camcorder video quality?




Michael


Using Adobe premiere, Is there a way to increase video quality, not to HD, but better quality? Also, will replaying the video on the camcorder before putting it into the computer hurt the quality of video when I finally put it in the computer? Also, when video is put threw a USB cord, is that a form of compression?


Answer
"Using Adobe premiere, Is there a way to increase video quality"

Not really - you can play with things like the colour balance, exposure etc but whether you're getting an overall improvement is questionable.

"Also, will replaying the video on the camcorder before putting it into the computer hurt the quality of video when I finally put it in the computer?"

No. If it's a tape based camcorder you'll wear the tape out eventually, but it's not a real problem.

"Also, when video is put threw a USB cord, is that a form of compression?"

Not exactly. If you've got a tape based camcorder the video data has to be streamed - you can't go back and resend the last couple of bytes if your PC missed them because it was busy doing something else. USB isn't good at streaming so tape based camcorders use firewire for the video and mostly just use USB for transferring stills. I say "mostly" because some camcorders have a "USB streaming" mode - it's mainly so that you can use the camcorder as a webcam and it works by compressing the video. Unfortunately that compression lowers the quality and often leads to problems with AV synch when you try and edit the video.

What brand and model(s) camcorder can be used to get this same exact quality video?

Answer
The best Quality Video Camcorder in the Consumer Level Camcorder Market, is a MiniDV tape Camcorder. HD Camcorders, that being any Camcorder storing the Video it shoots to anything but tape, and DSLR cameras, all interpolate the Video. What that means, as the take video and store it on the storage media, they take one frame from the lens, several from the internal electronics within the Camcorder, one frame from the lens, several from the internal electronics within the Camcorder, one frame from the lens, several from the internal electronics within the Camcorder, and so on until the end of your Video.

Looks like this, where lens frames are + and camera made frames are >

+>>>>>>+>>>>>>>+>>>>>>>+>>>>>>+>>>>>>> and so on

The frames made by the HD camcorder internal electronics, not from the lens, are 80% of any HD Camcorder's videos. They are all made using an algorithm based on the frame from the lens before and after these frames. Mostly impossible to edit

Furthermore, you can get a MiniDV tape Camcorder for under $600, to even try to get a HD camcorder that could shoot as good or better Quality Video, you would need to spend $5400 to find one that could.

starting small film company interviewing models need a GREAT hd camcorder under $1000 with close up any ideas?




Juan


Im no professional but would like a camcorder with near professional features and quality i know there are many good ones but i'm on a budget of under $1000 ive been doing research and found a canon vixia hfs20 but it has mixed reviews and i truely want something GREAT thanks for the help


Answer
First, let's define professional camcorder:

Lens filter diameter 70mm or larger.
3CCD or 3CMOS imaging chip system - 1/4" or larger.
XLR audio-in connections.
Records to low compression (HDV, DVCPRO HD or XDCAM/HDCAM) video formats.

When you find a camcorder with the above, all the other stuff like separate manual focus and zoom rings, manual audio control and all the other manual controls on the outside of the camcorder will be included.

You already know that there is no "professional" camera made (new, anyway) that is under $1,000. Since you are doing interviews, I presume that means you get to control the environment - specifically, lighting.

Under good lighting conditions, ANY camcorder can provide good video. You just need to know what that camcorder's requirements are for "good lighting conditions". That leaves low compression applied to the digital video stream and audio.

Audio first. Consumer grade camcorders - if they even have a mic jack - use a 1/8", (3.5mm) stereo plug. Your mic selection will be a bit limited, but the NRG SA-568 and RODE video mic are worthy of investigation. Just because a consumer camcorder has a mic jack does not mean it has manual audio control - so be careful. Download the camcorder's manual form the manufacturer's web site to be sure.

Video compression: AVCHD is a LOT of compression to MTS files. This continues to be a large reason why professionals do not use AVCHD. This is a bigger deal if there is fast action. I can't imagine interviews with models being "fast action".

The Canon HF S series *should* be OK for you IF YOU TURN ON THE LIGHTS so they are bright enough to meet the camcorder's "good lighting" requirements. I prefer the HF S100. Learn about three point lighting and four point lighting. Learn about use of makeup in a HD video environment. high definition video sees EVERYTHING.

That said, given a choice, use of a miniDV tape based camcorder is preferred for a LOT of reasons... The Canon HV40 and Sony HDR-HC9 should be investigated - but only if your computer has a firewire port or you can add one (this is the only way to get the video from the camcorder to the computer for editing).

Answer
Your question does not make sense to me.

A "camcorder" defined:
"A camcorder (video CAMera reCORDER) is an electronic device that combines a video camera and a video recorder into one unit.

In order to differentiate it from other devices that are capable of recording video, like cell phones and compact digital cameras, a camcorder is generally identified as a portable device primarily designed for video capture and recording."
http://en.wikipedia.org/wiki/Camcorder

If you want the "best of the best" then you want a professional grade camcorder. Barring that, you will not be looking at the "best of the best". The step down from professional-grade would be "prosumer". But lets define professional grade, first... In my opinion, pro grade camcorders:
1) have lenses larger than 60mm diameter - usually 72mm.
2) have imaging chips larger than 1/4" - usually 3-chip array and more typically 1/3". Can be 3-CCD or 3-CMOS.
3) have XLR audio-in connectors.
4) record to DV or HDV or some other low-compression format (not AVCHD/MTS).
Deviate from any one of these and the grade of the camcorder drops to "prosumer".

Depending on your specific requirements, those worth investigating:
Sony HDR-FX7, HDR-FX1000, HVR-HD1000, HVR-A1.
Canon GL2

In the higher-end consumer grade area:
Canon HV40, HF and HF S series.
Sony HDR-CX500 series.

No consumer internal hard disc drives camcorders (knowm problems with vibration and altitude prevents recording video). No consumer DVD based camcorders.
