BeyondPlayer Pro (originally called Source Player) is a video player for English learners.  It supports almost all common video types and playback functionalities. 

What makes it unique is its dedicated features for English study, such as:

# View definitions easily as you watch videos.

When you watch videos with BeyondPlayer, you can click a word to display its definition in a pop-up overlay. It's far more convenient than searching the definition in a separated dictionary.

# Drag and select to loop lines

With the built-in subtitle panel, you can drag and select lines for repetition. Moreover,  you can repeat the current line by pressing the ENTER key or double-click.

# Save video clip and lines to clip library

You can extra video clip with lines from the current movie to clip library. BeyondPlayer supports both keyword-based and tag-based search in clip library. 
(for the moment, BeyondPlayer only supports extract clips from local file,  extracting clips from YouTube may be added in future)

# Collect word or phrase to word book and word list.

You can collect the words you met in videos for later study. The words in word book can be grouped by word list.

# Automatic word notifications by annotating words

You can annotate a word by extracting the definition from system dictionary or web dictionary.  By doing so, each time you meet the annotated word while watching videos, BeyondPlayer will automatically display a notification to help you recall the meaning of this word.

# View definitions in configurable web dictionaries.

Other than the native macOS dictionary,  BeyondPlayer comes with 7 selected web dictionaries, each one has its own character and benefit. You can even change an existing web dictionary to your favorite one.

# Browse and play YouTube videos.

A Chrome extension is also provided to send YouTube video from Chrome to BeyondPlayer Pro: https://chrome.google.com/webstore/detail/open-in-beyondplayer-pro/cbcaadcmbfdbanoggkblcjjcfkgmigkh

# Download subtitles automatically

BeyondPlayer is integrated with two subtitle search engines, you can search and download the subtitles for the current movie. Modification of search criteria is allowed for better search quality.
