    I’m working on a 5K project. Is it ok to work in smaller comp size (1920×1080) and then change comp size on export to 5K? I realise I have to scale up all clip sizes but is this a good working method?

    Ive turned my animation clips to proxies , what else can I do? Is it ok to work in 16 bpc instead of 32 or can I work in 16 bpc but change on render to 32 bpc?

    Thanks for any advice. This is my first big project so Im learning as I go.

    5K’s aspect ratio is 5120 × 2880 and when you stretch the image from 1920 x 1080 to that, it will end up pixelated because for example, a 1080p video works for the 1920 x 1080 aspect ratio. It can fit that size perfectly. If you are trying to render it to a screen of 3 times the size, expect a pixelated image. Its just like if you rendered a smartphone sized quality to 1080, stretching it out does not look as well since it has to extend more pixels to make the screen expand to one screen and it does not look the best in the end. Hope it helps!

    So 4800×2700 is a different ratio to 16:9?

    Just pick an aspect ratio that fits the original.

    The beauty of AE is that there are no limitations other than the size rule of 30K by 30K.

    Now the other rule is the squeeze ratio. Keep that 1:1 at all times.

    So it’s normal to take a larger frame and scale down in your workflow.

    There are however some plug-ins and processes that will task your system due to the constant scaling. In some cases, there are plug-ins that do not support anything over HD.

    Not sure if thats the case of late.

    proxies. they are a thing in AE, too.

    do all your work with the proxies, then turn them off and render at full rez.
