Without info about the actual video file this is not much use, but this sounds like a decode or cache issue, so start by flushing your disk caches and make sure the file isn't damaged.
You might also considering updating to the latest version of AE. You're on 14.0 and the latest version is 14.1
Any video used will have the same issue so not codec related. I have used PRO RES, H264 mov and mp4. I have deleted the cache and this has not helped. I have also used the same files on existing projects and they are fine and cause no issue.
I was considering that as a last resort incase it is something else that can be done.
Are you still facing crashing issues? Please let us know if you still need help.
