Hello Troikatronix team,

I'm trying to export a movie with a transparent layer, which I understand in need to use Pro Res 4444 to accomplish. I see that I can export video in the Pro Res 4444, but nothing gets exported in the video. Even just exporting a movie of a simple shape (using the shape actor) in Pro Res 4444 shows nothing in the exported video. 

Thoughts?

Hi all, 

My theatre company has a modest technology upgrade grant so we would like to purchase new projectors. We still can't afford really top-end high lumen projectors. I've always bemoaned the fact that there's such a jump between the 6500 lumen range to 10,000+, with the corresponding price difference. Recently I've started getting ads from Springtree for 8,000 lumen laser projectors at a good price and with changeable lenses. 

I think I'd like to buy two projectors right now, one for long throw and one for short throw and the Springtree price point would allow me to do that. But it also makes me nervous. Has anybody had any experience with them? https://www.springtree.net/pro...

Or, as always, any thoughts, suggestions, or links are very welcome. 

Thanks!

The information doesn't travel through HDMI: it passes via the network. So the camera has to be connected to your network.
I can connect the BM Micro Cinema Camera's USB-C port to a USB to ethernet adaptor, which allows it to join the network.
Then using the API you can control the camera.

If you can connect your 6K Pro to a network, try this:

It works great with the BMMCC4KG2.
But what I'd like would be to bypass the web interface and send commands straight from Isadora.

how much work would it be to create a BM Camera Control Actor which does the same thing as the BM Camera Control WebUI?

 Depending on the number of control points etc.. I would imagine its a day or two to build this up.

@mark_m That would be great I have a 6k pro too. They can be controlled by the ATEM software. Now, the ATEM software can be controlled via OSC through Banyan AV (aKA ATEM OSC) In order to control the atem you have do have one but all ot the camera main parameters are controlled by the atem software (even the primary colo wheels, iris shuttere speed and a lot more. All passing from the atem to the camera via HDMY cable (beware the cable ehould be compatible with Consumer Technology Association/Electronic Industries Alliance standars (no all of them are). In other words, if tiu have an atem you might be able to do that today. But for sre it would be simpler to have a python script. Although I don't know how the information would travel through HDMI. If someone comes up with  a script I can test it for sure.

All the best

Hi,

I think the problem might be the way the memory number is passed. In the user input, the memory number must be an integer (1, 2, 3, etc.). Within the TCP Send actor, the P1:C parameter converts it to the hex value 01. I tested it this way and it worked fine.
Best regards.

@jandraka, amazing! Thanks!

After some false starts, I've got it sort of working (Ok, I just need a bigger screen so I can see what I'm connecting). I had to adjust the trigger delays otherwise the projector wouldn't register the ESC/VP enable command. 

Mute On and Mute Off work great. Memory select works if I send converted hex string with the memory position included in the string. The ASCII command version isn't working though. I think it's an issue with the parameter? If I have a little more time this afternoon, I think I'll try the hex string with the P1 in place of the memory position.

Worse comes to worse, I could brute force the solution by setting up a different TCP Send for each position I might use...

Thanks again!

TD

EDIT: I re-did the TCP command to be fully a hex string with P1 in place of the variable, and it works! Yay!

If something has an API it's almost certain one can control it through Isadora using one actor or another (probably Pythoner).

@t_decker

I forgot to mention that for TCP communication via ESC/VP21 command protocol, you don't need to activate the web API on the projector.

Best

As I replied to your support ticket:

I just opened Isadora 2.6.1 on my Windows 11 machine and it appears to be working as expected. 
Do you have third party plugins/FFGL effect etc installed? You might need to Hide anything like that from Isadora (rename the folders.. I generally add '_HIDE' to the foldername) That way the externals won't be loaded the next time you open Isadora. 
You can also, try deleting your preferences file. It may be that something about your video config changed with the update, and this will reset things.
You can find the preferences at: C:\Users[YourUserName]\AppData\Roaming\TroikaTronix
