I’ll have a go – I’ve not noticed a pattern to when it happens so I’ll just have to try that next time it occurs.

Thanks tho!

Nope, just on the timeline. I’ve not had any problems delivering films – apart from the challenge of sound mixing with a system that adjusts the volume at will!

[Alex Bond]

It’s the output to the speakers, usually when there are more than one or two tracks in play – it’s really odd!

Apologies, I didn’t realise this thread was getting responses – I thought I’d checked the ’email me’ button but apparently not.

Ok, so it’s an iMac Pro (2017) as below.

From what I am reading on the subject it appears that Adobe are not supporting multi core processors so if you buy a faster processor machine but with less cores it can conceivably be faster than a multi core iMac pro. Given that many manufacturers are favouring the multi core option this doesn’t seem to be a great feature.

I’ve not added more details because I’ve not noticed huge improvements on anything. Though timeline seems faster in some aspects, as soon as I add a colour grade to 4K footage it won’t play at all in full resolution.

Warp stabiliser takes the same time as an older mid-2011 i7 machine and exporting to pro res files actually took LESS time on an old MacBook Pro.

I am seeing reports that Adobe does not support multi core machines – if this is true then the iMac pro is a pointless buy. If FCPX can support then I will be switching to that. Or selling the iMac pro. As it is I’m down 6k and not impressed with Apple or Adobe…

I’m getting the same speeds exporting films on the iMac as I am on an old laptop.

Same conditions, same project, same footage.

[Alex Bond]

Yep, that’s right. When using Premiere you cannot use the iMac pro as an all in one machine (are you listening Apple?) my solution was to tether my OLD iMac to the iMac pro and use the old one as a monitor (so the new 5k monitor is pointless) – this way I can export what I’m seeing on the old iMac and that pretty much resembles what I’m seeing within premiere.

Premiere does not allow you to change the colour space of its Program Window (whatever you set your iMac’s colour to, premiere will ignore in that window – clever? Not really).

So hopefully you have another monitor kicking around or another iMac and the space to set it up next to your new iMac pro.

Ta-dah!…

[Alex Bond]

Oh and in terms of performance – for some reason Generating Peak Audio files takes just as long with an iMac Pro. Which is annoying…

[Alex Bond]

It’s a colour space issue apparently, one that is more apparent as the new iMac screen is ‘better’ than the old one. You can see the shift on any type of export though I’m told it’s actually what the file is viewed on afterwards rather than Premiere.

The Pro is about 10 time faster at exporting most files than the old iMac I was using (2011 high spec) – oddly short 30-50 second films are not faster to export though, which is annoying!

[Alex Bond]

Yes, Quicktime but then the Files are washed out when sent to Vimeo.

I have never had this issue before.
