--- Comment #4 from Andrey <meges...@efenstor.net> --- Another thing: even on my better than average machine 4K editing on CPU-only is painfully slow, so I still at least have to use proxy files. But there is a problem: even such a simple effect as white balance correction causes them to play back slower than realtime or at least on the verge even with the "Track compositing" set to "Preview". I am making art videos which require a lot of fine tuning and inevitably some effects, at least curves and sometimes a vignette, and I don't understand why they are SO slow even when the proxy resolution is quarter the original size? -- You are receiving this mail because: You are watching all bug changes.
