How to fix black and white mp4 files?

Problem:
Whenever I play an mp4 file from my computer, the appearance of the video is black and white. However, not all mp4 files from my computer do that. It seems like the video files I have created specially from Windows Movie Maker are black and white because videos that I have taken from a video recorder don't seem to be black and white. I also have video files that have been converted from VCR tapes to mp4 files and those are in black and white. Even when I'm on Youtube the video is black and white. I clicked on a video, here;'s the link to it if you want to see what kind of video it is (ღ Kawaii Radio | Happy Music to Study/Relax「24/7�| Kawaii Music LiveStream ☆*( ≧o≦ )o:*☆ - YouTube) and the image of the video is just Japanese anime girls, but when I play other videos that are recorded with a camera or are anime videos, those videos are not in black and white.

Solutions that I have already tried:
I have updated the drive, it is called AMD Radeon HD 8400. I just did this by going to control panel ---> device manager ----> display adaptors
After updating the drive, I restarted my computer and when I played an mp4 video again, it was still in black and white. I was thinking of disconnecting the drive and then connecting it again, but I have no idea if that is going to affect my files because I have a lot of important pictures and videos on my computer.

Additional Notes:

• Sometimes, when I play an mp4 file or that video on Youtube, it would be colorful for a split second and then it would be back to monochrome
• There has been a recent update with my Windows 10, but the files were still fine after the update
• Steam has been recently downloaded on my computer
• When I play my mp4 video on another computer (I used my USB to check it out), the pictures moving in the slideshow is actually colorful, but the mp4 files are still in black and white
• The windows movie maker is actually not original. I re-downloaded it after the update has deleted movie maker. Since I have heard that movie maker is no longer available since last January, I redownloaded it from another site. Still, my mp4 files are still in black and white
• Only videos that were saved as an mp4 from movie maker, videos that have been converted from VCR tapes and that one video on Youtube were in black and white.

It could be codec related. Have you tried any alternative video player like Videolan (VLC) or Media Player Classic (inside K-Lite Codec Pack)?

I have tried another app called Movies and TV but my videos are still in black and white. However, I did not use Videolan or Media Player Classic. Those apps are not installed on my computer.

VLC/Video LAN is not part of Windows and usually not included by the builder of the computer. It is free and quite good with a wide variety of media files. Haven't try Media Player Classic, usually having classic in a program's name signifies it may not be from Microsoft such as OE Classic [Outlook Express Classic], Classic Shell [start menu], etc.

So should I download VLC/Video Lan? Is that going to help?

Plays in color for me. It does seem to be a codec mismatch, and trying to download that video gets me a .TS file. These are usually Mpeg-2 encoded. I have the 'Microsoft MPEG-2 Extension' installed from the Store, which may explain why I can play it...

Microsoft MPEG-2 Extension

If it is a codec mismatch, then what should I try? Should I install 'Microsoft MPEG-2 Extension'?

VLC uses it's own codecs and does not rely on any codecs in Windows. VLC can play virtually anything, but installing it won't help other players because the VLC's codecs are just for use in VLC.

Installing the 'Microsoft MPEG-2 Extension' adds more codecs to Window for all apps to use. Your Movies and TV may be able to play your videos properly with it installed. I would try that first.

It didn’t work. I installed it and my slideshow videos that I made from movie maker are stil in Black and white. What’s an alternative solution?
