ReplayMark 2.0 makes detailed video review easier: • Switch between English, Simplified Chinese and German. • Navigate with the scrolling time ruler and a continuous speed slider. • Play or pause directly on the video with a cleaner central control. • Save A–B points for each video and resume at your last review position. • Show marker titles, categories and notes over the video for a chosen duration. • Jump directly to the previous or next marker. • Find an offline operation guide behind the question-mark button. • Updated demonstration screenshots. • A red direction arrow marks backward navigation while preserving video color and brightness.
