Dropping Frames Randomly

Report · Mar 24, 2017

Hi!

During both preview and playback (with only marginal white balance edits), the video drop frames, and sometimes goes to black.

Sometimes I am able to do real time heavy edits, and suddenly 90% of the frames is dropped during preview on 1/16 quality. I don't understand what's happening. It's so random, but yet super annoying. I look at the performance when it happens. I am only using 10GB ram, 10-20% of the GPU and 70-80% of the CPU. The harddrives are only at 10% speed capacity. So I don't think there is a hardware issue. I have tried enabling/disabling Cuda and the .h264 compression.

My computer is a Windows 10 64 bit, 32GB DDR4 ram, inter core i7-5820K 3,30 Ghz. Three SSD drives and Nvidia GT 980ti.

Any idea whats wrong?

I usually edit. DJI Phantom 4 pro +, Phantom 3, Sony a6300, GoPro, 5d mk2. I use both the 4k settings and the 60fps settings. However the issue appears on all media.

thanks!

Are the frames only dropped in the preview? Or even when rendered? When it happens does it fix itsefl or do you need to take some sort of action?

Something else to check, what version on Nvidia drivers do you have installed and what version of Premiere are you running?

Hi! Thank you for answering.

They are dropped both in preview, timeline and source monitor. Every time i render footage I get yellow "media pending" forever. I have to put another clip on top and then remove it again. Then I can see the footage rendered. When the footage is rendered it looks to be playing fine.

Nvidia: I believe I have installed the latest update.

Have you verified the project frame rate matches the footage?

I've had that happen many times and it can give that type of symptom, along with placing frames in weird places too (often in AE though).

Hi! Thank you for your replay.

You might be on to something. However I use both, 25, 30 and 60fps in the same timeline.

It also happens when I preview some of the source footage to decide what to import in the timeline. I guess the fps solution is not relevant to that issue as you can't change the fps in the source monitor?

Thanks!

Yeah, premiere doesn't do well with mixed frame rates so I suspect that's the problem.

Premiere Pro actually does quite well with mixed frame rates. Premiere Pro has never done "well" with H.264 media, and is even worse with such media at 4K resolution.

Premiere Pro does significantly better with Cineform files. Hence the Proxy suggestion.

Thank you all for the feedback. Really appreciate it!

I don't understand how it did not now about proxies. It really helped, and its something I have been waiting for. Thanks a lot!

I am now able edit fast. The original problem still persist. With my computer specs I belive I should be able to playback most of the media just fine.

Would you always convert to Cineform or just use proxies?

I do. I find the editing experience much improved.

Hey Jim,

Appreciate your reply myself too. For me, one of the most frustrating Premiere features has been not being able to change the frame rate after a project has begun. I remember this a couple years ago and asking in forums and once started, it can't be changed. So, hearing that it does well with mixed frame rates sounds great but could you explain? Just curious now because I've seen issues when the frame rate of the project did not match and different clips with different frame rates caused me difficulty. Maybe it's improved since then.

I know for a fact in AE, a comp with incorrect frame rate may have problems. It's never 100% but one indication is a frame from one clip pops up in another for no apparent reason. In every case I've seen that, it was due to a comp that had a mismatch rate to clip setting. At least that is easily fixable.

That hasn't been true in a very long time. You need up upgrade to CC.

Jim,

Thanks. I've been on CC since the beginning actually, though I still use the 2014 version. When I went to 2015, it seemed to give me problems so I stuck with 2014.

Good to know though.

For that kind of media, I recommend using the new Proxy feature in PP. Stick to the included Cineform presets.
