Frame-by-frame animation or CEL Animation is one of the earliest animation techniques. It involves drawing thousands of individual frames or pictures and mixing them together to create motion.
Frame-animated visuals are very complicated and time-consuming. Every single second of them involves 24 to 30 frames, so normally, multiple artists work in the same video. However, here, every frame precisely captures the emotions, background, and movement of the one preceding it. Thus, CEL Animation videos are very smooth and pleasing to the eyes and the mind.
A frame-by-frame animation video needs a lot of money and even more skills and dedication. Only a few artists even have the patience to make them these days. There’s a lot to lose if not done in the right way- you must be very sure that the company you hire will deliver.
