QuickSync and Skylake i7-6700K
 
Im building a new PC.
Is it worth to wait a little and buy i7-6700K or stay beter at 4790K?

Does Edius support quicksync on Skylake i7-6700K?

What motherboard?

I'm sure it does. If you're willing to be an early adopter, go for it.
However, I would wait and see how it fleshes out. I'm not particularly happy with the boards that I've seen released. Chipset capabilities vs actual deployment is disappointing. The support for the M2 chips could be problematic because of how it shares.
This will also depend on your particular needs.

If you go for it, please report back.

Since E8 relies heavily on QS for video playback it would be useful to learn more about Skylake's Quick sync capabilities. Yet benchmarks seem to care little about QS encoding/decoding quality and speed. So until someone directly compares E8 on 6700K and 4790K it is difficult to judge what benefits are in waiting vs getting a new previous generation processor now. Anyway, I'd be inclined to wait a little ...

Meanwhile pure CPU based x264 video encoding benchmark indicate nearly 8% speed increase over the previous generation processor.

I wouldn't say that E8 uses QS 'heavily' for playback. It is more of an assist. I can see 1 extra layer in 4K projects using AVC based files.
I really don't see that much of a boost in HD settings. I'm guessing that my overclock has to do with that. Users with lower powered systems will see more of a boost....especially laptop users.

Well in that case I'd be "heavily" interested in using that 1 extra 4K video layer in E8 :)

My thinking was that there has to be a potential to accelerate editing with QS significantly otherwise why would the team behind Edius put effort in this at the time when 4k@25p (and especially 4k@50p) camcorders starting to hit the market? Or are they specifically targeting the market of lower powered portable systems? Yes the reasoning was based on pure speculation that E8 might gain more from QS playback/encoding with next subsequent processor generation. Anyways I'm ready to accept whatever they bring to the table - even if QS works as an assist that results in 1 extra 4K video layer.

Great deal of prosumer DSLRs and camcorders sold in near future will have some sort of 4K@25/30p (or even 4K@50/60p) recording modes and there are plenty of reasons to use those modes, provided we can edit them efficiently.

Where I get 3 layers of 4k I get 5 layers of HQX.
Until there are user reports on Skylake we won't
know what it brings to the table.

You could end up paying a lot of money for something that's not that much better than the last thing.

If you don't mind paying for marginal improvements, then go for the new SL CPU. If you want something good, cheaper and is already known to work brilliantly with Edius, then go for the 4790K.

The final factor in making a decision may simply be down to cost v performance. The difference in cost between two systems can be quite substantial, and if the benchmarks flying round the web are anything to believe, then that cost diffrence may only equate to a 10 percent boost, at best.

If the cost of updating, replacing or simply building a new system, gave you a 30 to 50 percent increase in processing. Then I could personally see the point to it. But without even knowing the QS performance, which is unlikely to be that much better or could even be problematic within Edius. It may be best to go with the 4790K.

The old story, a small 5% improvement costing $2000 could be worth it if that 5% results in more than $2000 more net revenue over the life cycle of the equipment.

That what business cases are supposed to sort out.
For talking purposes, assume a job a week, or 50 per year at $1000 per job.
If with the mod one can do 5% or 2.5 more jobs per year, that amounts to $2500, OK!

I guess Skylake QS "isn't working" completely in E8 since Skylake will require actual Intel drivers. In EDIUS QS export is not working with "actual" drivers for a long time now, E8 didn't solve this issue yet.
Only playback acceleration seems to work.

If you like QS export you have to use the Pegasys x264 Plugin that also supports QS as renderer. Pegasys TMPGEnc also works with the current Intel drivers.
You can't install the plugin in E8, you have to install E7 and copy the plugin to the E8 plugin folder. Maybe they fix the installer at Pegasys, maybe not.
Hope GV fixes the QS bug, I already started a thread about that here...

But honestly, since the 4770 Haswell we didn't see a real performance improvement from Intel. Even 4770 wouldn't be interesting without the gain in the QS engine over the 3770...

TMPGE releases the plugin for each version of Edius. You will have to wait until they release TMPGE Movie AVC plugin for Edius 8. It will be a paid download.
