February 10, 2013 at 11:48 pmIt’s no wonder people are holding tight to what works for now in fcs3. That’s what we’re doing for the most part. Waiting.
The other thing is, I don’t see most of those problems.
I get the occasional pause as fcpx makes a backup or autosaves.
I get some weird renders with Pomfort.
And yeah, I get a few latent actions.
I’ve never seen exports go out of sync randomly.
7 had sync problems too if the external audio wasn’t imported just right.
Your edl and xto7 summary had so many steps to try and trouble shoot, but I’m sure you tried them all.

I’m well aware of the pitfalls with Avid and Adobe. These are all calculated risks, no matter which way you turn. I’m just tired of risking client projects on software that is increasingly causing grief.

It’s not random. Have you ever actually done exports and aligned them by phasing or superimposing against others? The export from FCP X had a burn in with the first spot starting at 1:00:00:00. The actual TC on that file is 1:00:00:01 at that point. Audio, however lines up at 1:00:00:00.
The exact workflow was to export a master file from X and an FCPXML. The FCPXML was converted/imported into FCP 7 and media relinked. Everything was accurate, except that the master file had TC that was offset by 1 frame. Sync audio was offset by 1 frame when you compared sync audio to the source camera file. This points to a 1 frame video delay internal to FCP X for whatever reason. Individual clips were not slipped. The entire timeline picture was shifted by 1 frame in relationship to the TC and audio on the exported file itself.
I doubt that sort of thing has really been thoroughly tested by too many people. Apple? Who knows?

It’s an essential part of the equation as the files get sent out of house for mixing and color correction. FCP 7 allows me to reliably reconnect, conform and verify sync. Granted, it’s not a workflow that FCP X is even remotely capable of, but that doesn’t make it unusual or unnecessary.

PS: Given your litany of bad experiences, if I’d had THOSE experiences, I would have NEVER decided to tackle some of these big jobs wit X 😉

Timecode, currently, is a huge bag of weird in fcpx.
I wouldn’t trust the tc generator working, but that’s just me. The tc reader template that was floating around broke a few versions ago never to return.
Every XML round trip I’ve done has been in sync. I have not compared a side by side analysis, no, but I’ve never had anything out of sync.
[Oliver Peters] “This points to a 1 frame video delay internal to FCP X for whatever reason.”
Does it? Or does it point to a conversion error?

There’s edl-x and x2pro. Is it out of sync there?
I don’t use Pr to wash my XML files to Color, and AAFs to ProTools, you know?

Facility doesn’t own EDL-X. Besides, I have to relink altered files, so I still have to end up in FCP 7 at the end. Facility doesn’t own X2Pro either, but it won’t do OMFs which I need for this mixer. Plus, X2Pro will not do linked files from QTs in an AAF.

Well, if I was doing this workflow, I’d look at the XML conversion and see if its accurate.

You missed the whole point. The XML conversion IS accurate. What isn’t accurate is the file generated from FCP X itself. It is NOT IN SYNC. Audio and TC match. Picture – as in the entire timeline – is delayed by 1 frame.

February 11, 2013 at 2:32 amI am trying to follow along here. There’s a ton of unknown variables that I’m fishing for. Apologies.
So everything is working and in sync, but the reference movie is off?
Is it just the tc that’s off or has fcpx added a frame at the beginning or lost a frame at the end? If you move the video by a frame, you have to make up for that loss somewhere.
What’s the tc you created in X?, an empty text generator with a filter? Or compound of the whole sequence with a tc filter?
What if you export a non-window burn, does the tc of the actual file (not the burn) match picture and sequence tc over in 7?
What I’m saying is, there’s a lot of steps here.
X can be weird, even the people who like it will say that, but if the XML is in sync…
