Testing methodology

This benchmark compares 2 popular AI short-form video editors, Choppity and Opus.

We tested each tool on the following parameters:

  • Time taken to analyze a video
  • AI reframing
  • AI tracking
  • AI “virality” score
  • Customization and basic editing
  • Smooth video editor playback
  • Time taken to trim a video
  • Time taken to add a video section
  • Languages supported

You can skip to a specific test using the "Contents" window on the left hand side of this page.

We used this 57.5 minute long video for testing. It is a multi-cam podcast recorded in-person - courtesy of the Big Risk Energy podcast hosted by Roei Samuel.

We paid for premium plans for each tool. This ensured that we tested the highest-quality version available for each tool.

Analysis time

We tested how long it took each tool to analyze the 57.5 minute long test video. The less time taken to analyze a video the better, as users will spend less time waiting for the AI. The results and proof of these tests is below.

AI reframing

When turning a landscape video into a portrait one, it is important to crop and reframe it. For example, if there were 2 people side by side in the original landscape video, in order to frame it correctly for a portrait video, the 2 people will often be stacked on top of each other.

Simple input example

In videos with clear distinct speakers on plain backgrounds, all of the tools tested detect faces and reframe in a logical way.

Complex input example

However, in videos with multiple faces in an audience, Opus splits the frame into 4 sections and fails to capture the primary subject.

AI tracking

If a person is giving a talk on stage, or simply moving a lot in their chair, then they may move outside of a static crop. It is important to track the person to ensure that they remain visible in a portrait cropped video. Opus tracks people by making cuts and changing the crop area's position. Choppity tracks people by smoothly moving the crop area.

AI “virality” score

Many tools will assign a virality score to the clips that they select. This score is meant to be a predictor of how likely the video is to go viral.

To test the virality scores of the tools, we uploaded a 2.75 minute long video where the spoken content consists of entirely random words. Note, Choppity does not have a virality score as the company believes that the calculation of such scores are not grounded in true research and science.

Opus created 2 clips with scores of 84/100 and 75/100, stating that “Viral Scores” are “The likelihood that this video will go viral on Shorts/TikTok/Reels”.

Customization and basic editing

Creators and businesses often have a specific brand identity which may include a logo, brand color, brand font.

It is important to ensure that the short-form videos adhere to this brand identity. In addition, users may want to customize videos to improve the production value and to avoid looking like cookie-cutter cloned videos which just have basic captions edited on top.

In the table below, we list the customization features for each tool.

Choppity Opus
Multiple b-roll videos Yes Yes
Multiple image overlays Yes No
AI-generated b-roll videos No Yes
AI-generated b-roll images No Yes
Custom font upload Yes No
Sound effects upload Yes No
Music upload Yes No
B-roll upload Yes No
Text overlays Yes No
Animations Yes No
Zooms Yes No
Sound effects Yes No

Smooth video editor playback

To edit videos, it is important to be able to preview what the final video will look like. It is important that audio and video stay synced and that there is no glitching, stuttering or slowdowns in the video playback otherwise it becomes difficult to know what edits to make and what the final output will look like.

Below, we play a video in Opus’ editor and then in Choppity’s editor back-to-back.

Video trimming

We tested how long it took each tool to trim a video. Trimming a video refers to making the video either shorter or longer.

This is a basic and very common video editing step which users will likely perform multiple times while editing a single video.

Video section adding

We tested how long it took each tool to add a section of a video. This is a common video editing step because often, a user may wish to add another section of the video to add more context or simply to make the video longer.
