Ok clever people can you help me Q1
I have now settled into using my HD7 and got some great results from it. We are next year going on an expedition, and these cameras have great image quality to size/weight ratio. However:
Every so often we will want to pull off the hard drive contents to liberate space. On the trip the most we can hope for is power, but carrying a laptop or JVC share station is not viable (weight). However I was wondering if: 1. I can USB straight into a small portable drive 2. Swap the JVC hard drive 3. Record to SD...as far as i can determine HD7 will record to 8Gb cards that are class 6 SDHC...any idea the what 8Gb equates to at 1440cbr 4. Any other ideas? Any experience suggestions? Q2 to follow |
I can tell you that 1 hour of standard 1080i HDV footage = 8.6GB, if that's of any help...

I think i have found the ideal solution for expedition use Its an OTG (on the go drive) http://www.card-media.co.uk/mmp25+divx+player.htm It uses 2.5" ATA drives and these can be swapped in the filed it can also be posered off 4 x AA batteries So this means we can off load the HD7 hard drive without need for a PC or come to that exterenal power. Carrying a couple of sapre laptop drives means we can carry 600Gb of storage in a the space = the camera Have ordered on with 160Gb drive (120GBpounds) will keep you posted on experience S |

To avoid any doubt, a USB disk like the Dvico U-2000C (the C version, not the Lite one) can be formated in NTFS and so, can manage files larger than 4GB. But, in everycase, I advice you to make a test before to buy. Last remark: on the actual market, there's no USB disk (except maybe 1 or 2 Professional models at many $$$$$) that can work on battery; you need an external power adaptor and an available 110V (or 230V) plug! It's possible to adapt to the USB disk an external battery block (4x or 8xAA, rechargeable or not), but pay attention to the power consumption of the USB disk: the AA batteries will last quickly --I mean, before to unload all the HD7 HDD--...

The 1440 VBR mode is around 8.6GB/hour. The 1440 CBR mode is, like HDV, around 13GB/hour; quite the same for the 1920 VBR mode. If the fact to use only the lowest HD quality is not a problem, it can be a solution to have some SDHC cards in case your disk becomes full on the field (you keep the OTG USB disk at home or at the hotel if your are in travel, and have a set of SD cards on the field, just in case of --it's better to film the last minutes in HD low rate than to not be able to film at all--).

S[/QUOTE] Keep us informed because the description of this product is not written well. It seems designed to record via a USB cable from a USB card reader. Does the HD7 harddisk behave exactly like a card plugged into a card reader? It is likely to be very different than using the HD7's built-in archive software. This software is designed to drive a DVD burner via a JVC USB cable. It would be nice to drive a USB drive using the HD7's software since it does incremental updates. Why not try it with a standard USB harddrive. Then you would not need OTG. "The MMP25 finally has the USB On The Go OTG Support which allows to copy without the need of a computer all files from a memory card (ie Microdrive) via a USB card reader to plug direct in the MMP25. All files are copied to the dedicated folder named 'cards'." |
Thanks for the points guys. You are right Steve the description on the website is hardly inspiring however it was a tech sales guy who directed me to it and is pretty certain it will wdo the job and do it from a battery pack. Best still he said i can try it and if doent work I can send it back. Steve I tried a standard USB but it needs an operating system to know what it is/where it is.
Overall I am looking for a 'go lite go far' kit that will give me the best/near broadcast quality output for expeditions. I am looking at a beachtek box to manage sound (as per my other thread). Once all is up an working i will post my expedition kit list and mods. Thanks again. |
