Lagging when using proxies

Hello,

 

I've been using Pemiere Pro since 2018 and recently i use the Proxies workflow.

I create Prores Proxy at 960p and clicked the proxy icon. 

 

When Scrubbing with proxies enabled, the speed is GREAT. The moment i enable Lumetri it cripples it.

On the other hand if i import the _proxy.mov file directly it works perfect with and without lumetri.

 

Proxies ARE LINKED to the mp4s  they just cripple when enabling Lumtri (and possibly other effects)

Same Proxy file imported flies.

 

Any suggestions? I am tempted to work on the proxies and then swap them out later.  Surely it shouldn't be like this?

Hmmm ... that's odd.

 

Make sure it's using the proxies ... they should show as "attached" in the Project panel's List view, and of course as below, the Toggle Proxies icon should be blue to be "active" ...

Toggle Proxy 5 Lumetri ON.PNG

 

This clip has two layers of the clip itself, and five total instances of Lumetri applied ... one to the base clip, one to the upper track, three on the adjustment layer. There's four separate HSL keys involved, a ton of HSL curves, some masked instances of Lumetri ... and it plays back without issue.

 

These are made from the BMPCC4K media using the included ProRes 422 1024x540 preset.

Yes it resufes to scrub with a single instance of lumetri enabled.  Proxy workflow is working/linked and enabled.

 

Importing the Proxy file itself works flawless. (low res prores)

 

I'm giving up and going back to old proxy workflow.

I'm wondering if when you have proxies active and apply Lumetri, it's wanting to apply the effect to the Original media and you are getting the slow down. One way of knowing this is to create your proxies with a filename or timecode overlay, then attach those proxies as per the normal proxy workflow, then apply lumetri and see if the original video is being toggled back on (even while you have proxies enabled)

Ok i just did that, And with Lumtri enabled it stays the same using the proxy file. but scrubbing becomes VERY laggy.  Original footage is 4k and i need a low res 960p to edit.

Disabling Lumtri or "all effect" icon.  and it flies.., so Proxies ARE working  (sort of)

I just tested this as well with some 4k footage and performance is ridiculously better using the proxy. How exactly are you making the proxies and what settings are you using? For my test I tried using ProRes LT proxies at the same resolution as the 4k media (but a lower bitrate) and they worked just fine.

You got all the way down here and someone should probably ask what your hardware is?

 

I'm on 2020, win1903 and I just tried it using cineform proxies with timecode burn and Lumetri is applied, proxies still playing with the color correction and all seems well.

His hardware is irrelevant if the proxy plays fine by itself with and without Lumetri. Only when it's attached to the high res media does he get the slow downs with the proxies. He's having a software issue, not a hardware one.

Gee Jeff, can we at least know if it's a mac or PC and perhaps which version PP he's on?

 

If it's software, it's seems that would be good to know...

Thanks for your support. 

 

Here you can see that the proxy file with Lumetri is YELLOW and scrubs GREAT (prores proxy 960p). But the mp4+proxy turns RED and is crippled.

I cleared both cache folders and ptx folder and rebooted Windows PC.

Discribe your proxy workflow because you dont drop proxy files on the timeline.

On a side note if you are using Warp Stabilizer it will use the original footage.

I dropped the proxy to prove that they work fine and it's not a PC bottlneck.

 

Otherwise  I used Ingest Proxy with a custom prores 960p match source via media encoder. They are linked and enabled and scrub great untill i drop an effect. It then turns red. 

 

It's like proxies get disabled. BUT i used a time code overlay and shows that was not the case.

It's a mobile AMD radeon 4170. It's not the issue.  Importing  the prores proxy +  effects works just fine .

 

I can't understand why line turn red for the mp4 and not the prores.

That is why I asked about the graphics card: may not be able to handle Lumetri on the mp4.

(i see the same on a old mac).

Post screenshot of a clip in Mediainfo and comp specs.

I'm using proxies! does lumetri use the original mp4 instead of the proxy?

 

I tried offlining the file to force it to use proxy. no luck.

but i will try to move the mp4 and see if that helps.
