I will make this simple for you.
There is every advantage to using MPE hardware and no disdavantage. Go for it if you can.
Now about your workflow.
If you can use your native footage to edit ...do so ...in a matched Sequence. ( ie dont transcode before editing)
The advantages will be in your CC and FX work and it gives you more flexibilty when you do need to transcode.
Hi, thank you for your speedy reply.
Sounds good with the MPE, that gives me another question which I will come back to.
I'm still a little unclear about when MPE can speed things up.
If I do as you say and import and edit the 1080p footage directly into Premiere and edit it together and then colour correct etc., I understand that MPE can help a great deal then, a Youtube video I saw was absolutely stunning, it was display four colour corrected 1080p streams at once!
Once I have saved my final project and then want to recode it into PAL standard def can the MPE help again then or is it back to a CPU grind?
I will give another simple answer because I dont actually track the speed advantages of MPE in various encodes.
Others do and it is well published in the forum
For me... MPE speeds up the edit process so so much that I changed my edit workflow significantly because of it.
eg. traditionally its usual to edit first and apply fx and cc last so as to avoid the render bar before playback routine.. I kind of stick to that as an idea but will often do a Key screen, FX and CC as I go now. All due to realtime of MPE on multiple layers.
Yes ...I get advantges when encoding ... (they fly through)... but I never have measured or compared to non MPE .
I do know there is more advantage in some CODEC than others.
Question - "what will you do with the time that you save"?
The CUDA processing features of the Mercury Playback Engine accelerate these things:
- some effects
- blending modes
The acceleration of scaling matters a lot if you're converting something from one frame size to another---which it seems that you'll be doing. And, as Craig suggested, the acceleration of effects makes a lot of difference for things like color correction.
There are details about what is accelerated on this page and in the pages pointed to in the comments on that page.
