This week has been major crunch time for getting the show completed and ready to switch on Thanksgiving evening. While I'm writing this entry, I'm finishing up the video rendering on another computer. Things are coming together for a successful launch; however at the beginning of this week I encountered a very rough set back. One of the hard drives that make up the RAID-0 stripe set on my video editing computer failed. So, video editing was interrupted for a full day while I had to troubleshoot that problem and finally re-stripe the good hard drives and reload data from the backup. The good news is everything is now back in good working order and I was able to finally continue with the video editing.I also discovered that the Light-O-Rama DC-MP3 Director inserts a small amount of time between each sequence it plays, so keeping the video in sync with the lights was not the easiest thing to accomplish; so much so that I had to slightly alter my approach to synchronization.
I use a NewTek VT3 Video Toaster to run the video with the lights. (Yes, I know that Light-O-Rama will handle playing a video file as its audio source.) ...I always have to make things more complex - ONE video wasn't enough. I wanted TWO separate videos to run simultaneously, both synchronized to the lights and music. A special interface was built for Light-O-Rama to "talk" to the Video Toaster. Really, it was a no-brainer... The Toaster could accept a GPI trigger to signal a transition. The interface is simply a relay. When power is supplied to the Light-O-Rama channel assigned to the Toaster, the relay trips closing the contacts for the GPI trigger. But a small amount of programming and careful setup was necessary to get an automated process to work correctly. Considering that I have the SX-8, not the SX-84 means that the only video output is PGM out. So how did I manage two separate video out content? ...there are ways! My Toaster setup includes dual monitor configuration with an NVidia MX440. I set up my second monitor as a full-screen Preview Monitor. The key is that I have a VGA to NTSC video encoder hooked up to that output. So I project Preview content in one of my windows and Program content in the other window.
Now the challenge of getting two videos to start simultaneously and place one of them on the Program Bus and the other on the Preview Bus. The trick is a little bit of programming in ToasterScript combined with a plan of execution in the switcher setup. I openned 12 DDRs and put them on the switcher inputs 1 thru 12. The content of DDR1 is for Preview. the content of DDR2 is for Program. However, the only way to auto-start a DDR with Cue-In is to transition it to Program. DDR1 is put on Preview and transitioned to Program with a simultaneous transition of DDR2 on DSK. Immediately following the transition, I place DDR1 on the Preview Bus. DDR3 is set up with Black, so at the end of the sequence, the Toaster is signalled again and it places DDR3 on both Preview and Program. I broke up the video into 4 segments to help with the synchronization; that's why I set up 12 DDRs. Through ToasterScript programming, I was able to "walk-thru" the DDRs at the appropriate occasions.
