29.97 footage in a 23.98 project?

[Enrico Lappano]

Thanks Shane! I’m looking forward to trying it out.

If your 29.97 footage was shot with a 7D than it’s 29.97p and not the typical “videoy” 29.97i. 23.98p from 29.97i is arguably doable (I’d argue against it) but 29.97p to 23.98p is asking for poor results. The only way to get acceptable results is to use optical flow tech in Compressor, Twixtor and the like. If you have complex imagery and crossing motion it will look bad.

I suggest hitting the easy button here and continue with 29.97p. At least test at 29.97p to 23.98p conversion with a moving subject matter and decide based on that.

I don’t believe Nattress uses optical flow tech… correct me if I’m wrong.

Oooo…right. The Nattress plugin is for INTERLACED material. It won’t work on 29.97 progressive.

Using Compressor, and frame controls, what are the best settings for a 29.97 to 23.98 conversion test?

Which Nattress filter are you referring to Shane?

I used the Nattress Graeme G Film Converter to convert DVCPRO HD 108030p to ProRes HQ 1080p24. Looks great after ran some tests and tweeked the settings. If you download the manuals for that and Film Effects filter it’s pretty straight forward.

I have not yet tested this filter on interlaced material, ugh like the iPhone, a HD Flip Cam, and other consumer HD formats of the day.
