What's the bug? That Isadora doesn't like H265?
Yes, or that it doesn't like something else specifically about these particular h265.mp4 video files (though h265 is most likely the source of the issue in my opinion). Either way, I now have media and clear repro steps to cause the problem, which made it easy for me to log this issue.

We're aware of the issue, and it's already been fixed for the next release, which should be coming very soon. :)
(For the record, this annoyed Ryan as much as it annoyed you. I never would have found it because I never drag Control IDs; I always assign them numerically via the Property Inspector.)

@jjhp3 Hi John! With the very basic patch shown in the screen shot below, I didn't encounter the issue you describe - the info panel and all properties, including Ctl ID Link are accessible. However, as an alternative could you just click on the actor property, such as intensity, to reveal its info pane and literally type the control ID number you wish to associate with your Slider control residing in the Control Panel?
Hope you find a fix.
Best wishes,
Simon

@woland: Thx for looking into - with the converted footage working with Isadora is fine again..

Howdy— New behavior which I find irritating: when I drag a control ID to its intended input control, the small info pane immediately opens which, in most cases, obscures the placement of the ID I'm dragging. If that makes sense... Thus I can't be sure if I added the control ID to the correct input or not. I use control IDs a lot! Doesn't happen with 3.2.6 on my older intel machine. New behavior came with Isadora 4.0.7?? The "small info pane" refers to what used to appear when clicking on an input such as projector intensity which allows one to set min max numbers etc. Thanks for a great program! — John

Looking at the media info for your two imported video files, they list the codec as "hvc1" which indicates that these are h265.mp4 video files, which are not officially supported and is probably the source of the strange behavior. If you convert your media to h264.mp4 you should have an easier time.
Thanks for the media and the very simple file though, it makes it easy for me to repro the problem and log this as a bug.

I'll take a look later today

I realize this doesn't come in time for your show, but the third Scene of this file might be helpful in understanding how to preserve higher resolutions when mixing content together:

@woland: Like noted previously the error occurs only with delivered footage. Also checked for virus possibly included to the 2 mp4 files, luckily negative...

Thx for having a look deeper ]:+>
