This is a special case involving high speed video that does not involve bit rate.
For high speed video, affordable cameras record at high frame rates with reduced resolution - high bit rate recording
. The cameras, that I am familiar with, process the high frame rate recording to produce a 30 fps output video file with the same low resolution used for recording - low bit rate video playback
For example, a Casio Ex FH20 records at 210 fps with 480 X 360 resolution at a high bit rate. It produces a video file of 30 fps and 480 X 360, a low bit rate video file. When played back at 30 fps the motion is only 1/7 speed of the true motion, = 'slow motion'.
I would like to identify the unknown cameras used for Youtube slow motion videos or at least get an idea of which cameras might have been used. Is the 'Stats for nerds' at all useful to help ID the camera?
Case I - Resolutions seem to match.
Right click on the video and select 'Stats for nerds'. You will see 480 X 360 on this video. I believe that the high speed video camera that produced this video is probably the Casio FH20 because it records with the same 480 X 360 resolution. Is that a reasonable association?
Case II - Resolutions don't match.
However, when I look at this second Youtube video, where the recording camera is stated to be a Casio FH25 at 240 fps that records 240 fps with resolution of 448 X 336, there is no relation between the recording resolution and the 'Stats for nerds' resolution. ?
'Stats for nerds' on this video shows a resolution of 854 X 480. That resolution does not appear to be related to the recording resolution of the FH25, 448 X 336.
BTW - this is one of the best close up videos of a golf ball impact that I have seen produced with the affordable HSV cameras- the Casio cameras with very fast shutters (to 1/40,000 second).
