# Encoder settings
|
|
The encoders used can be customized to a high degree. Every encoder besides GIF has some settings.
|
|
|
|
|
|
## Image encoder settings
|
|
The only option here is quality, by default it uses the default for the format you use. You can change it by unticking format default. [More info](http://doc.qt.io/qt-5/qpixmap.html#save)
|

|
|
## Video encoder settings
|
|
The common settings are bitrate and GOP size.
|
|
|
|
GOP Size is the size of a group of pictures.
|
|
Bitrate is the target bitrate.
|
|
|
|
### h264/h265
|
|
The H.26[45] MP4 codec has a few presets to choose. The recommended is to choose the slowest one you can cope with.
|
|
I recommend medium.
|
|
|
|
CRF is the constant rate factor of this video stream, and again I recommend leaving the default value, `23`.
|
|
|
|
### VP9
|
|
VP9 is the WebP codec. Only option it has is lossless encoding, and you want it off, trust me.
|
|
|
|
### GIF
|
|
GIF has no options. It's terrible whatever you do to it.
