put multiple arrows in one video

inesica
Hello,

I am trying to add arrows on a video on imagej. when i use the arrow tool
plug-in, i can add one arrow on the video, but when i add another one, the
first one dissapears. i tried saving the video with the first arrow, and
then adding the second arrow on the saved video containing the first arrow,
but still, the first arrow dissapears. is there a key i should press (like
ctrl+d for text) that saves the arrow on the video?

Thank you very much for your help and have a nice day!

Cammer, Michael
Perhaps you could flatten the image (Image > Overlay  > Flatten) and save a temp version each time you add a new element.

For each error, press ctrl+b (Image>Overlay>Add Selection). You will need to first uncheck “Set stack positions” in Image>Overlay>Overlay Options if you want the arrows to appear on every video frame. The arrows will be saved with the video when you save in TIFF format. The overlay will be outomatically flattened (Image>Ovelay>Flatten) if you save in AVI (File>Save As>AVI) or GIF (File>Save As>Gif) format.

A while ago I wrote a little macro that allows you to put ROIs including arrows onto a time series and allows you to  set the start and end frame for each of the selections, see Image annotation macro at https://www2.le.ac.uk/colleges/medbiopsych/facilities-and-services/cbs/AIF/software-1/imagej-macros
