Looking for a tool to create animated diagrams from a PGN file. The usual way that animated diagrams are created is through the animated GIF file which shows separate positions with a fixed time delay between the still frames. The better tools indicate the last move with an arrow (like here for example http://www.apronus.com/chess/diagram/animated/), but what I really need is a video file animation showing the actual continuous motion of the pieces across the board.
There seems to be php code for the apronus example you gave.
This program suggests a way to easily generate GIFs from PGNs.
I dont know any way to do this.
One workaround you can try is:
i) open the PGN in an analyzer. You can also use the chess.com game editor
ii) open a screen recorder
iii) most probably the analyzer shows animations when you click right/left. Record them.
iv) convert the video to a gif.(XD)
This method is not automatic(and is very slow), but it allows you to adjust the time shown per move.
If you could be a bit more specific as to where and how you wish to use it i may be able to give a better solution. The reason I am suggesting this method is that making a gif for a whole game is very impractical.
EDIT: You can use some programming knowledge to make it easier:
1) Open the page with the analyzer
2) Select the right arrow button. Inspect Element. Get its ID.
3) The Inspect editor allows you to change the code (just for yourself). Add a js command to autoclick the button after intervals.
4)Turn on a screen recorder and start recording.
5) Sit back, relax, and do other stuff while the game is being recorded automatically.
WARNING: Do The js thing at your own risk. It may violate some protocols.
