Hi, i have a big problem, when i'm doing speed ramping, (200% or 300%), the use of my ram goes from 8go to 31.9 then my SSD (C) goes from 0% to 100% and my pc remains frozen for 5/10 minutes, until I can close premiere pro with task managers. if anyone have suggestion it will help me a lot

 

my pc spec :

MSI X570 GAMING PLUS, R7 3700X, 32go 3600hz, RTX 2070 super, 1 NVME and 2 SSD

mp4s are a type of mpeg compressed video.    Every frame is not complete... usually the first and 15th and 30th (and so forth) are complete and the frames in between are just the differences between the previous and subsequent frames...  So playing them requires great processing power and when you're attempting to do a gradual speed change, you're asking a lot of your computer.  You can use Premiere or Adobe Media encoder to transcode to a format like one of the prores variants in which each frame is complete.  These files will be much larger but will make lower demands on your system.  Worth a shot converting one file to prores 422 with matching pixel dimensions and frame rate and see if you still experience this issue...

      When you say speed ramping, are you talking about keyframed gradual change of playback speed?  what are the properties of your source clips, in particular the codec (also known as the compressor).   I'd suggest transcoding to an all i-frame format like prores where each frame is discreet rather than an mpeg format like h264...  Also, you might try switching your renderer (in project settings: general) to software?  Happy to go into more detail about why I'm thinking this might be the source of the problem, if you don't understand...  Not always easy to get a handle on your premiere and video chops from a post...

        sorry for the late answer, for speed ramping you can look at the (screen 1) , the clip is in 2560x1440 take with OBS (screen 2), i have edit a lot of thing but it's the second time i can't edit because of that. 

        How i can transcode ? (like that ? image 3). I'm already on the Cuda renderer i think it's the best no ?

         

        I finally managed to do my editing by making proxies, but I would still like to understand that makes me, why the ram & SSD and not the processor or GPU
