Returns the codec of type MovieWriter::Codec . Default is Codec::H264 .

Sets the encoding codec. Default is Codec::H264 .

Returns the output file type. Default is FileType::QUICK_TIME_MOVIE .

Sets the output file type, defined in MovieWriter::FileType . Default is FileType::QUICK_TIME_MOVIE .

Returns the overall quality for encoding in the range of [ 0 , 1.0 ] for the JPEG codec. Defaults to 0.99 . 1.0 corresponds to lossless.

Sets the overall quality for encoding when using the JPEG codec. Must be in a range of [ 0 , 1.0 ]. Defaults to 0.99 . 1.0 corresponds to lossless.

Returns the standard duration of a frame, measured in seconds. Defaults to 1/30 sec, meaning 30 FPS.

Sets the default duration of a frame, measured in seconds. Defaults to 1/30 sec, meaning 30 FPS.

Returns the integer base value for the encoding time scale. Defaults to 600 .

Sets the integer base value for encoding time scale. Defaults to 600 .

Returns the average bits per second for H.264 encoding. Defaults to no limit.

Sets the average bits per second for H.264 encoding. Defaults to no limit.

Resets the average bits per second to no limit.

Returns whether the average bits per second for H.264 have been specified. If false , no limit is imposed.

Returns the four character code for the QuickTime codec. Types can be found in QuickTime's ImageCompression.h.

Sets the four character code for the QuickTime codec. Defaults to PNG ( 'png '). Additional types can be found in QuickTime's ImageCompression.h .

Returns the overall quality for encoding in the range of [ 0 , 1.0 ]. Defaults to 0.99 . 1.0 corresponds to lossless.

Sets the overall quality for encoding. Must be in a range of [ 0 , 1.0 ]. Defaults to 0.99 . 1.0 corresponds to lossless.

Returns the standard duration of a frame measured in seconds.

Sets the default duration of a frame, measured in seconds. Defaults to 1/30 sec, meaning 30 FPS.

Returns the integer base value for the encoding time scale. Defaults to 600 .

Sets the integer base value for encoding time scale. Defaults to 600 .

Returns the gamma value by which image data is encoded.

Sets the gamma value by which image data is encoded. Defaults to 2.5 on MSW and 2.2 on Mac OS X.

Returns if temporal compression (allowing P or B frames) is enabled. Defaults to true .

Enables temporal compression (allowing P or B frames). Defaults to true .

Returns if frame reordering is enabled. Defaults to true . In order to encode B frames, a compressor must reorder frames, which means that the order in which they will be emitted and stored (the decode order) is different from the order in which they were presented to the compressor (the display order).

Enables frame reordering. Defaults to true . In order to encode B frames, a compressor must reorder frames, which means that the order in which they will be emitted and stored (the decode order) is different from the order in which they were presented to the compressor (the display order).

Gets the maximum number of frames between key frames. Default is 0 , which indicates that the compressor should choose where to place all key frames. Compressors are allowed to generate key frames more frequently if this would result in more efficient compression.

Sets the maximum number of frames between key frames. Default is 0 , which indicates that the compressor should choose where to place all key frames. Compressors are allowed to generate key frames more frequently if this would result in more efficient compression.

Returns whether a codec is allowed to change frame times. Defaults to true . Some compressors are able to identify and coalesce runs of identical frames and output single frames with longer duration, or output frames at a different frame rate from the original.

Sets whether a codec is allowed to change frame times. Defaults to true . Some compressors are able to identify and coalesce runs of identical frames and output single frames with longer duration, or output frames at a different frame rate from the original.

Returns whether multiPass encoding is enabled. Defaults to false .

Enables multiPass encoding. Defaults to false . While multiPass encoding can result in significantly smaller movies, it often takes much longer to compress and requires the creation of two temporary files for storing intermediate results.
