Mouse pointer smoothing lasts a while and then disappears

HI,

 

I am a newbie and working on my first multicam video together with a screencast. The three views were perfectly recorded, although the external GH5 (through CamLink 4K) has some latency issues (shifting the video in relation to the sound restored lip sync). I applied an action when the screen becomes visible in the video to make the mouse pointer more visible and created a call out to zoom in on the foreground window. Still no problems. However, after a while the mouse pointer smoothing (set to maximum) fails and the movement becomes twitchy. What am I doing wrong?

Technical specs set-up:

Mac Studio (2022) M1 Max, 3 monitors: 1x 2560x1440 and 2x 3840x2160

macOS Monterrey 12.5

ScreenFlow Version 10.0.6 (31900), website version

Logitech StreamCam – USB C into port on Mac Studio

Panasonic GH5 – Viltrox 7” HDMI clean feed, HDMI clean feed out into CamLink 4K into USB A port on Mac Studio

Scratch Disk location is Macintosh StartUp volume (SSD device) with 200 Gb space

 

Love to hear from anyone how to fix this. As soon as the issue is resolved I am in on ScreenFlow - a great app!!

 

Regards,

 

Robert

    I may need to see the Action in the timeline and a screen recording or export showing what the Mouse Pointer Smoothing is/isn't doing.

    • CraigS I just watched a tutorial on adding actions. It may just be that the action is not going on for long enough... But how would I show you the action in the timeline?

     That's quite possible. An Action in ScreenFlow is much like start and end keyframes in other editing and motion graphics programs. Want something to go on longer you'd extend the end of the Action.

     It could be a screenshot or even do a screen recording. After all our own ScreenFlow tutorials are recorded with ScreenFlow. ScreenFlow can record itself while you edit.

  • CraigS I tried to extend the action, but I must be doing something wrong as it appears to have no effect. I have added the screenvideo where I show the unstable pointer and moving back showing the stable pointer (closer to the action). What I don't know is how I can inspect the action proprties (so that I could see it only applies for a limited time). That might help also.

      Robert Coelen Thanks for that I can certainly see the issue. Let's investigate some possible causes.
      Let's see if one of the pointer effects are at issue.
      First try disabling Smoothing and see if the shake goes away.
      If that doesn't fix it, disable the click effect (Radar) and Attention effect (Circle) as well.
      I'm thinking it may be a combination that's causing it.

    • CraigS  I'll try it straight away. Turned off the smoothing and the effect was not visible. Let me add foreground window enlargement and see what I get. This did not introduce the erratic behaviour either. Now I'll add smoothing back, but remove the other two effects on the pointer. Adding the smoothing and no other effect will cause the erratic behaviour again. So just the smoothing alone will after about 1 minute start with small shakes and a bit later with the cursor all over the place. If you ask me, from a programming point of view, there is some loop running that keeps adding some movement that gets progressively bigger (that is related to cutting the clip in shorter bits (of about 1 minute). I'll have to forego the smoothing function for the moment, but would appreciate hearing when this is fixed, as it seems a bug to me.

       

      Kindest regards,

  • CraigS I have just attempted a simple version, where I have not done an enlargement of the call-out and just move the mouse over the screen. After a little while, the mouse pointer stability is totally gone. I was able to drag out the action to cover the entire clip, so that is not a problem any more.  Looking carefully, the problem starts about 1 minute into the action. I have added a clip that starts at 46 seconds. I have let it go to (original time frame 2 minutes. I have noticed something else. As soon as I cut the clip (with the action still on it), the pointer starts behaving again (smoothnes) and this lasts for about 1 minute again. SO whilst I could cut a clip abut every minute to make this go away as a temporary measure, I am confident that this is not what is intended for this feature.

       So that would confirm that smoothing is the cause.

       More confirmation.

      I've started investigation FLOW-11555 so developers may look at fixing the issue.

      Can you create and attach a small document just using smoothing that exhibits the issue so the developers can examine directly? That may help them determine other variables.

      Robert Coelen Thanks for that. Can you attach the ScreenFlow document you used to record that? We need to look at how the Action is interacting with the source. Put the document in a folder and zip it and attach it here.

      Robert Coelen Thanks for that. The mouse pointer plays through completely smooth throughout for me. I wonder if having three monitors stresses the GPU's use of the mouse pointer at some point.

      Try disconnecting two of the monitors and reboot.
      Record the same program with similar mouse cursor motion for the same amount of time.
      Then add smoothing and play it back.

    • HI CraigS , turned the two extra monitors off, but it did not settle the cursor squiggle down. After a while (as before) it became extremely erratic. So for the moment I just turn of the smoothing, but of course it would be good to get it back.

      Please include the name of the program you are capturing as you show in your document as that might be part of the issue given we aren't seeing other reports of this yet.

    • Hi CraigS ,

      I did send you the ScreenFlow file a little while ago. I just tested it with that and whilst you apparently did not see the issue, trying it with both extra monitors off did not fix it. BTW, the Mac Studio I am using easily copes with the 3 screens. The program I am recording is MS Word 365

      Robert Coelen Please do try if/when you can. Different programs may have different cursor interactions. We're not seeing other reports of this as of yet.
