In This forum you can discuss tips, tricks, and troubleshooting for Elation's Next Generation Compu Live software, "Compu Show".

So easy it's almost scary easy. Personally, I'd like to see a few more options.

I am doing a show that is sync'd to a projected presentation(1h,55m movie). I'm using Sony Vegas for the video editing, and for work purposes, I have a file that's the same time cut as the feature(there's changes, but nothing that affects the timeline). So, I had to install my MIDI interface(MIDISPORT2X2) and then looped OUT A to IN B. I told Sony Vegas to output MTC at 24fps down OUTA, and told Easy Show to receive Sync from IN B.

That was it. Hit Play on Compu Show's Easy Show and use the transport control in Sony Vegas to run the show. I did have to set Sony Vegas to MUTE so the off-set wouldn't drive me nuts.

Not bad for a 1 computer solution.

BUT, because of this, and other stuff going on, we'll be expanding this for LIVE. We'll have the director run video off her laptop, use my Firewire 410 to run MIDI to me via a LONG MIDI cable(or a MIDI extender over Cat5, already found a bunch), and then let Easy Show just "take orders". It follows the timecode really good. I'm very pleased. The off-set can be a bit annoying, but it's usable, only off by approximately 4 frames at most, which for what I'm doing, is definately acceptable.

Right now, I am actively creating scenes and switches in Compu Show and then importing them as I go. It's not the most efficient method, but I'm still learning. But, what I like best is I can see what I'm doing in the proper time alignment.

You don't want to know how I did this in ADJ's MyDMX. I pushed that software to the max, and now despite Compu Show's learning curve, it's paying off. It will be a slow conversion process, but I still have around 45 days. I figure if I can get anywhere from 10-15 minutes of film done a day, I'll be good. There's a few rather static scenes and a 12+ minute intermission, so I expect a few breaks here and there. I have MyDMX next to me on another machine so I can see what I need to pull over.

Still lots to learn!

Well, I wouldn't go as far to say perfectly. A one computer solution with Sony Vegas driving the show isn't a good way to go as Sony Vegas is very inefficient with how it utilizes the graphics adaptor, even when using recommended cards with CUDA engines. The blame is with Sony Vegas.

The more ideal solution is to have an external source generating the MTC, which I've done by using a laptop to run the same show using Sony Vegas. Results are MUCH better. You do need to play with the MTC offset in Easy Show, which is nothing unusual. Most pro stuff will require an offset to be entered.

What I'd like to see is the option of selecting which time code to see, because it's basically doing a SMPTE with SPP to MTC but skipping the SMPTE to SPP incoming/process portion. Both sides need to be set up to the proper time code. I've noticed Easy Show will kinda do some odd thinsg here and there when chasing/locking to time code as a result. In the show I am working on, this has so far been acceptable because I have lots of tiny scenes and most run a bit long to ensure they don't run out too soon while I'm programmin and laying items on the timeline.

It's not totally fair. I've got a lot of experience with timecode and syncing all sorts of gear together.

I am programming my show using a reference video at 720X480 at 23.976 fps AVI with a 2:3 pulldown. When I do timecode tests, an offset of 9-11 ms seems to get stuff really tight. Too bad in sync mode Easy Show does a jitter-type thing, but that's not unusual for a slave to do that sort of thing.
