Fail during 4k anamorphic export in FCPX and Compressor

[Noah Kadner]

Not sure how you do this without a hard letterbox. i.e. 4096X2160 with black bars top/bottom.

I’ve output bigger and odder frame sizes from FCPX without any issue so it should output without a crash but if this is for YouTube then 4096 x 2160 is the widest you can go if you want it to be recognised. YouTube actually recommend UHD as the maximum so 3840 x 2160 would probably be even more likely to work.

Hi Noah,

I think I may have been unclear in my original message.

To clarify, I’m not looking to add black bars or to matte my video, the raw, out of camera footage is 3840×2160 with a 1.33x horizontal squeeze, 5107×2160.

For some reason Compressor will not process a full res export of my footage. However, if I scale down the export to 4096px (w) then I can get my 2.35:1 as a 4096×1742 file, so I’m losing roughly 20% of my max viewable size.

I’m wondering if anyone else is able to export a video of 5107px wide or if there’s a bug in Compressor that fails projects that are too wide.

Hi Jeff,

Thanks for jumping in to help me. Would you know off hand the largest or widest pixel video you’ve successfully exported?

I’m now also trying to think beyond youtube for offline consumption and why I’m seeing failures.

Do you think it could be hardware related?

I’m currently testing exporting at gradually increased file widths. I’m up to 4500px wide and is at about 85% on the progress bar without failing.

I’ll share my finding if that’s helpful.

looks like youtube’s 4k image size limit is 3840×2160. go to this page can scroll to “Resolution and aspect ratio” for more info:

Hi James,

If you take a look at the comments above you’ll see the issue I’m experiencing in more detail.

Thank you for taking the time to try and help me through this.

The widest was about 10k pixels but the height was only about 1k from memory.

I’m not sure how long a project you’re trying to output but I just tested 10 minutes at 5076 x 2160 and had no issues on my 2013 Mac Pro and my 2013 Macbook Air is at 60% and showing no signs of an issue either.

I wouldn’t rule anything out but I think it’s more likely codec or software than hardware if my Macbook Air is chugging happily along.

My final video will be under 3minutes so if you’re able to export with that setting and the 10k setting it eliminates width restrictions from possible issues.

My FCPX and Compressor are both up to date and I’m running mac osx el capitan 10.11.2

any ideas of where to start crossing off possible software/codec issues?

I succesfully exported a 4500px wide version which is better than the 4096px. It got to 80-85% easily, the last 5% took about the same amount of time as the first 85% did, slowed down significantly with the fans starting to get noisy.

I’m now testing 4698×1999, currently at 80%.

it sounds to me more like you’re hitting an issue with a video effect towards the end of the clip. Maybe you’re using something that isn’t 4k+ capable and it’s slowing the system down and crashing?

That’s just a random thought but might be worth taking look.
