Choppy playback in CC, suddenly

Yes, yet another mysterious choppy, jerky playback out-of-the-blue issue.

Premiere Pro CC 7.01, Mac, was working relatively fine for a few weeks on a couple projects. Now, on new project, exact same setup and media as before, I get playback that is fine, then after a few moments or a minute, gets choppy, as my CPU becomes increasingly pegged, as if GPU acceleration becomes disabled with time. Cannot edit when it is like that. I give it a rest for a few moments, can play ok for a minute, then CPU and choppiness creaps up again.

Premiere Pro CC 7.0.1

Mac OSx 10.8.2

Nikon D800 and D7000 .mov files, 1920-x1080 23.976fps, High Quality

Sequence: DSLR 1920x1080x23.976fps

Project: Mercury OpenCL GPU (via AMD Radeon 6770m in Macbook Pro.) No change if switch to Software Only.

Premier Pref/Memory: either Optimize for Performance or Memory, and restart. No effect.

Playback Resolution: 1/2. Always worked before.

No other software running. (Time Machine enabled, not backing up. Crashplan paused or service unloaded did not help.)

When CPU pegs, it is kernal_task and Premiere at top of All Processes/%CPU table in Activity Monitor.

Macbook Pro, late 2011, quad-core 2.5 GHz i7, 16GB memory. Apogee Duet2 audio output.

Source files and cache files and preview files on Pegaus Raid on Thunderbolt. NEC monitor on Thunderbolt. Premiere on internal drive.

No complex layers, effects. Just straight video and 2-4 tracks of audio. So little to no Previews rendered.  Timeline bar is yellow, which always played fine (via OpenCL.) Rendering Previews of a few minute section does not help.

Happens whether doing multicam sequence or simple cuts.

Cleaned media cache (Premiere/Prefs/Media/clean cache.) No Previews to clean out.

Graphics Switching disabled, so always on Radeon.

Only Changes since it was working -

CC app update (i.e. the menu bar thing, but I usually Quit that anyway.)

Indesign CC, Extension Manager update (but never launched.)

More memory allocated to Crashplan (but if I pause or unload that service no effect. And memory does not seem to be an issue looking at Activity Monitor.)

Checked Files on and rebuilt Thunderbolt raid directory (with DiskWarrior, just as general maintenance.)

Apple Timecapsule firmware updated to 7.6.4.

Maybe Java updated to v7 update 25 during that time.

Thanks,

Vincent

Correct answer CRide97

I just solved the problem that I've been having.  I traced the problem back to the audio device I've recently plugged in to my mac through the Digital Optical cable.  I can't say why Premiere was struggling to play nice with it, but as soon as I plugged the device in through a regular line out (quarter jack to RCA) my problems went away.  It's too bad I can't try and monitor true digtial 5.1 surround, but at least I'm back in action for editing.

I hope this helps.

Chances are, you have the playback set a full resolution. Drop it 1/2 or maybe even 1/4.

Anyone ACTUALLY figure this out. 32gb RAM, i7, 8 cores, 2 Geforce 1080, and 1080i GPUs.

STILL get freezing and stuttering as soon as I add a camera transition or a lower 1/3rds. Progressively getting worse for some reason.

I'm stumped. I've tried everything suggested in this forum.

I have to say,

I am spending more time doing IT work on my computer to keep this program running and less time editing. I am sorry, i know you guys are always asking for specks, software and all that.  But your answers to keep this software from doing the most basic things like playback is getting longer and more complex. I am beginning to feel that i have gotten the Windows Vista version of Editing programs.

Here is an idea, try testing your software for a few hundred hours on a computer we all have before releasing it not a adobe headquarters super computer

We are Editors, not IT personal. And before you say we have to be both, no we don't.  It's like asking the camera man to open his camera and rewire it just to get the view finder working.

GUYS!!

I found the problem!!

I had the same thing, so I read CRide97 reply and tried to find what causes it,

Change the "Default Input" to "No Input" and it solves the problem!

Hello,

I just got off chat with Adobe. I am working on a Macbook Pro, 8GB with a Intel Iris 1536MB Video Card.

