This software generates a preview sheet by capturing still images from videos. It helps create a contact sheet of all your videos in a simple format.
It's important to note that using -i or -n with values that lead to the same number of vidcaps won't necessarily yield exactly the same vidcaps. This means that users will have to play with these options to find the best results. A helpful example is provided - with a video that lasts for 22 minutes and 14 seconds, -n 6 will create vidcaps at: 3:22, 6:44, 10:04, 13:28, 16:50, and 20:12, while -i 3m will create them at the 3-minute mark and then in increments of 3 up to the end of the video. As such, -n will distribute the vidcaps all over the video, while -i N will start at N and go in increments of N up to the end.
Another useful feature of this software is the ability to set the aspect ratio of the video using -a. This feature is only required for anamorphic material and is discouraged for the rest. Users can set the aspect ratio using either a floating point number (like 1.33 or 1.778) or a fraction (like 4/3 or 16/9). The latter is slightly preferable.
Overall, the Video Contact Sheet *NIX is a handy tool for creating contact sheets from videos and organizing video files. While users may need to play with the -i and -n options to find the best results, the information included on the output image can help users quickly identify important details about their videos.
