Resolution wont drop in programme monitor in Premiere Pro

[JamMasterSam]

So I have a timeline full of 4K footage, when I try to drop my resolution from full to 1/4 the footage in my programme monitor clearly plays back at the same resolution and is giving me massive lag.

I am not a newbie and know there is something weird going on, this has never happened before and now PP is running sooooooo slow.

Hi JamMasterSam!

Thank you for reaching out. I understand that you're having trouble with playback in Premiere Pro. Am I correct?

• Which version of Premiere Pro are you using? https://community.adobe.com/t5/premiere-pro/faq-how-to-find-the-exact-version-of-premiere-pro-you-re...
  
• What are the specifications of your computer [OS/CPU/Memory/GPU]?
• Are you using any third-party plugins? If yes, remove them temporarily.

Please take a look at this page. It shares the best practices for optimizing performance in Premiere Pro: https://helpx.adobe.com/premiere-pro/kb/troubleshoot_playback_performance.html#Solution

Let us know if it helps.

Best,

Hi,

Thanks for the reply. The issue seems to have resolved itself overnight, perhaps an update was installed without my knowing. It was just very odd the resolution wouldn't drop.

I'm using V14.0.0.

I use macOS Mojave v 10.14.6, CPU is 2.8GHz, Memory 16GB, 1TB SSD, GPU Intel Iris Pro 1536MB.

I do use Motion Array extension so will also remove in future if this becomes an issue again.

Thanks

I'm also using Motion Array extension with no such issues encountered

proxy workflow is best practice when it comes to 4k

[JamMasterSam]

Thanks Carlos. I often use Proxies however that wasn't my question, I wanted to know why the resolution wouldn't drop when I selected it to. The issue seems to have been resolved overnight however.

As Carlos said, start using Proxies. They work really well and are fantastic to edit with. Use Cineform or ProRes media for your proxies. The h.264 is what we are trying to get away from for editing.

[JamMasterSam]

Thanks MyerPJ,

Why are editors trying to move away from h.264? I haven't heard this.

[Carlos Ziade]

H.264 requires lot of processing and is not much editing friendly,

more used in delivery to social media since you can have lot

of bitrate manipulation in H.264 (more practical for compression than editing)

[MyerPj]

Yes, again as Carlos said. It's not that we're trying to get away from it. It's just not a good format for editing since it has to be decompressed while playing back. So a bunch of your processor is used just to create the image, whereas when editing with ProRes or Cineform the image is essentially there in the file and ready to play back, so your processor can get on creating a smooth interface for us to work with. Try scrubbing thru a clip in h.264 and then in ProRes and it's an amazing difference.

I also mentioned this as there is a popular proxy tutorials out there where they used h.264. Most of us think Adobe should not have included that as a preset.
