Canon c300, 24Psf?
Posted 28 February 2012 - 11:09 PM
So my questions are....
1. Am I definitely correct that the Canon c300 can not output a 24Psf signal from the HDSDI?
2. Is that something that can be added with a firmware update?
3. Is there an external accessory that can convert 60i to 24Psf? I have found a few frame rate converters online but they are all north 10,000$
I spent a good amount of time on the phone with Canon Tech Support and actually couldn't get solid yes or no answers on any of these questons.

B&H Photo and Video's YouTube channel has a 44-minute video introducing the C300 and this is where I heard this.
Sorry. On mobile, otherwise I would post direct link.

Good to know. Thanks!
Yes, it's 60i only but as mentioned it does flag duplicate frames. All recorders I've tried, even the cheap Samurai can properly flag and remove pulldown from the signal.

For max compatibility, shoot ALL the cams as 23.98p over a 60i carrier and even the first generation of live switcher will handle it beautifully. The final signal will work fine for all televisions, and if the set is decent, it'll recognize the pulldown flags and "reverse telecine" in the final TV, showing a true 24p picture - even though the project itself was shot, switched and broadcast on a 60i signal. Psf......I don't believe that a PsF signal can even be legally broadcast in the US, it requires post-conversion (perhaps internal to the switcher) to be a broadcast legal 60i signal....and at that point - why not just shoot ALL the cams at 60i carrier to begin with and integrate your shiny new C300?????
Sounds like some tech director fed them bad info about how psf is more "real" 24p than simple 23.98 over 60i.... again - either way you're shooting 24 fps.
