1080p HDTV
You may know that 1080i refers to 1080 lines of vertical resolution interlaced. This means that instead of 30 frames a second, the TV displays 60 fields per second, where each field contains alternate lines of the picture. Because the fields are refreshed so quickly, your brain interprets the signal as 30 full frames per second.
720p means 720 vertical lines of progressive scan video where every frame of the signal is displayed in its entirety, giving a higher-quality, film-like appearance to the picture.
Most HDTVs or HDTV-ready TVs support either 720p or both 1080i and 720p, very few support 1080p HDTV. Part of the reason for this is that very few broadcasters want to broadcast 1080p signals. The reason for that is that 1080p requires significantly higher bandwidth than either 1080i or 720p. And for broadcasters, bandwidth is a precious commodity. Using up more bandwidth for one signal means that there is less room for other channels. So in many cases, opting for a 1080p signal would mean dropping or degrading other channels.
Is 1080p HDTV important? Well, yes and no. Not all video footage benefits greatly from progressive scan. Sports broadcasts and action movies look better at 720p than 1080i because there is lots of fast movement and the interlacing in 1080i is sometimes noticeable, reducing the quality of the picture. Movies and TV shows where there is not a great deal of fast action look better at 1080i than 720p because the higher resolution has a greater impact on quality than the progressive scan, which has little effect where there is only a small difference in the image between frames.
So, while 1080p HDTV is the best of both worlds, the cost in terms of bandwidth, is very high compared to the benefit for most people most of the time.
Good Quality Video Camera for Web Series?
Hey there,
I'm thinking about starting a web series on YouTube with a video camera. I'm no expert when it comes to this field, but I'm looking for a good quality camera that records in full 1080p HD. Since it's just a web series, it doesn't have to be hollywood-quality, and I don't really want to spend a fortune (not anything above $500). Just something worth the price...
Can anyone recommend a video camera/camcorder?
Thanks!

Should I buy a Canon 5D mark II, 60D, T2i, T3i or T1i for video shooting?
I'm trying to decide which of those 5 cameras to buy. This is my first time buying a DSLR so I want one that would be easy to use, but not keep me limited to some cool features. I'll will primarily use it for shooting video. here are some thing I would like it to have
- Full 1080p HD
- 24, 30 and 60 fps
-external microphone "IN" terminal
-good video in low light (so that would mean a wide aperture on the lens keeping the light when it zooms in and out)
I'll like to shoot fast action scenes, slow-motion (so it'll be better a camera with 60fps) and choppy but detailed video (higher shutter speed).
But I'll also like to take photos with built in filters like miniature effect,black & white, fish-eye effect, etc (so that I won't buy lots of lenses).
I also have some questions, since this is my first time buying a DSLR.
-Is mega pixels specifically for taking photos, and does the number of mega pixels effect the video quality, even tho it says full 1080p HD?
-Which camera has a better battery for filming or should I buy another battery pack?
-Which one already has a good built in mic?
-Do they all come with there own Lens or is it just the body?
-If they don't come with there own lens, which lens should I buy for my kind of videos?
I want it to be affordable, after all this is going to be my first DSLR so the cheaper the better, but still not limiting my options. Thanks. :)

Saving a standard video as an HD file?
What happens if you record a video with a standard camera (not HD), then put the video in Sony Vegas and save the file as 720p of 1080p HD.. does it improve the quality of the video, or does it take up unnecessary space as the quality is limited to what the original recording was?
