[Al Perry] ” I have a CC subscription and have been conscientious about OSX updates and every single “upgrade” has resulted in demonstrably worse performance. I can’t see this trend changing with Mojave. I appreciate the new features of Premiere CC but not at the expense of a responsive interface. “

Premiere and the mac OS keep upgrading software but by the looks of your computer specs you haven’t been upgrading your hardware. And as a result, you’re experiencing sluggish performance.

A minimum of 32 gigs ram, a GPU with at least 4gigs, an i7 CPU and a fast raid is what will allow you to run Premiere efficiently. If upgrading isn’t an option then work in proxy mode until you have an opportunity to upgrade.

Trevor, I added my vote for that request. The bummer is that the voting numbers for many of the requests on the user voice are woefully low and therefore I doubt that the Adobe Premiere team will look at them as top priorities. In order for the user voice site to actually affect change there needs to be a much larger user base actively involved.

Tim, thanks for the thoughtful and exhaustive response. Now with all of that perspective, the request seems unnecessary so I’ll rescind it.

Transcoding H264 into either Pro-res or DNxHD/HR will greatly increase overall Premiere performance. This used to be potentially problematic because of the large file sizes created by these formats but with storage being cheap it’s now a non-issue.

What’s preventing you from live switching the event? I would discuss options with the client.

You’ll need to work from a raid and not a single drive in order to get decent data thruput. A four drive TB2 raid can handle all types of media. your ssd is working because it has very fast thruput but that’s putting a ton of stress on your imac.

Unless you work all night thursday night why not just batch transcode overnight?

I would test FCPX to see if it might better handle the avchd files.

False advertising has led many to believe that Premiere can work with any type of file just by importing it. That is true in that Premiere can technically playback any file type but Premiere will struggle mightily with file types that aren’t intended to be edited natively.

Any and all variety of H264 media is not edit friendly and therefore Premiere will struggle with it. And whatever format you work with the files need to be on a secondary drive and not your OS drive.

The proxy workflow requires transcoding as well so you won’t save any time that way. Hard drives are cheap so if FCPX doesn’t handle the AVCHD files any better then your best option is to transcode all of the raw media. If you’re working with pro-res files you’ll have zero issues and your computer will work optimally.

I’m not sure whether time allows but ideally you wouldn’t be editing from the avchd files due to the file spanning as well as the fact that it records in H264 format which is very CPU intensive. In order to smooth out your workflow I’d suggest:

transcode each of the ten angles into an edit friendly codec-i.e., Pro res or DNxHD. Import those transcodes into Premiere and sync those 10 angles to your master audio track.

A few ways to improve sync: jam sync the timecode of the 10 angles and your master audio recorder or send the soundboard audio of the event your shooting to all ten angles. If your 10 angles are just capturing audio from the camera mic you’ll likely run into sync problems.

John, what are your system specs? I noticed that you also posted about having repeated audio problems.

If your Premiere system is running normally you should have no problems playing back or syncing audio.

One major flaw of Premiere is that it operates separately from whatever audio selection is made in system settings and that’s frustrating. You have to select your audio output in the Premiere preferences and you also have to make sure that the same output is set in your system prefs. Many people have made the request to Adobe to fix this but for the moment it is what it is.

I’ve noticed on this forum and others that many people have issues with syncing inside of Premiere and that’s very confusing. I’ve yet to run into a file that Premiere cannot sync properly. As long as you have usable sound on each file you should be able to highlight whatever clips you want to sync, right click and select “create multicam source sequence” and then it should sync.

In order to clean the slate I’d recommend that you select all of your clips in the bin, right click and select “disable master clip effects” and then apply the amira lut manually.
