Premiere Pro Playback Stuttering with Vivo X300 Ultra Footage (Mac mini M4) – DaVinci Resolve Works Correctly

Hello Adobe Team,

I would like to report what appears to be a compatibility issue between Adobe Premiere Pro and video files recorded on a Vivo X300 Ultra.

System:

  • Mac mini M4
  • Latest macOS version
  • Latest Premiere Pro version (2026)
  • Vivo X300 Ultra

Issue:
Video playback in Premiere Pro is noticeably stuttery and unsuitable for editing. The same files play perfectly in DaVinci Resolve, QuickTime Player, and other macOS video players.

I have spent considerable time testing different configurations and the issue remains consistent.

What I tested:

  • Standard Video mode
  • Pro Video mode
  • H.264 / AVC
  • H.265 / HEVC
  • Hardware Accelerated Decoding ON
  • Hardware Accelerated Decoding OFF
  • Different recording settings and resolutions

The issue occurs in every tested configuration.

MediaInfo reports the following characteristics for all affected files:

Frame rate mode: Variable
Frame rate: 30.000 FPS
Minimum frame rate: approximately 7.5 FPS
Maximum frame rate: 10000 FPS

Example file characteristics:

  • 4K UHD (3840x2160)
  • 30 FPS
  • BT.709
  • 8-bit
  • AVC or HEVC

Important observation:

The exact same files:

  • play correctly in DaVinci Resolve,
  • play correctly in QuickTime Player,
  • play correctly in other video players,

but stutter significantly in Premiere Pro.

Because the footage works correctly in DaVinci Resolve on the same machine, this suggests the files themselves are valid and the issue may be related to how Premiere Pro interprets or decodes the Variable Frame Rate timestamps generated by the Vivo X300 Ultra.

I can provide:

  • original sample files,
  • complete MediaInfo reports,
  • screen recordings demonstrating the issue.

Please let me know where I can upload sample footage for analysis.

Thank you for your assistance.

      Hi ​@budgettravel,

      Thank you so much for your information and for supplying a test clip I was able to sample.

      Variable Frame Rates with audio attached will default to “Preserve Audio Sync” in Premiere. If you open your Effects Controls Panel with the Source Clip loaded, you can change it to “Smooth Video Motion” there. Be advised, on long clips the audio sync may drift which is a common problem with Variable Frame Rates across all platforms currently.

       

      Effects Controls Panel with Clip loaded in Source Panel

       

      Let me know if this helps or if the problem persists with other clips. It appeared to work for this shorter one on my system.

      Happy to help,

      Amy Stuvland

      Hi. Want to revive this thread since in I'm the similar situation, but worse.

      My X300Ultra footage (shot in Pro Video, Log. H265) is almost unusable. Simply trimming the footage on timeline makes Premiere crashes EVERY. SINGLE. TIME. It takes like 10seconds after I started editing for Premiere to freeze and then I have to force quit.

      Changing the setting as suggested didn't help. The issue is only lessen when I completely remove audio tracks.

      But even then, my exported video has stuttering problem exclusively on X300 Ultra footage.

       

      I know Premiere has issue with VFR video, but I have edited phone footages multiple times with my previous smartphone (Sony Xperia 1VII ; VFR videos as well) and it has zero problem. 

       

      My workaround right now is to transcode all footages with Shutter Converter first. But I'd like this problem to fix as I use my phone for video work.

      For context 

      ASUS Flow Z13 2025, AMD Ryzen AI Max 395+ 64GB (48GB system/ 16GB GPU share)

      Adrenaline 26.6.1. Tested with Premiere 26.2.2 and 26.3. I've tried clearing all caches. 

      I also have PC with Intel 13700K, 64GB RAM and 5070Ti. Will test on it once I received my RAM back from service.

      Hi ​@Paranoing 

       

      Welcome to the Community forums. I don’t know the resolution, bit depth, or chroma subsampling of your footage, but it’s possible you’re converting it from a format not currently supported to one that is. Do you have this same problem transcoding the clips in Media Encoder before bringing them into Premiere or do you have to use the 3rd party software?

       

      Many of these codecs are new, and it can take time for hardware and software to support these natively. I found this article that could help choose a new build in the future, although I would wait until there is an update on it, but I’m glad you found a workaround for now. Adobe is always working on expanding compatibility with new codecs, and phones shooting in VFR are absolutely becoming more common.

      This method works. Thank you. But an update would be useful to eliminate the hassle of having to change this setting every time. In other programs, files play smoothly without any fiddling.

        Hey there,

        Thanks for the idea. You can place any feature request here. I’d be happy to advocate for any change to the current workflow. Thanks for the suggestion.

         

        Thanks,
