 === Which encoder should I use? What provides the best quality? ===
 
-It depends. For AAC-LC the likely answer is: `libfdk_aac` > `libfaac` > Native FFmpeg AAC ≥ `libvo_aacenc`.
+For AAC-LC the likely answer is: `libfdk_aac` > `libfaac` > Native FFmpeg AAC ≥ `libvo_aacenc`.
 
 === Should I use AAC-LC or AAC-HE? ===
 
-It also depends. If you require a low audio bitrate, such as ≤ 32kbs/channel, then AAC-HE would be worth considering if your player or device can support AAC-HE decoding. Anything higher may benefit more from AAC-LC due to less processing. If in doubt use AAC-LC. All players supporting AAC-HE also support AAC-LC.

+=== I get an error about "experimental codecs". What does this mean? ===
+
+Some encoders, such as the native FFmpeg AAC encoder (`aac`), are considered experimental and require the addition of `-strict experimental` or `-strict -2` (same thing, different name) to your command as an output option. Otherwise you may see:

+The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
