Compositions and footage items are listed in the Project panel. Unlike items in the Timeline panel and Effect Controls panel, the order of items in the Project panel has no influence on the appearance of the movies that you create. You can organize footage items and compositions however you like, including organizing them using folders. Solid-color footage items are automatically placed in the Solids folder.
Folders that you create in the Project panel exist only in the Project panel. You can expand a folder to reveal its contents, and put folders inside other folders. To move a file or folder to the top level of the Project panel, drag it to the gray information area at the top of the panel.
You can use the search field in the Project panel to find footage items that meet various criteria, such as those with missing source files. See Search and filter in the Timeline, Project, and Effects & Presets panels.
For a helpful video tutorial about organizing assets in the Project panel, see this video tutorial by Jeff Sengstack and Infinite Skills.
You can use the Set In Point , Set Out Point , Ripple Insert Edit , and Overlay Edit controls in the Footage panel to trim a footage item and insert it into a composition. Trimming in the Footage panel can be more convenient than adding the footage item to a composition and then trimming its layer in the Timeline panel.
Jeff Almasol provides a script on his redefinery website that automatically writes specified information about footage items or layers to the Comment fields for the respective items in the Project panel or Timeline panel.
Christopher Green provides a script (Project_Items_Renamer.jsx) on his website with which you can rename compositions and footage items selected in the Project panel. You can search and replace text in the names, append characters to the beginning or end of the names, or trim a specified number of characters from the beginning or end of the names.
Lloyd Alvarez provides a script on the After Effects Scripts website with which you can search an After Effects project and replace the file paths for the sources of footage items. This is convenient for swapping out source files, updating a project after moving sources, or updating a project after moving it to a different computer system.
Select the item in the Project panel, press Enter (Windows) or Return (Mac OS), and enter the new name.
Right-click (Windows) or Control-click (Mac OS) the item, choose Rename, and enter the new name.
You can use the Comment column to create a custom sorting option. Rename the column, enter corresponding information for each item (for example, camera number), and then sort by that column.
When items are previewed in the Footage panel, they show the results of the footage interpretation operations. (See Interpret footage items.)
To open the source for a footage item using the player application associated with that file type, Alt-double-click (Windows) or Option-double-click (Mac OS) the footage item in the Project panel. See the documentation for your operating system for instructions for changing the associations between applications and file types.
You can organize your solids, adjustments layers, and nulls better with enhanced solids folder organization. You can perform the following tasks:
Select the folder and press Enter (Win) or Return (Mac).
Type a new name in the name field.
Right-click and choose Rename. For example, rename the folder to Color Squares.
After renaming the folder, a warning message is displayed when you try to create a solid.
Click Yes, and use “Color Squares” to continue using the renamed folder.
If you want to create the solid in a new solids folder, click No, use “Solids”.
To open Preferences window, select Preferences > New Project.
In the Preferences window, enter the new name in New Projects Solids Folder text box and click OK.
These settings are applied to the new folders you create. Your current projects are not affected.
You can not nest folders in Team Porjects.
Right-click the preferred folder in the Project panel.
Choose solids folder from the menu to set it as the solids folder.
You can only set one folder at a time as the solids folder.
For more information, see solids color layers and solids color footage items.
You can open and edit a footage item in the application in which it was created, directly from an After Effects project. The original application must be installed on the computer that you are using, which must have enough available RAM for it to run. When you edit and save changes to the footage in the original application, the changes are applied to all instances of the footage when After Effects becomes the active application.
If you’re editing footage that has an alpha channel, make sure that you’re viewing and editing all of the channels, including the alpha channel, in the other application. Otherwise, changes you make may not be applied to the alpha channel, and it may become misaligned with the color channels.
When you edit a still-image sequence selected in the Timeline or Composition panel, the individual image that is currently displayed opens. When you edit a still-image sequence selected in the Project panel, the first image in the sequence opens.
Before reducing your project, removing unused footage, or consolidating footage, consider making a backup by incrementing and saving your project first. (See Save and back up projects in After Effects.)
Carl Larsen demonstrates the use of the Collect Files command and the Consolidate All Footage command in a video tutorial on the Creative COW website that shows how to organize, consolidate, and archive project files and footage.
When a duplicate item is removed, layers that refer to the duplicate item are updated to refer to the remaining copy.
This command removes both unused footage items and all other compositions that are not included within a selected composition as nested (subordinate) compositions.
