i have the same issue.
i am about the finish music video mainly for broadcast. But it will be published web also.
i have HP dream color and set to REC 709. But it seems 709 is darker (especially in lows) than sRGB. For example if i look tha footage in sRGB i can see some details in shadows but in REC709 it is not possible.
if i arrange my footage according to REC709 then i need to “brighten” the lows. But if i arrange to sRGB i can keep it like that but in that case it may be “dark in TV”.
any suggestions?
