Title: Hollyland Mars X help
Post by: garry23 on February 01, 2021, 06:47:05 PM
I've just got myself a Hollyland Mars X HDMI wireless transmitter to use with my photography, ie not videography, ie as an experiment, having convinced myself it will work.

https://www.hollyland-tech.com/products/detail-39.html

The use case is mainly with my 5D3 and composing the scene and controlling the camera, Canon and ML side, when the camera is low, on the ground or LV is not easily viewable. All the time using my iPad or iPhone as a wireless monitor, ie rather than the  camera's LV.

After a few hours playing with it, it does indeed seem to work on the 5D3, and I'll write up and report on my experiences as soon as I can.

The device connects at 1080p24, ie as shown on the Mars X unit.

My problem is I can't seem to get the EOS M to be recognised by the Mars X unit.

I've tried forcing HDMI in ML, ie on and off, and I've set the EOS M to 24 FPS.

Remember I'm in photo mode in this use case.

Can any of the video gurus suggest what I might be doing wrong, ie so that the Mars X works on the 5D3 but not the EOS M. 

Maybe, sadly, it simply doesn't work with the EOS M :-(

Cheers

Garry

Yes, what Danne said/wrote: Are you able to connect EOS M to another HDMI device (monitor, TV)?

Sorry, been doing a bit of testing.

Tried 5D3 with two different cables to connect Cam to the Max X unit. 

Max X connects at 1080p24.

Tried cables on my EOS M to a monitor, and the HDMI out of the cam comes through ok, with or without ML being loaded, ie SET pressed at start up.

Bhphotovideo site says this

Huh? The 5D3 does 1080p30 via HDMI and not 1080i60?

The Mars X says it is connecting at 1080p24 on the 5D3 and all is OK :-)

It's that little EOSM bugger that's annoying me ;-(

Can someone in the know confirm that the HDMI out on the EOS M is p rather than i

I've looked in the manual and all it says is 1080.

Thanks in anticipation.

Ok, I've convinced myself that, like some other Canon cams, the EOSM's HDMI output is interlaced and not progressive like, say, the 5D3.

Damn!
