Mike posted a lovely time lapse overt the AAO this morning that had a sequence where each frames was added to the previous one to build up a startrail at the same rate the movie was playing. I thought I'd have a go at writing a PS action/batch to do just that.
Now when I manually do all these steps it works like a dream, but in the batch, it makes no change to the images
. What am I doing wrong?
Here's my procedure:
Before starting the batch I create a new blank image with black background. Select All, copy, and then close this image. There is now a black image in the clipboard. Then I run a batch process on the images that uses the following action:
1. Open the file.
2. Make a new layer.
3. Paste the clipboard image to the new layer.
4. Set the blending mode for the layer to lighten.
5. Flatten the image.
6. Select All.
7. Copy to the clipboard (for pasting into the next image)
8. Save the file.
9. Close the file.
This should leave the first image unchanged, but add all previous startrail images into each frame from there on to build up the startrail, but it's not. It doesn't change the images, and it doesn't close them once they are open.

Does that sound right or am I using the wrong codec?
... it puts some of my clips in the final compilation multiple times in different spots... weird!
