Blog: Undoing a Revert Trim Session in Premiere Pro

By Premiere Bro

What is a Trim Session? This blog postulates that Trim Session is a newly enhanced and highly nuanced approach to trim editing in Premiere Pro CC 2015. I’m suggesting three feature requests that will further establish Trim Session editing as an efficient editing workflow in Premiere Pro… I’ve even included a video demonstration of the requests.

When it comes to NLE updates, the hope of every editor is two-fold: improved media management and faster editing. Additional features are just a bonus. So, let’s ignore the Lumetri color panel for a moment and look at an enhancement in Premiere Pro CC 2015 that improves editing. This feature is hidden in the terminology of the Revert Trim Session button.

Revert Trim Session
In a previous post, I hinted that a Revert Trim Session has deeper implications beyond its own functionality. Here’s the Revert Trim Session feature description in the CC 2015 release notes: “A Revert Trim Session button can be added to the Program Monitor to enable an edit point to be returned to its original position before Trim Mode was entered (Premiere Pro Blog).”


But what is a Trim Session? There is no documentation for it, other than it can be reverted. You won’t find either “trim” or “session” anywhere in the Premiere Pro CC 2014 press release. Perhaps it’s an expanded capability of Trim Mode? Then why not call it Reset Trim Mode? No, Trim Session feels more nuanced than just editing in Trim Mode. So what is it besides semantics?

Trim Session Defined
This video defines Trim Session and how it can be improved with three feature requests.

It’s logical to infer that a Trim Session includes all trim activity between the time Trim Mode was entered and exited. In other words, a Trim Session is a series of Trim Mode edits that Premiere Pro treats as one event. Keep in mind, editing in Trim Mode supports continuous loop playback. Now, apply this to editing a radio edit or finessing a rough cut in the timeline. Suddenly, Trim Session begins to look and feel different than other timeline editing methods. Instead of click-and-drag trimming or in-and-out-point editing — both of which require playback to be stopped and manually reset to review changes — Trim Session enables continuous, uninterrupted trim editing, which can be collectively undone in one command. Dynamite.

An Enhanced Trim Editing Workflow
Through the Revert Trim Session feature, Adobe has, knowingly or unknowingly, introduced a new term for an enhanced trim editing workflow. However, it’s as if Trim Session has been teased out without fully delivering on its obvious strengths. Certain functionality is still needed in order to establish Trim Session as its own editing workflow in Premiere Pro. The absence of three features in particular, prevent Trim Session from achieving its full potential.

Trim Session Feature Requests
1. The ability to jump between edit points during loop playback in a Trim Session.
2. The ability to Toggle Trim Type during loop playback in a Trim Session.
3. The ability to toggle target audio/video tracks during loop playback in a Trim Session.

Trim Session editing will truly come into its own when given the capability to switch trim type, jump between edit points and toggle target audio/video tracks without having to stop loop playback. This will enable Premiere Pro editors to work down the timeline, trimming edit points on specific tracks more quickly, and all as one collective event. This ability to continuously adjust and collectively undo without interrupting playback will make Trim Session a very attractive editing method to all Premiere Pro editors.

Note, continuous loop playback is an advantage of Trim Session editing, not a requirement. Loop playback can be paused for fine-tuned edits and still be contained within a Trim Session.

The key message of this post is not about reinventing the wheel or adopting new terminology, but improving Premiere Pro functionality for its users and satisfying the desire for faster editing workflows. Whether or not it’s called “Trim Session” is beside the point. Call it whatever you want; these three feature requests provide the functionality Revert Trim Session inherently suggests, but Premiere Pro does not yet provide. Not to mention, they also give editing in Trim Mode the appeal it never really had.

If you would like to support these three feature requests, simply copy the feature request text above and paste it into Adobe’s Feature Request form.

I realize feature requests are largely opinionated and, if you read this far, I want to thank you for investing your time in something I feel passionate about.

