I am fairly new to Vegas and am trying to figure out how to "blend" each consecutive frame a little bit to give the illusion of a "smoother" frame rate without actually changing the frame rate. I've done this in the past using specific commands in a particular game's console, but have never done this in Vegas itself. I have seen a lot of posts/videos about how to REMOVE blending that Vegas apparently does innately but it seems I am trying to do the opposite.
While I am recording at 60 fps, I believe sometimes this recording rate drops when there is a lot going on in the game, so even though the end result is a 60 fps media file, it appears lower in areas. Is there a way to take each frame and blend, say 10% or so, of the two surrounding frames? This introduces what some would call a "blur" effect but if it is done subtly enough it will simply make the frame rate look smoother.
May the motion blur is what you are looking for.
Press ctrl-shift-B, and the video bus appears on the bottom of your timeline.
Right click and add envelope "motion blur".
You can keyframe this envelope, so use it only at the portion you need.
You may need the other envelope, "supersampling".
Setting it to a higher amount will produce much finer motion blur.
You can try different motion blur types, set that in project properties.
Be aware, that a long motion blur with supersampling requires a lot of processing power, so the preview may get stuttery.
Hope that helps 😉
