In some rare cases Overlay Mixer in combination with YV12 colorspace output causes the video to stutter. Probably due to a bug in the graphics drivers. Solutions: • Change the renderer in Media Player Classic. Start Media Player Classic and click on View in the top menu, then click on Options… (the last item) and then click on Output (under Playback). There you see the output renderer settings under DirectShow Video. • Force RGB32 output in ffdshow. Start the ffdshow Video decoder configuration, click on Output and deselect all colorspaces (YV12, etc.) except RGB32 and enable High quality YV12 to RGB conversion.
