Hello folks,
I ran into issues last weekend when using PNG files with an alpha. I was using 1920 x 1080 still png's. output set to 3840 x 1080. The stills were being resized to fit in the booth panel by using a layer.
Once I would mix in my other 4 layers and the Stills layer had a PNG loaded, the entire output would drop framerate big time when adding any fx like a strobe.
I re-encoded them as HAP files and the problem went away. However, later in the evening the client handed me a png file mid set, and I had to tell him I can't use PNG files or the system will hang.
I'm assuming the dropped frames was from vdmx trying to re-calculate the alpha channel on that layer.
