Activity Forums Apple Final Cut Pro X Unusual FCPX problem – red line in timeline render bar

  • Doug Metz

    Further Update:
    I was able to reliably reproduce the problem in any other project by simply adding preroll to the TC setting. It gets confused rolling through zero.

    Edit – tested on several projects with different frame rates. When preroll is added, you may not see the red bars initially, but simply disabling / re-enabling various clips will reveal the red bars.

    [Doug Metz] “When I changed the start TC from 23:59:54:12 to 00:00:00:00, everything functioned properly and all red bars disappeared. I was unable to make them return after this change.”

    Doug, thanks for this. I confirm this on my machine and copy of the library.

    However there is apparently a separate problem whereby certain timeline ranges will not render or keep showing render dots. I see this on clip “Galaxy cam1_ProRes 422 HQ”. This might be the overlayed Motion title, which shows the “missing” yellow exclamation point.

    As you suggested, Hamdani could try resetting the project timecode to zero via project inspector>modify>starting timecode, then evaluate. If that fixes the red line issues but there are remaining problems, then state what those are.

    There are a few render tracking issues whereby the render dots won’t go away if the clip has certain effects or titles, but it’s unclear if this is that problem.

    As noted above, I was able to reproduce this in several of my other Libraries / Projects. I suspect you’re correct regarding the missing title over the Galaxy cam1 clip.

    I’ve submitted a bug report via the FCP > Provide Feedback mechanism.

    I’m so glad you jumped in Doug, it seems you’ve nailed it.

    I can confirm that resetting the project starting timecode to all zeroes consistently eliminates the red render error line across several affected projects in several updated libraries. It also fixed some other weirdness including incomplete render portions of a timeline that would remain unrendered and the mysterious jumping compound clip described in an earlier post.

    It’s the last thing I would have thought of, I’ve been offsetting the project timecode to allow for colour bars and black preroll for years.

    Thanks for submitting the bug report Doug and Joe, I can confirm that all clips across several libraries, including the one uploaded, all render fully, as expected.

    Thanks so much to everyone for your time and effort in helping to track this down, it’s a huge relief and I am most grateful.

    Joe, I tried your suggestion about opening the Red Line Edit 08 library in FCPX 10.4.6 via XML export / import with the original project timecode offset and can confirm there was no red line issue (running on macOS Mojave).

    Thanks!

    That is good, but if you can run 10.4.8 there are definitely performance improvements. Long term, you don’t want to get stuck on 10.4.6 as the new versions roll out. When I tested 10.4.8 using Doug’s suggestion of resetting the project timecode to 00:00, it seemed to work.

    However you have a project to complete so do whatever you think is necessary for now.

    Out of curiosity, I tested a bit further by adding more time to the preroll.

    I wanted to see if the red indicators would change based on the location of 00:00:00:00, and in fact, they do. I reset the start time to 23:59:35:00 so that the TC would roll over in the middle of the timeline to confirm. Red only shows after the zero mark. Tried a few other start times to verify successfully.

    Definitely a timecode bug.

    [Doug Metz] “Definitely a timecode bug.”

    I can confirm your findings about setting different pre-roll timecodes.

    After applying 00:00:00:00 as the project start timecode to projects across several libraries all unexpected render / red line issues and other quirky behaviours have been eliminated, although the option to change a project’s starting timecode for pre-roll purposes is effectively redundant.

    I also submitted a bug report via FCP Feedback and pointed to this thread for further information. Perhaps others can consider doing the same to help bring this to Apple’s attention.

    Great, back to work with confidence in FCPX restored. Thanks to all!

    I have this happening too…not sure why, but I have not experienced any performance hits at all..
