#DOUBLETAKE APP 720P#
48 kHz is also the standard audio recording sampling frequency standard in all current consumer and professional camcorder formats for both HD 720p and HD 1080p. Amazon Video Direct via Amazon Prime as I covered in this article.Īll of the destinations listed above demand 48 kHz as I have covered in many past articles.On the other hand, 44.1 kHz doesn’t match established audio sampling standards in standard video destinations like: Offer only lower bit rate compressed recording at H.264 instead of offering higher bit rates in H.265.Offer only compressed AAC/M4A 48 kHz audio instead of PCM uncompressed 48 kHz audio.Here is a list of features which are okay to limit the freemium version of DoubleTake:
In my humble opinion, with only offering 44.1 kHz, DoubleTake is like offering 1900×1000 instead of the standard 1920×1080. It is completely reasonable to have a reduced, non-premium feature set in a freemium model, but it’s just wrong to be non-standard. The problem is the current version uses an audio sampling frequency that is non-standard for video. Currently for iOS on certain iPhones, the free DoubleTake app offers framerates like ≈24, ≈25 or ≈30 fps at VFR, as covered in prior articles.
As announced at Apple’s WWDC in June 2019, DoubleTake is an app from FilMiC Pro which allows multicam recording in up to 1080p.
