  • Exporting H264 is cutting image off

    Hello All,

    I’ve got a very basic project I am working on for a client. Its a software tutorial. They provide the After Effects file for the intro and outro title sequence in 1920×1080. All I do is open up the After Effects Project file and change the title name to the correct tutorial name for each video and then export out of After Effects as 1920×1080 Quicktime movie for the intro and Outro.

    They also provide quicktime files for the actual screen capture of the tutorial. These are in 1280×720 and are coming from PC. I throw everything down on the FCP timeline, I scale down the After Effects intro and Outro to the 1280X720 and “Send to” Compressor using H264.

    The problem is that the screen capture of the tutorial is getting cut off by the same amount no matter what I change the sequence settings in FCP to or any of the Export settings in Compressor. I have tried to change the sequence settings several ways in FCP, (one of the sequence settings you see below) and scaling everything to the proper size before sending to Compressor. I have never seen this problem before. It doesn’t make any sense because the After Effects intro and outro files are fine in the H264 export. Even the preview window in Compressor shows a perfectly fine preview no matter how I change the sequence settings in FCP.

    I have kept pixel aspect ratio square because this is going out to Youtube.

    One of the FCP sequence settings are:
    960×720
    Aspect Ratio HD 960×720 (16:9)
    Pixel Aspect: square pixel Anamorphic 16:9 (checked)

    MAC OS X
    Version 10.5.8
    2×3 GHz Dual-Core Intel Xeon
    FCP 7

    It looks like the problem is your sequence – it’s an anamorphic HD sequence – 960×720. The pixels aren’t square and by switching them to square in compressor,you’re cutting off the sides. 😀

    What you need to do is create a sequence that’s either prores or uncompressed at a full 720- 1280×720. Copy and paste your footage into that. That should fix it.

    Best,
