DVL-Digest 606 - Postings: Index pd150 and gy-dv500 image quali - (2) Slightly OT-CD copy - (2) pd150 and gy-dv500 image quali - "Perry" Stefan P. Glut posted: >My leanings take me to the dv500 for a whole host of reasons, but is the image on the pd150 "better" in any way? Does HAD technology on 1/3" chips, or a new DSP in the pd150, out perform the 1/2" chips and DSP in the JVC?< My understanding is that the JVC uses Sony CCD chips which will probably be HyperHAD. HAD is the type of semiconductor construction used, Hyper refers to the use of micro-lenses for each pixel. Both features improve sensitivity. Ultimately you have to make your own choice. Although I don't own a DV500 I have used one a lot and been delighted with the results. The only reservation I have had with the camera have been centred on the 'Color Matrix' which give what I think is a pretty gaudy picture. If you switch it off, the picture is a little desaturated and unfortunately there is not an independent 'saturation' control. I'm currently testing a VX2000 which also looks good but ultimately a good big one will always beat a good littl'un!

There is an argument that the phase jitter of the recorded bits (that is inevitable with any form of mechanical device) will somehow effect the final result. I have also seen it mentioned that recording at higher speeds (x2, x4 etc) somehow gives a less good separation between 1s and 0s, which may give higher error rates. If you play the CD on an audio deck, I'm guessing that there is very little if any 'resampling'. The bits just go straight into the DtoA system and any errors will show up. If you import the CD data into a computer for use in an NLE, then it's going to get resampled and the phase errors will be irrelevant.
