Premiere Pro CC 2014 - Choppy multicam playback

So I'm running Premiere Pro CC 2014 (8.0) on OSX Mountain Lion (10.8.5), using CUDA acceleration and everything works fine except for one thing: when I do a multicam edit I switch the program monitor into the multicam mode as usual. However, during playback I'm dropping frames with the video (audio playback is normal). This happens with playback at any resolution, even down to 1/8. Since I've retained the previous version of Premiere Pro (7.0), I've checked it's multicam playback and it's completely normal at full res. After going through and matching all settings in 8.0 to 7.0 I'm really at a loss with this problem, any ideas?

Correct answer RGTV

As I stated earlier, the only solution I've found was to transcode my footage to DNX. With DNX footage I was able to do multicam with 8 angles with no lag. With ProRes footage it would bog down with only 3 cameras.

for what it's worth, (from a novice playing with big boy toys) I notice the GPU utilization will run at ~40% during normal playback. When I start to see dropped frames, the GPU utilization is also dropping in utilization. Stop/Start will usually bring back to normal playback - and normal GPU utilization.

Has there been any viable update to this problem? Multicam playback is still unusable in CC 8.1.

Thanks,

I'm not cutting pro res footage. It's quicktime files from a 7D.

Hi folks,

I'm also having problems. I'm on a Mac with an AJA KonaLHe plus card running OS 10.9.5. My multiclips are 30 - 60 mins in length and the audio is sluggish. I updated to the the latest Kona LHe+ drivers, plugins and firmware and I have the same problems.

When I switch cameras, there is a lag in playback as I switch cameras. I have a 12 core 1.2 with 30 gigs of RAM. I've gone over and over again the settings recommended and no improvement.

Here is one thing that has worked. If in Preferences - Playbackyou disengage the video and audio playback and just play through to your computer and its speakers it works.... no lost frames, no lagging audio. I think there is an issue with longer clips and Multiclip. It kinda defeats the purpose of using Multiclip. I wonder if I can go back to my AJA card playback after I've flattened the Multiclip. What a pain in the butt!! I've wasted a few hours trying to solve this...

Update:

I got a replacement AJA Kona LHe+ and there are less problems. The audio is still buggy but manageable.

There is definitely a problem with how Premiere interfaces with the AJA card. I have followed AJA's detailed instructions

with their latest drivers... blown all of the relevant preferences, reset PRam. Its interesting when the Ted Talks post-production arm were reviewing software to cut their multi-camera talks they considered Premiere but ultimately chose FCPx. Until Premiere repairs their multi-cam function I'd consider alternate programs for longer multi-cam work.

A little late to the party, but having the same issue with MTS files from a cheap camera, but transcoding to DNxHD did the trick

Agreed. I just transcoded footage that was laggy in ProRes to DNX and playback was great. "CompleteAheadOfPlay" shoots up past 300 and stays there. Therefore I'd wager that this is a ProRes issue, or a codec issue in general.

I too am noticing poor performance with Multicam after the latest update. Besides Laggy, Slugglish GUI Response.

There are times when I can click on a clip in a Multi Cam Source Seqeunce and PP hangs to a Not Responding State Show on the Title Bar for about 10 Seconds, but it highlights the clip, also very slugglish like treacle when zooming in on a Nested Multi Cam Nested Sequence, showing high CPU Use.

Anyway the main performance issue for now is the Multi Cam Choppyness.

My system is a Q9650 with 8GB DDR-2 RAM and a GTX 760 4GB GFX Card. Win 7 SP1 x64

The OS and PP is on a SSD 60gb and the video on a internal Sata 2 7200 Drive.

I understand that my system is a little old now, and peformance wasn't the best even with the late version of PP CC 2014 before the update, but now after installing the latest update it has gotten worser.

Like it has already been said in a post above, when you turn on the Multi Cam Preview Monitor, then the playback starts ok, plays smooth for a few seconds, then starts to go choppy, and the frames indicater goes from green to yellow, and keeps increasing on the number of dropped frames. One thing I notice is the the CPU is pegged out all the while at 100%. I am not sure but pretty convinced that this is the cause of the issue.

I am editing 4 streams of HDV 1080i PAL Footage.

If I am going to have to transcode, then what do you reckon would be best format to transcode to for the edit?

I know about the option of making proxy files but don't want to make low res versions that I can't use well enough to judge the focus, as this being a multi cam show I am working on, there are times when some angles are not in focus, or slightly soft focus for a little time whilst the camera ops have been reframing/refocusing.

