Question about editing

Alright so I have a HV20 which produces 1080i video. But Facebook can't support 1080i, not even 1080p. So I have been rendering in 720-30p 29fps. Are there any immediate drawbacks to this? I know that the resolution will obviously be changed I have rendered video and it looks alright on you tube and Facebook but now I'm wondering if there is a better way to go around this.

PS I'm also interested in different filming for the HV20 because I know there is 60i, 30p and 24p, whats the difference?

thanks

I don't own an HV20, but I'm looking into buying an HV40 and from what I understand:

60i: good for slow-mo clips, kinda has a news-broadcast look to it, and it's interlaced (I think there are some drawbacks to this but i'm not exactly sure what they are haha)

30p: kinda a good all-around framerate, gives you a home-video look, decent for slow-mo, no pull-down removal required so it's easier to edit, and I believe it's good for most skiing

24p: gives you a cinematic film look, hardest of the 3 to get smooth slow-mo, on an HV20 you have to remove pull-down to get true 24p video, and it's the hardest of the 3 to film skiing with because you have less frames to work with so you gotta be smooth or else your video will come out looking like crap.


This is just from what I've gathered from reading various forums and stuff though, so people who actually know what they're talking about will prolly give you better insight.

pssst.
just so you know
technically, 30p is a higher frame rate than 60i. because 60i= 29.97 frames interlaced. So why not shoot 30p?

So I should be shooting 30p? how do I set my HV20 to film on that?

I'm not sure the HV20 has 30p... So in that case I would just shoot 60i which is the standard HDV mode.


To the other guy: 30p doesn't technically have more frames than 60i... They have the same amount of frames, just 30p is 30 full frames, whereas 60i has 60 half frames.

half frames as is one on top of the other?

I don't understand progressive VS. interlaced at all

as in one of the half frames (which is called a field) has all the odd horizontal lines while the other one has all the even ones. One field would show for 1/60th of a second, and then the other would show for the next 1/60th of a second, and that would make up one full frame. So basically at any given time you're only looking at 1 field (one half frame) but it's so fast that our eyes interpret the 2 seperate fields as 1 full frame.

Here's what you do:

For normal speed, shoot 24p with the shutter at 1/48. Conform to 23.98 in CinemaTools to make it progressive (miniDV technically can't shoot true progressive).

For subtle 16mm-esque slow motion, shoot 30p with the shutter at 1/120. Conform to 23.98fps in CinemaTools to get progressive slow motion.

Import and edit your newly conformed footage into a 23.98fps timeline.

Avoid 60i. Just don't use it. Unless you are filming a soap opera.

I only use 60i when I know I'm going to want SUPER slow mo. Thats 1 out of 40 shots for me. I used to do all 60i but I grew out of that, thank god.

With my camera, I have settings so that I can edit 24p and 60i in the same timeline. I do that.

For you, do what Landis said. The 1/48 shutter is a standard rule of thumb for videographers: 1/(2 x frame rate). 24p is your ideal frame rate because its that of film. Like Landis said, if you want slow mo you can film it in 30p and then, in a 24p timeline, slow it down 80 percent, because 30 x .8 = 24! WORD!

Good luck homie, and just mess around with your camera to get that you like.

Hmm I never knew that, thanks for sharing! I always had the idea that 24p was too slow of a framerate to capture skiing smoothly, but I guess I was wrong. +K

It is if you aren't experienced keeping your pans perfectly in sync with the motion of your subject. 24p takes a lot of practice, but well-filmed 24p shots are essential if you don't want your videos to be 100% slow motion like half the ski edits on NS...

Hmm just a quick thread jack: what are the advantages to 24p compared to 30p?

Oh whoops sorry - um I'm pretty sure you can't work around it if it doesn't support 1080p, so I would think that your workaround is about the best you could go at it. And I don't really see any other drawbacks other than the fact that if you want to put it in full quality on another site such as Vimeo or Youtube, you'll obviously want to keep your original footage and your project file.

24p is the "standard" framerate for normal speed. true 30p is technically slow motion. The reason I say "true" is because miniDV cameras can only record in 60i, so it only shoots pseudo-progressive modes with advanced pulldown. A lot of aerial footage from Planet Earth is shot at 24p 1/120, but you wouldn't know at first glance because it is SMOOTH. Smooth movement can make or break a 24p shot.

And to answer your question, here are some compression settings:
