Universal Audio audio driver

 There was an issue in the past with a Nahimic audio driver, that wouldn't let Isadora open. Do you have anything by that name?

Could be. Have you tried removing it?

Just out of curiosity, could you download Isadora 4.1.3 and see if it launches? (Isadora 4 and Isadora 2 can be installed on the same computer without interfering with each other, and you can try launching Isadora 4 in demo mode, without a license, just to see if you have the same problem.)

I’m revisiting this post because I still haven’t found a solution, and I’ve done everything DusX told me to do… Isadora (2.6.10) won’t launch. I wonder if there might be an incompatibility with the Universal Audio audio driver? This has been happening ever since I installed it for a sound card.
Thank you for your reply

Thanks @Skulpture and @Woland

After exporting several different file and codec combos, I realized that it was actually (maybe) a lag in my hdmi extender, which is old and not HDBaseT. I don't do a lot of this kind of content, so the lag was just much more evident...close ups of actors faces so the audio and video were just out of sync because of the lag.

Or at least that's my current theory. I ordered some new HDBaseT extenders and I'm hoping that will solve the problem. But I am using QT/Hap Alpha for the record.

Thanks, as always!

 Hmmm I am not so sure. HDBaseT is marketed as zero latency. Unless the hardware is faulty or there are other factors we aren't aware of. Let us know how you get on.

 Can you run a test without the adapters, just a direct connection to a Display?

point by point process

 Yes, only the selected points will move, and they all move the same amount. I 'stretch' type move would be a great feature request though. I will add this.

is there any way to grab and move one of the corners and all the other grid lines will warp proportionally

 These little guys control the different types of mirroring (horizontal, vertical, and diagonal):

@jrhooker

Try exporting it as each of the following:

1. hap.mov
2. h264.mp4
3. apr.mov

@jrhooker what video file type and codec?
