![]() Amazon Video Direct (covered in this article )Īll of the above demand the 48 kHz standard (some at a minimum).Whether you are going to edit the video or not -and even if you only use the non-standard 44.1 kHz footage from Ecamm Live (Pro), if you ever want to send the footage to a venue like the following, you’ll be in the exact same hot water:.Upsampling must be avoided like the plague. You will be forced to upsample the non-standard 44.1 kHz audio from the Ecamm Live (Pro) footage to the standard 48 kHz. However, if you need to edit footage recorded with the current Ecamm Live (Pro) with audio/video recorded with a consumer or professional camcorder, you will have a mismatch.If you are only going to stream -not record locally or edit or send your footage to a professional video venue which demands proper 48 kHz audio sampling, probably nothing. As my mother taught me as a child: Two wrongs don’t make a right! However, those venues fortunately also accept the standard 48 kHz sampling rate. Indeed, there are online platforms that accept non-standard audio sampling rates in videos, including Facebook, YouTube and Vimeo. Yes, I dare to use the term incorrect because 48 kHz is the absolute worldwide standard sampling rate for digital audio for video. Sadly, the audio sampling rate is currently incorrect in both versions of the Ecamm Live apps. Audio sampling rateĪfter many months of requesting Ecamm to fix it in Ecamm Live (Pro), I can no longer remain silent about it publicly. However, I do lose sleep over the next topic: audio sampling rate. That’s something I have covered in past articles and won’t repeat here in this focused article. Neither Ecamm nor FiLMiC Pro has paid attention to this request and I haven’t lost much sleep over it, since it doesn’t actually cause any problems as long as we understand that they are VFR targets and all will be well as long as we know how to handle VFR recordings later. I confirmed that using the Invisor app for macOS which I reviewed in September 2020. I thank Alejandro Becerra of Live Stream Miami for sending me an Ecamm Live raw recorded clip for me to confirm that indeed it is VFR. ≈25 (although PAL-derived, the chosen worldwide standard framerate for ).I have requested FiLMiC Pro and Ecamm to display the VFR rates with the approximate symbol in front, like: ![]() VFR is a legitimate method to make compression more efficient for most productions as long as we know what it is and how to handle it. …is because (as I have covered for smartphone video creation tools before in past articles), the actual encoded video from Ecamm Live (Pro) is actually VFR ( variable framerate ), just like in most professional camera video apps on Android and iOS, i.e.
