Indeed… it is a way of doing it.
Now, my other problem is to find the best lossless codec that maintain the same source data specifications, like same RGB color space, same bit depth in a way that the result render don’t show gradients in the color space.
Most of them do show gradients (a simple test is to use a sky/horizon scene, like a beach sunset, to spot such gradients, due to loss of color data after render).
Cheers.
