Bilkent Video Annotation Tool helps to annotate positions in videos possibly for events later to be processed.

• Developed to be time efficient.
• Supports keyboard shortcuts.
• Saves annotations in JSON format persistently.
• Supports 27 different annotation(event) types at most where each is mapped to an english letter in keyboard.
• Stateful so it continues from the first unannotated video.
• Stores each video's annotation persistently when the video ends or next button is clicked.
• Shows progress at bottom progress bar.

• [Space] Annotate current video with current annotation type.
• [BackSpace] Remove all annotations of current video.
• [Enter] Play/Pause video
• [Left Arrow] Show Previous video
• [Right Arrow] Show Next video (goes to first video at end)
• [Any English Letter A-Z] Sets the current annotation type to the pressed key.
