Movie compiling error during export. Need assistance

Hello guys, i have posted here before recently regarding a movie compiling error while exporting my animation, there are a number of issues with movies playing in the exported versions, both swf and mp4 versions, I get the same 3 error warning messages but i am having trouble locating them individually or whats causing them. It is quite dissapointing as i spent several months putting this together and even with the frequest test viewings during that time and also for the animatic versions i had no issues whatsoever, only right at the end once the sketch had been fully animated. I have a few screenshots of the errors messages as well as the output message, which im also quite unfamiliar with as I am still quite new to the programme. I think some of the errors may be camera related, but im not sure. The movie plays just fine on the main timeline, does this mean that the errors are fixable? Any help would be much appreciated guys, thanks.
