Best Export Settings for 1080i footage out of Premiere Pro CS4
Hey Everyone,
I am finishing up on a project and my editor is giving me final masters with file sizes that seem way too big. Here’s the info on what we shot:
Camera: HVX-200 shooting in 1080i via P2 cards
Premiere: CS4 which is editing the P2 footage natively.
On export, projects that are ten minutes in length are coming out with a file size of over 100GB. That can’t be right, can it? Our finished product needs to be a high quality quicktime file as well as a dvd.
Taking into account the above, here are my two questions:
What export settings should we use for a high quality 1080i quicktime file? (needs to be playable on as many computers as possible)
What export settings should we use for the highest quality dvd possible? (I know we’ll have to bust down to 720, which is fine)
Thank you again for any help you guys can provide 🙂
– Matt

That sounds about right for an uncompressed version of 1080i. It runs at a little over 200 MB per second, so doing the math gives about 120 GB per 10 minutes.
Regarding your deliverables, does “most” computers for QTime mean most recent ones? Use H.264, at a moderate data rate (maybe 1000 K(bits)ps), and a frame size that seems compatible. Testing will be required. If it means older computers as well, you may need to try a less demanding playback codec.
DVD-video has a maximum data rate of about 9 Mbps for the audio/video portion. You probably can’t see a difference over 7 Mbps, even with fixed-rate. How much will fit depends on how long your video is (math may be required). And, to be accurate, you will actually downsample to 480i. 720 is still HD.

Hi Matt,
If you are getting masters (usually meaning that this is the highest quality export) 100 GB for 10 minutes is actually not that big, assuming you would be getting uncompressed content.
For Quicktime playback (live event) start with H.264 at 10Mb/s.
For distribution, you have to play with settings, the more motion, the higher the bit rate.
For DVD export at 10 minutes, 7.5 Mb/s CBR.