1- He had me change the Renderer Settings:

     Click File, Project Settings, General, Video Rendering and Playback

          Mine was Mercury Playback Engine GPU Acceleration, and they had me change it to Software Only

          Then clicked Delete Files

          Then Rendered the project (by hitting enter key)

2- He informed me that my video card wasn't quite large enough for HD video (annoying as I just bought this a year ago)

But after following step 1, my playback was completely fixed Good luck

I am currently struggling mightily with this issue myself. It seems to follow no rhyme or reason.

What I can report is that it really, really tanks my MacBookPro completely, slowing down and causing sluggish behaviour in all other apps, even Finder. Shutting down, waiting a few minutes, shutting down again, blowing out all Adobe cache files (if only I could charge someone for this task - it'd be like a p/t job for me!), relaunching Premiere, ad naseum.

NONE of the suggested workarounds has ever fixed this for me.

TIME is the fix - wasting a few hours once or twice a week when Premiere hits this snag, and eventually finding its balance again so I can resume editing.

I remember when I first started using Premiere CS6 - it was like a dream. Never lost its way even once, if I recall correctly. I couldn't believe how reliably it played back my video and audio.

Lost and very frustrated,

Quick clarification: I am on the very latest build of Premiere.

The strangest fix for me, although it is VERY annoying and not a solution! I am on a new 5k iMac and this issue started a few weeks ago. My fix: When the issue occurs, stop playback, then go to file > preferences > audio hardware, then click settings to bring up your Apple 'Audio/MIDI Setup' dialogue box. Close the box (don't CMD+Q to quit it!) ensuring the icon is still active in the Mac dock. Now go back to premiere and hit play on your sequence timeline... Still stuttering?... Now click repeatedly on the Audio/MIDI icon 5-10 times (nothing will pop up because you closed it, remember) and then return back to your timeline and press play. THIS FIXES IT FOR ME... for about 5 minutes. It happens again, I repeat the process.

I have tried this consistently so I KNOW IT IS WEIRD but it works for me............

Premiere is a PITA, poorly developed and buggy leaving Pro users totally stuffed and searching for workarounds just when a deadline approaches.. Totally unacceptable when we pay for the priveledge and have no option but to use their Apps. Out of the blue I'm suffering hopelessly choppy playback in Multicam. The video (XAVCI from an Fs7) plays fine in the multicam source sequence but not in the multicam sequence. I'm using PremPro 9.2.0, a MBP i7 with 16GB Ram, Nvidia GeForce discrete video card and 1TB SSD running Mavericks. Totally by chance I've found that reducing the number of audio tracks in the 'sequence settings' dialogue has an effect. I dropped from 8 tracks to 4 and it plays ok. Upped it to 32 tracks just for a laugh and won't play any audio at all. Maybe the 'audio hardware' thread is the one to follow to solve this nonsense. Is it a RAM issue or more likely poorly debugged Adobe software?

Hi premproisadog,

It may be how you are creating the multi-camera sequence. Perhaps too many audio tracks are being made. Please contact our support representatives M-F 5AM-7PM for troubleshooting this tricky issue: Contact Customer Care

Dear Editors friends,

I was having this issue with video struggling at playback, and I solved the problem changing the AUDIO HARDWARE

Edit > Preference > Audio Hardware (My default input was my capture board and I just clean that and my playback is normal again)

Please try that before you uninstall or do something crazy, can be very useful!

Thanks!

Brilliant!  Changing the Audio Hardware worked for me too!

I have had this issue for the past few weeks and tried everything I could find including reinstalled the programs and deleting all existing settings. The fix for me was annoying simple if not seemingly complete random. By chance I unplugged my USB microphone (Rode NT-USB) and started up Première Pro and the choppy audio had gone. I plan on testing this out some more, but wanted to post here in case it helps anyone else find a (possibly) dodgy USB device they have attached).

I was having the same issues with choppy playback (leading to crashes). Much trial-and-error later I think I've hit upon a fairly easy fix. Most of my sequence preview settings had defaulted to I-Frame Only MPEG. In the Sequence Settings I changed the Editing Mode to Custom, then chose Quicktime as the Preview File Format and the Codec to Apple Intermediate Codec. Seems to play much better with different formats in the same sequence and slightly faster than ProRes.
