How to Edit Video in After Effects
By landing on this After Effects tutorial page you are probably wondering how video editing works in After Effects, well on this article I'll demonstrate the essential methods to edit a video in after effects such as, cut video clip, trim a video, split video and more…
Honestly video editing with after Effects is not as simple as Adobe Premiere but the good news is that you can pretty much do everything Premiere does the only difference is that it takes little more steps and a little more time, just remember Adobe After Effects was originally built to create visual effects and compositing not video editing 🙂
For those who are video editor, After Effects is not Premiere or Final Cut Pro so please don't waste your time searching for razor cut tool, trimmer tool, split tool… because they do not exist in After Effects yet, that being said all of these can be achieve in AE just check below the multiple methods to edit your videos with After Effects.
And for those who are motion graphic designer you might learn some good video editing tips to use in After Effects to improve your workflow in any case please add you comments at the end if you want to see more and see something missing.
To import a video in After Effects
– Double Click on the project window
– Browse and find your video
– Click Import
– Drag your video on the "create a new Composition" icon
By using this method above it allows your AE composition settings to match your video dimension (width and height), match your video frame rate, and match your video length.
Check the animated demo below
Cut a video in After Effects like the razor tool blade in Premiere is relatively easy follow the instruction below
Start After Effects
On the top tab bar click File > Import > Files… (Shortcut: CTRL+I (PC) | Ctrl/Cmd+Alt+I (Mac) )
Create a composition (shortcut: CTRL+N (PC) | Command + N (Mac))
Drag and drop your video in your composition
Move the "Current time indicator" where you want to cut
Select your video in the Composition
On the top tab bar click Edit > Split Layer(Shortcut: CTRL+SHIFT+D (PC) | Command+Shift+D (MAC))
Now you should see your video cut exactly where your " Current time indicator" was.
In contrary to Premiere, After Effects create multiple layers for each of your video cuts on the timeline.
