In 2015, with the Galaxy S6, Samsung made an excellent decision: They started encoding slow-motion videos in real-time and with audio.
This means the resulting file has the same frame rate that was recorded from the image sensor, and a slow motion effect can be added to the desired sections through a pre-installed video editor. This is the behaviour the iPhone used since they introduced slow motion video in 2013.
This way, a "slow motion" video can both be treated as a slow-motion and a real-time video. An 120fps video recorded on the S6 in 2015 can take advantage of the 120 Hz screens in modern smartphones by being played at real-life speed and looking extra smooth.
In any video editor, 100% speed means real-life speed, not 400% or whichever number. Any confusion is cleared. I was glad Samsung did that. This is something Apple did right before Samsung. Currently, Xiaomi is thankfully encoding slow motion videos at real-time speed.
But Samsung later reverted back to the inferior behaviour of slowing down the video when encoding it. On the A52, the 240fps image sensor output is saved as a 30fps video file, meaning 800% playback speed equals real-life speed.
Is there anything one can do to get back the real-time encoding? If it requires root, it is OK.
