First HDD MPEG4 Video Camcorder
An anonymous reader submits "This is a few weeks old but we have to talk about
this. Samsung introduced the world first hard disk drive based camcorder so you don't have to buy those MiniDV, Hi8s, and DVD-Rs. You take pictures, play MP3s, PAL+NTSC video! The picture quality is 350K so not a replacement for digital camera. The downside is the HDD size is 1.5 Gig so you can record video just over an hour! Why can't these bozos let us put a 40gig 2.5 IDE drive and let us record continuously for 25+ hours! Is there a corporate conspiracy to limit recording time of camcorder to about an hour (like DVD-R camcorders)?"
This is the first? hmm... it reminds me a lot of the Hitachi MP-EG1 that I used a bit in the late 90's. It recorded full MPEG-1 video to its hard drive. (Although you only got about 20 mins as the hard drive was 260mb!)
As a general rule atleast, you won't find mpeg compression on tape; although it could be done. As a general paradigm with tape every frame has all the information to generate the entire image. But mpeg compresses across frames (I know I'm simplifying the process). So if you take one of these tapes and stick it in a player and push play you'ld find it rewinding all over the place trying to grab enough information to play from where you left off. Yes I am aware that DV also uses compression but not across frames. Every image is compressed discreetly. And I'm also aware that dvds compress across frames. But again that is a different scenario.
Also remember 8mm tapes aren't designed to store digital video the same way DV is. You really should not be using them for archive purpose and expect them to be in a reasonable state when you check in on them in a few years time. Ofcourse they work but there is a reason you get a price break buying them instead of a dv cam.
