Adobe Premiere Pro CC 2015 very slow, lagging preview

[michaela26687487]

Hello,

I'm currently facing a very frustrating issue in Adobe Premiere Pro CC 2015. I'm trying to edit 1080p, 30 fps footage with a bitrate of 20Mbps but editing it is impossible for me at the moment because Adobe Premiere is too slow.

I import the footage, and when I double click on the footage for it to show up in the "source" window, it just shows the "media pending" image/message. It takes minutes for the thumbnail to load, but even then I can't properly scroll through the video and figure out which parts I can use to put in the sequence. It only displays on frame from some part of the video and not the one at the marker that I move. Even if I cut out some arbitrary portion of the clip on put in a sequence (even though I can't tell what I'm working with), I get the "media pending" image again for the thumbnail in the "program" window. After a real thumbnail loads, I press play, but it doesn't even play the clip! The play button doesn't even always become the stop button. If I wait longer, only audio plays, but that single frame remains even though the marker runs to the right, meaning that the video should be being played. Pausing somewhere later, it takes minutes again to load a frame, a snapshot of where I paused.

System Specs:

OS: Windows 10, 64 bit

CPU: AMD FX-6300 at 3.5 Ghz

Graphics card: AMD R9-380

RAM: 2 x 4GB DDR3 in dual channel

Storage: 1TB SSHD, 7200 RPM

I've edited videos on less powerful machines without problems, so I can't image specs being the issue.

Any ideas of how I can fix this issue? Thanks in advance!

I had the same problem. Try disabling "Enable accelerated Intel h.264 decoding" option in Media tab (preferences).

[michaela26687487]

I can't seem to find that option anywhere. We may be using different versions.

[jonartb95017075]

Basiaclly This is a problem in the Preferences.

Click "Edit > Preferences > Media" and disable/uncheck "Enable accelerated Intel h.264 decoding"

(Make sure to restart premiere after)

This worked for me

Yes, I see there are several threads regarding the sluggish performance of the latest upgrade.  I was having the same issue with a major project and thought that Adobe screwed up big time!  After much troubleshooting, happily, pawelw2199727 seems to have the answer.

In the preferences dialog box, disable or uncheck the box "Enable accelerated Intel h.264 decoding (requires restart).  It's just below the checkbox for "Enable proxies".

That did it for me.  Thanks pawelw2199727!

Disabling accelerated Intel h.264 decoding is not a true solution. In fact, the option description does not match with preview problems...

It should get fixed with an adobe patch

[Matt Young]

Add me to the growing list of users for whom disabling "Enable Accelerated Intel h.264 decoding" returned Premiere to a workable state. 

Is there anyone with any theory as to why having that box ticked would cause footage to become unable to playback?

My specs:

Windows 10

Premiere Pr 2015.3

Editing .mts files (1920x1080 @ 25064kbps)

Intel Core i7 6700

32GB RAM

NVIDIA Quadro K2200

2TB Seagate ST2000DM001 SATA drive (for footage)

500GB Samsung SSD 850 EVO (software)

[michaela26687487]

Sorry for the late reply, but could you please tell me where you found this option? I can't find it anywhere.

[OlivierA]

You will find it there :

Preferences > Media > Enable accelerated Intel h.264 decoding

dennisv2476103​ : Yes, clip thumbnail display also very slow. Problem solved for me by disabeling Intel h.264 decoding.

[dennisv2476103]

on a mac we dont have that option. So now i'm wondering how to solve this on a mac.

I've been struggling for a few weeks. CC 2015.4/10.4 was awful, leaking away all my RAM. Reverted to 2015.3/10.3 and it was better but long clips were taking ages to preview. I went to: Preferences > Media > Enable accelerated Intel h.264 decoding and unchecked it. Now much, much better. Just wish I could understand why.

[randyalan99]

This worked for me. Was having issues after the update with very sluggish performance, and even Red Frames appearing on my footage. After disabling accelerated Intel h.264 decoding everything seems to be working normally again. Thanks!

[anitafuxmanbass]

So simple adn it worked, I tried so many things before this!! Thank you!

[michaela26687487]

Update: Basically, my problem is that when I scroll through the footage, it takes a long time for a thumbnail to generate and see where I am in the video.

[cmelton]

Space bar playback isn't working hardly at all. Almost broke my keyboard trying to get it to work. Very buggy and slow during previews...

[iLuh]

I wrote a similar thread about this subject and I realize that a lot of people are suffering this after 2015.3 update

After update to 2015.3 - Worse preview performance

[michaela26687487]

I guess there's nothing to do but wait until it gets fixed. Almost a relief.

[UniqueName35]

Disabling accelerated Intel h.264 decoding worked for me. I was just about to revert back from 2015.3 to the previous version as the preview was extremely slow (basically standing still). I unchecked the accelerated Intel h.264 decoding and it now behaves MUCH better.

[JCSPed]

I cannot find this option, is this a Windows only feature?

[UniqueName35]

I do not know. I use Windows and it's under Preferences > Media > Enable accelerated Intel h.264 decoding
Third option from the bottom and it requires a restart.

Br.

[Snap47]

Yes, I believe it is a windows only option.

[danp20173640]

I am not finding this option either and am on a Mac. I think it's a PC thing.

[danp20173640]

Has anyone found a fix for mac based adobe?? Everything is really slow after this update and it is actually stalling when my media is loading. Adobe please fix this!!!

[Kevin-Monahan]

Hi danp,

Check out this post: Re: Premiere Pro 2015.3 problems

Copy/paste items into a new sequence.

Also try "Software Only" mode in Project Settings.

Thanks,
Kevin

If your mts footage is lagging on Mac, you might be experiencing the problem for a different reason.

On my wimpy 2012 iMac, I had no lag at all with 1080p MTS footage in Premiere CC. But on my super-beefy PC, mts footage had serious lag. The fix from pawelw fixed that.

Interesting sidebar: my wimpy iMac will not play nice with h264 footage at all (super lag), but my PC handles it fine (before disabling the h264 checkbox remedy for from pawelw anyway, which I suspect will need to be re-enabled next time I edit h264 footage).
