Creating DG FastChannel – Drop Box HD Compressions?

[Bill Nelson]

just SD only, 720×486 out of a Mac Avid 7.2 SDI. should be a piece a cakewalk

I’ve got an SD setting but earlier today I’ve received different specs for SD then they’ve sent me previously so I’m looking into that.

I had 25Mbps previously. The sheet I just got is 18Mbps.
Was 4:2:0. Now I see 4:2:2
Was IBBPBBP GOP and now it “seems” to be IBBBPBBB

So I’m going to try to get this straightened out ASAP.

I spoke to my contact at DG and

HD is still in testing phase for DropBox. They’ll send out notices when that’s ready to go.
It seems the minimum was raised from 10Mbps to 18Mbps but the Max is still 25Mbps. For that reason I’d do CBR 25Mbps and that passed last time I tested.

GOP structure they say isn’t supper critical as long as it’s 6 frames or more so you can continue using IBBP (which is what I use.

The HAVE changed color from 4:2:0 to 4:2:2 though.
