Why I can't upload my video into Photoshop?

Use Handbrake (a downloadable video conversion app) to open the file and check the codec. If it is not H.264 use the app to convert it.

I don't know what codec means

@Kevin Stohlmeyer h.264? No, I have no clue on what that is and it doesn't have an "h" just a bunch of numbers

@NC344102901jfo check the codec for the MP4 - is it h.264? It may need to be converted from your phone codec to a more accessible one.

Sure, I also deleted Photoshop so I'm pretty sure I do reset my preferences that way (it gave me an option and I clicked "yes." I'll send you multiple

Same thing with AVI, FLV, and MP4. When I did MP3 it became entirely a new picture layer and the video didn't even come through so I think that is maybe because the video is corrupted however with FLV and AVI I was able to access it on my laptop but just not able to get it through Photoshop. I recorded this on my A53 Android phone and then emailed it, then I downloaded it. So I don't get how there is anything wrong. 

Can you post a screenshot of the entire document with the Layers panel expanded and visible? It works on my side, and have you tried resetting preferences that can solve weird problems sometimes.
