Describe the bug

When adding a drawing on a film, the frame data is inconsitent depending on the frame being drawn in PreviewPlayer mode or Playlist Mode. It shows up at the 'correct' time and @frame links seem to work in both players.

Here's an example:
The first two datas have been drawn in PreviewPlayer mode - the frame numbers are saved as int and are off by one frame. ( First drawing is on Frame 55 on the framecounter ( second screenshot )

The second two datas have been drawn in PlaylistMode - the frame numbers are saved as string and are matching the clock ( third screenshot )

The clocks are the same in PreviewPlayer and PlaylistMode and I think the times might be correct as the drawing is shown on the right frame.

I also found that the PreviewPlayer shows a different image from the video depending on how we seek to it - stepping frame by frame is one frame of from seeking to a specific frame, no matter if we do it with the timeline or through code.
I'll investigate this a bit more and open a second issue for it.
