Anyway, its annoying that if you preview your XDCam Material with the Sony Transfer there is no large preview available you can send to an external viewer or monitor.
Thats correct. The XDCAM Transfer app downloads and thereafter lets you view the low res proxies so as to make your logging decisions, those proxies are not really of high enough resolution to support large screen playback.
The workflow is to view the proxies, mark/log the clips needed and import … the process is sequential: view a clip, mark/log areas for ingest, press import, view the next clip, mark/log areas for ingest, press import, view the next clip, … etc. By the time you have finished logging then most of your media will already have imported in the background and you can begin your edit; the remaining clips will continue to import whilst you edit.