Tutorial: Using Trim editing in Premiere Pro CC 2015

By Sean “Premiere Bro” Schools

Premiere Pro CC 2015 brought more to editors than awesome color grading tools and magical transitions. The new release also brought several enhancements to Premiere Pro’s trimming capabilities.

If you’re a Premiere Pro editor who has never edited in Trim Mode, CC 2015 is the time and version to start. This post highlights three new trim features along with many tips for maximizing the efficiency of Trim Mode editing in Premiere Pro.

1. Trim and Nudge Share Shortcut
Trim and Nudge can use the same keyboard shortcut. Premiere Pro blog: https://blogs.adobe.com/premierepro/2015/06/premiere-pro-cc-2015.html.

Shortcut sharing sounds like chaos: two editing functions — Trim and Nudge — battling it out underneath the keyboard for priority. But it’s not as scary as it sounds. Premiere Pro will perform a Trim when an edited point is selected and will perform a Nudge when a clip is selected. It’s actually profoundly intuitive and it’s a feature that will soon be taken for granted.

By enabling Trim and Nudge to share the same keyboard shortcuts, Premiere Pro consolidates valuable keystrokes by giving them twice the capability. Obviously, only the Trim function of the shared shortcut applies while in Trim Mode. This tutorial shows how to map Trim commands to the default Nudge keyboard shortcuts: https://youtu.be/iEsWIE7hx9I.


2. Revert Trim Session
A Revert Trim Session button can be added to the Program Monitor to enable an edit point to be returned to its original position before Trim Mode was entered — Premiere Pro blog https://blogs.adobe.com/premierepro/2015/06/premiere-pro-cc-2015.html (Note: Revert Trim Session is also a keyboard shortcut.)

Simply put, Revert Trim Session undoes successive trim edits made in Trim Mode. The ability to return an edit point to its original place, prior to changes, with one click, will make Trim Mode more appealing to many Premiere Pro editors. The Revert Trim Session feature is also particularly intriguing because it introduces a new trimming terminology: “Trim Session.” Although it’s logical to assume that Trim Session refers to all trim activity within Trim Mode, there’s no official documentation for this functionality. It may be reading too much between the lines, but it’s as if Adobe is using this language to suggest an enhanced trim editing workflow. More on that in a future post.

3. Loop Playback ‘Live Trimming’
In loop playback Trim mode in the program monitor, the I and O buttons can be used to adjust the position of the edit point on the fly — Premiere Pro blog: https://blogs.adobe.com/premierepro/2015/06/premiere-pro-cc-2015.html.

We’ll coin this feature “Live Trimming” until a more official term is given by Adobe. It’s similar to “J-K-L Dynamic Trimming” (which still works in CC 2015) but it’s uniquely different in that making an edit does not require playback to stop.

While playback is looping in Trim Mode, pressing “I” and “O” will set a new in and out point (based on the current trim type) for the outgoing or incoming clips. When an edit is made, loop playback will reset on the new edit point and further editing can continue.

In a way, Live Trimming feels similar to multicam switching in being able to watch playback and make an edit when it feels right. This new functionality within Trim Mode gives Premiere Pro editors a more dynamic and interactive trim editing experience.

Key Point Recap
The following tips will increase the speed and efficiency of trim editing in Premiere Pro CC 2015:
• Assign keyboard shortcuts to each of the “Select Nearest Edit Point…” commands. This will allow you to jump to the nearest edit point with a specific trim type, instead of having to select the edit point and then Toggle Trim Type (Ctrl+T).

• In Trim Mode, select your trim type before you begin loop playback. Playback must be stopped to change trim type.
• Try first using “I” and “O” Live Trimming to trim the edit point to where it feels right. Then, continue to finesse using the Trim keyboard shortcuts.
• Cmd+Z will undo the last trim edit without exiting trim mode or interrupting loop playback.
• Assign keyboard shortcuts to each of the “Toggle Target Video…” commands. This will allow you to make trim edits to clips on specific video tracks. Do the same for all the “Toggle Target Audio” commands.
