-Uniform time
-============
 
-Have the default time_base be one that can work with all major time_bases, e.g.:
-  1/24
-  1/25
-  1/30
-  1/60
-  1001/30000 (29.97)
-  1001/24000 (23.98)
-  1001/60000
+Consider making a uniform time class:
 
+```
 class Time():
 
   # Tracks the last value set.
@@ -28,34 +19,4 @@ class Time():
   
   def rebase(self, new_base):
     # Replace the base, and rescale i (if important)

-
-  - Stream.guessed_rate or AVStream.r_frame_rate:
-    FFmpeg's guess as to the frame rate. Often 24/1.
-
-  - Stream.average_rate or AVStream.avg_frame_rate:
-    Average frame rate that has been inspected in the file. This is what VLC
-    reports in the media information. Often near 24/1.
-
-    It may calculate this from 20 frames; see: http://ffmpeg.org/doxygen/trunk/libavformat_2utils_8c_source.html#l02768
-
-  - Stream.time_base or AVStream.time_base:
-    Duration of one time unit for AVStream times.
-
-  - Stream.rate or CodecContext.time_base:
-      The length of a single frame as reported by the file. Sometimes 1/24,
-      sometimes really really wrong.
-
-  possibilities for discrepencies:
-    - .mov supports a fixed frame rate
-    - .mp4 does not support a fixed frame rate?
