Low Camcorders
Is the quality of video from Full HD Camcorders still lower than DVCs?
Nowadays you have full HD camcorders that are supposed to deliver best picture. So are the NEW camcorders not delivering as good picture as DVCs.
By DVC I meant digital video cassettes. So I was not too far off the terminology end. But what is interesting is that most brands are now just focusing on HDD and flash camcorders and not MiniDVs anymore.
I agree with Iridflare.
But you need to consider what is “best”. And the assumption is you are referring to miniDV tape (“digital video cassette” is a bit generic).
In video, generally speaking, less compression of the digital video stream is *WAY* better than lots of compression.
As well, the way a video format handles groups of frames can have a substantial impact on video quality.
Last, for this short discussion, anyway, you should learn a bit about the different video formats available.
Since you referred to “Full HD”, you should know that this is a not a technical term. It is a marketing term. While it is accurate to say the “progressive” capture method has some advantages over interlaced capture, the fact is that anything over 480 horizontal lines of video is considered high definition – in consumer cams, that is usually 720 or 1080. Red and Silicon Imaging have been doing Ultra-high definition for a while.
Next, add the video compression layer. The easiest observable method is to understand the data rate of the video. Higher data rate means less compression is used. More compression means more discarded data so lower data rate. Higher is better. DV and HDV (typically captured to miniDV tape; but there are a few ways to use flash memory and special external storage devices) are clocked at 25 mbps. XDCAM, HDCAM, DVCAM, DVCPRO and DVCPRO HD have a similar data rate. Typically, consumer grade camcorders using non-tape storage top out at about 17mbps – though there are a few at the higher end that get to 24 mbps in the AVCHD/MTS file environment. The new Canon XF series camcorder record to an interesting MXF format and delivers 50mbps data stream – but is clearly not a consumer cam.
You can do your own research on GOP and how poorly AVCHD handles video with fast action in the event of a dropped frame.
BUT, it is all about skill. Someone with a good, trained eye can capture good, compelling, content on the least expensive camcorder… while someone with no skill would likely capture garbage with the best available equipment.
