Hello
I'm trying to import an .mp4 file but I get this error:
"file is damaged or unsupported"
File is OK, so anybody can help me? Thank you
Where did you get the file? The particular format may be unsupported. Try converting it to a production codec. Highly compressed sources are never a good choice for compositing. I even convert Sony XD Cam or footage from a Canon DSLR to something more friendly. You can use QT any number of programs to convert (transcode) your original to a more friendly codec like Apple ProRez, Black Magic, Motion JPEG, or a ton of others.
Here's some more detail about what Szalam said about the trial version:
