FX3 footage stutters at reduced playback resolution
Footage from the Sony FX3 is having playback issues with Premiere. The odd thing is it plays back normal at full regulation, but if you change playback to 1/2, 1/4, or 1/8 it's super choppy and doesn't play back right.
The footage is recorded in XAVC S-I which is at h2.64 intraframe codec so it should work fine for editing.
The issue is happening in the most recent version of Premiere on both our iMac (intel processer) and our PC workstations. The footage is stored on our shared NAS, with 10gig ethernet.

Hi. This is a known issue that will hopefully be addressed very soon.

H.264 422 MEDIA WILL DROP FRAMES WITH DEFAULT HALF-RESOLUTION PLAYBACK
This is a capture format used with cameras such as the Sony A7siii, and others. This issue typically occurs when playback resolution is set to half.
To avoid this issue, switch to full resolution OR enable High Quality Playback using the wrench menu in the Program Monitor. If you need half-resolution playback only, download the latest Beta versions of Premiere Pro and After Effects, which have the fix for this issue.
We will include this fix in the release versions in the near future. In the interim, consider these workarounds:
- Set playback resolution to full and enable high-quality playback from the program monitor wrench menu.
- If needed, revert to Premiere Pro 15.4.1
- Use the current public Betas of Premiere Pro and After Effects.
