hi

here is my problem :

I filmed a short in 35mm at 24 fps with a sync sound at 24 fps
it's for a final print.

The editing was done on FCP with the flex list.

this editing method was refused by the lab who asked an editing with the tc time code wich is at 25fps. (what the editor did)
and now we are out of sync for the sound !!

is it normal that a lab refuses an edl based on a flex list?
don't we do any more films at 24 fps or i'm i missing something.

It's a verry well known lab in belgium that i'm going to call tomorow .
i'm verry interested in your point of view
thanks

You don't say what speed the telecine transfer was done at. There are almost invariably complications in this process, and the only way you can be sure of avoiding them is to talk through the process with your telecine house, your editor, your sound editor, and your neg cutter and your lab. (who may all be one or two people of course).

They all need to have the correct settings or else the cutting or the sync will almost certainly go wrong.

For example if you telecined at 24 to PAL, then you will have a different number of video frames to film frames. Neg matcher can handle this, but it's a nightmare. If you telecined at 25, then you will have the correct number of frames, but 24 frame timecode won't relate directly to anything much.

I'm wondering what would happen if you shot PAL and telecined to NTSC, would you just get a longer run time?
