Can't decide between 1080p/30 and 720p/60

    Which is better for video? I've read some claims that 720p/60 is the best, and there are even less artifacts. Also, someone mentioned that the bitrate is only around 12 Mbps, which hinders the quality of 1080p filming.

    Well the 720p is double the frame rate of the 1080p
    That quite often leans towards them being quite similar in terms of overall size of the file created.
    1080 would be better BUT the 720 has double the frame rate which is also worth bearing in mind.
    I use 1080/50 on my Gopro and there is a big difference between that and 1080/25
    The 25fps seems quite jerky at times whereas the 50fps is much smoother.
    Depending on what you want to do with the footage afterwards will effect your choice.

    Cool, so 720p and 1080p are really the only two options worth using?

    I disagree 30fps or 60fps whatever the resolution are equal in detail and sharpness, provided that they both have their shutter settings at 180 degrees, that would be 1/50th (Ideally1/60th), and 1/100th, (ideally 1/120th).
    If 30fps and 60fps were to use the same shutter speed of 1/50th, then yes, 60fps would probably show some motion blur and give a less sharp image than the 30 fps.

    So if you want to fly a mission with Ground Station and record the path, it is better 720p/60 ?

    60 will give you more smoothness, but to get full advantage of it you should watch your shutter speed as well. Is it something that you can do on your camera?
    All depend on what you are going to do with it. 720/60 is perfectly acceptable as well as 1080/30. personally I tend to shoot at a higher frame rates.(1080/60)
    (actually at 1080/50 since I am in the uk but you got the picture)

    I don't have much control over shutter speed with the Vision 2+ camera, do I? I sometimes change ISO, but to be honest, even 100 isn't so great. 2oo looks noisy, and it get worse from there.

    Here's three quick examples. First off, these look way better on my PC. The pans on YouTube look extremely choppy. Why do they looks so bad?

    1080p/30

    1080p/24
    https://www.youtube.com/watch?v=aaL910x6qbY


    720p/60
    https://www.youtube.com/watch?v=8sHrMDjogvo

    Watching the 3 clips on my PC, I like the 1080p/30 the best. The 24 fps is too blurry and choppy. The 720p/60 is so smooth that it looks artificial. The smoothness when panning seems to accentuate the fish-eye effect of the lens. Looks weird, IMO.

    I downloaded and watched all of them, I agree the 1080/30 is the best one. 24 is choppy as a 24. The less frames you have per second, the more choppy, specially in the pans. 1080/30 is quite the standard anyway. you probably should stick to it.

    What about shooting in 1080 60 FPS and then slowing it to 1080 30 FPS? I really like how it looks.

    The Vision + camera cannot capture 1080 60 FPS (frames per second) footage.

    It is limited to 1080i/60 which is 60 interlaced fields per second (it takes two interlaced fields to make a frame). This is roughly equivalent to 1080p/30 footage.

    Wow! I never said that 720 was sharper than 1080! This is the whole purpose of the high definition!
    I said that whatever 30 or 60fps, this is not this that makes a picture sharper or not.

    If I had to choose between 1080p/30 and 720p/60 I would go with 720p/60. But on the Vision Plus there is another choice -- 1080i/60. I know that it is interlaced. I know that it is not truly 60 fps. But in my experience it is way better than 1080p on the Phantom and comparable to 720p/60 but then I have to up the frame size to match the rest of my video. I have found 1080i/60 to be the smoothest and overall best option for me.

    I agree with you, 1080/60i is the smoothest you can get but only if you make a Blu-Ray. (or if you shoot for TVnews) However, if you intend to publish it on youtube, you will have to de-interlace when you export, which sometimes creates some aliasing problems...

    The difference in quality between 1920 and 720 is not that discernible on the internet. Whether when projected in a hall there is a big difference it is possible. A quick demo all taken within minutes of each other. http://vimeo.com/109468181

    When you view it on a large screen the difference is more obvious. (I use a 40" as computer screen). The compression seems very high on these clips anyway. is it a V+ camera?

    1080i60 has been my favorite so far, but I find youtube lowers the FPS, so if I plan on uploading it I go 1080p30

    Yes it is a standard v+ I will check it in a hall with a projector using less compression sometime
