UI

• Allow clip end to ignore keyframes. (Ignore step size too?)
• Create popup message for long loading times (getting keyframes, extracting clip)
• Create some notification for clip complete.
• Handle video resizing
• Input box for clip start and end times.
• Timeline zoom for better handling of long vods.
• Move clip start label to left of timeline. Clip end label to right.
• Add tab for console output.
• Replace H:MM:SS.ms time string format with H:MM:SS (n), where n is the frame since last keyframe. Clip start will always have an n of 0, so it can be omitted.

FFMPEG

• Ensure extraction does not lose audio or video streams. Fixed via -map 0 in extract function.
• PREVIEW. Figure out how to play the video segment in the preview panel.
• Currently only supports AV1 mkv video. Now supports whatever the locally installed ffplay can handle.
• Figure out how to print video info to info tab.
• Figure out how to overlay keyboard interface info onto video.
• Diagnose 'TRANSCODED.mp4' appears to have only one keyframe.
• Test seek performance with -ss pre--i vs. post -i. ffmpeg - seeking.

Design

• Job queue.
• Run from file explorer context menu. (Right click file, open with: Clip)
• Create and populate a video info tab. Codecs, duration, resolution and framerate, bitrate, etc.
• Handle case where video file has bad keyframes (e.g. only keyframe at start.)
• Implement logging.
• Handle file overwrite with prompt.

Long-Term

• Implement testing; unit, perf.
• Implement build pipeline.
• Re-implement the range slider to more precisely target our use case.
  • Start adheres to steps, end ignores steps.
  • Implement use of the .bind() method from Tkinter Scale to trigger callback only when slider is released (reduce computational load). StackOverflow.
• Re-implement the preview player without ffmpeg, or integrate ffmpeg window into preview pane.
