Why do I get fluttering videos?

I am getting a slight fluttering in my rendered videos. Here is an example.

This is only a short example, but the play that shows the defensive pass interference has the flutter in it as the pass goes over the head of the intended target.

I have a feeling that it is because of the difference in frame rate that GeForce Experience records the game clip in so I have included those clip properties as well.

Here are the render settings and template settings that I have set and don't know if that is correct to get a clear video without the flutter in the finished render. I have made sure that every clip in the project has resample disabled as well.

Can anyone help with settings that would clear the finished render of this annoying fluttering? It really looks bad in a full video that gets posted to YT.

Best to keep your framerate locked to 60fps when capturing, make sure you don't have variable frame rate recording going on, make sure your project settings match your render settings, and make sure resampling is disabled in project settings.

I haven't figured out how to stop GeForce Experience from recording in variable rate mode, although I have set that to 60fps in the GE recording settings. I posted the question on the Nvidia forum twice and haven't heard back on either post for almost a month now.

I don't see a difference, beside the GE fps issue, in the project settings vs the render settings. As I already noted, resample is disabled on every video clip already.

I should add that there is NO fluttering in the captured recording from GE, regardless of the variable frame rate issue. Is it just that the variable frame rate recordings are an issue?

No, variable frame rate video will not flutter in a player.

Vegas is an encoder, and not a player.

So if I get this, my problem really stems from the source recording that is at variable frame rate, correct? I'll try to correct going forward, but there is nothing I can do differently in my render or project settings for my current video?

We like OBS for screen capture.

I understand. I was just trying to unburden my CPU just a bit, since I know that OBS is more resource hungry than GeForce Experience. Thanks for the settings reference!!!

Actually, it is not the utility that uses resources, but the encoder chosen to do the capture.

I assume that you mean that Geforce uses the hardware encoder to do the capture rather than CPU.

Using the ultra-lossy hardware codec would not be my first choice for screen capture quality.

Both quality and system load were taken into consideration in making the software encoder starting recommendations posted. Good Luck.
