Apple’s recent transition from 32-bit to 64-bit technology in macOS Catalina has led to the drop of support for several legacy video codecs. Most notably affected are two codecs which are no longer compatible with Apple’s 64-bit operating systems:
- Motion JPEG (M-JPEG, MJPEG)
This was previously our preferred option for files containing alpha channels or transparency. Since Photo-PNG is no longer compatible with Apple’s 64-bit operating systems, we recommend using one of the options listed further down in this post.
– Motion JPEG
While more obscure and not as widely used, we’ve discovered that some video encoding software might display its output setting as “Photo-JPEG”, but unbeknownst to authors, is actually creating an MJPEG variant instead. Some versions of the Motion JPEG codec may still be functional, but must be OpenDML only.
LATEST FILE PREPARATION REQUIREMENTS
Please see our updated documentation which outlines our currently approved video codecs and file settings:
Approved Video File Formats:
- Quicktime MOV (.mov)
- MP4 (.mp4)
Approved Encoding Formats:
- Photo JPEG
- ProRes (442, 442HQ, 4444, 4444 XQ)
ALPHA CHANNEL/TRANSPARENCY OPTIONS
With Photo-PNG no longer supported, we now offer a few solutions to providing files with an alpha channel, transparency, or luma/chroma matte.
Preferred option: encode the file(s) using the ProRes 4444 or ProRes 4444 XQ codec.
Alternative option: provide a separate matte file (such as a black-and-white luma matte encoded with Photo-JPEG or h.264) allowing customers to key the transparent portion manually.
SOLUTIONS FOR EXISTING MARKETPLACE ITEMS
Many items on the Videohive Marketplace are encoded using the Photo-PNG codec, which is no longer compatible with Apple’s 64-bit operating systems. Whether you’re a Videohive author or a customer who is having trouble using an item you’ve downloaded, we’ve offered some solutions below to deal with existing items that are affected by the change:
Authors: We’re advising authors to re-encode their more current and most popular items to one of our approved codecs from the file preparation guidelines.
Customers: If you’ve purchased an item that is no longer compatible, the file can be
converted to a compatible format that will hold an alpha channel using video conversion
software such as Adobe Media Encoder.
