Yeah I mean scaling is a process. Is the line above the sequence red or yellow when you scale to 50% in a 1080 timeline?

What version of Premiere are you using? It's strange that that is happening. Maybe Adobe would have some suggestions.

My conclusion is that for a 10% or less crop for stabilization, its totally worth it to just edit in 4K. If you're zooming in 50% it's a good idea to work in a 1080 timeline.

​No, the first one (with the girl) had no effects on either. The second one has MB Film on both.

​I completely agree. It was just merely out of curiosity that I wanted to run that test.

Here is with Magic Bullet Film added. Both render times were the same.

Add contrast, etc?

Check it out. It's not a ton of difference, but you can definitely tell the HD timeline render is sharper. These are zoomed in 400%.

​Ahh okay, I thought only AMD cards had Open CL.

​I was curious about this myself. I just did a test and it looks like zooming in 200% on a 4K timeline/rendering at 1080 is softer than keeping 4K footage 100% on a 1080 timeline.

I'm pretty sure the issue here is that the Intel Graphics do not have CUDA. Therefore Mercury Playback is not going to technically work.

I tried both out on Premiere CC, and they both run the same speeds. What kind of graphics card to you have? Are you using Mercury Playback?

Interesting. Fell under the radar. Internal 4:2:2. Built in NDs...

​No details, but how soon might we except the "new" stuff?

​Moire even at 4K?

​Me too.

The reason alot of people use a 1080 timeline is because that is the delivery dimensions. If you're working with graphics, or any other footage mixed in that is 1080, or if you are wanting to crop in 2x on 4K. If you're going to only be using 4K footage with no 2x crop, then yeah a 4K timeline is smooth in Premiere.

​I'm also curious to see how the 18-35 E-M5II combo looks. I'm thinking about selling my Panasonic 12-35 f2.8 and buying an E-M5II.

It just goes to show that personal rankings vary from person to person.

​Have you tried switching your shutter dial to the top? It's much harder to accidentally move it when it's on top instead of the back.

​The brand is Zotac.

I found a semi-inexpensive fix. The new GTX 960 graphics cards can run up to three 4k monitors at 60Hz. They're $200 so I just went ahead and upgraded.

Okay, a bit of bad news. The second P2715Q does daisychain via Displayport from the first monitor at 60Hz, however it's only mirrored. I had to run the second monitor via HDMI which only runs 30Hz. I've set the second display up as my Program monitor only, so I won't ever notice a difference, but if you are wanting smooth 60Hz on the second monitor you'll need a second Displayport output from your computer.

If you are doing mostly handheld work go with the Panasonic 12-35 f2.8. If you can use a tripod, monopod, or any other stabilizer I'd highly recommend the Sigma 18-35. It's definitely my favorite lens.
