Hello! I've just got my 550d, and i made a little tester video and have just finished editing it in Final Cut Pro. However, when i first exported the project, there were black bars on the side of the video, which i thought was odd. The video had been 'squished inwards' because when compared side by side to teh orignal footage it was asif it had been squished into a smaller space, creating the black bars at the side of the video. After wondering around in FCP, I simply went into aspect ratio under motion, and changed the aspect ratio to 0 (it was set to 6.67) and voila, correct 16:9 video again. EDIT: And now, when played fullscreen on my 16:9 monitor, there are small black bars on the top and bottom of the video? arggg whats going on Why was it set like this? Can i change it? or will it be like this all the time? Its annoying having to change it for every clip! And i was shooting in 720p60 and 1080p24 if anyone is wondering. Thankyou all!
