Need to make a looping animation for a 10 Hour video

[Saif5C48]

Hello Everyone, 

I am kind of lost on what direction to go. I basically want to do long nature videos. I already have 10 hour audio (that part is taken care of). But I want to make a cool animation that loops for the entire 10 hours. Basically a 10-20 secs animation that loops 10 hours. 

I am trying to figure out how to marry this animation with audio in the most efficient way without losing audio quality.

1) I can make a 10 sec animation in After Effects, but where exactly can I join my 10 hour audio with the looping animation? 

2) Is the most efficient way is to make a GIF? And somehow combine with audio somewhere, but will I lose visual quality? And where to combine GIF to 10 hour audio?

Below is an example of someone doing a 10 hour with a looped animation, is that a GIF:

Any help would be great.

For a serious use case nobody would bother fusing audio and video. That's what synced media players/ playback devices are for that can handle timecodes and multiple streams. And for such an ambience piece just 10 or 20 seconds of animation is usually way too short. the repetitions become easily apparent after only a few loops and then you turn it of or don't bother. On the other hand of course just creating a long clip for YouTube is a case of "whatever works", but this is nothing you would do in Ae. If at all, you'd render one hour of footage and then assemble it elsewhere, even YouTube's own Studio tools in a pinch. However, in such a case you shouldn't fall in love with both audio and image quality. There is definitely going be some re-comnpression on the server that is beyond your control and it most definitely will mess with some of that stuff.

Thanks for reply. 

But for long videos like 10 hours, there is no option but to loop and that's what most do on youtube. The main focus is audio, the loop animation is just a visual backdrop. 

I cannot find a software where I can loop a video long enough till the audio ends (10 hours). And copy/pasting is not ideal at all. 

I was hoping After Effects can somehow do it. Anyone know where I can merge long audio with a looped animation?
