With DNx36 not supporting 1080i60 or 1080p30 what are people using for a 1080i proxy format?
The next DNx flavor is 100Mb... way too big! ProRes proxy supports 1080i but we'd prefer a cross platform encodable format. After that it's XDCamEX 35Mb but a long GOP proxy would be asking for trouble, no?
Unfortunately SD DV25 anamorphic may be the way to go.
