What mid-priced HD camcorder records has best video quality?

Q. I am looking for a mid-priced HD camera (500-600 max) to make shorts to develop my point of view as an aspiring film maker. I am not concerned with sound quality because all I will be focusing on music videos. I realize the more expensive ones would do a better job but considering its a Christmas present I really need it in that price range. Also, what features would be best to look for?

A. There are many great HD camcorders available but not many around your price range (unless you check eBay, craigslist, etc. for used). Check some of the camcorder review websites, like videoguys.com, etc.

Even though you say sound quality is not important, you should consider one with and external mic capability. Many cameras do and/or they are proprietary to function with only they’re same brand mics.


How to use the camera function on my camcorder?
Q. I JUST BOUGHT a Blue Vivitar 508HND - 1080p digital camcorder. I'm a first time user, I've never worked with a camcorder like this before. But I know that 1080p is a really good quality for video and it also has a camera function on there. I wanted to know how can I take a professional looking HD photo with my camcorder?? What would be some good angles to use to get it to come out the right kind of way?

A. "Megapixel count" is a measurement used for digital still images.

Video resolution is measured using horizontal line count.

480 horizontal line = "standard definition" video.

720 or 1080 horizontal lines is "high definition" video.

Using this (the first number represents the number of pixel columns on the imaging chip; we already determined the second number represents the horizontal rows) to get to "megapixel count" results in:

640 x 480 (4:3 aspect ratio standard def video) = 307,200 or almost 1/3 megapixel

1280 x 720 (16:9 aspect ratio high definition video) = 921,600 or almost 1 megapixel

1440 x 1080 (16:9 aspect ratio high definition video) = 1,555,200 or about 1.5 megapixels

1920 x 1080 (16:9 aspect ratio high definition video) = 2,073,600 or about 2 megapixels

The digital still capture section of the image capture device uses the imaging chip very differently from the way the video section of the image capture device uses the imaging chip... And this is only one, of several, ways video "quality" is determined. The compression applied to the video when captured and stored makes a HUGE difference. For example (an extreme one to be sure), a standard definition, low compression, camcorder like a Panasonic AG-DVX100 will capture much better video than a high definition, high compression, video capture device like a cell-phone/smartphone... especially when the playback screen is large.

Lighting, fast action, use of a steadying device and many other factors also contribute to "video quality" or "photo quality".

As for how to take photos with your Vivitar 508 HND - link to the manual:
http://www.vivitar.com/files_products/417/DVR_508_Camera_Manual.pdf
Photo capture starts on page 18.

"Good angles" depends on your requirements and the subject. Camcorders are not designed to capture digital still images - this is a secondary convenience feature. This is similar to using a digital still capture device to capture video - they are not designed for this and video capture is a secondary convenience feature for digital still images. If photos are important, then use a digital still image capture device, not a camcorder.

Since a "professional camera" would be more typically a SLR or dSLR with interchangeable lens system starting in the $2,000 range (including a couple of decent lenses) and this camcorder is none of these, you are setting an unreasonable expectation of the equipment you have.
