I've started Youtubing recently and I noticed that my videos take an eternity to upload (anywhere from 3 hours for 15 minute videos to 5 hours for 25 minute videos). Apparently, I'm rendering my videos in the wrong codec, but the right container (my videos are MP4 files, as YouTube recommends). However, it recommends I use a H.264 Video codec, and I have no idea to render my video as such. Any advice or tips on how to do so? Thanks in advance.
