A 134 MB phone video went out on Facebook, LinkedIn and Threads but Instagram answered only "ERROR" and gave up after ten attempts. Instagram's processor is the strictest about codec, size, frame rate and bitrate, so videos are now re-encoded to the profile it accepts (H.264 and AAC, up to 1080 x 1920, 30 fps, 8 Mb/s) before they are sent to Instagram, Threads, TikTok and X; the other networks get the original. A network that still refuses gets a "Retry on Instagram" button on the post, which sends it again to that network alone. And a network that never confirms is called failed six hours after the post's time instead of staying "processing" for days, so you hear about it.
