(Alternatively you might also give Lagarith a try, which should compress a bit better and supports multi-threading)

Huffyuv is often pretty slow because it doesn't have interframe compression or multithreading.
I was mainly just looking to check the framerate, whether x264 was compiled with asm, and so forth (the stuff before all the warnings). |

@DarkShakiri,
I use FastStone Capture which unfortunately outputs WMV videos. Yet I could never convert the WMV into h264 (Using x264) with similar quality at the same size. Could it be WMV has a feature which makes it optimized to Scree Capture? |

Could you please give me recommended parameters inside VLC convert screen? Is there any open standard video compression with similar results to WMV for this type of content? It has amazing results with very low bit rate. |
