Re: Gy-hd251

Re the epoxy , what I was thinking of , rather than bonding to the casing of the camcorder , was to apply gaffer tape around the socket as a masking layer ( this was just to make it easier to remove , I wasn't aware of corrosion issue ) , then to use an enclosure around the socket to contain the resin . I'm looking at cutting the top off a Lego brick and using the rectangular sides . The main thing is to stop the sides of the socket from spreading . Once it has set , I can dress the epoxy back with my Dremel and a cutting disc .If I need to open the camcorder I can equally cut away with the disc .

With the thin FireWire cable the need might not arise ; I won't do anything before getting and testing it . I'm also looking for right angle FireWire connectors I can use to make my own cables , haven't found any yet , but I only started looking tonight .

The Firestore seems to be working well enough , but the final option might be to look at using something like an Atomos Samurai connected to the HD-SDI output , which would also give 1080i functionality .

It's still early days as I've had the camcorder less than a week , and only been using it for one day . I won't do anything irreversible without weighing all the consequences .

Re mounting the Firestore , the cradle I have is mounted onto the PAG V-mount to PAGLOK adaptor plate and not to the camcorder itself ; this is the same plate I've been using to attach my PAG L95 batteries to my DSR500 and it has been fine ( it was ex BBC kit ) .

Re: Gy-hd251

Hi Derek...
I just picked up 2 JVC GY-HD200 cameras recently from Ebay with low hours and in mint condition... they do produce fantastic images... I am having fun using them... I did pick up a Firestore HD unit for the JVC cameras also but have not played with it yet as I am recording to tape...

I can tell you for tape playback you can use the JVC BR-HD50 deck obviously... BUT I was surprised to learn that my Sony HVR-M35U deck will also playback the JVC tapes... I get a nice image on the monitor attached AND it will also send the JVC HDV stream down the HD-SDI output, and I also assume down the firewire (but have not tested that as of yet).... I think this may be the only Sony deck in the HVR line that will play these JVC tapes although I could be wrong on this. I know my HVR-1500A and HVR-25U will not do it.

You might want to look around for a deal on an HVR-M35U deck...

Re: Gy-hd251

Hi Dave , glad to hear there are others still enjoying these fantastic cameras .

My Fujinon TH16x5.5 lens arrived the other day , in mint condition , apart from missing the lens hood , but I've been in touch with Fuji UK to try to source one .

This Fuji lens really is tiny compared to my Canon lens ( just over half the length ) and much lighter - so much so that it really shifts the balance to the back of the camera when the battery and Firestore are hanging there . I've still to fabricate a bracket to hang a wireless mic receiver on the other side .

Purely by chance , though , the Fuji lens shares the same 82mm filter thread at the front with my Canon lens . It is close enough in external diameter ( 85mm ) that my Canon lens hood can slip on , but since the front barrel of the Fuji lens is made of plastic rather than metal , when the locking screw of the Canon lens hood is tightened , just enough to secure the hood , it deforms the Fuji lens barrel enough to interfere with the internal focus .

I've got an 82mm adaptor for my Lee filter holder , and a matte box which will attach to the holder , both on order , and good to know I can use them with either lens . I still need to play with the two lenses a bit more as I can't yet determine any difference in performance . What I have found ( and expected ) is that my Canon zoom demand controller will only zoom the Fuji in one direction ( had this with previous Fuji lenses ) , but the Fuji zoom demand I also have , which has worked with previous Fuji lenses won't zoom this one in either direction ! I need to get my meter out .

That's interesting re the HVR M35U . I went onto the Sony website and downloaded the user manual .

While it will play the JVC tapes and out put via HD-SDI , it won't output them via Firewire ( see paste of page below ) . My existing HVR M15 will play them via analogue , so I'll need to look at different capture options for either of those machines , although I've also got an alert set on eBay for any JVC BRHD50s that come on the market .

From the Sony HVR M35 manual -


1) The format of the picture output from the HD/SD SDI OUT jack can be set in [SDI/CMPNT] of [VIDEO OUT] in the [IN/OUT REC] menu (page 73).
2) Outputs signals down converted from HDV format. The setting for down conversion can be changed in [DOWN CONVERT] of [i.LINK SET] in the [IN/
OUT REC] menu (page 74).
3) Through the down conversion, HDV 4-channel audio is converted to 2-channel audio. The setting for down conversion can be changed in [DOWN CONV
AU] of [i.LINK SET] in the [IN/OUT REC] menu (page 74).
4) 24p signals are converted to 60i signals by 2-3 pull-down, and then output.
Notes
HDV 720/30p/25p/24p signals can be played back but cannot be input/output via the HDV/DV jack on the unit. HDV 720/60p, HDV720/50p and SD 480p/576p signals cannot be input/output, recorded, or played back on the
unit.

