The simplest way is to keyframe the image's Opacity.
Do you understand where to find the Opacity property and how to keyframe animation?
What version of the program are you using and on what operating system?
You could also have multiple instances of it in the timeline with no video in between them on the track above your video. Create a few and copy/paste. Copy/paste the whole thing again, etc.
Yes, I mostly understand keyframing, and I know where the opacity settings are located. Specifically, I have text (a title) that I have in the bottom corner of my video. The video itself is upwards of seven minutes long, using 1080p recording at 29.97 fps. Throughout the entirety of the video, I was hoping to have that text blinking, around one or two times per second. With a video of this length, duplicating the title multiple times, leaving blank space between each instance, and maintaining a consistent time interval between each blink is a little unfeasible.
The title stretches from the beginning to the end of the video on Video 6 (the highest video track in use).
You don't have to create multiple instances of the title if you are keyframing it's opacity.
You just create a set of "blink" keyframes, copy them, then paste them to the keyframe controller timeline as many times as you want your title to blink.
