Video Editing Suites - A new requirement

Just passing on information so you know. In the new Pinnacle Liquid Edition 6, a beefy audio subsystem is now a requirement. Folks using the standard chipsets that ship on the mobo, including the new Intel chipset on the 915/925, are having sync issues. This is fixed by adding a Creative Audigy 2 or M-Audio card and using the ASIO subsystem. Granted, Pinnacle coded for it, but I believe that was also done to support audio in HDV.

From now on, I will recommend a Creative card for standard machines and to look at M-Audio for real sound editors (after asking the sound guys at Dvinfo.net).

What do you think?
 
That doesn't surprise me at all. In many cases, the timebase for the video is slaved to the audio, and the (realtime) timebase for the audio is dependent on the timing/clocks of the audio hardware. In the case of onboard mobo audio, much of that is CPU driven, and some of them don't have hardware timers, and instead emulate them, which means that the timebase accuracy is based on the loading of the CPU and the OS'es scheduling. At least that's how I understand it, it seems plausable. All I know is that I had severe irregular-timebase playback problems with some of my recorded clips, when using my Realtek ALC650 onboard audio, but when I switched back to my hardware (Vortex2 PCI) audio card, everything cleared right up, and that's the best theory that I could come up with, knowing the operation of the hardware.

Does that theory seem to align with what you've observed at all?
 
Does it make any difference if I use a hardware encoder i.e. Plextor convertX? BTW, The only pinnacle I've tried was studio7 DV and it blew goats. Liquid is obviously pro of course but Im just sayin' man, I'm just sayin' 😛
 
The encoder already has it in a DV stream as it comes in, which would be like it would from a camera, I believe. So the same deal I suspect.

S7 blew goats? I liked S7. S8 blows goats, which is why I switched to Liquid (plus once S8 touched a S7 project, it could not go back). S9 is cool and uses some of the similar underpinnings as Liquid. But once you get to the big toys, the other stuff is boring. It is kind of like comparing Notepad to Word. 😀
 
ASIO support in Soundstorm is pretty poor. I've always had to revert back to WDM driver mode in Cakewalk. One of the MB's I'm looking at for an upcoming build features Azalia audio onboard, that would be sweet if it had some decent ASIO support, but I know very little about it.
