Sound and sync

[Improve]

You dont need to sync different computers together, because they playback accurately at 25fps or 30fps - unless the drives have to do too much.
Software is designed for accurate playback of movies - as long as your drives are fast enough.

Im at eurovision in istanbul + turkey + and we have 8 ( eight ) g5s outputting onto a single huge seemless video wall..
And there is only a very tiny difference between movies.
movies playback at the correct time - not using the 'sync' function.
But we may have to use it with certain movies where image continuity is critical.
You really would notice it in this type of environment.

Audio - in the professional environments that this software is used in - is a huge can of worms - that i have addressed before.
It is something i have been doing for years in my show control stuff, i do not feel comfortable having high end support one more feature right now.

If you want to sync to a professional audio source such as yamaha or other hard disc playback units then you use the midi time code sync function that is in catalyst.
I have used this on shows.

Thanks for you're reply,

However, I have done a show recently with two servers and two DL1's. There where two moving screens, so each screen a DL1. Finally the screens roll together to a wide screen. The movie for this consists of two movies, a left movie and a right movie. They have to be played within the frame accurate, most of the time this was the case, but offcourse during the performance there was a frame or a few frames difference wich offcourse can be seen. The only way then to sync exactly is by using the sync option, right??

FYI, both movies were started simultaniously by a hog, the hog was started through showcontrol wich also started a harddisk DOREMI for the sound.

How long were your clips?

What computer and disc system were you using?

What computer and disc system were you using?

I had two G5's. One standard dual 2G with ATI 9800 and standard HD, and the second G5 also with dual 2G and ATI 9800 but with a raptor drive.

Clips were 2 min 50 sec long, and compressed with Motion JPEGA

so you had different disc setups in each machine?

and what compression quality with mjpeg?

and how many layers at the same time?
