4×3 SD / DV or Pro-Res Sequence?

[Craig Seeman]

I’d use a standard def sequence but not DV. You can certainly do an 8 bit uncompressed or Pro Res standard def sequence. I’ve done this for Broadcast spot delivery in SD.

Second that, I see no reason whatsoever to use a DV sequence. Yuck. All your renders would be DV, that’d be a sin. I use ProRes SD.

Yeah, that makes the most sense. I’ve been fooling around with it, and I can’t seem to find the right combination of settings. In the sequence settings, I have selected Pro=Res 422, square pixels, Field Dominance/None, but I am befuddled as to what to choose for Frame Size / Aspect ratio. NTSC 4:3 or CCIR 601 NTSC, Etc., Etc? I’m getting some strangely elongated images on my monitor.

Also, no matter what I do, I’m getting the red bar, so I can’t play my timeline without rendering. If I edit in a DV sequence, I at least get some realtime. Now, If I start with a DV sequence, and just change the compressor to Pro-Res, that seems to work pretty well.

Chris I believe the 16:9 SD is something like 843×486, If you need 4:3 (720×486) then you will need the crop or letterbox.

Good Luck

If I load the preset for ProRes422 NTSC, the video displays properly in 4:3 and I get some realtime (green bar), but the preset adds DV properties (lower field interlaced and rectangular pixel aspect ratio), so it’s essentially a DV sequence except it’s rendering in ProRes, I guess.

I’d cut HD and when all is complete, then drop into an SD sequence and render out. That way your client gets a free HD version they never know when they may use and you have less rendering as you cut.

I vaguely remember doing that once and it made a mess of my motion graphics and titles. Maybe I did something wrong. At least part of it had to do with 16:9 HD vs letterbox in a 4:3 SD frame. Suddenly you have all this black on the top and bottom and one has to build graphics with that in mind that one doesn’t do in a 16:9 frame. Of course editing a “clean” HD version might help but I remember motion graphics were impacted as well.

[Chris Babbitt]

It is being delivered in 4:3. I am cropping and re-framing. No point in doing it in 16:9. It was not shot with that in mind.

If you want to make a 4:3 version of your HD project select the following preset parameters:

Apple ProRes 422 NTSC 48 kHz
Sequence Frame Size: 720×480 plus change aspect ratio to: NTSC DV (3:2)
Pixel aspect ratio should be: NTSC – CCIR 601/DV (720×480) anamorphic unchecked
Field Dominance – none
Editing timebase – 29.97
Compressor – Apple ProRes

Create the sequence and drop your EX stuff right in. Just say “no” to the dialogue ‘match sequence setting to the EX clips’. Since your sequence is 4:3 your 16:9 clips will automatically be centre-punched to create your 4:3 version.

Edit, render and export using “current” settings.

Hi Chris,
The codec is not important but for having RT while editing, and in the moment of exporting.
Just make your sequence 720×480 because is going to DVD,
When exporting, of course, NEVER export to DV.
