What is this "codec PNG image" that is contained/wrapped by the .mov format? What are the video and audio properties of this video...frame size, frame rate, interlaced or progressive, pixel aspect ratio, et al.
It sounds like you have Premiere Elements 12 is running on some version of Windows with QuickTime (latest version) installed on the same computer as Premiere Elements. Great. Requirement for QuickTime met.
Where is this PNG.mov coming from? And what type of .avi were you thinking to convert to?
Premiere Elements 12 Publish+Share/Computer/QuickTime does offer an export with a PNG video codec with the .mov file extension. I am in the process of exporting my Timeline to that type of file and then determining if I can import that back into Premiere Elements 12 project.
When your png.mov will not install into Premiere Elements 12 on Windows 8.1 64 bit, what is the specific message that you are getting from the program at that time.
More shortly after my export of the png.mov is finished. Any minute now.
Add On....The png.mov produced by Premiere Elements 12 Window 7 64 bit could be imported into a Premiere Elements 12 project. I am now going to my laptop which has Premiere Elements 12 on Windows 8.1 64 bit to do the same thing and see what happens there. Back soon.
The png.mov exported from Premiere Elements 12 Windows 8.1 64 bit imports into a Premiere Elements 12 Windows 8.1 64 bit project here with problem.
QuickTime (latest version 7.7.4) is installed on Windows 7 64 bit as well as Windows 8.1 64 bit along with Premiere Elements 12.
We need to look into the properties of what you are placing on that Timeline. Just like all .avi files are not created equal, that case may be made for the use of a "png codec" from varied sources????
You can get video and audio properties of this MOV file by clicking the link to the file: http://www.detfilmsshockwave.com/DVExplosion01.zip (11,617,621 bytes)
This archive contains only one free video in QT MOV format: DVExplosion01.mov.
Applian FLV Player installed on my PC will display for menu item Interface -> Codec Information -> Codec Details next info for this file: "Codec: PNG Image (png)". I don't know what that means!
I have been trying since yesterday to placing this downloaded file on Timeline Adobe Premiere Elements 12, but an error occurred while importing this file.
So I decide to reinstall QuickTime v.7.7.4 again and reboot my PC...
It's a miracle that no more errors or failures!
Thank you, ATR!
Thanks for reporting the good news of your success with the PNG.Mov file into Premiere Elements 12.
