Slow motion

Hello, here are examples of slow motion shots I wanted to share with you.
http://vimeo.com/34202545

these are shots from a not yet edited music video I shot 2 weeks ago in slow motion.Sharpness is difficult to tell since the director wanted extrem shallow depth and the sharpness was down to 0.

Not color corrected in the first part but I did my own color profiles on the camera based on abelcine profiles.
The second part are the same shots but quickly corrected on "Magic bullet looks" just to see how it reacts.

Shot in S&Q mode
shutter speed at 25 or 50
Feets and running were shot with Nikon 105 dc F/2
the rest with Takumar 50mm 1,4
The two lenses of mine I love most.


The night shots were in deep forest with just a 550W led light 8meters over their heads. The last night shot had a 2K light 20meters away on their left, a 650w fresnel 8meters away on the right and a candle light.

Looks good. Some great shots. Especially like the shot of the boy in a wider shot amongst the mist.

I wish the director wasn't on the "make it shallow!" bandwagon. When the kid lifts up his mask it's one very nice out of focus shot... No offence I just hate the overuse of extremely shallow depth of field.

I prefer the shots before magic bullets but then I seem to be one of the few people that likes shots kept pretty flat.

Look forward to seeing the finished video.
 
Thanks, I totally agree with you ;)

I'm also looking for some opinions on slow motion because this shooting brought me some technical questions.
The S&Q mode seems much better and smoother than shooting in 60 or 50fps and slow it down by 50% on my timeline.
Some shots that I recorded on a ninja atomos and slowed down with Twixtor were very good, others I got some really bad effects around the moving subject (but I don't know twixtor that much).

I'm looking for some opinions as quality wise: which is the best? the use of an external recorder and then twixtor or just S&Q mode on SD card?
To me at the time of this shooting the safest was to use the S&Q mode.

I don't now why but I also found that slowing down by 50% on my timeline a S&Q mode shot, I get a better smoothness than converting a 50fps shot to 25fps. (I therefore get in S&Q mode a smoother 2 times longeur shot than a 50fps to 25fps shot).
 
If your NLE does it right, there shouldn't be a difference in quality with slowing down 50 or 60 fps vs. using S&Q, but FCP7 for example doesn't do it right. Use Cinema Tools for slowing it down instead.
IMHO Twixtor is the best tool for artificial slo-mo out there, but all of them are very scene-dependent. Sometimes it works, sometimes not. But it works much better if you have more fps from the start and avoid motion blur in your original footage, so just use it for more extreme slo-mo – nothing beats true fps. If you need motion blur in the end, you can add it with RSMB (from the same company).

Yes, at the time of the shooting the question was to either go for the quality of the slow motion of the S&Q mode in 24mbs or the image quality with a proress external recorder and use twixtor.
Even though twixtor is a great tool it sometimes doesn't work. We therefore preferred to go for the much more compressed but safer slow motion of the S&Q mode.
The video is intended to be broadcasted and the quality on the image of the S&Q mode seems to me to be very decent.

I've read somewhere that since it doubles the time you actually shoot at 48mbs then dobled in time by the processor it becomes a 24mbs. I don't know if that is relevant or true (probably since at the end you get 24mbs files).

In S&Q mode, the camera processes 60Mbps in real time but the recorded file is 24Mbps. I know Twixtor can do a great job most of the times but it can never beat real frames. Plus, you can slow down S&Q footage even more down to 120fps with very good result.

Great looking shots, BTW.
