JPEG2000 mov not importing

[huyt63327659]

So. My last problem with jpeg2000 movs playing in PP but not in AE resolved itself by restarting the pc.

But since updating to CC2018 all CC products refuse to work with jpeg2000 in a mov container. Not only in Windows but also on Mac. CC2017 imports them fine, CC2018 no chance ("No importable streams found" or something I use the German version). I could use Media Encoder 2017 to re encode everything, but since it is a whole library of video elements that would be rather tedious.

Did Adobe just end support for jpeg2000? Or is there something I overlooked?

You can find an example file here: WeTransfer

Yes.  It happened with the most recent Creative Cloud update.  Many older, but still widely-used codecs were dropped.

As far as I know, the best way to re-gain access is to revert to the CC 2018 update that was released BEFORE April.

Here you have the new list of the supported codecs:

Dropped support for Quicktime 7 era formats and codecs

Anyway, considering that a lot of templates are build with JPEG2000 files (because they supported the alpha channel and they were quite light), if I buy one and AE says something like "After Effects error: Source file has no importable streams. Please check that it is a valid video/audio file. ( 86 :: 1 )" we have a problem.

So my solution is this:

1. Download Adobe Media Encoder CC 2017 from the Creative Cloud App

2. Convert the JPEG2000 files setting the Quicktime container and the PNG codec, which is lighter than Animation or Cineform

3. Replace the file inside the After Effects project of the template.

I've literally spent hours trying to figure out a solution to this - i'm trying to get some legacy Quicktime JPEG2000 (with alpha channel) files into AE in an old project. I tried different video converters, been searching the web, hours and hours.

This solution worked perfectly, and was the easiest. Thank you!

Or, whenever you need to use a quicktime file with a Jpeg2000 codec (or similar codec no longer supported), you could use After Effects CC 2017. ie. you could have both After Effects CC 2017 and After Effects CC 2018 on the same machine and use CC 2017 when needed. That way the videos wouldn't need to be re-encoded (which would possibly reduce the quality or increase the file size). The downside is that there could potentially be security issues if the codec(s) are no longer supported.

In case anyone is still having this issue:

Apple's Compressor app will convert JPEG 2000 mov files. I just successfully converted mine to Prores 4444+ (with alpha) with Compressor v 4.4.4. I hope that helps someone. Cheers!
