When using `hwaccel_args` globally hardware encoding is used for time lapse generation. The encoder determines its own behavior so the resulting file size may be undesirably large.
When using `hwaccel_args`, hardware encoding is used for time lapse generation, using the relevant camera's hwaccel configuration. The encoder determines its own behavior so the resulting file size may be undesirably large.
To reduce the output file size the ffmpeg parameter `-qp n` can be utilized (where `n` stands for the value of the quantisation parameter). The value can be adjusted to get an acceptable tradeoff between quality and file size for the given scenario.
