hi, i just bought an EOS 600D which according to Canon friends does well with video. i'd like to know the real difference between a 720p and 1080p output via Adobe Premiere for editing?
the video is planned for a student classroom viewing on a wide 40-inch plasma tv. i like to create a clear 10-minute documentary.
please advise. thanks!
1920x1080 IF the TV handles it, some 40" plasma sets are likely only 1280x720 though. See what the sets specs are. Maybe it is full 1080 but it very well might be 720. I know a lot of makers had been pumping out the sub 46" sets mostly as lower end models and many only had 1280x720 pixels on them.
Even though ATSC's TrueHD 1080 is 1080i not 1080p many of the sets can actually handle signals as much as 1920x1080p60 so while TV broadcasts are limited to 1920x1080i60 if you just hook a computer up to the set to play back the video you might be able to get 1920x1080p60. As I said many of the sub 46" sets were made cheaply though and are not as capable of various things though.
Even for 1080i, if you just compare 720p to 1080i channels, despite all of the talk of lower motion resolution for 1080i, to most people the 1080i channels generally end up looking noticeably sharper overall. Then again LCD have such bad motion handling that might be a fair test. Plasma handles motion better so maybe on plasma or CRT sets it becomes a tougher call depending upon the footage (I'd still think that most footage has enough static stuff going on that 1080i would look sharper overall unless you footage is all major motion non-stop).
