Just a warning for all of you out there. The accept_lowercase option will be removed in the next version. None of you should be using it anyway and I really don't think it has a place in a case sensitive language like python.

Otherwise you might want to use std.FrameEval, std.ModifyFrame or simply Code:
clip.get_frame(n).props['_ChromaLocation'] |

Large page speed hit in ffmpeg
OK this is not a vapoursynth issue but as I read about large pages here maybe some people know.
I few pages back some people mentioned large pages and that it could give some better performance. As I'm doing some 4K material now which is quite slow I thought about trying this out as some people did get some improvement. My systems do have 32GB of memory so that should be fine. But when I enabled large pages in windows and did some tests only using ffmpeg to convert to h264 and h265 (so no vapoursynth yet) I got a pretty big performance hit. Avarage around 20% slower conversions times just in ffmpeg conversions. Did other people run into the same issues? Seen it on intel system with 32GB and an AMD system with 32GB Because if it's like this even if there is an improvement in speed in vapoursynth, if ffmpeg conversion is this much slower there won't be a netto win. Or could I be doing something wrong? |

According to StackOverflow, this is a quite complex topic, much related to the sizes of CPU internal caches (and thus the CPU model), and video encoding may not even deal in general with the kind of RAM access which would benefit from large pages.

R45 is almost done. People just keep reporting small bugs that only take a day to fix so it's dragging a little.
Now for the big question: I've added VSRepo to the installer. Should I offer to install certain scripts or sets of plugins using it from the installer? If so, which ones/which sets?

Hmm maybe some script collections: havsfunc, muvsfunc, mvsfunc , hnwvsfunc + source filters ffms2, d2v, lsmash. This should be enough.

Lsmash has no compiled binaries and thus no package definition. The rest sounds reasonable I guess.
I also plan to allow vs to automatically fetch required plugins using vsrepo but that's a later project.
