I had this version of Premiere and it deleted media and projects on me, some I cant get back.
Why am I still being charged when the update was so catastrophic?

So After Effects uses very little GPU and hardly uses CPU.
So does it ever finish rendering anything?

It’s taken Adobe two years since they surveyed the user base regarding After Effects performance and it’s still not fixed.

Gee it’s become very costly to beta test these days…$50 a month!

Fast forward to mid 2016 and it’s still the same.
Adobe have taken full fare off users for this delivered software that has very poor render performance.

It’s not good enough. Resolve uses 75-80% of CPU when rendering final outputs.

Blending is broken in Premiere because of support for CUDA.
This is an attempt to fix it and doesn’t work properly.
You get all sorts of issues.

Why don’t they just fix what’s broken?
No other app has various ways of blending images – there is only one way – the correct way.

These issues have been around since CUDA was implemented and it’s still broken 3 years later.

It’s not good enough for a professional video application.

Sorry Chris but that is not correct.
Thunderbolt on Mac it’s own drivers and the first versions had bugs that caused the Mac to crash with certain hardware.

This was fixed via an OSX update, which might cause the issue reported.

But Thunderbolt in not PCie.

Hi Jeff

Can you turn off the GPU (go to software Mercury Engine) and retest?

[Paul King]

DVE one camera (pip)or both for side by side monitors.

I dont understand why that should impact H.264 encoding which is independent of Apple QT.

BTW – I found a speed boost from the GTX Titan, even for H.264 encoding.

The more threads you have the greater amount of ram you want to manage this otherwise you lose allot of the power of the Dual Xeon. This does not just have an effect in AE because you assign ram per thread. You just have more control there because of that.

I have 64GB of RAM and that still doesn’t make a difference to multithreadedness in certain CODECs. Would this mean I need 128GB?

If you turn the Core Parking off in the registry then that will stop the OS control on this.

This is not the reason Premiere doesn’t use all CPU cores when rendering. It is CODEC dependent. H.264 is bad at multithreading while MPEG2 is good. My 3D software is great at using 100% CPU. All these results are with Core Parking on.

Hi Tomas

The most recent models of Areca cards are now just LSI cards with Areca’s front end.
Having said that, Areca do have an engineering level in their card BIOS, it’s accessed with a difference password to the default ‘0000’.
In that BIOS there are extra settings relating to video performance. However a lot of these relate to the use of the card in OEM applications for video SANs.

With Davinci, you’re usually only accessing one clip at a time so these extra settings wont really help. They are about stream count and read ahead performance.

With the Areca’s it’s best to just use the default settings and you’ll get the best all round performance for a DAS workstation.
Video applications have a bit of everything in them from a usage perspective, large sequential read, random sequential read, image sequences etc, so no one setting will help.