If the selected composition includes items that are turned off (that is, the Video or Audio switch is deselected in the Timeline panel), the Reduce Project command does not remove those items.
If an expression in a selected composition refers to an element in a nonsubordinate composition, Reduce Project removes the nonsubordinate composition and the applied expression. A message appears after you choose Reduce Project to remind you of this possibility, so you can undo the command if needed. To avoid removing the expressions from a nonsubordinate composition, drag the nonsubordinate composition into the composition that refers to it. Then deselect the Audio and Video switches for the composition that you added.
The SaveCompAsProject script from Sebastian Perier on the AEScripts website saves selected compositions as individual projects.
When you want to temporarily use a substitute for a footage item, use either a placeholder or a proxy.
A still image of color bars used to temporarily take the place of a missing footage item. Use a placeholder when you are building a composition and want to try out ideas for a footage item that is not yet available. After Effects generates placeholders automatically, so you do not have to provide a placeholder footage item.
Any file used to temporarily replace a footage item, but most often a lower-resolution or still version of an existing footage item used to replace the original. Often, storyboard images are used as proxies. You can use a proxy either before you have the final footage or when you have the actual footage item but you want to speed up previewing or rendering of test movies. You must have a file available to use as a proxy.
Any masks, attributes, expressions, effects, and keyframes that you apply to the layer are retained when you replace its placeholder or proxy with the final footage item.
In the Project panel, After Effects marks the footage name to indicate whether the actual footage item or its proxy is currently in use:
A filled box indicates that a proxy item is currently in use throughout the project. The name of the proxy appears in bold type at the top of the Project panel when the footage item is selected.
An empty box indicates that the footage item is in use throughout the project, though a proxy has been assigned.
No box indicates that no proxy is assigned to the footage item.
For best results, set the placeholder to the same size, duration, and frame rate as the actual footage.
If After Effects cannot find source footage when you open a project, the footage item appears in the Project panel labeled Missing, and the name of the missing footage appears in italics. Any composition using that item replaces it with a placeholder. You can still work with the missing item in the project, and any effects you applied to the original footage remain intact. When you replace the placeholder with the source footage, After Effects places the footage in its correct location in all the compositions that use it.
You can find footage items for which the source items are missing by typing missing in the search field in the Project panel. See Search and filter in the Timeline, Project, and Effects & Presets panels.
When you use a proxy, After Effects replaces the actual footage with the proxy in all compositions that use the actual footage item. When you finish working, you can switch back to the actual footage item in the project list. After Effects then replaces the proxy with the actual footage item in any composition.
When you render your composition as a movie, you may choose to use either all the actual high-resolution footage items or their proxies. You may want to use the proxies for a rendered movie if, for example, you simply want to test motion using a rough movie that renders quickly.
For best results, set a proxy so that it has the same frame aspect ratio as the actual footage item. For example, if the actual footage item is a 640x480-pixel movie, create and use a 160x120-pixel proxy. When a proxy item is imported, After Effects scales the item to the same size and duration as the actual footage. If you create a proxy with a frame aspect ratio that is different from the frame aspect ratio of the actual footage item, scaling takes longer.
To locate and use a proxy, select a footage item, choose File > Set Proxy > File, locate, and select the file you want to use as a proxy, and click Open.
To toggle between using the original footage and its proxy, click the proxy indicator to the left of the footage name.
To stop using a proxy, select the original footage item, and choose File > Set Proxy > None.
Use the Create Proxy command to create a proxy from footage or compositions selected in the Project panel or the Timeline panel. This command adds the selected footage to the Render Queue panel and sets the Post-Render Action option to Set Proxy.
File > Create Proxy > Still to create a still image proxy.
File > Create Proxy > Movie to create a moving image proxy.
You can create placeholder files that can be used in different compositions. For example, you can create a placeholder for an item in the render queue that will create a 24-fps movie and then drag that placeholder into a 30-fps composition. Then, when you render the 30-fps composition, After Effects first renders the placeholder at 24 fps and uses this rendered version as it renders the 30-fps composition.
If you intend to loop a visual footage item continuously in your project, you only need to create one cycle of the footage item in After Effects.
Lloyd Alvarez provides a script on the After Effects Scripts website that automatically loops a footage item, composition, or layer.
You can now freeze the last frame of a layer until the end of the composition. After Effects sets time remapping keyframes in the layer and extends the layer duration until the end of the composition.
To freeze the composition on the last frame of your footage, choose Layer > Time > Freeze on Last Frame.
