    Was the max buffer of 30.000px or mask feather of 1000px upped in CC?

    Dino Muhic

      Hi,

       

      I work a lot for companies doing big media installations (auto motor shows for example) where we have huge resolutions, which often exceed the maximum comp size of 30.000px in width.

       

      Is this limitation still there in CC? And if so, why can't it be set higher? With LED technology getting better the resolutions are skyrocketing (I already worked on 3mm pixel pitch LED panels)

       

      Also something that goes in conjunction with this: Mask Feather size,  which is limited to 1000px in AE CS6 and lower.

      Any change there in CC?

       

      If this limitations would be removed, it would be a good argument for CC.

       

      Thanks in advance

      Dino

          The maximum width for a composition is still 30K pixels. That's huge. I can't imagine the hardware requirements to playback 24 fps video in 30K frames. It's all my system can do to playback 4K frames. I also can't imagine trying to work on a 40 layer 3K comp. You must have some monster computers or your 30,000 pixel wide compositions are not very tall.

           

          Same thing is true for mask feather at 1000 pixels. With 8 bit video and a mask feather of 1000 pixels you are limited to 4 pixel wide banding in the alpha channel. (256 X 4 is just over 1000 pixels) With LED displays running no higher than 8 bit color any wider feather would just give you wider banding in the colors. 

           

          The one and only time I worked on a multi panel display setup requiring more than 4K resolution I did the setup in a 1/4 sized comp, put in my place footage and completed the animation in the 1/4 scale comp. I then split out pre-comps for each section, resized the pre-comps using the scale comp script in AE, then rendered the 8 new scaled up comps. This gave me the flexibility to work quickly and still output a perfectly synced, perfectly sized 8 stream 1080P 30 fps multi panel display video.

            And if so, why can't it be set higher?

             

            Software programs run on hardcore math. Nobody can rewrite 16bit integer code that has evolved over more than a decade overnight and just like Rick, I don't see exactly a reason to be in a hurry. It will be another 10 years before 8k monitors become mainstream and you can stack more than 3 of them side by side to exceed those 30000 pixels. Your use case is quite specific and while it is just as valid as any other, it probably merely presents a tiny fraction of all users. It simply comes once more down to that unless there are enough users actually requiring these features, nobody will spend time and money on such stuff. Will happen one day, of course, but not tomorrow or the day after that...

              That's sad to hear.

               

              The company I'm working for is specialised to work with such high resolutions, as I am for about 5 years.

               

              We had a resolution of about 28.218px * 15.600px for the Volkswagen Beijing Auto Motor Show in 2008.

              I also had a 48.000*720 project 2 years ago and now we have one with about 57.000px*224px

               

              When we have resolutions higher than 30k in width we split them up, but sometimes we would rather like to have them in one comp. The machines could handle it (albeit very slow at full resolution) but the 30k limit makes our work very problematic sometimes.

               

              Since we are workin in 16bit/32float a banding problem is not ocurring when you know how to handle it.

               

              A mask feather on an adjustment layer that is controlling for example exposure on 3D renderings can go higher than 1000px to look good, but here again, we have to make workarounds to achieve certain looks because we are limited by AE here.

               

              Oh and we are working in 50p, not 24p, but the final renderings are getting splitted for the final output in the end.

               

              The 1000px feather and 30.000 buffer limits are artificially set and I wonder why there is no (hidden) option to change it.

                They are not "artificially" or forcibly set, they are inherent in the underlying math.

                  Again, sad to hear but thanks anyway.

                   

                  When you have to animate stuff on over 250 meters of high res LED panels, the technology seems not be there yet unfortunately.

                    Sounds like a case for setting up a workflow like the one I described. Not easy, but doable. In a single comp, with todays systems, not practical to work at full resolution.

                      We have a lot of workflows and tried even more.

                      Working in scaled down comps is not possible because many effects and expressions behave  differently in different comp sizes. Cameras are problematic as well as masks and their feather and expand settings, which I explained above already. If you don't scale the feather up with the comp the result looks different.

                        As the others have already said, the maximum dimensions for a composition and the limit on mask feather haven't changed in After Effects CC (12.0). All changes are listed here, by the way.

                         

                        If you want to lobby for such changes to be made, please submit feature requests here and explain in detail what you need to do that you can't now do:
