Battery Powered Monitor for bag mixer

Recommended Posts

Im seeking a 7-9in monitor that can accept two camera feeds and be powered via Np1 box on the back. It needs to be easily mounted to a magic arm to clip on my rock n roller card and quickly removable as well. Any input would be greatly appreciated.

What type of input SD,HD? Input type BNC, HDMI, SDI- all? Are you locked in to the NP-1, it would seem that the box would be larger than the monitor itself.

From some of the ones I've seen, I have only come across mulitple video feeds, but from different input types. Check out this Marshall monitor. Also, you're probably aware of the Sound Devices PIX 220-240, which I don't think have come out yet. I haven't found any details as to whether the PIX 220 and 240 will have multiple video inputs.

Ideally HD would like BNC/ SDI as I do many RED shoots with no down conversions. I already have 10 Np1 batteries and would prefer to power it that way but open to buying other battereies. I have been browsing many options but the prices are so high I am just tired of having to mix blindly with operators and zoom lenses

There are definitely professional field monitors that have an AB battery mount plate on back, built-in tripod thread and will accept HD-SDI (as well as other inputs). They are always wrapped in some sort of Portabrace-type covering so I don't know what make/model they are though, and no idea what they cost. That would be your all-in-one solution.

A lot of people have been using down converter boxes with a small 7-9" monitor. Basically you buy something like the Decimater2 for about $500 and hook it to a cheap monitor, or you buy a monitor that has that kind of technology included. In the end, it is probably a bit cheaper to have the separate units. The people buying 7" LCD monitors with HD-SDI are professional users, and end up paying for the relatively small run of those products.

You could get a NP1 box with a power out that will feed your monitor (most are 12volt) and velcro it to the back.

be aware of Sony LCD as some of them have pretty loud fans.

a monitor with two SDI inputs won't be cheap. out of my experience I do not know any. HDSDI makes monitors expensive.

I have a quite expensive tvlogic http://www.tvlogicus...duct.php?idx=29 with several inputs but only one SDI.

the smallHD is very rugged build and really sharp (colors a bit of) but has also only one HDSDI http://www.smallhd.c...ducts/DP6.html. but toggeling sources takes too long for you as its with that little wheel.

Manhatten 8.4" is the only dual HD-SDI i found. havent seen it though. Make sure not to buy the 250cd version - 350-400cd is what you want on exteriors. http://www.bhphotovi..._Pro_Field.html Power consumption is quite high and 1900$

Thanks for all the help all of these are way out of the $500-600 price range I wanted to stay in I guess I will just continue to mix blindly or attempt to set up near video village. I just can't justify the expense when my weekly rental rate is so low since I like in the Tier 1 world when I do mix a feature. Most of these feature don't have a proper video asst so I have no way of getting a down converted and many times I can't even get help getting a video feed its very frustrating.

I totally understand that price concern. But you won't find a monitor in that price range with even one HDSDI.

Even cable issus won't make friends anyway.

Wireless HDSDI to Ipad - maybe you can find cameramen to like it have no BNC to their camera :-)

Downside can be the latency of about 1/4 second

My guess is now you've put the idea out there, you'll start getting gigs that have downconverters. Happened for me once I started asking the downconverter question during the initial phone conversation with the UPM :)

I know some guys who add an A/B switch in line, with two inputs for A and B cameras. Worse comes to worse, I've dealt with one monitor OK so long as I see the widest of the two, which is not always easy to accomplish with zooms on set.

My guess is the cheapest, smallest solution is a dual downconverter --> A/B video switch --> single monitor or some variation on that theme would do the trick you need to accomplish.

Good luck!

Many "old" monitors designed for car use are very cheap on ebay, and you can easily make it run on an NP1 by repurposing the black and red wires on the wiring harness. A passive A/B switcher is also very cheap. Production should include downconverters at any level if you tell them it's critical for you to see what cameras are doing (2 cameras on zooms) to mix their project properly.

My response got crazy reformatted after editing it, so a shorter version....

1) roll your own solution:

down converter ($500 Red Byte Decimator2 or Blackmagic mini) + 7" LCD ($40-$300 for a basic LCD TV up to a professional monitor) + $50 battery box adapter solution = $600+ depending on how you build it.

2) all-in-one starting a bit over $1000, like the Marshall V-LCD70XP-3GSDI. They make models with all kinds of battery mounts, so one of those NP1 boxes with adapter mounts would probably work.

The Marshall is a far better quality monitor, has the ability to flip the image (good if you do film), 1/4" 20 tapped holes on all sides for mounting options, XLR4 DC port in addition to the battery mount, bla bla bla.

I would still request a SD feed on jobs and explain that they should provide a feed you can use.... especially if they won't pay for you buying a monitor that can digest their signal.

Side Note: I have gotten some really dirt cheap mini ball heads on ebay for mounting my monitors. Under $10 shipped. I would not mount an expensive camera on them, but that little adjustment is perfect for a lightweight LCD monitor.

BTW, you said RED shoots, so i *assumed* you needed to handle an HD-SDI signal. The RED only has HD-SDI and HDMI outputs. If you can use a HDMI signal, then a cheap computer monitor would work. Basically the chip that can decode a coax cable into the same data the many pins of a HDMI keep separated are what makes these HD-SDI monitors cost an extra $500.

Hi,

Have a look at Data Video monitors. They are a little cheaper than the Marshall ones, and have bnc, sdi, and hdsdi inputs. I have taken one through all extreme conditions, and it hasn't missed a beat. They do have a V-Lock system, but you could always can an IDX NP1 to V-Lock adapter for around $300.

I had a bad experience with Datavideo monitor in terms of picture quality. It looked so aweful blue to me - but maybe that unit was broken. Not bright either.

I stumbled upon this 422 Euro Monitor with HD-SDI: http://swit-battery.nl/shop/product_info.php?cPath=21_23&products_id=167

Website looks not that truthful. But the batteries are well known here in germany.

Cheapest HDSDI Monitor I ever saw. 4.8" maybe better in a mixer bag than 7"-8,4" -smaller and lightweight.

bandpro price 600 Euro + Tax.

This marshall actually looks pretty good after researching the DIY solutions this seems good thank you
