FCPX export BUG!

I've finished a test about fcpx's export bug.
When export master file @Prores422, you will got 1 frame longer than your sequence!
The position of the frame is random!

the efficiency solution I think for now is:

install 10.0.9 to the same mac pro, find the added frame in the 10.1.1, and delete it in 10.0.9
then export!
10.0.9 has not that BUG.
the mac pro's export time is good if you've rendered all the timeline, 0.25 times timeline duration on mac pro2013 (6cores D500)

I've download a adjustment layer broadcast safe to make every frame of your timeline to be rendered.

You're going to have to give some more information like the frame rates of your media and the frame rate of your project. Also what version you're using.

I exported a 45:09:05 project at 23.976 and that's exactly what I got. Nothing needed to be rendered, except for the conversion to ProRes to make the master file.

I've tested 24p 25i 120mbps 185mpbs
10.9.2 10.9.3
fcpx10.1.1
no less than 4mins 30s will cause that bug

Conversion to prores is transcode, that will not cause the bug.

From the reports I have received about it, this mainly happens when exporting to a PAL interlaced format. That's why many people do not have this problem. The codec does not seem to matter, although XDCAM gets mentioned a lot of times. The current workaround is to drop any adjustment layer above the timeline before exporting. This does not affect the quality nor the export time. We export long PAL timelines on a daily basis, but never to interlaced formats, and I have not seen this issue before. But it's good to keep sending feedback to Apple about this.

What do the data rate numbers means? Please give exact specifications. Are you exporting to H.264? Do you mean 24fps or 23.976?

Do you're saying exporting a master file to ProRes won't produce this result? No idea what you mean by conversion to ProRes is transcode. Unless you shot and recorded and edited ProRes, pretty much everything exported as a master file to ProRes will require a conversion.

I also did XDCAM to XDCAM with no frame error.

Just to clarify Ronny, when you say PAL interlaced, you mean standard definition, or just the frame rate?

Hey Tom,

Most of the reports I have read mention an occasional 1 frame error when exporting to a PAL interlaced HD format. In Europe some broadcasters still ask for 50i XDCAM HD.MXF or 50i IMX.MXF deliveries. We don’t do that anymore, we always export progressive ProRes and we don’t see any TC problems when exporting.

Not only for 25i, but also 24P format, timeline settings both prores422 and HQ.
You can easily reproduce that anytime.

You can try 24p prores or hq, you will have the problem

Do you mean 24fps or 23.98? My tests on 23.98 showed no problem.

I am now working on testing 25fps interlaced material as Ronny suggested. The problem has not reproduced for me in 29.97 interlaced ProRes, 23.98 obviously progressive in either ProRes or XDCAMHD.

Finally reproduced it with XDCAM 1080i50 outputting to a ProRes master. The output was one frame long.

Thank you, Tom. That confirms our findings. No problems with 24p here, most of these issues are with XDCAM 50i.

One more test, exported XDCAM 1080i50 from a 1080p23.98 project to ProRes and had no frame error. The lengths were identical. So far only XDCAM 108i50 to 1080i50 is producing the error.

It's no matter with XDCAM.
By the way, exporting XDCAM50i to 23.98p doesn't make sense. It will cause jitter, and we will use hardware to do it.
Both Prores422 24p and 25i, and HQ 24p 25i have the BUG.
Anyone can reproude that anytime.

That is not correct. Just like Tom I can only reproduce this with XDCAM interlaced. For any other formats I cannot reproduce this.

Let me show you the test I just did. I export 3 times master files.
All the codec and timeline settings are Prores422.
FCPX10.1.1, mac os 10.9.3, mac pro 2013
Please look at the picture I just upload,
you can see any one can reproduce the bug anytime, and no matter with XDCAM50i.

By the way, there is another BUG here:
Please look at the right part of the picture I just uploaded, the clip begins at 00:00:00:00
and ends at 00:01:00:00

Why FCPX say the duration is 1 min?
As a matter of fact, the duration is 1min, but the clip should end at 00:00:59:29, so the duration is 1min!

In the image you uploaded the clips begin at 1:30:00 and end at 6:00:01. You have been talking about 25i and 24p. The image shows clips whose names indicate 25fps and 29.97fps. The image doesn't show a duration of one minute. Perhaps you meant to upload a different image.
