You can get the Current frame number when the video is paused as follows:
1. Play the video
fig = implay('Test.avi')
fig = 
    UnifiedScope with properties:
      InstanceNumber: 1
       Specification: [1x1 iptscopes.IMPlayScopeCfg]
          MessageLog: []
          DataSource: [1x1 matlabshared.scopes.source.FileSource]
              Visual: [1x1 iptscopes.VideoVisual]
              Parent: [1x1 Figure]
2. Pause the video.
3. Get the current frame number
CurrentFrameNumber = fig.DataSource.Controls.CurrentFrame
      CurrentFrameNumber =
         953
