animan Posted February 12, 2015 Author Share Posted February 12, 2015 Add contrast, etc?uhm, maybe just drop a bit of compound blur on the exact same clip on two timelines, i sized my 4k timeline to about 110% to take scaling out of the picture and the 1080 one at 50, and check the render times..

Axel Posted February 12, 2015 Share Posted February 12, 2015 Nothing against an occasionally necessary stabilization in post. But only for 5 % of the footage at the most. Affordable gimbals are in the world, and abusing 4k for 'reframing' is detestable. Watch this:http://vimeo.com/111900328 Link to comment Share on other sites More sharing options...
AaronChicago Posted February 12, 2015 Share Posted February 12, 2015 Here is with Magic Bullet Film added. Both render times were the same. Link to comment Share on other sites More sharing options...

animan Posted February 12, 2015 Author Share Posted February 12, 2015 I think the softness youre seeing may be related to the MB Film plugin settings somehow.. Link to comment Share on other sites More sharing options...
AaronChicago Posted February 12, 2015 Share Posted February 12, 2015 I think the softness youre seeing may be related to the MB Film plugin settings somehow..No, the first one (with the girl) had no effects on either. The second one has MB Film on both. Link to comment Share on other sites More sharing options...
AaronChicago Posted February 12, 2015 Share Posted February 12, 2015 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. Link to comment Share on other sites More sharing options...
animan Posted February 12, 2015 Author Share Posted February 12, 2015 hmm, my conclusion is still whatever youre planning to do you should edit in 4K! But im curious about other ppls experiences and im still curious about the filmconvert / magic bullet looks / compound blur render test as those 3 were ones i happened to notice worked dramatically faster for me in 4k, I also found some like twixtor had the same performance in both Link to comment Share on other sites More sharing options...
AaronChicago Posted February 12, 2015 Share Posted February 12, 2015 What version of Premiere are you using? It's strange that that is happening. Maybe Adobe would have some suggestions. Link to comment Share on other sites More sharing options...
animan Posted February 12, 2015 Author Share Posted February 12, 2015 CC 2014.. I do still believe that the programme finds it easier to do a lot of things when youre working in a sequence that fits the size of the source material Link to comment Share on other sites More sharing options...
AaronChicago Posted February 12, 2015 Share Posted February 12, 2015 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? Link to comment Share on other sites More sharing options...
animan Posted February 12, 2015 Author Share Posted February 12, 2015 hmm not just that though, i also scaled the 4k timeline clip a little before render as mentioned to take it out of the equation when i was checking the speeds.. (line is yellow, youd need a very old machine to have to render a scale i guess!) Link to comment Share on other sites More sharing options...
Boone Posted June 3, 2015 Share Posted June 3, 2015 I have a similar question. I have a timeline ttyat is 75% 4k footage, 25% HD (GH4 96fps). My destination is HD. Should I also work in a 4k timeline and scale up my 1080 or the opposite, work in 1080 and downscale the 4k?Also, if anyone can clear up a workflow issue it would be a huge help. In the above project I have nested and warp stabalized various 4k clips. The edit is complete and now I need to send to Resolve to grade. When I export as is the nesting and scaling messes it up when they come back into Premiere—the 4k clips are scaled to 50% of 1080, not 50% of 4k.Do I need to undo all speed, scaling, and warping in a duplicate timeline, send to Resolve, then reapply when to are back in Premiere?

You will see noticeable loss of quality due to the first upscale. It is claearly stated in many threads on the Adobe forums that scaling is one of the most time consuming processes, so it is no surprise that working in a 4K timeline is faster and renders faster."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."Again, placing 4K footage in a 1080p timeline is doing a "natural" crop, interpreting pixel to pixel without any scaling, which means less processes to deal with and likely a better result (Premieres scaling is not bad, but still is a reinterpretation which may or may not introduce quality loss in the final footage). Also when scaling during delivery (final encoding) ticking "Render at maximum quality" is supposed to make that scaling more accurate. "Render at maximum depth" only concerns the usage of 10 bit or 12 bit colour space source material and downconverting it to 8 bit for delivery.

hmcindie Posted June 3, 2015 Share Posted June 3, 2015 Guys, you know the "use maximum render settins" option in Premiere output?It will actually ADD sharpening even when you don't scale. So if your timeline is HD and you render out HD, it will still add sharpening noticeably. When you click that setting off, no sharpening is added. But then the scaling itself is a bit worse. Decisions, decisions.If you don't do any scaling, I'd suggest never clicking that option on. If you do, keep it on. Link to comment Share on other sites More sharing options...
