Good news, the problem Warp Stabilizer is fixed in the latest release 12.1.2.

Thank you!

Hi,

The playback is done on AJA devices (Io 4K or T-Tap) in 1080i29.97 on HDTV monitors. It’s hard to notice on computer screens since it’s progressive and not interlaced.

Right now, the workaround workflow I use is:
– pack all the shots to stabilize in a single timeline
– export to XML
– open in CC 2015
– stabilize the shots
– copy/paste stabilized shots in CC 2018
– tweak stabilizer settings and render in CC 2018

Playback is smooth in CC 2018 until the clip length doesn’t change.
If it does and I re-analyze the clip again in CC 2018, playback is no longer smooth. I have to redo the workaround process.

Thank you.

What you see in the comparision are not just previews, but are the final 1080i60 exports.
The first field seems good, the second field looks like it’s that of the frames after, which makes the playback jerky.

What you see in the comparison image are no previews, they are the final 1080i60 exports.

I did a test with the same shot and the same sequence settings in PPro CC 2015, then in PPro CC 2018 and the playback was way smoother in CC 2015. Also, I took the test shot, applied the WS in CC 2015, then converted the project to CC 2018, then the playback was smooth! If I re-analyze the clip, then it’s no longer the case. So I suspect the analyze proccess fail with interlaced footage in PPro CC 2018 only.

For a final test, I also took the same test shot in After Effects 2018, applied WS VFX, rendered it with upper fields, it plays smooth too.

Take a look at the still frame comparison I made to see the fields difference.
