I'm trying to figure out how to render my motion graphics files to reasonable sized videos (I'm very new). right now I'm working with a 4 minute basically just an audio visualizer for a song (song is 5mb). When i render it with the quicktime format at 720p at 60% quality I got a 140mb file, which is 65mb after i converted it to .mp4 with media encoder...a lot better, but still seems pretty big to me.
Last night I was watching a tv show online and noticed it was 50 minutes long, .mp4, 160mb, and i don't know what the resolution was but it looked better than my simple video does even though it's 12 times longer and less than 3 times bigger. How can I get that kind of quality and small file size?
