Am I going nuts? Inexplicable file size reduction!

[Robin S. kurz]

I’ve asked someone at Apple about it. I’ll let you know if and when I hear back.

Thanks for the effort, RK.

If you click on the “Change” button next to QuickTime settings, what is the Quality slider set to?

Best…

On both machines?

[Walter Soyka] “On both machines?”

Yeah, you’ll want to check that. Because that’s the only thing I’ve been told could possibly affect the compression levels, since Compressor doesn’t support profile changes other than Photo JPEG versus Motion JPEG, but rather just different quality/compression levels via the slider. So really that’s the only thing it could be.

I guess this will remain a mystery forever. I just created a new photo-jpeg setting again on both machines following the exact same procedure. Opened Compressor, new settings, change QT setting to photo-jpg, change slider to Best. That’s it.

Then I exported a 6 second UHD clip from FCP X on both machines using this new preset.

On my MB Pro (running Compressor 4.2) I generated a 675 MB file with a data rate of 894 Mbit/s

On my iMac (running Compressor 4.2.1) I generated a 47 MB file with a data rate of 62 Mbit/s

Freakin’ frustrating as hell…

(I think I figured it out: it’s Apple’s way of saying “Abandon photo-jpeg, embrace ProRes!”)

I’m told they’re unable to reproduce and would need screenshots of e.g. the window with the slider settings to move forward. Basically any and all details of all the settings used that you can provide via screenshots.

Seems like the data rate has been drastically reduced when using the latest version of Compressor. I also upload to stock sites and have noticed this change. Not sure if it’s a bug but it’s already April 2016, so has anyone figured out the cause of this or a workaround? I’d like to keep the data rates high to keep image quality up so until then we may have to settle with other software.

[Robin S. kurz]

So you’re saying that the quality is factually worse, or you’re simply assuming it is?
