I remember when I got my Hi-8 camera and it was 100% stated that it was "broadcast quality". Then I got my Sony digital HD cameras and they were even better! They were 480 x 720 or so and it was thought that it could get no better!
Rod is, of course, 100% correct in his statements. Pilots should think about this using the term "appropriate technology" or "proper tool for the job".
Most budding drone pilots are not going to know how to crop video - that's a step above the normal cutting and assembling. 720 video is actually 1,280×720 which is about one million pixels per frame or 3X the number (density) of what we considered "broadcast" back in 2003.
Back to the tool analogy - these days most of our (at least my) audience looks at the videos on a smart phone, tablet or in a box (like youtube) inside a web page. There is really little (or no) difference in these cases.
If you are a pro or intend to do independent film production - it's another story....but you probably wouldn't have a Phantom in that case...
This is becoming more and more important because we are now seeing 4K being pushed. This will take up MUCH more memory, require more time to edit and assemble and may require you to get a new faster computer to process. It may also result in images which are actually worse....because for a given size of sensor, packing more pixels (dots, picture elements, light receivers) onto it results in less light hitting each one! That's why really good cameras have very large sensors...and it's why Apple uses only an 8MP sensor in their top of the line phones even though they could use one double or more the size. They simply refuse to mislead their customers and provide a worse image by advertising megapixels.
On the same subject, the lower resolution is still photos from the Phantom are more than fine also....will save you some disk and memory space. But the penalty is not as great as it is with the video, so using large is fine too! |
