How can we improve Premiere Pro?

Better Support For LongGOP

I would love to see better support for H.264 LongGOP. I have a dual XEON rackmount workstation, dedicated NVME cache drive, dedicated NVME RAID array, and NVIDIA 980ti GPU yet Premier Pro still cannot edit 4K @ 30FPS LongGOP H.264 encoded media out of my GH5 and DJI Phantom Pro4 without having to create proxies.

I have followed all of the Premier Pro optimization guides that I can find including dedicated cache drive, disabling adjustment layers until the final render, enabling NVIDIA CUDA acceleration, playback resolution at 1/8, etc. Yet it still stutters badly without proxies on almost all of the footage.

    I have replicated this issue on numerous computers with DJI footage and other Long GOP footage that contains a large number of consecutive P frames. I have done so on unlike systems such as older Xeon, newer Xeon, and new Core processors. The lag observed is an increase in the prefetch latency, that is resolved for a short time by clearing the media cache.

    I hate to be the one to say this but DJI drone footage is buttery-smooth at scrubbing in Premiere Pro 2018 and 2019 CC on my 2014 MacBook Pro (5 year old). On my 2018 Dell with a superior spec, on the other hand, it's hopeless and almost impossible to edit (even on 1/8 resolution).

    I had Adobe support on remote support controlling my PC for 3hrs yesterday and they couldn't solve the problem. In the end they blamed the DJI format.

    On Mac OS, PP v2018 used the CUDA hardware acceleration and v2019 now uses "Metal" [Adobe dropped support for CUDA on Mac]. Both are insanely fast/live compared to the windows version of PP.

    Adobe - please sort this out. You can obviously fix the problem as Mac OS has always been smooth for me, but you haven't fixed it on Windows yet.

    It's sad that I need to rely on a 5year old Mac for 4k editing simply due to Adobe's software limitations.

    Note: Also, PP on my Dell has never resulted in my PC using more than 80% of it's total CPU/RAM/GPU including all running apps, so clearly the hardware is not an issue.
    Also, srubbing through the footage in VLC is buttery-smooth on my Dell.

    +1 for confirming that preview, scrubbing and playback source clips in Premiere Pro CC19 (and also PPCC18) needs some serious improvements for many common codecs.

    I can confirm this behavior, mostly on certain Long-GOP codecs, DJI in particular. AVCHD is bad, too, but that's a lousy codec to begin with, as it's highly compressed, which stresses the CPU on playback. I have iStatMenus installed, where I can see my RAM usage and CPU load at all times, and I'm getting dropped frames & freezes with these certain codecs and very little load on my system's resources (<25%). VLC plays the footage that Premiere doesn't (including AVCHD) beautifully with no frame dropping whatsoever.

    youtuber with 530 subscribers has a video with fifty one thousand views about this issue. that should tell you something that the seven votes here are not telling you (maybe that this issue needs a different title! :))

    And if you play or scroll the same footage at the finder level it’s butter smooth. It needs to be fixed.
