Just use SubtitleEdit. It's free and powerful. One of the best I've used for subtitling. That waveform editor is perfect to check timings. Stop wasting your time doing subs where they aren't supposed to be made. And with a paid plugin, no less.

I agree. works better than I expected..

What Nathan said. You have to choose the output display transform (ODT) from the monitor you're using. To try and make it simple, if you're using an alexa and seeing it on a flatscreen tv your IDT is the alexa and your ODT is rec.709 which is the standard color profile for tv's. If you're releasing your movie in the cinemas your IDT is the same (alexa) and your ODT has to be DCP (digital cinema package). You just have to change your ODT to each delivery method you'll use since all the math will be done by that. You make the grade between those 2 processes.
Yes, we do have LUTs that can kinda do that now (check impulZ luts by visioncolor, they do separate the process into a negative and print stage to resemble the color negative process in the film days) but the real power of ACES is that you can color balance different cameras more easily since the IDT part has been thoroughly calculated by the Academy (with support from the camera manufacturers) and is much more accurate than some LUTs we may use now (and will keep improving with research). Hope this helped a little bit. It's been almost a year since I did research on ACES so some things might not be explained as well as I hoped...

Beautiful imagery. It's like he said, when watching, say, a movie. You won't even notice it's either the Helium or the Weapon. It's just the incredible flexibility and reliability that it gives you and when comparing the 2 side by side that you know the power of the Helium.

Insightful post. #10 is interesting and I will certainly keep that in mind when I go on a festival run.

Incredible article and inspiring story.
Congratulations NFS and thank you for writing this article.
