I'm having an issue with FCP X 10.3. Can't find a solution in any forums.
I'm working on an 84 minute feature film. All looks good on the timeline, and when playing back from the timeline.
But when I Share/Export to create my movie file, I get random 'glitches' upon playback where the video breaks up or pixellates for two or three frames. And this is almost always on a cut transition between two clips. The outgoing clip and/or the incoming clip break up into a brief pixellated image, then all is normal. To experiment, I've exported as Pro Res or H264; regardless, the same thing keeps happening, and not always in the same spots with the same clips.
I have gone back to reimport the original clips, using them to replace existing clips. Sometimes that works, sometimes not, and often times these 'glitches' occur at entirely different spots the next time I Share/Export to create another movie file.
I'm running out of options. Can't find a solution. PLEASE HELP. Thanks.
