I exported a MOV file through Apple Compressor: @ 25fps, H264, 1920x1080, 35 Mbit/s and PCM Stereo sound. I needed however to get a smaller version of the clip so I used compressor with the above file as a source. The output that I wanted was to be @25 fps, 1280x720, AAC audio (not quite sure about required bit rate).
After submitting the above in Compressor and choosing the option "frame rate same as source" I get a MOV file which complies with the above requirements however the 25fps are actually half, as every frame is repeated. This results in a jaggy futage as if it was 12fps and not 25fps (which its is)
I tried various settings in Compressor but seem always to get (effectively) half the input's frame rate! There is nothing I can see in Compressor that would indicate this will happen.
Why is this? How can I get a real 25fps compressed clip?
Following are the settings I use for the reduced size clip that I want to produce.
