Null value for an empty frame

I am using the manual tracking found here: https://imagej.nih.gov/ij/plugins/track/track.html
I have a large video where the tracked object moves in and out of frame occasionally. I want to keep a single track when doing this, is there a way to fill a frame with a null value as opposed to starting a new track?

I have figured it out

@rambunctiouslad Would you be able share your solution here so others who find this thread can benefit? That would be great!

for sure. basically, when using the manual tracking, instead of targeting a pixel (in the frames that don’t have your object), just forward the video as much as you need to, using the arrows at the bottom. that will solve it for you.
