On behalf of my blog readers, I went to Catalunya Square today where are two places showcasing the S7 and ask them about the Slow Motion video recording mode. People wanted to know whether the Samsung Galaxy S7 slow motion mode is native 240fps or is captured at 120fps and converted to 240fps (interlace conversion).
None of the what so called Samsung Experts had an answer for me. They told me that it captures slow-motion videos in 240fps, but they didn’t know whether it’s the original frame-rate or interpolated from 120 fps. I wan manged to do two things. Get a screenshot of the video info page, and second, a kind lady there was kind enough the download a video metadata app and check it for me.
Here are the two screenshots from the S7 phone:
As you can see from the first image, the recorded video that was capture in Slow-motion shooting mode was captured at 226.42 fps. Of course that doesn’t really tell us whether it was originally captured in 240fps or 120fps.
In the 20160225_101608.mp4 video, 10 (Seconds) x 226.42 (Frames) = ~2264 frames were captured. The total size was 85.89 megabytes (~87,951 kilobytes). Each frame is equal to ~39KB per frame.
For me it seems a bit low for 240 fps, but I open this debate for you to help me out, I am not such a math genius nor have deep understanding in all the video compression stuff. Please share your opinion in the comment section below and help me solve this debate- Thanks!
Here’s the original video (off-screen) I’ve taken.
I’ll update this post when more information is available to me.
