Hi,

does the p3p support 1080p/120?  I can't seem to set that framerate with the pilot app on android v1.2 (firmware 1.26).  max appears to be 1080/60.  

I'm trying to do some super slow-mo

thanks

looks like no 720/120 either:

It's no surprise that the P3A or P don't shoot at 120 fps. Ang Lee's latest movie is the first to use this high speed format commercially, so it's pretty cutting edge, not to mention that a P3 couldn't lift a camera designed to record in this format. The highest you'll get out of a P3 camera is 60fps. But what you want to do is make sure that your shutter speed is 120. (or double whatever frame rate you choose to shoot at) Then, when you take it into post, and apply your slow motion effects, you'll get a much smoother result.

Ummm, the GoPro Hero 4 Black does 720p at 120fps. The Phantom 3 could lift the Hero 4 just fine.

The Hero4 Black does 720p240fps and 1080p120fps.

Has nothing to do with it, the 120fps are more for slow motion use. I think the P3 camera could do it because it has the hardware.

"Double the frame rate" for the shutter speed is the "rule of thumb" for slight motion blur video. Much faster frame rates will *still* work and the individual frames will provide good detail - in which case, the faster the shutter rate, the better the detail, up to a point (laws of diminishing returns, etc.).

Since you're less interested in motion blur and more focused (no pun intended) on producing something suitable for slowing down (i.e., creating slow motion), the faster shutter speed is more likely preferable.

That said, I'm not a professional photographer and I could be all wet. My main experience with slow motion has been with my Hero 4 Silver GoPro. I shot some stuff at 1080p 60 fps and slowed it down. It really looked neat. So then I tried some more, shooting in 720p at 120 fps, then slowed that down - it actually looked too slow! I'm of the opinion that I slowed it down way too much. Something reasonable might be to process the 120 fps video to no slower than 30 fps - a 1/4 slow motion seems pretty vivid.

Someone who's more of an expert at slo-mo should feel free to set me straight.

Okay, boy did I get spanked!
All the previous posters were correct in what they've said. If you want to shoot 120fps with your Phantom 3 it IS possible. The camera itself has the capability, but the hardware/software that gets the image to your MSD card isn't up to the task. I've heard a lot of P3 users who would love to see the transfer bus speed increased to it's potential. So DJI might eventually provide it. Seems they have other more pressing issues right now.
My original comment was based on heavier cameras used in the film industry, but the Hero black looks like an excellent option. As pointed out, it's light enough for the P3 to lift, and certainly seems to  have the capacity to do outstanding high framerate video. Be prepared to spend some serious money on getting it, finding and installing a compatible gimbal, and getting it to work remotely from long distances without being able to use your P3 controller and Pilot app to do so.
aburkefl was correct in his evaluation of framerate/shutter speed. It's all about what looks good to YOU (and of course your client...if you have one). It also depends on how much post-work you do and what software you use to do it with. When you use double the frame rate for your shutter speed you create a ratio of 1 to 1. For example in a 1080p/60 situation, using a shutter speed of 120, you'd get 1 full frame of video every 1/60th of a second. I use Adobe After Effects, and this ratio, when combined with frame interpolation allows for a much smoother and cleaner slow motion footage as the inter-frame differences are more consistent. It's also easier to incorporate it into a 24p timeline if you're going for that look. So because of this, and other factors in my workflow, I tend to stay as close to the rule of thumb as I can. Assess your situation, find what works best, and stick with it (until something better comes along).
Tomtnt, hope you find a workaround to getting the exact look you want in your super slo mo footage

I don't know, I just find it hard to believe that the hardware isn't up to the task. At least, I don't think the bottleneck is bus speed. It's recording images at 60mbps which is the exact same as the Hero 4 Black.

Ahhh, yeah that's right. I rarely leave 4k or 2.7k so I forgot that the last firmware update bumped 720p up to 240fps. Thanks for the reminder!

I wish...I could imagine the Inspire 2 will come with a 1080p 120fps, maybe even for 4k, depending on how far away in time it is to release!

stevelucky;
I checked the thread that inspired my original comment about hardware/software issues, and these guys are way beyond what I can understand fully. So here's a link to the thread if you're interested.  It's on the phantompilots forum. Maybe you'll understand it better than I:
