Strange artifacts during camera transition when rendering movie I'm rendering a movie from a series of PNGs with the video sequence editor and the H.264 codec. When the camera changes from the static position to moving there is a strange jitter artifact (see video).

This doesn't show up in the PNGs. Increasing the bitrate doesn't seem to help. I'm not really sure what the other encoding settings do. Is there a way to fix this?
It seems like the motion wasn't estimated correctly. As a workaround you could try to set the GOP Size (Keyframe interval) so that a keyframe is set when the movement starts.

This seems like an encoder/Blender bug. If such errors occurred at multiple times you could encode with a lossless video format and use one of the many third party video converters as a second step. Possibly with multipass encoding enabled.
