How to Crop a Video?

You crop a video when you want to remove unwanted portions from a clip. For example, if you want to remove a left navigation bar from the recorded clip, you can use the crop feature, to crop out that section.
Note: If you want to remove or block visual from a certain section for just few clips in a video, then we recommend using the blur feature instead, as crop can change the dimensions of the clip, affecting how it sits with the rest of the video.
Navigate to the Crop option in the video editor toolbar
Select the area to keep: Drag your pointer to select the area of the video you want to keep.
Click Crop Video Frame: Click the Crop Video Frame button to crop the selected area
Optional: Enable automatic 16:9 formatting: Check the ratio option for automatic 16:9 formatting. Trainn will automatically crop the clip to fit this format.
Review the cropping effects: When you crop a clip, you keep only the selected part and remove everything else. The borders will change thickness, as cropping affects the clip's dimensions.
Check the resolution: The final size of your cropped video is tied to the resolution of the portion you keep.
Optional: Revert changes: Click the revert button to return to your original settings if needed.
If cropping your video is leading to increased border length, shift the video resolution from 1080p to 720p to maximise clip size. To learn more, refer to this documentation.
