Re: Using VirtualDub to improve your AMV conversions.
 

Hi tadad1, thanks for posting the results.In my opinion if u have atlest 10GB disk space we can convert without any compression.Since I dont have so much free disk space I have to compromise with the quality of the video by going for Xvid AVI compression.
By the way how much time did it take for the coversion of ur file?

prasanna, You should also try some of the other compression codecs that still reduce the output size I later tried Huffyuv and Indeo Video codecs and they about halved the size of the output and the final AMV was better quality.

It seems the time it takes depends on the compression codec used with the example the longest took about 14 minutes the shortest about 8 minutes. I can do a full lenght movie with no compression in between 17 to 20 minutes depending on the lenght of the movie.

Hi tadad1,
I have a doubt....does virtual dub converts VOB files or we need to first convert them to AVI and then use Virtual dub.
B'coz I have lot of DVDs i want them to convert them.
Presently I use DVD decrypter to copy the files in to the drive and then use pocketdivxencoder or other to convert them to AVI and them convert them to AMV.

prasanna

prasanna, no VirtualDub does not convert .vob files.
I finally bought a copy of Slysoft CloneDVDMobile and DVD43 which rips a full movie to avi in about 30 minutes. Was well worth the 40 US dollars.

Thanks in advance

I use a program called xmpeg to convert my vob file(s) into a 128x128 avi file, which I can then use amv convertor on....i get pretty good audio and video quality with it.....can actually get watchable dvds on my chi-pod now

Have I to change the options for 1,5" LCD (iPod Nano Clone)?
Please let me know in what way.

This thread is really helpful :D

k.r.i.s.s.i,
For 1.5 LCD you need to change the Resize Filter setting to 128x96 for widescreen or 128x128 for full screen.
If you are going to use 128x128 you need to crop more of the sides as well otherwise the picture will become to compressed and the image will be tall and thin.
Here are some settings I use for 128x128. Copy them into notepad and save. Then rename the file 128x128.vcf. then you can load the settings into VirtualDub by pressing CTRL+L on your keyboard


VirtualDub.audio.SetSource(1);
VirtualDub.audio.SetMode(1);
VirtualDub.audio.SetInterleave(1,500,1,0,0);
VirtualDub.audio.SetClipMode(1,1);
VirtualDub.audio.SetConversion(0,0,0,0,0);
VirtualDub.audio.SetVolume();
VirtualDub.audio.SetCompression();
VirtualDub.audio.EnableFilterGraph(0);
VirtualDub.video.SetInputFormat(0);
VirtualDub.video.SetOutputFormat(7);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetFrameRate(0,1);
VirtualDub.video.SetTargetFrameRate(100000,10000);
VirtualDub.video.SetIVTC(0,0,-1,0);
VirtualDub.video.SetCompression();
VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[0].SetClipping(35,0,35,0);
VirtualDub.video.filters.instance[0].Config(128,128,6);
VirtualDub.video.filters.Add("deinterlace");
VirtualDub.video.filters.instance[1].Config(0);
VirtualDub.video.filters.Add("HSV adjust");
VirtualDub.video.filters.instance[2].Config(0,91776,0);
VirtualDub.video.filters.Add("brightness/contrast");
VirtualDub.video.filters.instance[3].Config(0,20);
VirtualDub.video.filters.Add("sharpen");
VirtualDub.video.filters.instance[4].Config(15);
VirtualDub.audio.filters.Clear();


You may need to adjust the cropping as this is set for a wide screen movie with black bands top and bottom but notice how much I have cropped from the sides.

Hope this helps.

Re: Using VirtualDub to improve your AMV conversions.
 

If you set it to compress the video with XviD at maximum quality, the filesize will be vastly decreased with no visible quality loss :)

The AMV format is very inefficient. Compressing with .rar reduces file size by about 30%. By comparison, an xvid is reduced by less than .1%

Thanks Man
