Tutorial video - Sony explains S-Log3 and Cine EI on the FX30

[10:16 Wed,12.October 2022 by Rudi Schmidts]

Sony&s S-Log3 gamma curve, Cine EI and colour grading obviously remain a hard-to-open book with seven seals for many users. So difficult, in fact, that Sony itself has now tried to explain the terms in a production context. And of course, in keeping with the times, not as a text, but as a YouTube tutorial video.

Whether or not this is ultimately successful will still depend heavily on the user&s level of knowledge. Especially since the workflow is not explained in Resolve but in Sony&s Catalyst, which is usually too small for typical grading tasks.

Sony proceeds in two steps. The first part deals with the advantages of log recording over standard profiles. And in the second part you learn about the interaction of base ISO and a playback ISO from the metadata. In other words, exactly what Cine EI is all about.

If you are curious or just want to get an impression, you can have a look at the video right here.

Personally, we think it&s a good idea for manufacturers to use videos to make it easier for their users to understand complex issues. At the same time, however, important aspects are almost always overlooked.

For example, this video explains Cine EI in direct interaction with ETTR (without mentioning this by name), which certainly not every DOP would leave as an explanation. The automatic Cine EI setting of the FX30, which partly corresponds to an uncontrolled AutoISO setting, is also presented uncritically as a professional tool, which in our opinion deserves a few more words of consideration.

But since we know from our own experience how difficult it is to communicate the topics of log, lut and baseISO in a comprehensible way, we still give Sony our "thumbs up" - for their own attempt to shed some more light on the matter...
