Movie Maker video loses quality after editing, even when importing and exporting MP4 at 24kbps video bitrate

I am editing raw videos to upload polished ones to Youtube. I am capturing a game with OBS Studio, and the raw video output from OBS Studio is a sharp, high quality mp4. I then load that raw mp4 file into Movie Maker, and edit it by splitting, adding transitions, and a title slate with text. I export the video as an mp4 file using a custom setting (I've also tried using the "for high-definition display" setting as well), as a 1280x720 video with a 24000 kbps bit rate (and 29.97fps). However, the output video is not as crisp, and the colors are muted. I have tried using the maximum bit rate allowed in Movie Maker and this had almost no impact on the video quality or video size. That suggests to me that the problem may be with the importing of the mp4 file, but I can't figure out why it would be doing this. I have uploaded small portions of screen captures from before and after (pre-import and post-"high-quality"-export) to illustrate the quality loss I'm seeing.

Can anybody explain why this might be happening, and, especially, what can be done about it?

    I understand the differences between Windows 7 and Windows 10. That is not my problem here. All of my software is compatible with a 64-bit operating system.

    My video card is new (GeForce 1070 GTX) and the drivers are up to date, so that is not the problem either.

    Window 7 has 32 bit while window 10 has 64 bit, there is a big difference.

    Video card in win 7 is not match to win 10, that is why upgrade is not advisable- not a good choice.

    I did upgrade from Windows 7 to Windows 10 earlier this year, but I don't understand how or why this should make any difference. Shouldn't my Movie Maker version be the same as anyone elses with Windows 10?

    Also as an update, I downloaded a trial of Adobe Premiere Elements and tried a similar process, and I get no video deterioration with that program. So there's clearly no hard rule that a piece of video editing software must reduce the quality of a video clip.

    Movies saved in Movie maker deteriorates the quality of video due to compression and decompression process.

    Upgrade your video display adapter driver and save movie as ... to computer.

    If your computer is an upgrade from previous window version, you will not get good result.
