30P --> 24P Final

Guys to be able to do good slo-mo and have 24p in the end, does it not make sense to always shoot 30p and then for the final output (BD for example) render to 24p

Shooting 30p versus shooting native 24p

Any advantage to shooting either framerate that you can think of - when the final product will be 1080 24p

Thanks
Paul

The motion rendition of 24P, 1/48 shutter is different from 30P. it's a different feel.

72 or 120 is best, of course, but 30p would be a small improvement for most purposes, yes. Be very careful to only use it for slow motion. Converting 30p to 24p at regular speed is disastrous.

For the best results, set your camera to 24p and overcrank with the S&Q menu.

This will give you highest data rate at your playback speed.

This is because the EX1 bases the data rate to 35Mbps for your chosen mode, and increases it proportionally when you overcrank.

If you base your footage on 30p and then slow down to 24p in post, your playback data rate goes down 20%, which, at least theoretically, will reduce your picture quality.

I absolutely agree, and yet somehow when episodic TV shows are shot in the US, they are often shot on film at 30p. In spite of it not really being technically possible, somehow they are converted to 25p for PAL audiences.

This conversion is done with some extremely expensive conversion hardware that is beyond the financial reach of most of us, but the conversions do end up looking pretty smooth.

None-the-less, if you are going to end up at 24p, shoot in 24p. You should only use 30p and 60i for stuff you want to slow down. 60i can be converted to 24p, but it won't look as good as if you just shot it in 24p to begin with.
