelsD(300,6,16);
VirtualDub.video.SetCompLevelsE(300,7,16);
VirtualDub.video.SetBitsReservoir(3,40,30,90,45,0);
VirtualDub.video.NoAVIOutput(0);
VirtualDub.video.GenStats(0);
VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[0].SetClipping(10,10,7,15);
VirtualDub.video.filters.instance[0].Config(640,352,3);

I agree to WEF - try divx4 and the avisynth method

i have had a similar problem with"crouching tiger,hidden dragon".
The scene where the girl and the teacher are fighting in the trees
with a lot of fine green texture.the bitrate can't handle the motion.
thats about the size of it.

And again solution is: Use DivX 4 codec
