So i have been spend along time searching for a way to reduce the file size after being rendered but they all used H264 which doesn't exist even when i go into quicktime as my format. Is there a way to reduce the file size but also maintain the high 1080p 60fps quality for a video? I rendered a video earlier which was only 3 minutes and it had take up about 70gb. Any help?

Have you tried H265 yet?  If you're seeing 70GB with H264, you should get about 60% of that file size (so, 43GB); however, even thought it's a MP4 it won't play back on as many devices as H264 as H265 is not a standard yet.  Also, it's a little tricky to find in Adobe Media Encoder because the Format appears as "HEVC (H265)".

If rendering to QuickTime movie file format, Apple ProRes 422 {Proxy) yields a relatively small file with good image quality.

What is the intentended use for you rendered movies?  Broadcast?  Social Media?  Mobile devices?  More othen than not, the delivery format determines your settings and your files sizes are in keeping with those settings.

For what it's worth, H264 is one of three compression types still supported by Apple for both compression and decompression.  It just hasn't been through QuickTime since 2013.  While the MOV file format is still in use, it's AV Foundation Frameworks now.

to render H.264 you should use Adobe Media Encoder. read about the workflow here:

What Roei said.. Do Not use Quicktime H.264 even if you open an encoder that will render to that format because that flavor of MPEG never worked well in a QT container and Apple stopped development a long time ago.

MP4 is the most universal delivery format and the file sizes and quality is very reasonable using the presets in the Adobe Media Encoder. You should never mess with presets for rendering until you have spend a good deal of time studying video formats and compression because the chances are very high that you will make a mess of things.

Check out Roei's AE Blues channel on YouTube. He's got a pretty decent tutorial on rendering.
