Right-click a VideoClip -> Process -> Ping-Pong Video: runs ffmpeg in the
background (forward + reversed video concat, audio played twice), writes
<name>_pingpong.mp4 next to the source and imports it. Supports
multi-select, silent clips (video-only retry), progress display and
unique output paths.
