Horizon leveling in Adobe Premiere Pro

Tilted footage is a typical issue when shooting videos: Especially when shooting videos handheld or with badly calibrated gimbals this can occur. Ideally, you are using a tripod with a build in level for your video shoots to ensure your horizon is level. However, even if you have footage with a crooked horizon, Premiere Pro makes it very simple to straighten the horizon.

Below you can find a quick tutorial on how to easily fix a crooked horizon by either using the Adobe Premiere Pro onboard features or a plugin which will make the process even easier.

Using Premiere Pro Onboard Features

1. Adjust the Rotation

You can manually rotate the video in the Effects Control Panel’s Rotation Settings if you don’t want to use plugins. Next, rotate your clip until you are satisfied with the horizon line. When rotating, you can use a grid to ensure that the horizon is always absolutely straight. Plugins such as the Horizon Fixer can automate this task.

2. Zoom in and remove corners

When rotating your footage you’ll find that some black edges appear in the corner of the screen. You will therefore need to modify the scale by going to the scale settings. To avoid cropping in too much you’ll need to find the correct crop level. Zooming in too much might compromise the quality of your video. Especially when adjusting the rotation over time (keyframing) you’ll have to scale in until no corners are visible anymore. When using keyframes you’ll need to repeat the process for all keyframes until every frame does not show black corners anymore. Extensions such as the Horizon Fixer will automate this task and always choose the optimal zoom level.


Using the Horizon Fixer Premiere Pro Extension

The Horizon Fixer plugin comes in very handy when you need a perfectly straight horizon, want to stabilize the horizon if the tilt changes over time, or you have a lot of footage to work with and the previous steps are too time-consuming.

The extension is very similar to Lightroom’s Straighten Tool. It can be used to correct tilted footage by simply drawing a line that follows the horizon. The plug-in automatically adapts the zoom level to prevent black bars and corners. It is also quite easy to stabilize the horizon if the camera tilt changes over time: The keyframe feature can be turned on to correct the horizon. The horizon between keyframes will be automatically interpolated and corrected by the extension.

Horizon Stabilization

You can activate keyframing if the tilt of your footage varies over time. Just straighten out the clip’s horizon at the beginning and let it run for a few frames or seconds. The extension works well together with the Warp Stabilizer effect. It is often helpful to use the Warp Stabilizer effect before utilizing the straighten tool when stabilizing the tilt of your horizon. You can adjust the horizon again if it becomes off, and the extension will automatically correct all frames in between the two keyframes.

Constant Scale

The automatic scaling may cause a sudden shift in zoom levels if the tilt of your video is variable. This might happen when you were filming handheld or from a boat. This plugin has a function called constant scale that takes care of the problem. When this feature is used, the extension automatically detects the highest zoom level required to maintain the horizon of the clip and adjusts the scale to that level.

Stabilizing many Videos

The Horizon Fixer Plugin works well with the Batch Stabilization Analysis Extension. To get extra-smooth videos, stabilizing the footage is advised before horizon correction. However, stabilizing multiple clips at once is difficult. This problem is solved with the Batch Analysis addon, which enables automatic video stabilization within Adobe Premiere Pro. Videos can be background-stabilized before the horizon correction is applied.

The Batch Stabilization Batch Stabilization Analysis Extension is an Adobe Premiere Pro plugin that allows you to queue clips for stabilization. In order to stabilize and analyze clips sequentially and in the background, the plugin employs the Warp Stabilizer effect.