I am really abit surprised as to why Premiere Pro has trouble playing back multi cam streams, I have recently been using Grass Valley EDIUS and could edit and preview smooth as butter 6 HDV Streams in realtime from the same drive I am using now an Hitachi SATA 2 7200 Drive. I understand that PP is a native x64 bit app, compared to the older EDIUS 6.08 32 bit app. I thought originally that the MPE was the Bees Knees? Is it not?

When I switch back to normal view, then the CPU usage drops back to about 25% and I get smooth playback again.

I know a lot of people are posting and reporting issues with the new 8.1 update, and speak of the slowness and slugglishness they are experiencing since they updated.

I really hope that you guys at Adobe can get your heads around what is causing this issue.

I enjoy using the software but at times like theses I feel like my stress levels are way too high.

Anway, that is my 2 cents

Any advice is much appreiated.

Thanks for taking the time out to read all this!

I just did the update and am still having the poor multi cam playback issue.

I'm on a late 2013 MBPr with 16GB ram, 1TB SSD HD, i7 Quadcore laptop. 2GB graphics card.

Working with Panasonic GH4 4K footage and even at 1/16 resolution the footage gets choppy after 3 seconds of playback.

I cannot edit.

My GH4 is also firmware updated. Running OSX 10.9.5

I experimented with the multicam issue after the latest update. If I tried playback with an existing project it dropped frames as before, but if I started with a fresh project it behaves normally (at least so far). I can't speak to 4K, but experimenting with 1080p in a new project might be a good place to start.

Thank you,

I'll try that..Also, are you by chance RGTV as in Red Giant?

Hey so I found that when you use the edit camera option to change the shot order in a multicam that complete breaks the muticam and makes it sluggish.

Are you running GPU acceleration in your project settings?

Yes, I´m running with Mercury Playback Engine GPU acceleration (OpenGL).

I also try with no GPU acceleration (Mercury Playback Engine Software only)
and same thing. Try to change timeline settings and nothing too.

I´m working with MPEG files 4:2:2 generated by tricaster (SD 16x9 PAL), nothing special I think.

The other concert I edited was in this format too, I dont know whats wrong!

Looks like I spoke too soon. Fired up Premiere Pro CC 2014 to do another multicam edit and started dropping frames. Here's a comparison of the old CC (7.x) version to the new 2014 version (8.x) from the Render System Info (CMD+Shift+F11):

Premiere Pro CC (7.x)

CUDA Render System

Total render time: 0.86ms

Display FPS: 24.05

Target FPS: 23.98

Rendered FPS: 48.86 (This number will start high, then begin to drop as playback continues, not falling below 24)

Total: 127

Dropped: 0 (No dropped frames for sequences of at least 5 minutes or more)

RenderSize: (3840, 1080), Downsample: 1.00

Quality: Draft, Field: First

FramePrefetchLatency: 15ms

InQueue: 137

PendingInQueue: 0

CompleteAheadOfPlay: 132 (This number will increase to 132 at beginning of playback then stay there)

PF: VUY 422 8u 709 ImporterQuickTime (This shows for each camera in the edit, in this case x4)

Premiere Pro CC 2014 (8.x)

CUDA Render System

Total render time: 0.71ms

Display FPS: 24.21

Target FPS: 23.98

Rendered FPS: 36.94 (This number will start high, then begin to drop as playback continues, dropping as low as 21)

Total: 58

Dropped: 0 (Frames will begin to be dropped usually by the 30 second mark)

RenderSize: (3840, 1080), Downsample: 1.00

Quality: Draft, Field: First

FramePrefetchLatency: 554ms

InQueue: 48

PendingInQueue: 12

CompleteAheadOfPlay: 31 (This number will start out around 132, then begin to fall. When it gets near 12 frames start to drop)

PF: VUY 422 8u 709 ImporterQuickTime (This shows for each camera in the edit, in this case x3)

I've racked my brain over this issue, we really need someone from Adobe to look at this thread.

Hi everyone!

This problem is with me too. I just can't edit multicam, playback is frozen always.

I'm in a new project with a concert and have 8 cameras. With this new version (CC 2014 v8,0,1) its total impossible.

We installed more 3 hard drives thinking that the playback will get better but no way.

Last Christmas in première cc v7 I edit other concert with same 8 cameras and no problem, multicam works well.

The problem must be this new version. Adobe have to fix it!

Just wondering, what OS and what graphics card are you running?

OK, I think I may have solved this problem:

Goto Preferences--Playback

Make sure "Enable Mercury Transmit" is checked

Below that make sure that "Adobe Desktop Audio" and NOT "Adobe DV" is selected

I've just tested a 5 minute multicam span with 4 cams and didn't have a dropped frame on full res. This is with CUDA enabled, and using CMD-Shift-F11 to check for dropped frames. I will update this thread if I have any further issues with this, but so far so good.
