I am working with 5k footage in a 1920/1080 sequence. and then upscale to a 5k sequence when edits finished. My question is do all the contents in the aftereffects composition all so upscale to 5k. All the raw footage is 5k, just worried tho, as when i linked it into aftereffect from premiere it was from a 1920/1080 sequence, so when I then go fit to frame size in premiere is it just stretching in my i920/1080 aftereffects comp to 5k or accessing the original 5k footage. As when i open aftereffects the composition has not changed it composition settings to 5k after I have done this.
Any help / knowledge on this would be much appreciated. cheers
An Ae comp is the size you set it to be. If you have created a 1920x1080 comp in Ae, that's the size it will remain unless you change it. It doesn't matter to Ae that the comp is being used in a 5K sequence.
