File wont play -but indicates that it is.

Hi there,

Thanks for all your input.
I'll grab some screen shots of the HUD this afternoon, Tried to delve into the file info in Quicktime but only got the very basic stuff, no mention of Compressor used, Timecode or anything -are these QT Pro features ?

Compressor is apple's pro compression software that is a part of Final Cut Studio. It allows you to save presets of settings to encode files as, and allows you to do batches of files at once, so you can leave 1 or 100 files encoding and it will run until it finishes them.

Aha !

I've grabbed a couple of screen shots of my HUD.

In the situations where the synced layer doesn't run, it shows that it is 1 frame behind the layer it is syncing to. (both movie files are 125 frames, 720x 576 nd were encoded using a Blackmagic DeckLink DV codec)

When it plays fine, it shows that it is on exactly the same frame.

I'll post the images once I can get them across to this windoze box.

Does this explain anything ?

Cheers

Richard

Blackmagic DeckLink DV codec

can you explain what you mean by this- and where you saw such a description - can you double check?

If you are using a decklink codec- it will be uncompressed- and you have a totally different problem.

Hi,

I got that information by using 'Get Info' box in finder.

I can only assume that the file has been captured using a Decklink card (from DigiBeta or similar) and encoded as DV.

The problem seems to be related to the layers not syncing properly. See attached screen grabs:


Confused...

which lighting desk are you using? ( i noticed some very strange things on chemical brothers last week - using a grand ma )

which computer model is this?

Which hard disc type are you using?

how many total layers are you trying to play at the same time?

Hi,

It's a new Dual 3 GHz Xenon Intel beast with 2GB RAM, we're running OSX 10.4.9, and I can't quite remember the Quicktime version (7.1.3 ?) but it's not the latest update.

I'm running it from a Hog II using the latest software version.

There are never more than 4 layers running at any one time and the load displayed for GFX card and Processor seem pretty low.

The Hard Drive is an internal SCSI -as specified (and put-together) by Projected Image Digital.

I'm going to have a closer look at my cues when I get a chance to see where this 1 frame lag is coming from as that seems to be related to the problem.

Cheers
