Who know about optimisation PP?

We need more details. What type of media (format, frame size, frame rate, codec, etc)? What are your sequence settings? What type of effects are you applying? What other gear is connected to your computer? What types of drives are being used for the media?

To add what Oliver said, also would be helpful to know how much hard drive space is left on your media drive AND your cache drive.

Ok.

Nothing connected with my Mac

I have SSD disk on my iMac

MacOS operating system.

What camera is that media from? That’s a weird frame size. Any idea what the nature of the codec is? MP4 is merely a file wrapper. I presume it’s H.264, but it could be something like H.264 10-bit 4:2:2 (used by Panasonic EVA1 cams), which will choke Premiere.

What are “Handy Seamless Transitions”? I presume some type of third party plug-in.

Is the media playing from your internal SSD? So, cache files, media, and project are all on your internal drive, right? How fast is the internal SSD? And it is an SSD, not a Fusion drive, correct?

[Jason Pray]

So, my camera SONY a6400 4K.

And which is the codec I must use to fast rendering in the timeline?

Handy Seamless Transitions – this is the only transition presets.

How can I know that premiere pro is playing from my SSD?

Yes, all my projects staying on my disks.

The speed:

WRITE: 1728.1 MB/s

READ: 2269.8 MB/s

I don’t have a Fusion drive, i only have 500 GB SSD drive.

Thanks for the details. I would say it’s the codec that your camera generates. I doubt that you will ever get good playback with this codec working natively in Premiere.

If you are finishing out of Premiere, then I would suggest first transcoding the camera media to ProRes (using Media Encoder). Work with that as your “original,” instead of the MP4 files from the camera. Do a small project this way and see if working with transcoded ProRes files improves your performance.

I still don’t understand the 1080×1350 size. That makes no sense. Are you sure that’s correct? Typically if you are editing video for broadcast, YouTube, etc. it would be 1920×1080 (HD) or 3840×2160 (UHD 4K) or maybe 4096×2160 (DCI 4K).

How much empty space is on your SSD? 500GB is relatively small.
