HVX 200 Frame Rate Hack and Time Lapse

It's really awesome when you buy a piece of gear and though it provides the value you purchased it for, you discover a hidden feature or a new way to use it that you hadn't considered. Like anyone else with eyeballs, I enjoy time adjusted footage whether it be true slow motion or awesome time lapse. I haven't really gotten into actually creating it because the equipment is pretty specialized and often expensive. It's hard to justify buying specialized gear unless you are going to see some kind of return on it, so buying intervalometers or high speed cameras has never been a priority for me. Enter the continually awesome HVX 200.

Awesome HVX Time Lapse Demo

While it's starting to get a little old and the camera has some quirks, it continues to impress me with it's flexibility and wide range of features designed for a director of photography with high standards. Even features that were never meant to be found are hidden in the murky depths of settings files and menus. With a little work you can get great results from time lapse and slow motion. It even offers a high degree of control over the rate of the motion change. This topic has been covered in a lot of places, but I'm going to rewrite the tutorial here because there simply isn't enough detail on the exact specifics in other locations. I had to piece several tutorials together and get forum advice, but allow me to save you that hassle.

Hit the jump for the whole story.

What you need

Well, I mentioned the HVX, now you'll need to note that this is a P2 format, so you won't be able to use tape. P2 card is the way to go. While I've read that firestore hard drive solutions seem to work in some setups, we won't be going over that.

You'll also need an SD card, the regular kind and some kind of reader for your computer (mac or pc, even pda).

We will be editing text files, so a good text file editor is needed. I'll be using notepad in windows.

Shooting time lapse is great when the camera is stable or in a moving stabilized setup. In cars, it's fun because it shows the travel from point A to B in high speed, while setting it up in a crowd on a tripod is fun because you see all those people zooming around. The huge advantage of setting the shutter to a slow speed though is that the low light photography looks great. Motion gets a little blurry but in time lapse land that ends up being pretty great. Try testing at night on a city street as well!

any idea how to make a shutter speed about 1/6 or 1/8? this tutorials on 350d was great by the way, thanks for sharing.

It seems as though the hack really only applies to the 350d shutter. As the other shutter speeds are locked to fractions of a second. If you did the math, you can set the shutter to any number of values of degrees. IE: at 2 FPS and 180 degrees, you get 1/4 second. If you keep adjusting the number and frame rate, you can find your desired shutter, though it won't work at a normal video framerate too well (30 or 29.94)

I have been trying to figure it out and this tutorial has got me along to seeing the light, but now that i got the frame rate hack to work i can't shoot a timelaspe. I feel like I have tried everything and gave up for awhile but now I back to trying. I cannot access interval recording in film cam, but the hack has never worked in video cam.. any suggestions for a lost soul?? Anything will help.

You are right, Interval does not work in film cam, but this hack and accompanied technique does not use interval shooting. We are using the frame rate to handle that for us. Instead of shooting one frame every half second, we are shooting two frames per second. when you shoot it will look stuttery on the camera viewfinder. Put it on a 30P timeline to see what it looks like played back at full speed. Don't try to use video camera, or your shutter will go back to fractions of a second, preventing that nice low light response and very pretty streaking of moving lights (car headlights, etc) during your footage.

I set up the hack on my hvx200 and recorded to the firestore but when I injested into fcp pro and played it back it was very choppy. did you change the speed in post to get the fluid motion?

Two things come to mind, Martin, one is that firestore is fudging the framerate or you may want to try a different setup in FCP it should be 720P 30fps. When it plays back it should be nice and smooth. Does it playback as timelapse on the camera? Do you have a P2 to try?
