DVCPROHD1080i60 to H.264 SD720 4:3
on Sep 3, 2011 at 3:33:43 pm

Ok, I'm sure this has come up before but I didn't have any luck finding it on the forum. So forgive me.

I need to make DVCPROHD 1080i60 files into SD 720x486 4:3(poss 16x9 also).
Since this is a TV commercial for broadcast and will be uploaded via ftp they need to be QTH.264 files.

I tried a few from the Suite 2 timeline with not the best success and even some crashes crashed I even tried thru QTpro which worked nice although it made my 720x486 movies(640x480)

I'm new to DVCPROHD and the "UPPER fields" it creates. Do I need to select interlace as well?
Anyway Any suggestions would be great!

How do you want to convert the 16:9 to 4:3? Letterboxed with black bars at the top and bottom? Or cropped, losing image at the right and left?

I guess the easiest way would be to use the realtime Pan&Scan features of Suite 2 to place your 16:9 HD material in a 4:3 SD timeline to actually scale and crop to your needs. Of course the issue of going from 60i to 29.97i is another topic; not sure if Suite2 does handle that. But of course you could do such a conversion in e.g. Compressor or Episode or AE, depending on which software you have available.

Athough the codec /config setup is 1080i60 it's still in 29.97 format. (got me on that one)

I just need to crop it 4:3. I set up the Grx in AE for SD safe knowing I needed both HD and SD versions.
I've never tried the pan-scan thing in media100. Maybe I'll try that. As well as in AE.

Thanks for the guidance on this FLOH. After trying Compressor, QTpro, AJA, AE... The best conversion from 108Oi HD to SD 4:3 720 is to copy the project from the 1080i timeline and paste it directly into a 525i NTSC program. I did have to change the config to ntsc 601 or else the COLOR was too saturated. It will render it quickly and it looks great!
