Barry Green Hack - 2 frames per sec??
on Jul 24, 2008 at 6:08:27 pm

Hello HVX Users,

I was checking the Cinevate website (re: the Brevis).
I found this link to an interesting video:

http://www.cinevate.com/forum/viewtopic.php?f=2&t=2388#p16392

The videographer/photographer who posted this outstanding footage, mentioned that he use the "hack" mentioned in the subject line above.

How might I set my HVX200 for this? The quote from the cinvate forum page follows:
1. Time lapse that was shot by the HVX200 using a 2 frame/sec hack taught by Barry Green, author of the HVX Book and host of the HVX BootCamp DVD set that you can buy from here: http://dvxuser.com/articles/hvxdvd/

I do not have my HVX manual in front of me, would I be correct in stating that I would set the interval function for 1 sec, and set the frame rate to 2 to use this in my shooting?

Thanks,

Eric

Here's a copy of Barry's post to DVXUSER.
See the whole thread Here:
http://www.dvxuser.com/V6/showthread.php?t=53032

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 PRIVATEMEIGROUPPAVCNSBGP2SD 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.

Hello Kirk,

Whoa! and I thought it was a simple button push!
Amazing. I will have to give this a shot. Thanks for the detailed info on how to do this. I have barry's dvds, etc and have not yet watched all of them. so this will help!

Eric

Anybody know if there is a similar hack for the 2000 or the 500?
