Oscar, did you have to align every image, or did you just stack as is? I kept this link to try stacking about 50 images for a very impressionist image. But I have hard time bringing myself to take fifty separate images!

No, I didn't align every image but there is not too much difference between position in shots. I used burst mode and shot 10 pictures with each burst which takes about a second. I moved and rotated slightly during the shots, figuring that a single subject would possibly work best with slight rotation.
Aligning is possible though in the post-stacking process. Doesn't particularly take long, and would be well suited for the pictures as shot in the video. The attached image is a burst of 10 with alignment, which somewhat reveals the actual movement I apparently made.
