Hello all! I tried searching the forums here and didn't find an answer to my question. I am trying to convert MKV files that are 1080p (1920x1080) into .MP4 to be used on my Apple TV 2. I have a 1080p 54" Panasonic TV. I have been using the ATV2 setting and noticed that it changes the output size to: 1280x720 Picture quality is excellent but was wondering if it was worth using the High Profile setting as it keeps the output to 1920x1080 Would I notice a difference? Would it just take longer to encode? Any pointing into a direction would be appreciated.
