so basically, i made this short pow edit with HD 60FPS go pro footy in after effects. i rendered it for the highest quality, and exported it into a .mov file.. but when i play it, it lags SOO HARD and also, its 20 FUCKING GIGS!! how do i make it smaller without sacrificing resolution!? its too big to upload anywhere! plleeeassseee help!
In an attempt to sound less like a douche and actually try to help your desperate case, you should not edit in after effects, adobe's editing program is Premiere pro. And I'm not too good with compression yet, but you should not export in .mow, it makes the hugest files I think. You need to compress it using another format (I'm pretty sure MPEG is a good option)
Had this problem too. When you check your rendering settings, make sure its not on 'LOSSLESS', this is for when you are going to use it in another edition program etc. afterwards. Pick .mov or whatever will work best for your workflow/end result.
