Action! 3.8.0 Stuttering

[not_leffen]

Hi,

Since updating to version 3.8.0, my recordings have been stuttering here and there. I've tried changing all sorts of things in my video recording and editing process and have narrowed it down to the recordings themselves having the stutters. To verify the issue, I reverted to the previous version, re-recorded the same video and the stutters were gone. Exporting the 3.8.0 recording using either version revealed stutters. Exporting the recording that came from the older version (again, exporting it using either version) revealed no stutters. If you need Action! settings, then here they are down below. Specifically, I'm recording Assetto Corsa at 1440p60 and am recording to a 500 GB Samsung 850 Evo:

File Format: AVI
Video Size: Original
Video Framerate: 60 FPS
Video Quality: Ultra
Use Multicore Rendering: Yes

Am I the only one experiencing this? Is this a known issue and a fix is on the way?

Dude I'm having the same exact issue, I'm also recording on a Evo 850 SSD at 1440p60, with your same exact Action! settings, and my videos is having crazy jumps/stutters all over the place. I refuse to record in mp4 since the bitrate is way too low. PLEAE HALP!

I can also confirm that the issue still exists in version 3.9.0, but to a slightly lesser degree.

Please provide me a video sample where your issue occurs?

Please provide me a video sample where your issue occurs?

I already provided one originally when you asked after I started this thread. If you're only looking for big stutters, you won't see them in that one. It's microstutters we're talking about--the kind that are especially annoying because almost nothing is ever done about them. I used that very clip I sent in a video on my YouTube channel, and the stutters are there, even in the local file stored on my PC. I also recorded another one on my channel, but with V3.7, and it did not have the issue as much, if at all.

Here's the video recorded with 3.8.0, including the clip I sent a few months ago. Start at 4:27 and stop when it transitions to on-board views: https://youtu.be/z2DB2f5TX6E
Again, microstutters are what happen here.

Here's another video on my channel, but recorded with 3.7.2: https://youtu.be/Yb8bTcI5n2I
This video has hardly any stuttering, if any at all. This could be luck, though. Regardless, it shouldn't be left to luck regarding microstutters or no microstutters.

Both videos were edited in the same program (DaVinci Resolve 15) and exported using the same settings.
