+ * Tidy up filters dialog by not showing those
+ that are not configured in FFmpeg, and by splitting
+ them up into categories.
+
+ * Fix infinite loop of error messages when
+ `playing back' using a non-existant filter (#39).
+
+ * Encode data straight to MXFs, rather
+ than going via .j2c files. Should roughly
+ halve required disk space and reduce time
+ taken.
