I never start my time keyframes from the beginning because I don't want to start recording from there as shown in the photo, I put them later, and follow all my normal process. The problem is that when I render the video it happens that from the beginning to where I put my first time keyframe, a frozen frame remains until it reaches the point of the first time keyframe, where supposedly It should disappear and only start the video since I put my first time keyframe.
I've tried everything to fix it, but it still doesn't work
