I'm trying to export the project I'm working on, a 4K project shot with an anamorphic lens giving a 2.35:1 aspect ratio.
Final size should be 5076 x 2160
Both Compressor and FCPX fail almost immediately whenever I try to export with these settings. If I try and export with a scaled version, 4096x1742 it exports without any issues. The problem with this is that Youtube/Vimeo, etc.. do not interpret the file as a 4k movie.
Has anyone experienced this before? Any recommendations/suggestions?
I just now created a project 5076 x 2160 using custom in the project settings. I dropped a 1080 clip into it and selected spatial conform to fill the screen (I did not have a 4K clip handy). FCPX exported the master just fine without any problems.
I assume you setup the project for those custom dimensions. What error does FCPX display, if any, when it fails?
Also, have you tried the 5K project settings (5120 x 2160) which is roughly 2.37:1 ?
"The SMPTE standard ST 2036-1, “Ultra High Definition Television — Image Parameter Values for Program Production”, defines a family of progressive image sample structures for Ultra High Definition Television, with resolution 3840 x 2160 (termed UHDTV1) and 7680 x 4320 (termed UHDTV2), with an aspect ratio of 16x9, and with RʹGʹBʹ or YʹCʹ Cʹ colour encoding and digitalrepresentation83. The most recent version was approved in October 2014.
Colorimetry is defined consistently with BT.2020. In addition, for UHDTV1 at frame rates up to 60 frames per second, BT.709 colorimetry can be used. The transfer function (‘gamma’) is consistent with BT.2020 and BT.709."
Let's not let this thread devolve into nitpicking who's correct about UHD, it honestly doesn't matter at all.
I really appreciate everyone taking the time to test file settings and helping me learn about H264 limitations. I hope this will be useful to others in the future and a chirp fest at the end of a productive email isn't going to prove useful to anyone later on.
