red screen of " absolute" annoyance

Hi ,

fairly this is the 1st time i post here ,i started working in after effect since 3 months ago using version 2017 , but since i was importing some files to help me  in my project "motions text" related i end up facing with the red screen problem , i managed to go around that for my 1st project but after that i upgraded to 2018.3 , and the problem gone for good and  i was a happy till i started importing mp4 files every file turns red in some frames i did every solution i could find but none worked hopefully i managed to go around the problem by cutting that 1 second at the start of the any video i'm exporting but seriously it's starting to be annoying every mp4 file i import turn red...  and i can't go back to use 2017 since most of my project are made using 2018.3..
