FS7: Another 4K HDMI / SDI Question...

[jasonbrooks]

Hey folks,

I've been looking into the most affordable, yet relatively solid/reliable method to get wireless monitoring for a feature shoot.

Thus far, kit acquired includes:

PDMovie Wireless FF kit.
Shogun Flame as a daylight-viewable 1080p monitor for focus-puller.
IDX CW-1 as HDMI transmitter.

So far, so good. I have a way to monitor (very) low-latency FHD images from the FS7 ... IF ... there's a 1080p signal coming out of the HDMI output. And that's the big IF.

I'm interested to know how much it would cost to use the same setup, with the addition of a SDI-to-HDMI scaler on the FS7 end of things. This would (I think) allow me to shoot 4K internally on the camera, whilst still sending a (SDI/HDMI converted) FHD signal back to the monitor for the focus puller.

I'm looking at one of these: https://cvp.com/product/atomos_atomcscsh1_sdi-to-hdmi

If anyone has any experience with this device, or knows of another better or cheaper way to do the same thing, please do shout!

I'm aware that the 'proper' way to do this would be with a wireless SDI transmitter, but they're over £1K more expensive than the IDX device (and I already have it ;-).

Cheers,

jason

... at the risk of talking to myself, I just found this:

And am wondering WTF is the difference between the two (accounting for the ~£400 price difference!). Anyone have experience with these little b&$tards? :-S

I've been very happy renting the Teradek products like the Bolt, but I'm guessing that's outside the scope of your budget!

I'd recommend the new Swit CW-150 - faster, more reliable and with better powering options than the IDX. I did a side by side with a teradek bolt and the Swit was faster.

The IDX design isn't very robust, I had overheating issues with my old one and it finally rolled over and died on a shoot in India.

There's also an SDI version.

Doesn't FS7 send 1080 signal over SDI regardless whether you shoot 4K or 1080? I don't have the camera in front of me and I do remember some restrictions when shooting 4K ( I believe it's not possible to send 1080 through both SDI and HDMI while shooting 4k / UHD) but since it is possible to send 1080 via both SDI's while shooting 4K, why not simply use a simple SDI to HDMI converter which does not need to scale anything? No name ones sell for $20 and Blackmagic is $39. https://www.blackmagicdesign.com/products/microconverters

Just some waffle..

I like to operate on my hdmi small HD.

I have the excellent animon mini transmitter.

Last week I tried taking the SDi to a red byte decimator to get a second hdmi feed - no luck but have not interogated the menu (any ideas please??)

Anyway took hdmi out of the smallhd to the animon.

Result.. Omboard and remote monitoring at high quality
