File wont play -but indicates that it is.

[samsc]

It doesnt seem to always happen, as I did batches of encoding where the files were all made using the sme program, with the same settings, etc, and it only happened on one file in the batch.

that file probably had the math error between the movie information headers i indicated above.
they are doing a frame conversion with non-accurate math.

one of my users reported using several different output codecs and it not working with any.
so it could be this...

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 ?

It's quite possible the files have been buggered about in Post before making it my way, their Aspect ratios have been squashed such that I've a 12:3 image in a 4:3 format so they could have been subjected to almost anything.

Cheers

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 ?

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?
