Question

How to make Premiere perform better, use all RAM available?

I'm new to Premiere and still learning. Premiere constantly hangs, drags, virtually freezes up and makes editing somewhat torturous. Even though I have 32 GB of RAM installed, my OS Activity Monitor app shows that Premiere is using only 1.5 GB at any time. How to get Premiere to use all the RAM I have?

More info:

I'm compiling 1280x720 sequences from a wide variety of sources, mp4, wmv's, m4v, avi's. Most of these live on an external drive with USB3 connection.

My projects typically have between 3 or 4 and up to 25 different videos imported, some high-res, others scaled up to fill the frame, edited in to several hundred clips with video and audio tracks.  Also lots of split screens and motion effects.

I understand this kind of project would be processor intensive.  I routinely have to wait between 3-8 minutes while Premiere "does its thing". Each time I move to a different part of the sequence to work -  and most of the time when I push the space bar (play) - nothing happens at all, until I save, which takes 5-10 minutes. Premiere doesn't even give an alert that it's having problems, it just stalls out. When I come back a half hour later, often its ready to go again.

Rendering the entire work area takes all day and then the next time I go to edit, the same delay issue pops up again.

Is this just what Premiere editors have to suffer through? Does Premiere have a cap on how many source movies it can import, or how large the file size? Also, do I need to have a scratch disk?

Tips for optimizing through-put for large projects with all the bells and whistles appreciated.

    Ok changing the Optimize Rendering setting offers no improvement.

    The program just does not seem to be processing the information correctly for me despite the large amount of RAM available. This  screen cap shows Premiere with the "Rendering Required Files" dialog box open, preventing work from being done, and the Activity Monitor displaying that Premiere is using only a small fraction of the RAM available. This Premiere dialog box pops up every time I move around the timeline to work somewhere else.

    Another common instance of malfunction - After "Rendering Required Files" completes,  I press play/spacebar, and the playhead advances and the audio plays, but no video plays, likely because Premiere isn't using the RAM available. After 3-5 minutes, the video resumes.

    Can anyone offer add'l insight? thank you!

    ‌It looks you are using a lot of .MOV formats, that require the QT 32 Server extension. That is a 32 bit extension that can not use more than around 2.5 GB of memory out of the total 4 GB, even if you have 32 or even 64 GB installed.

    you can try setting the memory preferences, "optimize rendering for" to "memory". also this Premiere Pro CC, CC 2014, or 2014.1 freezing on startup or crashing while working (Mac OS X 10.9, and later)  premiere will mostly uses ram to hold previews of the timeline during playback. so the ram usage will change depending on the timeline media and whats being done.

    i would say no, this is not what most premiere editors go thru, or premiere wouldn't be around any longer. i also dont know of any limitation to imported clips, size or number of. many do use a dedicated scratch disk, depending on the speeds of disks available, some use scratch on a drive being used for other things as well. having the project file and cache/previews all on a fast internal drive should help premiere not have to transfer as much data over the usb3. it looks like the cpu speed of those xeon's are on the slow side, but if you can check the computers resources while premiere is stalled/hanging, you can see if perhaps the cpu or usb3 drive/transfer is maxed out.

    there was a similar post from another user a while ago, that had a very large project on multiple usb3 drives, he noticed a new project with a few files on an internal hdd ran smooth. he was never able to transfer all the media to internal drives, so we don't know if that would have fixed it. he also had a massive project file itself, which seemed to be caused by data from the warp stabilizer effect storing data in the .prproj file. some people doing long timelines, like over an hour, will split up the timeline via sequences or projects, and combine them later in a master timeline, to avoid large project issues with premiere.

    Thanks for taking the time to answer Ronin - appreciate it. I'll try setting the Optimize rendering to Memory and see if that helps - although the default Optimize for Performance seems likes the obvious choice. And I will look through those links. My videos are up to 2 hrs long, so I suppose breaking them into parts and reassembling them (somehow) is something I might have to live with...

    I have Premiere Pro 6.0.0 - not CC version.

    oh, kinda missed you were on cs6. there is a new method in CC to join multiple projects, but i think for cs6 you will have to stay in one project and nest your multiple sequences as the master timeline to reassemble them.
