SOME MORE FOOTAGE 720 60p

[Jarred Land]

Hey Barry dug up some more of the ninja shoot for us.. this time 720 60p footage (slow motion)

Thanks Barry.

mirrors feel free to update.

A little stoppage at the beginning but the rest of it looks very good. Nice slo-mo.

is it slowed down to 24p?

Wow does that look hot! Thanks Jarred & Barry.

I Love it! They have a picture of 'Tosh' up on the site.

is it slowed down to 24p?
Well, no, and yes.

It was shot using 720/24pN mode, which establishes a 24p timebase to the clips. But the actual frame rate was set at 60p. So it shoots 60fps and instructs the camera and editing software that the proper rate to play the clip at is 24p.

So it's not that it was slowed down in post or anything, because it's playing back at the rate we told it to base itself on. But it is being slowed down, because 60 frames are being played back at a 24-frame rate. It plays like that in the camera too -- you can see the slow-mo effect (or fast-mo, we shot 12fps too) right in the camera when you play it from the P2 card.

Hope that made sense...

WOW,
That's really cool barry.
I had no idea that cam could do that.
I figured we'd just have to shoot at 60fps and slow it down in post.
Very cool.

So even though the camera is set to 60fps, when it's encoded to the P2 card is it recording only 24 frames every second thus increasing recording time on the card?
Or is it sucking up the space using 60 full frames?

When in NATIVE mode (720/24pN or 720/30pN) it writes as many frames to the card as you tell it to. So if you're shooting 720/24pN and undercranking at 12fps, it'll only write 12 frames to the card every second. If you're overcranking at 60fps, it'll write 60 frames to the card. How those frames get played back is determined by which timebase you chose to shoot at. For example, shooting 720/24pN at 12fps results in motion that's twice as fast as realtime. Shooting 720/30pN at 12fps results in motion that's 2.5x as fast as realtime.

12p's kind of cool -- even a 4gb card will show that you've got 20 minutes available recording time! :thumbsup:

now that is pretty darn interesting...

[Justin_Kirch]

so, in reality, if you duplicate those 12 recorded frames you will get full 24p motion?

[zanoonga]

is the shutter 1/48 or 1/120?
It feels a little motionblurry... otherwise, nice slomo-speed!

[Antoine_Fabi]

Barry,

So,,,
if i understand correctly, the only limitation with this method is that we can't use normal 1/48 shutter speed (in 60fps) ?

Barry, Jared, ProjX,
Can you guys PLEASE, post stuff in H.264, the WMV files DO NOT PLAY ON MACS correctly!

Thank you.

[Jay Rodriguez]

Is it just me or does it look a bit choppy?

[Jaime Valles]

The slo-mo looks incredible!!! Damn, I wish this thing had come out 3 years ago...

[NO CA$H]

Looks good in slow motion.

Who is this Kung Fu guy?

[mikkowilson]

oh boy am I running slow today... Meh, it's finals week, I shouldn't be here 24/7 anyway..

File is now also mirrored as normal here: http://mikko.n3.net/hvx200

[fiercecurry]

Slo-Mo footage in H.264 please. Not everyone uses PC's.
thanks

[Luis Caffesse]

Thank for the Mirror Mikko (or should I say the "Mikko Mirror")
You rock!



damn i make bad jokes
:)

[mikkowilson]

yes, that was a horrible joke. Infact I'm not even going to begin to reflect on how bad it was.

[Luis Caffesse]

nice.

..your jokes may be bad, but my puns are verse.

[Luis Caffesse]

that actually made me laugh out loud.

alright, this has gone on long enough... you're Finish.
(yes I know, the appropriate term is Finn.. but Finn just wasn't funny).

...i got nuttin. (but I'm curently watching the end of '2001', so I'm aloud to be a little out of it)

[Jaime Valles]

We can see right through your puns. :happy:

[taubkin]

Awesome.

This footage really doesn't work well in macs. Luckly I have Flip4Mac and manage to export DVCProHD footage (.movs) from those H264s and WMVs. It's incredible how DVCPro HD runs so smooth on my Mac. It's really not that new.

[speedbump]

Well, that pretty much clinches it for me in terms of my next camera purchase. The 60P footage is everything I could have hoped for. Thanks Jarred and Barry for making it happen, and making it available to us.

The variable frame rate, data density, and color space of this $6K camera are simply amazing. My girlfriend is going to get really tired of me whining about it until I buy one.

[Barry_Green]

so, in reality, if you duplicate those 12 recorded frames you will get full 24p motion?
No, you'd have step-printing 24fps. It would play at 24fps, but only 12 frames would be updated. So that's probably not what you want...

[Barry_Green]

is the shutter 1/48 or 1/120?
It feels a little motionblurry... otherwise, nice slomo-speed!
I'll have to see if there's any way to verify. This was the very first time we had shot slow-mo. Ideally it should have been on 180 degrees shutter, which would make for 1/120 shutter speed. I'm not 110% sure that it was though. Should have been...

[Barry_Green]

Barry,

So,,,
if i understand correctly, the only limitation with this method is that we can't use normal 1/48 shutter speed (in 60fps) ?
You wouldn't want to anyway -- if shooting film-style slow-mo, you'd want to use 1/120 (the shutter speed you'd get with a 180-degree shutter at 60fps).

But if you want to use a longer shutter, the longest shutter speed you could get would be 350 degrees, or approximately 1/58 of a second. At slower speeds you could get 1/48; the fastest frame rate you could shoot 1/48 would be 48fps.

[Barry_Green]

Looks good in slow motion.

Who is this Kung Fu guy?
www.jakebass.com (http://www.jakebass.com). Superb stuntman, and he was playing the role of Batman at some stage show back east.

[theos]

nice footage, the only thing I am not getting is why is the footage I am seeing 720 . . . I mean 720 high? I may be missing something but isnt 720 the width of the image as in sd? even the 1080 footage I was looking at is 1080 high by a 1920 wide. I must be doing something wrong :(

[harlan]

In HD 720, 720 is the height. 1280 is the width. Together they make 1280x720.

The same goes for 1080. 1080 is the height, and 1920 is the width. 1920x1080.

Hope that helps.

[theos]

thanks harlan, I founds this that further explains what you said http://www.sony.it/content/attachment/S1B3%20Link%20-%20Resolution%20Chart,1.jpg . . . so I am now aware that the hvx is the one offering 2k plates over 1080i :)

[harlan]

anytime.

Oh...i forgot the equivalence for shutter angle...
makes a lot of sense.

thanks

BTW, the slow motion clip looks very natural...impressive.

[braw]

It plays like that in the camera too -- you can see the slow-mo effect (or fast-mo, we shot 12fps too) right in the camera when you play it from the P2 card.

Excellent!! That's exactly how I hoped it would deal with the variable frame rates.

[Justin_Kirch]

Is it just me, or does the clip stop for anyone else 2 seconds into it?

[Luis Caffesse]

My clip has a small glitch 2 seconds into it, but it plays right past it and goes on for another 28 seconds (30 seconds for the total clip)

What's your file size Justin?
The file I have is 30.1MB

[Justin_Kirch]

it was 30.1....i actually saw the whole thing. i read another post where it said firefox doesn't like h.264, which is weird, because i swear i've watched videos with firefox before.

i opened up IE and it worked, still had that 2 second glitch, but i saw the rest. thanks for the help Luis.

[reticulan5]

I would love it if all HVX200s could shoot 24 and 60 fps.Here in Australia we are limited to a 50 fps.
Hopefully the next model may remedy this.Universal P2s yeah!
