preview and timeline speed up after I click play

I attached a video where it displays the issue but basically steps to reproduce for me are:

1. select a random position in timeline

2. hit play

3. preview speeds up for few seconds

4. back to normal

 

this issue is worse when adding effects or transitions, what I've tried:

1. reinstalling premiere

2. reinstalling and updating nvidia drivers

3. updating windows

4. checking the bios and the PC for any issues on performance

5. various settings found on internet or forums to help with the issue (none of that worked)

6. tried different clips

7. disabled internal gpu

8. jkl does not work, it's not clip related

 

I have Acer Nitro 16 with rtx 4070 gpu 32gb ram and ryzen 7 7840hs, I don't know anymore what to do, any other video editor works flawlessly

    Thanks for sharing the screen recording. Have you already tried configured "Audio Hardware"? Edit > Preferences >Audio Hardware > "Default Input" to "No Input". What's the source of the media files? It looks like variable frames. Can you try checking the frame rate of the media files? Using Mediainfo (a free and open-source program that displays technical information about media files)

    You may open the file in MediaInfo, click View and then select Tree. Under the Video dropdown, if the Frame Rate Mode is listed as Variable, then it is a VFR media. If they show variable frame rate, In such cases, it is recommended to transcode these media files to Constant Frame Rate and then use them in Premiere Pro. These particular files may need to be transcoded in an "open source" application like Shutter Encoder. Handbrake

     

    Let us know how it goes.

    It looks like its always trying to keep up. You're pressing play to start it, and then it skips about. It's not uncommon.

     

    For a test, Use Shutter Encoder to transcode one of the AVC files . Maybe try ProRes LT or even ProRes PROXY format within Shutter Encoder for easy to edit formats. Give that file a try in PP and see how it goes.

    I don't understand the 'speeds up', as in going faster than it should? It looks like it just starts playing, and needs a few seconds to catch it's breath? Your hardware (a laptop) may be meeting it's match.

    it starts playing but it is like 2x or something, the laptop is very good in specs and another laptop that I have doesn't have this issue at all, and it's way older so I'm sure it's not a machine issue, well not performance at least, I'm trying to understand if there is an issue between internal graphics which is amd 780m and discrete Rtx 4070 since on this machine they work together, but didn't come to a solution so far

      Thank you for the quick response but neither of those helped me with the issue, the files I'm using are usually 1080p to 4k at constant frame rate
