Preparation Work: Download and install pag into AE.
Open AE, and if you see "File > Export > PAG File..." in the menu, it means the installation is successful.
Software Production
Creating dynamic dticker dffect using After Effects software.
Dynamic sticker effect production specifications:
Production composition size: 720*1280.
Composition frame rate: 24fps.
Duration: Generally around 5s, no longer than 8s, unless in special cases (such as lyrics), pay attention to loop connection at the beginning and end.
Pag Export
After completing the production of the dynamic sticker effect in AE, export the corresponding separate pag package.
First, split all the content that needs to be exported separately, and put them into their own new compositions and name them.
Split content:
Foreground: It does not follow the user's face and is placed at the top to cover the user's view. Common examples include frames, magazine cover layouts, etc.
Facial stickers: Follow the user's face or stick to the user's face. Common examples include blush, nose, head ears, beard, etc.
Cutout background: It does not follow the user's face and is placed at the bottom, covered by the user's view area, providing background content for the user.
Put all the layers or compositions with the same blending mode under the named composition into a new composition, and the duration of the new composition is the loop duration of the dynamic effect.
Select the large composition under all layers or compositions, right-click and choose "Pre-compose".
In general situations, it is suggested to name the new synthesized name as the material abbreviation, such as: hat-mz, and check "Move all attributes to the new synthesized image."
If the new synthesis contains effects that pag does not support, a "_bmp" suffix needs to be added to the new synthesis naming.
To obtain the new synthesis as shown in the following figure.
Ensure large synthesis duration is consistent with new synthesis duration, open synthesis, shortcut key: COM+K, can modify large synthesis duration.
Export the synthesis PAG, click File --- Export --- PAG File.
The Difference between Facial Stickers and Foreground / Background Export
The overall steps are the same as the export steps of the foreground PAG, the only difference is that the facial stickers need to be cut to size first, and then exported in the same way:
Click the "region of interest" tool, draw the area where the hat is located, and drag it to the pointer on the timeline, adjust the smallest area within the safe area, and be careful not to cut to the sticker.
Crop to the appropriate size, Combine > Crop and combine to the target area.
Derive the following size, and export.
If there are different stacking methods, put the layers or compositions under the same stacking mode into a new composition, and export step by step.
Other Considerations
To preview the PAG package, you need to install PAGViewer.
When adding the suffix "_bmp", it is for composite naming, not for layer naming.
