30p hdv render settings

Kazzy wrote on 3/21/2012, 6:01 PM

Need help. Shot an event in 30p hdv for a change and rendered it first to dvd architect 24p widescreen and changed the frame rate to 29.97. If I go standard mpeg widescreen then it does not show an option for progressive scan.
After render the video looks OK but not as good as I thought it would.
Any ideas of what the settings should be?

You need to be more specific. It is very unclear what you're doing.

You shot in 30 PsF on say a Canon HV-20/30/40? I think PsF is the only way to get 30p in an HDV format.

Are you rendering in Vegas or DVD architect?

30 PsF is stored as interlaced. It takes a special process to upwrap it to progressive. The canon camera comes with software to do that or you can use Cineform's capture/convert utility but that costs money.

Otherwise when you put it on the timeline in vegas it will look like interlaced footage. I am not sure since I haven't tried it, but maybe if you disable resampling and set your project properties to 30p and "blend" deinterlacing method Vegas might unwrap it properly.

Once you have real progressive on the timeline you should use Vegas and not DVD Architect to render it to what you want.

Are you rendering for DVD or what? If DVD use the DVD Architect Widescreen template and customize it for progressive.

Hello,
the footage was shot on Canon XH-A1 and their term for it is 30F. I am using Vegas to render to DVD architect specs. Their is also 720P footage from Canon 60D DSLR on the timeline as well.
I am seeing posts that say to disable smart resampling, etc. but am a bit confused.
I normally shoot 24P so this is new to me.

DVDA will not accept 30p files. But you can render 30p to 60i and Vegas should take each frame and just split it into 2 fields so you shouldn't notice on playback. I'm not sure but you may have to make sure re sample is disabled.

Just did a test and putting 30p into 60i is not a problem, even if you leave smart resampling on.

As for the Canon 30F, I have no idea how Vegas will handle it. But once you have all the media in correct 30p the way you want it, edit away on a 30p timeline and just render to the DVDA widescreen 60i.

Thanks for your help. I completed a dvd the other way I mentioned and it looks good but not great. That is why I wanted to see if their was a better way to produce from this format. I will give your suggestion a try. Another thing I noticed is that the 60D 720 footage frame rate is 59. something per second. (double ntsc).

I see-you have some 60p in there too. With those you definitely want to turn off resample for all of them and then one of two things:

1. Leave the playback rate alone so Vegas will drop every other frame to achieve 30p. You may or may not want to use BCC, After Effects, AVISynth or whatever else to add motion blur

2. Set the playback rate to .5 for smooth slow mo.

First of all, I don' t think there is an HDV camera out that isn't shooting at 29.97 when they call it 30p. True 30p is just a couple of older firmware Canon DSLRs and pretty much nothing else. You were shooting at 29.97 so don't worry.

Second, when shooting 30p (29.97), see if your camera doesn't have a "shoot at 30p but flag and identify as 60i" mode. On my Sony HVR-Z7 I select this mode by choosing 30p from the interlaced options. Using this mode will allow the footage to smartrender (into a 60i HDV or 25Mbps .mxf template).
