In our other outdoor activity article my colleague Oliver explained how to shoot properly with a GoPro and import the footage into our professional video editing software Video Pro X 5. Today I am going to focus on ways to edit imported clips. I’ll look into specifics such as proxy editing, image stabilization, 4K format, and suitable effects.
Effects: I highly recommend using selective color correction and slow motion (especially impressive when combined) for GoPro and outdoor footage. If, on the other hand, you want to customize image effects for a specific purpose, use the “Artistic filter” and “Distortion” options to add some creative flair. For more information on effects check out our series “Introduction to Video Pro X”.
Juddering in Video Pro X 5: As Oliver already mentioned if your video contains quick movements you should use a frame rate of 60, or 120 for slow motion effects. The more frames available to the program, the more smoothly the scene will play.
What happens if you don’t apply these settings? In my example I recorded at 30 frames per second (fps). To solve this issue simply use the “Interpolate intermediate frames” setting. “Interpolate” means that Video Pro X generates/calculates frames in between the original frames. This creates new images whice reduce any juddering that arises when using the slow motion effect. The slow motion effect can be found by going to Effects -> Video effects -> Speed
However, if you do shoot with a high resolution and frame rate many video editing programs will still judder due to the sheer volume of data being processed. As a result the preview monitor won’t play smoothly. Fortunately Video Pro X is different: The new proxy editing feature creates temporarily compressed files which you can use for editing. If the project is exported the original files will be used.
Activating proxy editing: File -> Settings -> Automatically create proxy files
This guarantees smooth editing, even when working with high resolution footage such as 4K, which Video Pro X 5 also supports. The GoPro itself can record in a ultra wide field of view in 2.7K format at 30, 25, 24 fps and in 4K mode at 12, 12.5, and 15 fps. This low frame rate is ideal for making stop motion films.
When you’re playing sports with friends it’s not often that someone with a steady hand is holding the camera, that is if there is someone holding it at all! For decent outdoor footage it can be useful to attach the camera to your helmet. This won’t stop it shaking, however. Video Pro X has an amazing image stabilization tool to correct any shaky footage. Simply right-click on the scene and select the image stabilization option. The window will look like this:
The stabilization radius determines the section where the shaking occurs. This prevents minor shaking or deliberate camera movements from being wrongly corrected. The rule here is: A bigger stabilization radius will correct bigger shakes.
The default area for analysis is the center of the image. If shaking occurs outside of this area use the mouse to move the analysis section. Black borders will appear when you correct shaky footage, they can be removed by simply zooming in. The level you zoom in has a effect on the amount of movement. There is no one-size-fits-all solution, my advice is to increase the size of the default analysis area and test out the other settings.
