Premiere Pro CC Projects Will Not Be Backward Compatable

I found the following work-around: not perfect, but quite good.

• Premiere 6.5 projects can be directly opened in CS6 or earlier just by changing the extension from .ppj to .prproj

• Make a copy of the original .prproj file and name it Name_audio-only.prproj
•  
• Export sequence(s) as FCP XML from CC - multiple sequences can be selected OR select Project Panel to export entire project (Attention: Most video - even intrinsic ones like motion, opacity etc. and audio effects are not correctly translated! Check beforehand that all 3rd party plugins are installed in all versions of PPro!)
•  
• Save a copy of the project as Name_video-only.prproj and delete all audio tracks or audio clips from all sequences that contain video effects
•  
• Close PPro CC project

• If the PPro CC project file is compressed, add .gz as extension and extract with 7zip
  • To disable compression in CC:
    • Mod note: This text was removed as it is against community guidelines to condone the use of internal debug tools. Please avoid this in the future. Thanks.
• Open in Notepad++

• Edit version number change (4th line) from 26 to 23 or 24 and open the project in PPro CS5.0.3 or PPro 5.5.2 and save it.
•  
• If there should be a color picker dialogue box while opening click Cancel (as this is most probably for Adjustment Layer which are not supported in CS5.5)
•  
• If PPro CS5.5 shows a Log of non-translated effects etc., copy and paste them into a text file with the project name for later reference. 
  • PPro Version numbers:
    • 23>CS5
    •  
    • 24>CS5.5
    •  
    • 25>CS6
    •  
    • 26>CC
    •  
    • 27>CC 2014
  • A simple change to 23 and opening it directly in Adobe Premiere Pro CS6 does not work! (Liegt wahrscheinlich an den Audiotracks, da Projekte mit Sequenzen, die nur Video enthalten, teilw. geöffnet werden können.)
  •  
  • It is possible to open a PPro CS6 project directly in CS5.5 by editing the version number from 25 to 24.

• Open this project Name_video-only.prproj in Adobe Premiere Pro CS6 and convert it to CS6 project - now you have all the sequences with the supported video effects
•  
• Import FCP XML project file(s) into PPro CS6 and copy the audio tracks from the corresponding sequences (or vice versa: copy video tracks so they align synchronously again)

• Gotcha’s:
  • Through Edits, Adjustment Layers, Time Remapping, 3rd party filters, plugins, transitions may not be correctly translated!

PRPROJ File Associations

After installing an update to PPro, Windows will change the default program to the latest program version, e.g. CC. If you want to revert those to CS6, you cannot simply do it with Rightclick>Open with>C hange default program..

There is a way to change the setting in the Windows Registry:

Open regedit.exe as Administrtor

HKEY_CLASSES_ROOT/Adobe.Premiere.Pro.Project. >  shell/open/command and change the path in “” to the correct program version.

You can also do a search in the section of HKEY_CLASSES_ROOT/Adobe.Premiere.(with various endings following the word "Premiere") and change all remaining instances.

To go backwards you will probably need to export an EDL which doesn't care what version created it or is opening it. You will probably lose most of your FX, Transitions, etc that are not supported in the earlier version that opens the EDL... but most everything else should be in tact.

Generally speaking, projects can be opened in later versions, but not older versions.  It's been that way for a long time now, regardless of license.

I see the same information you cite.

Look under Desktop Apps, "Which CC applications support export to CS6?"

Do I remember a post saying that Premiere CC will export to CS6?

Kevin , can you clarify?
