Anyway, on this topic, is there a way to definitely read the bit depth used to encode a file? According to Arri, the ProRes 444 clips created by the Alexa camera are written using 12 bits. This is documented in many places on the web, including this forum post. But somehow, ffmpeg identifies these files as yuv444p10le and the image looks correct. https://www.arri.com/forum/viewtopic.php?t=127&p=266 <https://www.arri.com/forum/viewtopic.php?t=127&p=266> If the image were truly 12-bit, and ffmpeg decodes it as 10-bit, I expect the image would look wrong. According to the MediaInfo developer, there is no way to definitely read the encoded bit depth, and therefore he has removed that info from the MediaInfo tool. https://sourceforge.net/p/mediainfo/discussion/297610/thread/4bc21b18/#cd3a/2395/563e/1fec <https://sourceforge.net/p/mediainfo/discussion/297610/thread/4bc21b18/#cd3a/2395/563e/1fec> <https://sourceforge.net/p/mediainfo/discussion/297610/thread/4bc21b18/#cd3a/2395/563e/1fec> <https://sourceforge.net/p/mediainfo/discussion/297610/thread/4bc21b18/#cd3a/2395/563e/1fec> <https://sourceforge.net/p/mediainfo/discussion/297610/thread/4bc21b18/#cd3a/2395/563e/1fec> _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
