Is my IGP my bottleneck? I've tried -all- the common advice

[Peter25587330m3rd]

While starting/stopping playback and attempting to scrub to find specific frames, the Program window just doesn't respond like it should. It hesitates before starting playback, and there are times it just can't handle scrubbing at all. Sometimes, in fact, the video freezes while the audio continues playing.

Here's everything I've done, after spending countless hours researching.

I typically take home movies with my Google Pixel, so I understand I'm already in trouble due to VFR. So I convert the VFR files to CFR ProRes Proxy files using Shutter Encoder. I attach the proxies to my raw files. I create a new sequence

I have the Adobe software on my system SSD, my video files and proxies are on a second, internal storage SSD, and my cache directory is set to a third SSD (external). I delete the cache often (likely unnecessarily).

I've checked boxes to use the GPU wherever I can. I've read, however, that certain processes never use the GPU and only use the IGP.

My PC specs are:
Windows 11 Home
CPU: i9-12900K, 3200 Mhz (overclocked to 5000 Mhz), 16 Core(s), 24 Logical Processors
RAM: 64 GB (32x2) DDR5 6000 RAM
MOBO: MSI PRO Z790-P

IGP: Intel UHD Graphics 770

GPU: NVIDIA GeForce RTX 4060 Ti

It should be flying, I believe.

I've researched Intel Quick Sync, and everything online says "turn it on in your BIOS". Well, there's no setting in my MOBO's BIOS that mentions it. I've researched like crazy "does my MOBO support Intel Quick Sync", and I can find nothing definitive, other than the lack of mention of it it in my MOBO manual or BIOS. My CPU definitely supports it, however again my MOBO BIOS has no setting for it than I can see/unhide.

Could the lack of Intel Quick Sync be my problem?

Afraid I can't help with the QuickSync, not a PC person so hopefully someone else will chime in.

I do think that your source footage is the pain point though. When you have compressed VFR footage like that, the solution is not to use proxies -- it's to transcode to a CFR ProRes file and use THAT as the new master. Proxies are meant for cutting low res before returning to the raw masters clips for finishing; for that type of phone footage there's zero benefit to returning to the raw media. Transcode to ProRes LT or 422 and edit with those instead.

John, the lightbulb has finally lit up. I don't know what I was translating
when I read other posts re: "here's my workflow when I have VFR footage",
but I interpreted all of them as going back to the VFR ultimately.

Thank you for this clarity. I'll see what kind of difference it makes with
Premiere's performance.

Editing with the ProRes files now, and it's a new world. Thank you thank you thank you.

On the iGPU issue - not so much a pain if you are now editing in ProRes but if you ever edit /decode / export H264 or H265 you need your Quicksync iGPU

You have a 12900 'K' suffix CPU you have an iGPU on chip on the processor.

I have an ASUS motherboard using Z690 but I think the BIOS is quite similar usually to MSI.

Its difficult to find it but go into your BIOS and look for an 'Advanced settings' tab. MSI might do same

Then look for System Agent (SA) Config then Graphics Config.

My Primary is set at PCIe (my NVIDIA 4080 Super), then the iGPU Multi Monitor (which drives the on board HDMI on the MOtherboard is set at ENABLED.

To check any iGPU activitiy just go Ctrl Alt Delete in Windows and select Performance - you will see the iGPU and NVidia GPU entries.

Select each one in turn to look at DEcode or Encode activity

Using Pro Res the iGPU won't do much but encoding Pro Res to say another Codec you will see lots of Encode acivity on your NVidia

Ensure the NVidia and iGPU are selected in PremierePro \ Preferences \ Media

As JVK says - ensure all drivers are up to date.

For Intel I use the Intel Driver & Support Assistant which scans your PC to get you the latest drivers

For NVidia download from their site for your 4060. I normally do a Clean Install each time on that one.

You're very welcome! Happy editing.

your igp isn’t the main bottleneck, your rtx 4060 ti should handle playback fine. the issue is more likely adobe not using gpu acceleration fully for scrubbing, so quick sync won’t fix everything.
