    At the end is also extremely important how the files handle Post work, and nothing less the RAW will do the job well in my experience, additionally not every Raw files handles Post in the same way, were I have found that the RED RAW files do handle extremely well, even under heavy Post work.
    That works... as long as it works. Basically all those motion estimate timewarp tools will compute to a sertain level, it could actually be hairs crossing in the frame and such that just do not do well with such treatment... and there will be shots that works just fine. The thing is that is really hard to judge what will work and what will not. So for that reason I would never promise a client that the it actually will work...

    but I agree when things do not move much in frame and such then it's much nicer to shoot a 5k pass and then use cinespeed or such. But I would allways shoot at the wanted speed / lower res for backup. Just to have when shit fails to compute.

    Cinespeed or Twixtor, but will not be able to do it on Epic MX, only Epic Dragon at 6k, as that is what interests me for my next series of projects.

    Indeed Björn, and that is why I do always also shoot at the highest closest speed possible, and in fact most times while testing we'll do that at various resolution and various speeds, as to give Post the best chance to figure things out, once we know what works and what doesn't, then it can be replicated to those type of shoots, IE, Girl moving her hair fast, Dress, clothes type moving in the wind, cars spinning wheels, galloping Horses and so on.

    But this will be a comprehensive test that we'll do in time in a proper set up as to insure the fidelity of each test, and have data that can reproduce results with good consistency.
