Previewing Video Filters
The Original window displays what the original file looks like before filtering. The Result window displays the original file with the all the filters displayed in the filter list applied.
The Plus button enlarges both preview images, and the Minus button makes both preview images smaller. If the preview image is larger than the window, scroll bars appear allowing you to navigate through the entire image. You can also click and drag on the image to navigate through the image.
The Fit to Window button resizes the preview images to fit inside the window’s current size. No matter what size the window, this preview mode preserves the aspect ratio assigned to the file. This button is useful if you enlarged or reduced the preview image and want to view the whole image in the window again.
The 1:1 button displays the video at 1-to-1 pixel size. (1 monitor pixel = 1 video pixel)
Use the Scrubber bar to find specific frames in the source video that you want to use so you can see the effect of the filter(s) on the specific frame. You can either click and drag the scrubber or use your keyboard’s arrow keys to step through the video’s individual frames.
Large Preview
Clicking the Large Preview button opens a floating window that allows you to modify the preview size. This is helpful for scrutinizing the finer details of your video. You can use the scrubber bar to find specific points in the video. You can resize the window as needed, and it adjusts the size of the previews proportionally. It also contains the same controls as the Video Filter tab.
