Hi everyone
Having bought the Vegas 4.0+DVD bundle a week ago, and having been doodling with it since then, after reading the manuals - yes, I went to the trouble of printing the whole several hundreds of pages of them - I've come across several problems that have prevented me from using the program as I'd expected to do since I tried the demo version.
I must say I send a query to support last monday, but till now have had none but an automated mmessage, which makes me a bit unhappy with it.
But lets stop with the genral complaining and lets go to business:
My setup uses a 2.4 Ghz Intel Pentium IV processer, has 1 Gb Ram, the HD are all 7.200 rpm, I do capture with a matrox 2500 in PAL DV mode, with upper field first (strange as that may seem).
The DV avi files open without any problem - till now - and so do the wav PCM 48.0 16
bits files.
I tried to produce a DVDA PAL video stream only to which I wanted to join, in DVDA, a 448 kbps ac3 file with the soundtrack.
The video render was ok (though it did show some weird occasional white line discontinuities when the cam did a sidewise upwards move - specially in a scene where there was a strong contrast betweem a black tuxedo and the white shirt underneath) which was - i think - more noticeable when the file was rendered at 9 Mps than when I redid it at a lower speed (an experiment in video encoding quality)
I wanted to produce an dolby digital ac3 file with the soundtrack, so I could joint the two in DVDA.
Something very strange happened:
the sound file was corrupted, with plenty of pops and crackles, and with the sound disappearing altogether during the song intermitently (it's a small file with a singer).
I recoded it at various rates, stereo and 5.1, to no avail... always the same problem.
Is it because the source file is originally mono - a file made from an old 40's movie musical - though recorded in DV into two tracks, in stereo mode (the only accepted sound capture format)? what can I do to solve this?
The weird/interesting thing is that, when rendered the same DV file with DVD PAL, using 384 kbps bitrate instead of the default 192, the resulting file previewed in DVDA as it should, "flawlessly" (with the same proviso about those white discontinuies)... but I think DVD PAL records sound in mpeg sound, not dolby sound, or am I wrong?
Or is there any correspondence in quality between the bitrates in dolby AC3 and the mpeg sound encoder (which allows a max bitrate of 384 bps, while files in ac3 for DVDA can go as high as 448 bps).
I'm totally stuck in this, and since the dolby encoder was one of the main - if not the main - reason for me buying the VV+DVD bundle, you can I think understand my frustation.
Hoping to hear from any of you guys, yours friendly

PS - Got another problem, in another area, will explain it in a different post.
