[Alex Petrovitch] “I have a feature film exported at PRO RES. I need a H264 version. I tried exporting from FCP7 to H264, I chose “BEST” quality for compression, and it’s 69GB. (Every other time I’ve exported features, I used “good” at they are always under 10GB)”
The QuickTime export from FCP done like this ‘auto picks’ a data rate – which is why this was so large. Generally, I don’t like the “Good” or “Best” because these are arbitrary settings – I’ve never done the research to figure out what it picks – but it’s never ‘great’ at a small size. It’s usually HUGE and looks okay.
[Alex Petrovitch] ” I could just reexport from FCP7, trying “good”, but I was wondering if I could take a PRO RES HQ version and convert to H264, instead of reexporting from FCP7?”
I suggest to most people to do exactly this to make a ‘master’ copy of their work (in ProRes.) You can now take this file and encode it (again) to h.264 or whatever your needs are. The ProRes quality is considered to be mezzanine worthy – great for later reuse like this. Minimal damage. Toss this at MPEG Streamclip, Compressor or your given compression tool of choice.
[Alex Petrovitch] ” I usually use MPEG to transcode from H264 to PRO RES to edit Canon EOS Material, which makes the files much bigger. (As expected) But I tried converting PRO RES to H264 using MPEG, and the file size stayed the same. Huh?”
Footage that comes off your Canon camera is about 50 mb/s. ProRes 422 is about 140mb/s. Your files should balloon up about 3x in size. BUT if you convert from ProRes to h.264 using the method you started with (The Best or Good setting) who knows what you’ll get? The data rates are arbitrary. This is why the files were so large – because the ‘Good’ or ‘Best” arbitrarily picked a data rate near ProRes’s standard data rate.

New! Come see me speak @ NAB/Post Production World! -
Sadly, I don’t think OSX lets automated routing of audio occur.

Make the main user login as a non-administrator user. This will prevent the editors from logging in, upgrading etc.

My instinct is that it’s the RAM or a bad sector of the hard drive.
RAM: AE hits the bad Ram location = freeze
HD: AE hits a cache at the bad spot on the HD = freeze.Check the HD. Boot to the recovery partition and run disk utility on the drive.
Pull half the ram tomorrow. See how it works. Then do the other half.Best,

Matt,
That’s really problematic. You should really fix it for him. When he gets back, make sure to come back to the Cow and help him get his Adobe working. This sideways handling is always a mistake. It’s better to get it working the way it should
In the meantime:

https://www.digitalrebellion.com/compressorrepair/Meanwhile, I took the time to open compressor, throw an HD file in and build an MPEG2 2 ways for you.
1) A true 16×9 setting. When played in a DVD, the DVD player will display it correctly with the correct PAR or add letterboxing as appropriate.
2) A true 4×3 setting (which I don’t think you should use.) It’ll end up compressing the black padding (a waste of the bitrate)Best,

!00% what Craig said, but even simpler: These are already really compressed. Saving space here is a mistake, it’s better to make the investment with more hard drives.
[Marshall Munson] “When I get the files into FCPX they are just so large and take up TONS of space on my HD. I would like to know if I can compress them before I edit them.”
Actually, they’re small. They’re running about 2.5 min to the gig. Uncompressed HD runs about 10 seconds to the gig. You’re about compressed 18:1.
You want to edit these files as is, because:
[Marshall Munson] “My videos are for upload to sites like YouTube and Vimeo”
Which are going to compress your files even further, about 5x more (around 100:1).
[Marshall Munson] “So basically is there a way to compress them but still have good quality?”
You already have it with the files from the camera.

Has to be in the root. You could create a DMG (sparse image, HFS+), put them in there and have writable virtual volumes that you can mount/unmount as you like.

Not sure if this will work, but could you make each card a virtual disk image (DMG), mount them and see if Media Browser then seems them correctly?

[Matthew Bourgeois] “the Premiere and Encore that is on the Mac I’m using does not have MPEG-2 as an option”
That’s not right. Right there is your problem.
Yes, you can pass it off to Compressor as 16×9 SD files (and they’ll be flagged for later on.)
But I’d solve your MPEG2 problem; why even have encore (DVD authoring!) if you can’t create MPEG2 files? Have you run all the Adobe updaters? You might even want to do an uninstall/reinstall. This ‘working around’ the issue isn’t anywhere near as efficient as actually fixing it

What were they shot on? Are you using the full version of Adobe Premiere Pro or the Trial?
Are you using video from FCP? Or from the original card/structure/format?Best,
