Understanding 1s and 2s in Stop-Motion Animation | Dragonframe Tips and Tricks

[Magshifter]

​

In stop-motion animation, the terms "1s" and "2s" refer to the animation's frame rate and smoothness.​

1s (One Frame per Exposure)​

This means that each frame of animation is shot once. With the standard frame rate for film and television being 24 frames per second (fps), this would mean that each of the 24 frames per second is a unique shot. Animation on 1s looks very smooth and detailed, but it requires more time and effort to create because you need to make 24 unique frames for every second of animation.

2s (Two Frames per Exposure)​

This means that each frame of animation is shot twice. Therefore, at a frame rate of 24 fps, you are actually shooting 12 unique frames, each shown twice to fill the 24 frames per second. Animation on 2s looks less smooth than on 1s, but it requires less time and effort to create, as the number of unique frames you need to create is halved.

Example​

• On 1s: Frame 1, Frame 2, Frame 3, ... Frame 24.
• On 2s: Frame 1, Frame 1, Frame 2, Frame 2, Frame 3, Frame 3, ... Frame 12, Frame 12.

Using 1s or 2s depends on the project's requirements and the available production time. Often, both approaches are combined in animation; for example, character movements might be animated on 1s for smoothness, while less significant parts of the scene are animated on 2s to save time.

How to Set This Up in Dragonframe​

Dragonframe, the popular stop-motion animation software, provides tools to facilitate shooting in both 1s and 2s modes. Here’s how you can do it in the program:

Setting Hold Frames​

In Dragonframe, you can set the number of repetitions for each frame in the "Timeline" panel.

1. Select the frame you want to repeat.
2. Set the "Hold Frames" parameter to 2 for 2s, or leave it at 1 for 1s.

Configuring Automatic Exposure​

1. Go to the "Scene" menu and select "Scene Settings."
2. Navigate to the "Exposure" section and specify the exposures per frame. Set it to 2 for 2s mode.

Using the Step Option in Capture​

1. You can set the shooting step (Step) to 2 frames in the Capture interface. This means each shot will be shown twice in the sequence.

By understanding and utilizing these settings, animators can achieve smoothness and detail in their stop-motion projects while optimizing their workflow.

Example Scene Combining 1s and 2s​

Imagine a scene where a character is walking down the street, then suddenly turns and starts running. In this scenario, you can combine 1s and 2s animation to achieve the optimal balance of smoothness and efficiency.

Scene Breakdown:​

1. Character Walking:
   • On 2s: For the character's walking motion, you can animate on 2s because walking is a slower, repetitive movement.
   • Animation on 2s: Frame 1, Frame 1, Frame 2, Frame 2, Frame 3, Frame 3, ...
2. Sudden Turn:
   • On 1s: When the character suddenly turns, this quick and significant movement can be animated on 1s to provide more smoothness and expressiveness.
   • Animation on 1s: Frame 4, Frame 5, Frame 6, ...
3. Starting to Run:
   • On 1s and 2s: The first few running steps can be animated on 1s for smoothness, then transition to 2s to save time and effort.
   • Animation on 1s: Frame 7, Frame 8, Frame 9, ...
   • Transition to 2s: Frame 10, Frame 10, Frame 11, Frame 11, ...

How to Do This in Dragonframe​

1. Character Walking (2s):
   • In the "Timeline" panel, select the walking frames.
   • Set the "Hold Frames" parameter to 2 for each walking frame.
2. Sudden Turn (1s):
   • Select the turning frames.
   • Set the "Hold Frames" parameter to 1 for each turning frame.
3. Starting to Run (1s and 2s):
   • Animate the first few running steps on 1s by setting "Hold Frames" to 1.
   • Switch to 2s for subsequent steps by setting "Hold Frames" to 2.

Using this technique, you can create scenes with optimal smoothness and efficiency, combining 1s and 2s animation depending on the movement and importance of the scene.
