workflow to convert DVCPROHD, 1080i to DVCPROHD 720P

[Luke Maslen]

Hi Mason,

This is a good but frustrating question as there are lots of TV’s which can take a 1080i signal and display it as 720p and yet I cannot find an SDI convertor which does this. I had a quick look at the convertors in decks and also couldn’t find a format convertor to do this but maybe I missed something and someone else in this forum will report it. Can you tell me what workflow you have in mind where 1080i to 720p conversion would be helpful?

The best universal QT format is uncompressed 2vuy for 8-bit or uncompressed v210 for 10-bit. Uncompressed is essentially a raw format and should be able to be ready by any QT-savvy application. Final Cut Pro HD includes Apple Uncompressed 4:2:2 codecs and we also have our own, both of which will enable you to open movies in the 2vuy 8-bit and v210 10-bit formats. This is the nice thing about using open standards in that it makes it easy to move files between systems regardless of the software or hardware being used.

Luke,

Thanks for the fast reply and terrific information. I’m using the latest version of FCP 5 and your BM codes with a BM HD link card.

When I try to export a clip from 1080i DVCPROHD to the BM 8 bit (2VUY), I’m getting a dialogue box that tells me it’s medium quality. Is that OK?…can I get “Best” quality? Same thing happens if I go to the botttom of the list and select, Uncompressed 8 bit 4:2:2.

Should I be using a custom size 1280 X 720? or wil lautomaic cover that?

thx..Mason
