My setup is the following:
- BlackMagic Television Studio
- MacBook Pro for controlling the BlackMagic TVS
- A video camera connected via SDI (stands in front of a blue screen)
- MacBook Pro with QLab 2.0 for back- / foreground connected to the TVS
QLab's rendering:
- 1x Video background @ 720p (QuickTime - JPEG codec)
- 3x Video footage @ 720p with alpha (QuickTime - HAP codec)
These four video layers needs to play at one time all together. But unfortunately the images stutters already when playing the video background alone. Image what happens when playing these four layers together. ;)
The MacBook is pretty new and filled with 16 GB of RAM, so I can't imagine thats is the biggest bottleneck. Is there a possibility to load the video's in the RAM before playing it? Or are there other things I can do to make the playback smooth? Maybe other cue-able programs?
Thanks in advantage!
