I have an .mp4 file I want to edit in FCP7 that's a rip of a movie and the format is h.264 and 1280x544. In MPEG Streamclip I converted it to prores and chose 1280x720. Is this correct or should I have chosen 1280x544? Is there any reason not to choose the original format?
I also did a test and converted a portion of the 1280x544 movie to 1280x720 because I wanted to see how different it would look but it's identical to the original. If I convert the 1280x544 video to 1280x720 why isn't the aspect ratio different? Shouldn't it be stretched vertically? 1280x544 has an aspect ratio of 2.35:1 and 1280x720 is 1.78:1 so why does it look the same?
I can't tell you why it doesn't look different, but I can tell you that FCP only works with 1280x720 (or 960x720 anamorphic)...so you need to keep it that aspect ratio if you are going to work with FCP. And you need to convert it to ProRes....FCP doesn't work with MP4 well. Tons of potential issues.
