Edge Blending & Frame Sync
Posted: Tue Jan 29, 2019 00:40
Hello Everyone,
I will be rear-projecting onto a curved screen using 2 projectors, edge-blended on center to create one, panoramic image, approximately 3840x1080. Some of the content will be the top or bottom half of 4K video or still images fitted into the elongated aspect ratio.
For the videos, I am concerned about frame sync between the left and right projectors. Would it be best to use something like a DualHead2Go or Datapath Fx4? Or would it be better run 2 separate streams directly from my MacBook Pro's Thunderbolt 3 ports, each to a playback device like something from the Blackmagic Ultrastudio line? To give you an idea of its video output capabilities, the MacBook I am running has four Thunderbolt 3 ports, each capable of driving a 4K monitor (driving up to four simultaneously).
Any advice would be greatly appreciated. Thanks!
