Re: more speed improvements coming
The idea behind monitor scaling was to aid in deep effect stacks, especially when transforming or transparency. Up to this point, the effects were applied to the full resolution video, then scaled down to be displayed in the monitor. As this is very much a single threaded CPU bound feature, it was a great bottleneck for deep effect stacks. I was correcting 4K drone footage for fisheye and color, and adding a title clip on top of that was... well, horrible for performance. The speedup on normal clip playback is a bit unexpected, but might make proxy clips almost obsolete. I have not tested it yet, but that was the general idea. :) Evert Vorster Awesome Chapters Tours http://www.awesomechapters.com Tel: +264 (0) 811477690 On Wed, 15 Jan 2020 at 23:43, farid abdelnour wrote: > > > Em qua., 15 de jan. de 2020 às 16:42, Alistair Riddoch < > alridd...@googlemail.com> escreveu: > > >> I have tested it with a 45 minute project, and there is a >> noticeable performance improvement.

It's not a massive improvement for me, but I'm not using proxy clips yet, so I'm probably not getting the best case improvement. The feature clearly works, as the resolution reduction is obvious in the monitor. No sign of any issues. Thanks for this! Any performance improvement is much appreciated! > > [1] > https://cgit.kde.org/kdenlive.git/commit/?id=31c339ff90d4796b7dfaa36896a21a989d146212 > > [2] https://bugs.kde.org/show_bug.cgi?id=369080 > > -- > .1010.r.i.1101|n.o.i.s.1110|i.m.1010.g.1110|مقاومة > fsf member #5439 > usuario GNU/Linux #471966 > |_|0|_| > |_|_|0| > |0|0|0| > http://www.gunga.com.br;>gunga > http://www.tempoecoarte.com.br;>tempoecoarte > http://www.atelier-labs.org;>atelier-labs > http://www.mocambos.net;>rede mocambos > -- Alistair Riddoch alridd...@googlemail.com http://alistairriddoch.org/

Hi all JB just added a commit[1] allowing monitor scaling. In Monitor menu, you can now select to work in full, 1/2, 1/4 and 1/8 resolution bringing a major performance boost. This adressess Evert's long due feature request. [2] :) This is one of the many improvements MLT will be getting this year. Please test and report issues. (NB, you need latest MLT master.)
