Tecplot 360 2018 R2.1 introduced the ability to export animations to a series of images. I want to create a movie file from a series of images that I export from Tecplot. < Back Use FFmpeg to create videos from PNGs Export, Image, Tecplot 360 February 27, 2019 txt ', "w") $preview_array = for ($i=0 $i <= 3 $i++) // remove preview list unlink($path_clip. $path_clip = 'path/to/example_preview/ $preview_list = fopen($path_clip. In each iteration, the FFmpeg command seeks to the thumb interval value and creates a 2-second video at a resolution of 320wx180h. We will also store a $preview_array of the clips so we can delete them later. The path to each file will is stored in a list.txt file, which we will need to reference when joining these clips together. To do this we will loop four times and create a 2-second clip at each interval. Now we will create four intervals from where each clip will start from using PHP gmdate() function. Setting the Seconds from the Video to Create Clips from $video_path = 'path/to/example_preview/input.mp4' $dur = shell_exec ( "ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 ' $video_path '" ) $seconds = round ( $dur )
This is done using ffprobe and rounding the output to an integer. The first step is to get the duration of the input video in seconds so we can determine where to get clips from it.
It will be a single low-resolution file containing a sequence of 2-second clips from various parts of the original video.īefore we go any further, here is an example of what the final output will look like: In this tutorial, we will learn how to create a video thumbnail preview from a full video using FFmpeg & PHP.
