Techniques and tools are described for reducing key picture popping effects. In some embodiments, an encoding system filters a video picture that is to be encoded as a key picture using intra-picture compression. The filtering reduces detail in the picture relative to other video pictures that are to be encoded using inter-picture compression. In many cases, the filtering reduces key picture popping effects by selectively attenuating detail in the picture that is to be encoded as a key picture. The encoding tool can use a key picture filter strength parameter to control strength of the filtering. The tool encodes the filtered video picture using intra-picture compression and encodes the other video pictures using inter-picture compression.
