``--ofopts=""``
Completely empties the options list.
-``--ofps=<float value>``
- Specifies the output format time base (default: 24000). Low values like 25
- limit video fps by dropping frames.
-
-``--oautofps``
- Sets the output format time base to the guessed frame rate of the input
- video (simulates MEncoder behavior, useful for AVI; may cause frame drops).
- Note that not all codecs and not all formats support VFR encoding, and some
- which do have bugs when a target bitrate is specified - use ``--ofps`` or
- ``--oautofps`` to force CFR encoding in these cases.
-
-``--omaxfps=<float value>``
- Specifies the minimum distance of adjacent frames (default: 0, which means
- unset). Content of lower frame rate is not readjusted to this frame rate;
- content of higher frame rate is decimated to this frame rate.
-
-``--oharddup``
- If set, the frame rate given by ``--ofps`` is attained not by skipping time
- codes, but by duplicating frames (constant frame rate mode).
-
-``--oneverdrop``
- If set, frames are never dropped. Instead, time codes of video are
- readjusted to always increase. This may cause AV desync, though; to work
- around this, use a high-fps time base using ``--ofps`` and absolutely
- avoid ``--oautofps``.

``--oac=<codec>``
Specifies the output audio codec. See ``--oac=help`` for a full list of
