To use the proxy in a classic way, i.e. as a scaling, select \texttt{Settings $\rightarrow$ Proxy settings} and change the Scale factor from Original size to your downsized choice. You can choose ffmpeg as the File Format \index{file format} and a choice of various codecs associated with that. A good choice is the default of mpeg which can usually be quite fast. In addition, to modify values for that codec, click on the wrench icon.
-We can use the \textit{Proxy 1:1} in two ways: setting "1" as \textit{Scale factor}, or check the \textit{Rescaled to project size (FFMPEG only)} button. In this mode we don't have scaling, i.e. downsize, but only variations of the codec parameters that allow to maintain the original resolution. The advantage is that you can use filters that require the original size to work well. NB: if we set any scaling, by activating the \textit{Rescaled to project size (FFMPEG only)} button we automatically lose scaling and enter Proxy 1:1 mode.

When you have completed your choices, just click OK, and then the video tracks will be rendered. This may take some time, but previous proxy renders will be reused.

-Use the Mixer Viewer to see multiple media playing simultaneously in re-sizable mini-viewers. This can be used in various ways and is useful to edit videos shot by multiple cameras from different viewpoints that were simultaneously recorded in order to create a single good video. Everything will have to be initially synced so you can decide which one of the camera angles is best suited at any time.

Everything will have to be initially synced so you can decide which one of the camera angles is best suited at any time. Mixer mode does not support audio only tracks but there is a workaround described at \nameref{cha:faq_problems_workarounds}.
The number of cameras/mixers you can have is generally limited to the available resources on your computer. Currently, the number of File Descriptors available in the OS limits cameras to about 50. If you have many \textit{mixer viewers} you will probably want to use proxy mode whenever possible. Also, in the \texttt{Settings $\rightarrow$ Playback A} tab \textit{Video Out} section, uncheck \textit{play every frame} and choosing a Video Driver of \textit{X11} with \textit{use direct X11 render if possible} checked, will provide better performance.
