Vimeo quietly embraces 48 kHz audio; documents non-integer framerates

Unexpectedly and without any press release, Vimeo has resolved two of my few criticisms.

Since I published the article 11 things I love about Vimeo Pro (Pro Video Coalition, November 2012), I have had at least two pending articles about Vimeo’s general service and their upcoming Pay-Per-Vew service, about which I wrote briefly in December. It has taken a while, but Vimeo has finally contacted me to arrange an interview. However, in the meantime, two of my few criticisms have quietly been resolved! It happened without any press release or bulletin.

Proper documentation of non-integer framerates on Vimeo


The above graphic illustrates my recent article Why I pardon rounding of shutter speeds in camera menus, but not framerates! (ProVideo Coalition, July 2012). In that article, I scolded manufacturers for using rounded framerates in camera menus… and continue to warn editors not to believe a camera menu (without verification) when it says something like “24p” or “30p”.

Up until very recently, Vimeo’s online documentation recommended encoding H.264 for upload at 24, 25, or 30 fps, depending upon the source. There was no mention of non-integer framerates like 23.976 or 29.97. Fortunately, Vimeo’s related only flaw was in the documentation, and non-integer framerates like 23.976p and 29.97p have (at least in recent years) always been accepted as “same as source”, so if you uploaded a video at 23.976p, all re-encodes done by Vimeo would remain at 23.976p. Likewise, if you uploaded a video at 29.97p, all re-encodes done by Vimeo would remain at 29.97p. So the only fault was in the online documentation, not in the actual behavior of the Vimeo service. Fortunately, this has been corrected, as seen at So this will prevent anyone from forcibly retiming a video from 23.976 fps to 24.000 fps… or 29.97fps to 30fps unnecessarily based upon literal interpretation of incomplete documentation. Thank you Vimeo for fixing that!

48 kHz audio now recommended by Vimeo!

Up until very recently, Vimeo has strangely recommended the use of 44.1 kHz audio, despite the fact the 48 kHz is the absolute standard for digital audio for digital video in all current production and distribution formats. At first, I had hoped that Vimeo’s recommendation for 44.1 kHz was (like the non-integer framerate explained above) just a question of mis-documentation, but in the case of the audio sampling, that was not the case. Vimeo was unnecessarily resampling 48 kHz down to 44.1 kHz, which made me cringe. I had planned to bring it up during our interview, together with the mis-documentation of the non-integer framerates covered above. Fortunately both issues were quietly fixed just prior to our interview. Now Vimeo is recommending 48 kHz, and only recommends uploading a lower sampling rate in case the original source is (for some reason) lower. Thank you Vimeo!

Now my upcoming Vimeo articles fortunately will be free of these two issues!
