F.A.Q.

Quicktime is dead !

Yes that’s why there is AfterCodecs ! It doesn’t need Quicktime (and never will) to run so you should be safe now ;)

There’s an issue with my render, what should I do ?

Please open a new ticket about AfterCodecs, don’t forget to send the .log file generated by AfterCodecs and information about your setup !
Please also make sure that you are not using a forbidden resolutions, see Technical specs

The ffmpeg download doesn’t work, what should I do ?

Retry the download button or follow the manual instruction in the .pdf given with the AfterCodecs downloaded archive.

Quicktime Player doesn’t play my video !

Be sure to be using x264 (and not x264 RGB or x265), with the quality slider <= 98. If it still doesn’t work, choose the H264 Main Profile

Can I use my own ffmpeg command line ?

Not yet, sorry. If you want to discuss this feature and what you need, please open a new ticket :)

Can I have a preview of the final file size ?

Only on PPro / AME as of now

Is x264 different from H264 ?

H264 is the norm and x264 a software encoder that implements H264, faster and of better quality than encoders from Adobe or Quicktime

AE : How do I render in 16 bit per channel ?

Be sure to set your AE project in 16 bpc, it will export to AfterCodecs in 16 bpc (even if you select “Millions of Colors” instead of “Trillions of Colors”)

Where is the Hap codec ?

Select “[A] Hap” and export in RGB in the AE settings. Exporting in RGB+Alpha on AE (or ticking Export Alpha Channel on PPro / AME) will automatically switch the codec to Hap Alpha.
