compressor does not seem to compress really
It really does. Depends on what you feed it.
For example: If the input file is say, a 15 minute 1080P30 Pro Res clip, the file size would be nearly 17GB. That's because for that format, Pro Res 422 has a data rate of 147 Mbps. If you used the 1080P30 video sharing preset, Compressor would turn it into an h.264 file with a data rate of 20 Mbps. The output file would be about 2.3 GB…much smaller.
But it you were to feed it a 15 min 1080P30 H.264 file already encoded at 20 Mbps (about 2.3 GB) and applied the same preset, it would output…a 2.3 GB file. So in that case you'd be right.
