In other available LUTs (e.g. from NHK/BBC or NBCU), the name follows the schema indicated by Andrew, i.e. primaries and transfer function for input first, output second. For the "standard use case", i.e. a ready-to-play file, you would therefore chose a LUT which has no "linear" in the second token. Also, they are configured to be applied without further "tweaks", however that may depend on how the source image was processed. Often, you may find an accompanying document explaining the intended use for the supplied LUTs. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
