Why are my videos exporting so big (3GB!)

I was recommended Camtasia by someone who makes videos very similar to what I want to do. The program is amazing, but I have a BIG problem with the size my videos are coming out. My video is 4 hours long, and it comes out as 3GB. The person mentioned who also makes videos with Camtasia has a 4 hour video as well that is only 413MB! I really need my video to be that size. I don't know what I'm doing differently, I haven't messed with the settings or anything, and our videos are exactly the same (screen-recording with some mp3 music added. nothing much). I attached an imagine of both our videos' info.

Click Share, Local File, Custom Production Wizard, Next, MP4, Next, Select  Video Settings  tab,
Try 60% ( or more or less ), Then continue on.  ( Also find out what your friends settings are. ) 
There are many factors that cause the Finished MP4 to be different sizes. Number of cuts, how many of everything that could be different from 1 persons project to another persons project.
( Experiment with the settings and see what your results are with size and quality. ).

I don't see "Custom Production Wizard". When I click Share, then Local File, this is what comes up (first image), and second image is what comes up when I click on Options. It was originally set to 30,000 kbits/sec, and I believe 60 keyframe rate.I tried lowering that to 1,410 kbits/sec, and 30 keyframe rate to experiment. I haven't exported it yet, but it's taking a very long time. I assume that's a good indication the file will still be large. I'm not sure what else is ok to move around besides those two options. 

The person is not really my friend, it's someone with a popular platform that I hardly expect a response from when I message them. They did reply yesterday with this though, when I sent them a brief message about my videos coming out as 3GB and if they did anything special to have smaller videos "you have to play around with the customize option. I also had the same problem and I had to change it so that the video size are smaller."

In addition to what Bob offered, I cannot help but to note that for the humongous file, there is an entry for "Color Profile" while there isn't one for the smaller file. It would seem to make logical sense to me that if perhaps the larger video was using some specific color scheme or something that it may account for some of the size difference.

I thought that may have been because some info sometimes gets lost when it's downloaded from the internet vs my raw file. Though again, I did not do anything very differently. Just downloaded Camtasia, and went straight to record and export. Our videos are screen-recordings of us doing the same thing in photoshop, so no difference at all in color scheme. As I told Bob, the person offered this response when I asked them why their videos are much smaller "you have to play around with the customize option. I also had the same problem and I had to change it so that the video size are smaller."

Have you examined your different Mac setups? Because one thought I had was if indeed this was related to color depth, perhaps the Mac that achieved the smaller file was configured differently than the one you are using.

Another thought occurs to try. Take that smaller file, play it, and record it playing on your own computer. Then render it out and see if you achieve either a massive file size or if the size is similar to what the original size of the video was.

You might also consider contacting TechSmith support and report it as an issue.

Sorry Elsa, I did Not notice you are on a MAC, My direction was for a PC.
However, finding out what your friends setup is with the smaller file size still would be a good idea.
