The format rgb in ffmpeg uses more cpu time. When the file loads, however, it will initially take longer because it is running through the video filter. Video_filter=xxxxxx=threads=8 # where xxxxxx is the desired filter If you load a file in C INELERRA-GG with aįile containing the following line, the full scale color modeling upgrade will not be performed until after any plugin, and then the render is faster: If using an ffmpeg plugin that uses filters and many passes over the data, the amount of data is a big factor.

But when cinelerra loads a video it uses full scale color models. Direct usage of a particular ffmpeg plugin from the ffmpeg command line might handle the planar at less than full scale chroma (yuv420), which means there is less data to manipulate. All of them have 3 components at full scale. For a specific color-based example, C INELERRA-GG uses 6 primary rendering color models. You can speed up some ffmpeg plugins that are quite time-consuming and use a lot of CPU.
