Excessively large files with Compressor on High Sierra

Same problem here.

We have trash preferences of compressor and did not help.

We have 4 Mac Pro Late 2013

3 of them have been updated to High Sierra and all of them have that problem. No matter wich presets ( Default or Custom) we use, the exported file have a huge file size than estimated.

The remaining Mac Pro with Sierra compress with the correct estimated file size.

I believe if one waited for the High Sierra update for the video pro apps next week just before the FCP Creative Summit in Cupertino, one would get an app that functions properly with HS. There are a ton of issues with all video pro apps and HS at this time, contrary to the statement Apple posted saying they're already compatible. They've not had HS updates yet, one more week, until then, it's all just beta testing...

I have exactly the same issue on my Late 2013 Mac Pro.

However I have been told by a high profile non-Apple person that:

Apple is working on a new version which will be out in the next few weeks

So that sounds like the answer.

Hope we can wait that long.

Thanks, its good to know there is a new version of FCPX around the corner - so a new version of Compressor looks highly likely too.

Has anybody found a workaround for Compressor in the meantime please?

Thanks,

Andy

Bingo - For my needs I have found a perfect workaround for compressing to 1080p at 15Mbps, suitable for Vimeo and Youtube.

1) Export master file from FCPX

2) Import master file into iMovie and Share to Vimeo or Youtube

Job done (for me at least)

Hope this helps somebody

Hi,

When I previously said I have found a perfect workaround for compressing to 1080p at 15Mbps, suitable for Vimeo and Youtube.

1) Export master file from FCPX

2) Import master file into iMovie and Share to Vimeo or Youtube

....may I expand on this.

You can also export a perfectly compressed file to your Mac and select the bit rate and either quick encode or multi pass encode settings.

I imagine this is what Apple would have advised us if the information had been reported on this thread.

I hope this helps.

Yes, High Sierra have all my Compressor presets worthless...the files always be in the range of 60-90 mbps after export - whatever I've set (often 10-16 mbps).

I've notised after testing that it's only when you have "multi-pass" - change the preset to "single-pass" and it will behave properly. I hope the Apple tech-people have notised this & I hope they fix it soon (I often want multi-pass :-).

Not yet - but I'll be surprised if this update fixes this OS/Compressor bug. It's nothing about it on the update info anyway.

Update: My MacPor tower also crashes and makes the MacPro to restart when I compress jobs longer times - I don't know what happens, but everytime I try to compress hours of files the MacPro is restarted whern I come back and the job is interupted and the job does not continue when I launch Compressor again and I can't delete the jobs from job-list...only if I go to the "history"-folder in the Compressor-folder in Application Support-folder...

This is a mess.

I'm not prone to hyperbole but it's kind of inexcusable that High Sierra is not stable with the Mac Pro 2013 model. I mean, they have to be shipping new Mac Pros with High Sierra right??

PS- there's another easy to replicate issue with this combination when you have a dual monitor configuration. TL;DR, if you have both monitors plugged into your Mac Pro 2013 and the display goes to sleep, the system will not wake up the monitors again and you have to force a restart. This is a mess, indeed....

This thread is running for almost three months by now, and Apple has not responded - except for telling one user, that they could give him a complicated workaround. And it looks like they did not even publish that.

And they are selling these tools for professional use.

I really like the workflow of the three Video tools, but this is more than annoying - FCPX is crashing regularly on my HS-System too.

I always (at work) wait 1-2 month untill I update to "new" OS - so I runned Sierra fine until a couple days ago when I updated work machines to High Sierra - that's why this is new for me (I wish I had done morw research before updating...but it's hard to fins stuff if you don't specify it and this thread I would never have stumbled on). It's a sad thing that Apple handle proof like nothing...they update iPhones with the speed of light when a single little bug is reported. :-D

I'm on 4.4, but Compressor still delivers very large H264 files that don't follow the bitrate limitation I've set.

This is on a 6-core 2013 Mac Pro running 10.13.1

I'd update to 10.13.2 to see if that makes any difference, but 10.13.2 has a GPU bug that causes problems in the video post production applications I use.
