30p to 24p 5D Mk II File Workflow
Thanks Dan for the excellent clip and for Jenn for hosting the raw 1080p file.
Does anyone have (or can anyone propose) a good workflow to convert a raw 1080p/30-frame H.264 clip such as this to Apple ProRes at 24p with as little quality loss as possible? Extra Credit: If anyone proposes using Nattress plugins, is it possible to post the above raw clip after conversion with those plugins so we can see what the results actually are? I'm almost sold on this camera but I've got to be able to get to 24p. And blast you Canon for leaving 24p off the feature list! Thanks. |

My plugins were never designed to do 30p to 24p. However, they do do 25p to 60i rather nicely... (not that it's much use here). I did work on a solution for getting very nice 24p, but it does cost $17,500...

The Big Red Loss
Quote:
Like most here, however, coveteth though I may a Red One, that $17,500 nut remains too tough to crack right now. By the way, tell Jim it's nearly 2009 and we're still sans all we ever asked Red for: A 24p HD camera with an interchangeable lens system that we could buy for what this ludicrous 5D Mark II headache is going to cost. At this point my assumption is that there is a law against providing such a device for sale to indie filmmakers. |

Thanks Dan and Chris and Jenn.
Looked good to me, especially considering the back lighting. I would like to see what a higher sharpness setting looks like. Do we have any aperture tricks yet, besides using non-Canon lenses?. I find lack of aperture control bizarre. |

Just for a hoot, I attempted following:
I have Cineform NeoHDV, so I took the file, and attempted to convert it to Cineform using HDLink. It did not kill HDLink, but I never got a file out of it. I then opened Vegas, put the clip on a time line, then rendered it to Cineform HDV 60I. I got a good file. I then opened Cineform's HDLink, and attempted to convert the Cineform 60i to Cineforms 24p, using the pull down. HDLink crashed and I got that Vista message saying the program wasn't responding. I then decided to rendered the original clip directly to the Cineform 24p intermedieate, and I got a 24p file from it. Looks pretty good.

Not so much a conflict of interest, but that I've never seen a decent 30p to 25p or 24p conversion. I'm sure it can be done, but I've never seen it. 30 and 24/25 are so close to each other, that it leaves very little room to work the temporal interpolation / filtering / decimation. You can be sure though, if I knew a good way to do it, I'd be selling plugins to do it as fast as I can!

Unless Dan indicates otherwise, it's straight off the CF card. The original filename was MVI_0461.mov before I renamed it for upload. It's 39.07 megabit, 30fps, h264, 1920x1080, 44.1k audio. There aren't any re-compression artifacts, it looks great to me.

So there is an audio filter opportunity for you but yeah, I expect the effect will surely be somewhat strange. I make slow movies in any case, so I'm going to try this just to see what the effect is like. |

Thanks for the info. Agreed it looks spectacular. Now I really wish there /was/ audio so I could try the "slow to 24p and them time/pitch-shift the audio" trick and see what the result is like.

I assume this camera does not have an actual 24p setting, so something like DV Filmmaker will have to be used ??? I have taken 60i stuff from my FX1, and rendered to 24p in Cineform. You do lose some resolution, but end up with a 24p file to edit with. From what I can see of the file I just did, some frames are essentially blended as I step through frame by frame.
