Hi,

 

I compressed a video using Final Cut Compressor.  The original file was 1920x1020 ProRes.  I needed to convert the file to an actual size of 1920x1020 with H264 video codec and AAC audio codec.  I put those settings into Compressor and compressed all of my files.  When I uploaded the files, the size was 1920x1080 (1888x1062). This was a problem for our online video distributor because they said the file was NOT actually 1920x1080 but 1888x1062.

 

Here's a screenshot:

Can some tell me what I did wrong so I can fix the files and have the encoded size actually be 1920x1080 with H264/AAC?

 

Thanks very much,

Cyndi

    Not sure that you did anything wrong here. The "Inspector" window indicates the clip was encoded as an anamorphic 1920x1080 (1888x1062) file. This means the file was encoded using an 1888x1062 encode matrix but displays at 1920x1080 in any "new technology" media player that can apply the embedded PAR values like QT X or iMovie '08/'09/'11. Further, since the "Current Size" embedded in the clip is 1920x1080, the same file will also play correctly in so-called "old technology" apps like QT 7 or GarageBand. If you are simply saying you want the file to be non-anamorphic, then change the encode geometry so that the file is both encoded and displayed using the same desired dimensions.

    Hi Jon,

     

    So glad you answered!

     

    This may sound like a stupid question but how do I do that? I don't know what/how I made it be different in the first place.  I see on the bottom how it has size and actual but the AOL media folks were adamant that it was the wrong size.

     

    They are on PCs.

     

    Thanks so much,

    This may sound like a stupid question but how do I do that?

    The question of "How" usually depends on the application and/or version of the app you are using. Some apps will automatically default to anamorphic encoding if the source file was also encoded anamorphically. Others use anmorphic settings if you select a "standards" based output dimension option. In most cases the easiest way to avoid anamorphic output is to simply select the "Custom" dimensions option if available and enter the desired values for width and height. In this case, the encode and display dimensions are set to whatever value you enter and the PAR is reset to 1:1 which means the file plays at the encoded dimensions no matter which type of player is used.

     

     

    I don't know what/how I made it be different in the first place.

    It is most likely that you merely accepted the default options for the encode of a sourced file that was itself anamorphic and which was not automatically cropped for any reason.

     

     

    I see on the bottom how it has size and actual but the AOL media folks were adamant that it was the wrong size.

    These values indicate the current default display dimensions embedded in the file upon opening ("Normal Size") and the current display scaling ("Current Size") which may or may not have been changed by the user since opening the file in QT 7 or similar apps. These values are ignored by QT X and similar apps which rely on an aspect ratio value to scale the width of a display based on its current height.

     

    As to AOL requirements, I am not sure if you are referring to specific upload limitations or some sort of anamorphic conversion issue if the file are transpoded to another compression format (e.g., Flash files) following upload for public display. In either case, exporting the files as non-anamorphic clips at specified dimensions is the same—simply use a "custom" dimension setting that meets their requirements.
