In some cases, users start video editing work from General template, where Filmic view transform is chosen by default. Currently, this causes issue when working with sRGB footage, which are not properly decoded into linear working space and final render looks miscolored. When adding first strip, check it's colorspace and if it corresponds to colorspace for byte images, ensure that view transform is set to default value, which is Standard.
