Many thanks – I had the same problem. I used PavTube to convert MTS files (from a Sony Nex-7) and although the exporeted 422 Quicktime *seemed* okay on inspection – the “conform” button was still greyed out after importing into in Cinema Tools. As an intermediate step – I used Compressor (Custom setting I created using 50fps, 422), before going to Cinema Tolls and hey presto – very grateful!
