Dan,

Thanks for creating such a ground breaking tool. The complete Paralinx review can also be seen in full HD on the ACS Vimeo site. There are some handy hints for optimising performance in the review. I am looking forward to seeing more developments from Paralinx.

Great video, thanks !
I'd like to hear more about that dropped frame issue when removing the HDMI cable while recording on the Epic. (they mention it at 11:00 on the video https://vimeo.com/60520896 )
I think I've seen that a couple of times. Is there a workaround ? What is Red's word on that issue ? Can it also happen when the arrow loses the signal ?
 
This was an issue reported to me by a very experienced DOP shooting with multiple Epics on a Network TV Drama. Unfortunately this issue was discussed after our test days so I did not attempt to recreate the error. This would seem to be an Epic specific issue and may even be specific to their cameras and build. There is definitely no frame drop when the Arrow loses signal I imagine its something about the physical disconnection that causes the issue. If this was a repeatable problem I personnaly would not be greatly concerned as pulling out the HDMI cable during a record is unusual and the position of the Epic HDMI plug is fairly good. I do not have an Arrow with me why doesn't somebody test and post the results?

A bigger issue is the new +1 Module taking the HDMI port with no pass through. Do not know how you will be able to use the Arrow and +1 Module together without an SDI convertor?

I had the issue while operating normally (no power loss to Paralinx and no dropped signal). We had several dropped frames but no warning from the Epic. Had the problem with two different camera bodies. I've also had weird glitches plugging in HDMI from Epic to a television.
 
The issue reported stems from a physical disconnection of the cable ( detectable or undetectable) to the eye when using the hdmi port on Epic or Scarlet.

Issue repeatable with any hdmi device by plugging and unplugging the hdmi cable to the camera.

Issue has been reported to Red who noted that it should be solved in a revised firmware build.

best,

Dan

Just thought I'd share my director's monitor setup and little gadgets I found to be useful for this to work. Cheers!

Thanks Dan!

I've actually used them in conjunction with three GoPro HD Hero Blacks this week. We were doing a live show for the GALLO WINES event in Las Vegas. I was running the GoPros with the Paralinx to run a live feed into the back so they could intercut with the cameras covering.

It didn't go too well. Not because of the units, but because of all of the RF interference. Had to lower quality to WVGA on the GoPros to keep a strong signal. It's just not exactly what they were built for and we really pushed them.
 
Here's a great tip to avoid RF interference when running more than two:

Boot first transmitter
boot first rereceiver

run a stopwatch 60 seconds exactly

boot second transmitter
boot second receiver

run stopwatch 60 seconds

repeat for 3,4,5, up to 6

Reason is : FCC regulation of expanded Dfs frequency blocks.

Hello Dan,

Any hint on how the HDMI signal from the Epic could be split to feed the +1 module and the Arrow?
I would try not to use any HDSDI cross conversion to HDMI box to get the camera weight low

That +1 HDMI connection is tight. There is no way to split that off the HDMI. Your better bet is to use the Atomos SDI to HDMI convertor.
 
@patrick - I can't say anything just yet - but I can say that all our future accessories and products will keep with the Paralinx Mantra of Simple, Affordable, Lightweight Wireless HD.

Hope that is a hint enough for you without saying too much.

Best,

Dan
 
Hey Dan, just wanna say thanks publicly for you and your company's impeccable customer service in helping us out in such a small window. Tim took care of me. We just went ahead and bought instead of renting, just on the strength of our experience dealing with you guys. Should arrive any minute. Can't wait.
 
Dans costumer service is one of the best in our business. I had a false alarm, where it was actualy a defective monitor, but Dan replied to my email within minutes, offering a solution right on the spot.
Because of that, I sold a Bolt system that I had and I'm now solely a Paralinx costumer. Very pleased!
