Video Issue Qlab3 - low quality

[Pedro Freitas]

Good afternoon.

My name is Pedro Freitas I'm a portuguese Audio Engineer and I'm currently doing a Theater Show in Lisbon, Portugal - in a movie Theater. The company I'm working for bought the new Qlab with a Pro Video License.

Our show has video and audio. It takes place in a movie theater and we are using their sound system (5.1) and their screen and projector (screen SCOPE : 2048 X 858).

I have a bunch of video cues RES: 2048 X 858 mp4 format and I'm using an early 2015 Macbook Pro 13" Retina display running the latest Qlab through HDMI output into a NEC2000 projector.

My main problem is that I can't get the quality I was hoping for on the screen. On the mac (running the videos on quicktime) the videos seem flawless and with crystal clear definition, when I view it on my surface 1 in Qlab ( Macbook screen) the quality seems to go down , the image looks out of focus and pixelated, and when i view it on my surface 2 (the movie theater screen) it looks bad also.

What am I doing wrong?

Can't Qlab handle videos with this resolution 20148 X 858 (cinema scope)?

I know my mac can handle this resolution, so does my Hdmi cable and so does the projector.

Are there any steps in the configuration of my surfaces I'm doing wrong?

Please help.

Best Regards,

Pedro Freitas

What size are your surfaces?

I have just run the test video EBU Park Joy on a spit screen with Qlab and Quicktime Player ( by setting the cue to custom geometry and setting surface 1 to  partial screen 1 of a  2x1)

Apart from the fact they are rendering in slightly different colour spaces they look identical. The attached screenshot is from a 1080p but I am downloading a massive  2160p 50 fps as the ultimate test and will screenshot that when it is finished downloading

If your Qlab output looks like this, you have probably set your surface to a small size. This one is 400x225

And here's a 2160p frame rendered on a 2560x1440 monitor (and surface)  Qlab on the Left, QuickTime Player on the right.

Check your codec! I noticed this too on some content: in quicktime everything looks great, but in QLab it's like SD resolution. Re-encoding in ProRes resolved the issues for me every time!
