Make video loop seamlessly using an Adobe After Effects project

Hello.

We have already created a short video using Adobe After Effects CC which can be viewed here: http://35.214.105.2
It's the black and white skyline background at the top of the page with the white logos appearing on top of it.

Task 1: Make loop seamless.
- If you look very carefully you will notice that the sequence does not loop smoothly.
- The .AEP file is fully layered and requires an experienced user to manipulate and extend the runtime by two or three seconds ensuring that the sequence ends precisely where is started.
- The end result will make it is impossible to spot the join when it is looped using HTML5.

Task 2: Output two versions
- The project is 1920x1080 and we need a HD version.
- We also need a cinematic version which is likely to be about half the height (for the website).
- Supply the new .AEP files

I'd be available to work with the editor via Skype to ensure we get it perfect first time.
If this one works we may have others that need looping in a similar way in the near future.

Thanks!
