Film is HD. If you go to see a movie in the theater, most likely is film being projected on the wall. The movie will never look any better than
that. DVDs, Blu-Rays, or even a vhs tapes are versions of the movie that have been compressed so that they take up much less space than the original
film master. A digital version of a two-hour film would take up roughly a terabyte of space on a hard drive without some sort of compression. On
larger media, less compression is necessary and more detail from the original film master is preserved.
Digital HD video cameras were introduced more recently - they do not use film. Older cameras would not record in HD because there was no cheap media
available to the public to take advantage of it (large file size) and no one had TVs that could display that kind detail anyway.
If you use a camera that records to actual film, the picture is as good as it could possibly look - beyond high definition.
Don't you recall the race for digital cameras manufacturers to have higher megapixel count? Have you ever heard anyone use megapixels to refer to a
traditional film camera? Nope, because film cameras produce pictures that are already as good as they can be.