Re: Gy-hd251

Having played a bit with both lenses , there seems little to choose between them other than focal length , at least on initial impressions . The Canon lens , not surprisingly as it was originally much more expensive , is more solidly constructed and made of metal where the Fuji is deformable plastic , but the zoom and focus movements of each are equally tactile .

The Canon , with its 2x doubler , offers more reach , while the Fuji is 1mm shorter at the wide end ( hardly worth bothering about ) . The Fuji is much lighter , which would be a bonus for extended handheld shoots , but it leaves the camera heavy at the back , even without the Firestore and the wireless receiver mounted , and with the shoulder pad all the way back . With the Canon lens mounted , the camera balances nicely on the shoulder with the Firestore and a PAG L95 battery on the back , the wireless receiver makes no noticeable difference .

While I already had a bracket for mounting the Firestore to the camera , it was attached to the V-Mount to PagLok adaptor plate I have for my batteries , I fabricated a bracket to mount my Sennheisser EK3041 wireless receiver onto the two threaded mounting points on the other side of the IDX plate on the camera ; this now stands the receiver off just enough to allow 90deg BNC connectors to be plugged in if required and keeps the receiver just clear of the tape compartment door when open ; it is neat and secure , and doesn't get in the way when the receiver isn't in use , I also made up an XLR cable with 90deg connectors on both ends which allows connection without the cable getting in the way of anything .

On the subject of cables , my Apple thin Firewire cables came in , these really are the best , being very nicely constructed and lightweight so that no strain is put on the camera Firewire socket ; I have it routed round the PagLok adaptor plate and secured with a length of double sided Velcro in such a way that it can't snag on anything and yank at that fragile camera connector .

I haven't handheld the camera with my new matte box which arrived today , but I expect it might be a little front heavy , but that might be compensated for my moving the shoulder mount forward . The matte box will be more for tripod mounted shots anyway .

Fuji came back to me yesterday re the hood missing from the lens I bought , it is still available at a cost of approx 43 , so I ordered one .

Re: Gy-hd251

Further to the matter of capturing from tape , and not wishing to keep using the FireWire port on my camera , I just bought a Matrox MXO2 capture system , which comes with the PCIe card to go in my MacPro , an express card 34 adaptor to use with my MacBook Pro and a Thunderbolt adaptor , which I don't currently need . This will allow me to play in 720p footage either from the HD-SDI output from my camera , or to use the analogue component outputs from my HVR M15e deck ( which does output HDV 720p ) , until such time as I manage to obtain either an HDV M35 or a JVC deck ( if I end up getting a JVC deck I'd need to also keep my Sony deck to play tapes from my Sony camcorder which are HDV 1080i .

The Matrox unit will also allow me to capture from analogue tape formats , something I very occasionally still get asked for . While once an expensive bit of kit , these things are now very cheap to buy and will generally come in handy .

It should arrive later today .

Incidentally , I sold my DSR 500WSP and my DSR45AP the other day , which goes some way towards what I've been spending on new toys lately , and whilst up in the attic I identified a pile of other stuff I'm unlikely to ever use again , so time for a further clearance .

Re: Gy-hd251

In case this is relevant to anyone else , the Matrox MX02 arrived at the end of last week ; I got it connected up at the weekend and took the analogue component outputs from my HVR M15AE into the component inputs on it .

There was a bit of faffing around with drivers ( the earlier Matrox V2.6 drivers support FCP 7 , which I still use , but are only supported to OSX Mountain Lion ) . When installing this , FCP 7 shows all the Matrox capture presets within the AV settings menu , but they don't seem to work .


The later V4.6 were designed for OSX Yosemite , but by that time only support FCP X . FCP X does not support direct capture , but the Matrox software comes with a Vetura capture utility . After my getting a bit confused with source video formats versus capture video formats ( you can present a source video in one format to the Matrox , and capture it in another , different , format with real time conversion ) .

After getting the settings sorted out , I was able to capture material from the HD-SDI output of my GY-HD251 into the Matrox .

I found that , amongst a wide range of supported formats , the Matrox supports 720p 50 , but not 720p 25 , so I can't play the tapes in my Sony deck which won't play 720p 50 .... back to looking for a JVC deck I think .
