Slowing Water Flow

Well-known member
I'm looking for a way to slow down water using HVX200 720 24pn in the film cam mode if possible.

With a 35mm camera we used to do a longer exposure which would create what we called the angle hair water effect. Can this be done with the HVX any help would be appreciated.

:dankk2: Thanks in advance

Slow motion? Or smoothing out the water flow?

For slow motion, change the "frame rate" parameter up to 36 or 48 or 60.

For smoothing out the flow of water you can change the syncro scan to 350.0d, then change your shutter speed so it says 350.0d.
 
Thanks for the reply Berry, will give it a try, I'm shooting fast moving water and want to add a smoothing out look to the flow. Will post results.

Again Thanks

if i am interpreting your "angel hair" term correctly, simply dropping the shutter speed to 24 MAY get you there.?.?.?...
 
I'm pretty sure you're talking about:

As has been described, opening up your shutter and/or slowing your frame rate can create this effect on the HVX.

Unfortunately, you can't do (without compositing) the slick syncro flash effect which allows the foreground to be crisp while the background water is smooth. Also, you'll be restricted to locked down shots with little other motion in the scene or else the entire shot will become "blurry."
 
MarkS22,

You got the right effect in the link, I shoot a lot of nature and discovery is showing waterfalls like in the link so I want to give it a try.

I am in Film Cam I shoot at 720 24pn and take the syncro scan to 350.0d,
then change your shutter speed so it says 350.0d.

No moving bodies just water if this is right I am ready to try.

Thanks for the responce

If there is no camera movement you could post another layer or two with opacity above your original Video layer. (Screen effect may help). Delay the top layers a frame or two out of synch in the timeline.
 
I've never really tried to get the angel hair look with the HVX yet but I used to do it all the time with my 35mm camera as well.

Usually, I'd try to leave my shutter open for at least 1/4 second if not longer.

Although I haven't tried it, what I would probably do is to use the 2fps hack with the shutter set to 350.0d and then slow the footage back down in post.

That should give you like 1/2 second exposure I think which would be enough.

But, like I said, I've never tried it so I don't know if it would work or not, but I think it would be the best you could do with the HVX.
 
RE1000,

720 24pn

Film Cam
60 Frame
180.0d

The clip on the web after looking at it is when I got the idea to slow the water even more I think it will pop the clip, also the Heron then started to climb the falls and I got it all on film wings spread and him climbing up a water fall.

I hope the info helps,

n8ture,

I understand the 350.0d but the 2fps hack? Need a little help on that one.


Thanks

Barry Green, explained the procedure the best. His explanation is below. The thing to remember is when you play the hack back at 24fps, everything is speeded up so you'd have to slow it down in post to look "normal"

Here's the procedure:

1) Get a scene file text file on an SD card, usually by going into menu 8, CARD FUNCTIONS, and saving scene files to your SD card.

2) Open the scene file text file in the PRIVATE\MEIGROUP\PAVCN\SBG\P2SD directory, called SCENE1.TXT (or scene2.txt, scene3.txt, or scene4.txt) using a text editor like Windows Notepad

3) Look for the next-to-last item in the scene file. Here's what a sample scene file text file looks like:
00005000: 8 ; DETAIL LEVEL: 0
00005001: 8 ; V DETAIL LEVEL: 0
00005002: 8 ; DETAIL CORING : 0
00005003: 8 ; CHROMA LEVEL: 0
00005004: 8 ; CHROMA PHASE: 0
00005005: 8 ; COLOR TEMP: 0
00005006: 16 ; MASTER PED: 0
00005007: 8 ; A.IRIS LEVEL: 0
00005008: 1 ; NEWS GAMMA: OFF
00005009: 0 ; GAMMA : HD NORM
0000500A: 0 ; KNEE: AUTO
0000500B: 0 ; MATRIX: NORM
0000500C: 1 ; SKIN TONE DTL : OFF
0000500D: 0 ; V DETAIL FREQ : THIN
0000500E: 0 ; OPERATION TYPE: VIDEO CAM
0000500F: 0 ; FRAME RATE: DEFAULT
00005010: BE026801 ; SYNCRO SCAN :

That next-to-last item is:
0000500F: 0 ; FRAME RATE: DEFAULT

You can ignore everything after the semicolon; the semicolon indicates that it's a "comment" and will have no bearing on anything else (so, in this example, the part that says "; FRAME RATE: DEFAULT " is useless, it affects nothing, it's just there for human-readable description).

So the relevant part is:
0000500F: 0

The only thing you would want to change is that last number (in this case, "0"). To get different frame rates, use one of the following numbers:

0 = DEFAULT
1 = 2fps
2 = 3fps
3 =4fps
4 = 6fps
5 = 8fps
6 = 10fps
7 = 12fps
8 = 14fps
9 = 16fps
10 = 18fps
11 = 20fps
12 = 22fps
13 = 23fps
14 = 24fps
16 = 26fps
17 = 27fps
18 = 28fps
19 = 30fps
20 = 32fps
21 = 34fps
22 = 36fps
23 = 38fps
24 = 40fps
25 = 42fps
26 = 44fps
27 = 46fps
28 = 48fps
29 = 50fps
30 = 52fps
32 = 54fps
33 = 56fps
34 = 58fps
35 = 60fps
36+ = repeat of sequence from 50fps to 60fps

So, for example, if you wanted to get a frame rate of 2 FPS, your modified line would look like this:
0000500F: 1 ; FRAME RATE: DEFAULT

And if you wanted 44 fps, it would look like this:
0000500F: 26 ; FRAME RATE: DEFAULT

(don't try higher than 35; I tried 36 and it set it to 50fps, 37 set it to 52, so I think it just repeats 50-60 for all fields set higher than 36)

4) Save your modified text file back onto your SD card

5) Put the SD card back in the camera, go to CARD FUNCTIONS, and read the scene files into the camera.

Now, when you go to the appropriate scene file, you'll see the new frame rate there. But be aware, the only way to assign these "nonstandard" frame rates is through the SD card. If you use the menu to try to change the frame rate, you'll lose it -- it'll immediately jump to 60, and then only allow the normal rates to be selected. You'd have to re-load the scene file from the SD card in order to re-establish your "nonstandard" frame rate.
