You could use VirtualDub to resize the video. Use a script like this:

VirtualDub.Open("D:\\in.avi",0,0);
VirtualDub.audio.SetSource(0);
VirtualDub.audio.SetMode(0);
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.SetDepth(24,24);
VirtualDub.video.SetMode(3);
VirtualDub.video.SetFrameRate(0,1);
VirtualDub.video.SetIVTC(0,0,-1,0);
VirtualDub.video.SetRange(0,0);
VirtualDub.video.SetCompression(0x75796668,0,10000,0);
VirtualDub.video.filters.Clear();
VirtualDub.video.filters.Add("resize");
VirtualDub.video.filters.instance[0].Config(112,64,4);
VirtualDub.video.filters.Add("brightness/contrast");
VirtualDub.video.filters.instance[1].Config(22,20);
VirtualDub.video.filters.Add("unsharp mask (1.3)");
VirtualDub.video.filters.instance[2].Config(5, 30, 0, 0, 0, 0, 0, 0);
VirtualDub.audio.filters.Clear();
VirtualDub.subset.Delete();
VirtualDub.SaveAVI("D:\\112x64.avi");
VirtualDub.Close();

And run "VirtualDub.exe /svdub-convert.vcf /x /r".

BTW: The Script sets "Huffyuf" as the compressor, so the 2 GB
limitation should no longer be a problem.

Read the first Bytes. If the file starts with "RIFF", it's w WAV. You
can use StripHdr.exe (command line prog) from WinDac to strip off the
wav header, or do it yourself in with your GUI program (WAV header is
48(?) bytes).

Bye, Uwe.
