I'm posting this question out of frustration for working on a same darn project for 4 straight days and nights without having much progress. I AM A NEWBIE (didn't even know what codec was up until recently...) and am currently working on authoring a DVD. I began working with Three XviD avi files of each appox. 700mb. Each has the specs of; VIDEO Res: 720 x 304 Fps: 23.976 Bitrate: 1332 kb/s Qf:0.254 bits/pixel AUDIO (FS 48000Hz) Stream1: AC3 448 kb/s (6ch) CBR Stream2: MP3 128 kb/s (64/ch, stereo) CBR Stream3: MP3 128 kb/s (64/ch, stereo) Stream4: MP3 128 kb/s (64/ch, stereo) Stream5: MP3 128 kb/s (64/ch, stereo) Stream6: MP3 128 kb/s (64/ch, stereo) Here are the processes that I have followed so far. 1. Appended all three XviD avi files using VirtualDubMod (Nandub couldn't keep all 6 streams) 2. Demuxed audio, plus extracted'em all as WAV(all 6 streams) just in case. 3. Made direct stream copy of Video(only video) using Nandub (E:\Movie\AppendedXviDAvi.avi) 4. Wrote the avisynth script (to add horizontal strips to video, Resulting 720 x 480) AviSource("E:\Movie\AppendedXviDAvi.avi") BicubicResize(720,304,0,0.5) AddBorders(0, 88, 0, 88) 5. Ran the AVS in QuEnc to create M2V 6. Tried to load the M2V file as an asset in DVD Maestro and it gives an error message. "Invalid Frame Rate" I suupose the Frame rate should be 29.97fps for NTSC.. (Tell me if I'm wrong.) But I'm not sure if that is the main problem, or I goofed somewhere else. The point is.. I don't know what to do to fix it. I looked all over place to figure out what to do, but failed to come up with the answer. I've read the Guide multiple times... HELP!!! Thank you. :thanks:
