mac and mpeg :(

PeakOutput

so i like macs and ill be getting the 27inch imac pretty soon

BUT

next summer im gonna have to be able to edit, render and burn a 5-10 minute video (standard def) in less then 15 minutes

the best way for me to do this is with vegas(for numerous reasons i wont go into here, i love final cut but for this job vegas is better). this means running windows threw either bootcamp or parralels but i asked this on another forum and got this reply

'One of the issues on the Mac side from I understand is that at the hardware level the Mac's have some of the code disabled on processor to do some of the MPEG decoding and even running Parellels won't help over come that issue.'

can someone explain this to me? they said i can still use vegas threw bootcamp or parallels and it wil work but what affect on the performance and speed of rendering etc will the above have? why does mac do that? are there any solutions besides me having to build a pc?

If you use Parallels/VMware Fusion to run the Windows system then they are not going to get optimum use of the processor for Vegas. Vegas has not been optimised to run in a VM environment.

If you install BootCamp and boot directly into Windows then you should get the native performance that you would expect.

thats what i thought and in his responce he only mentions parallels as not getting around the issue but if its a hardware thing then surely bootcamp dosnt make a difference either?

another person on the same forum who i know to be a well known figure in the audio visual training world simply said ' mac and mpeg = bull**** combination' and i am wondering why exactly

Could be an OS issue?

Smells like bull**** to be honest.

If Mac and mpeg was so bad, how come most film studios rent MacPro's from Apple when doing their video editing.

Something sounds funny here. Run it natively using Boot Camp as one of the guys said. See how it goes.

most film studios arent editing mpegs and to be fair i knew before he said anything that apple wasnt a fan of mpeg

the guy has clarified saying its not hardware nerfed, osx just wont use the extra code on the processor to accelerate its mpeg decoding or something like that but if i use windows threw bootcamp it will take full advantage of it apparently which is excellent news

It's not a case of OS X not using the "extra code" in the processor. Vegas is optimised to use certain hardware, if it doesn't recognise the hardware then the optimisations don't kick in. The issue is not unique to OS X, the same thing happens if you were running a VMware server on PC hardware.

It is unable to take advantage of the virtual machine's resources. In the virtual machine such as Parallels Desktop you could assign 12 processors to the VM if you had 12 processors in your computer, it would make no difference. The reason is that it doesn't recognise the hardware because there are virtual drivers installed - the VM doesn't tell the OS if there is a 3GHz i7 or a 2.5GHz Core2Duo processor available.

If you run Bootcamp, there are no virtual drivers between Vegas and the hardware. It recognises the Intel Core2Duo/i3/i5/i7 processor, the nVidia/ATI graphics chipset and the specific optimisations for that hardware kick in automatically.
