Different Filters Used in Video Editing
Raw video does not always come out as intended. The skillful use of video editing software can produce superb film. Use of transitions and video filters can help aspiring filmmakers produce better looking videos. Here are some of the more popular filter types and how they function. Bear in mind that in editing and making movies, less is more. Using too many effects can damage the look you are going for and the overall quality of the film. Check out different video editing software to see what each product offers as not all effects are available with each program.
Anti-Shaking Filter
Filming without the use of a tripod, monopod or a solid surface such as a table results in shaky footage. This is true regardless of how stable your hands are when holding the device. However, there are some instances when the use of a stabilizing device is not possible. This is where the anti-shaking filter becomes useful. Use of an anti-shake filter can help make your raw footage more stable. Over the years, video editing programs have become better in stabilizing shaky footage. On the other hand, the technology is far from being perfect. If you are dealing with a lot of shaky footage, you may want to invest in a program that has a good anti-shake filter. Test different programs to see which produces the most stable video.
Exposure Filter
Basic camcorders used for holiday trips normally use the device’s automatic settings to shoot footage. For the occasional user, this reduces the need to fumble with the settings yet still end up with decent footage. In some cases, the camera does a good job adjusting these settings. However, if the raw footage still seems a bit off, you can use the video editing software’s exposure filters to spruce it up. The exposure filter includes adjusting the settings for the exposure and white balance. Depending on the software’s features, you can manually adjust these settings or use the auto exposure filter to allow the software to do the adjustments for you. Home users will benefit more from using the auto exposure filter to improve the quality of the footage.
Image Levels Filter
If the auto exposure filter does not do it for you or your video, you may need to adjust the video levels. This includes adjusting the hue, saturation, brightness and color balance among others. Much like the exposure filter, some programs allow users to manually manipulate the settings. Basic programs will allow users to use the auto levels feature instead. More advanced users may need to adjust the settings manually. Adjusting the brightness settings can make the film appear darker or brighter. With the color balance, you can adjust the degree of reds, blues and greens to change the look of the film. The hue and saturation filters function in a similar fashion.
De-noising Filter
One problem with filming in low light conditions is that you end up with noisy footage. You end up with video that has a lot of artifacts. De-noising filters work in three different ways. Spatial de-noising involves reducing the amount of noise per frame. Temporal methods involve decreasing the amount of noise that occurs between the frames. There is also the spatial-temporal method where both techniques are used to reduce the amount of noise in the video.
