Posted via email from Zach’s posterous

I was a first-time visitor to Hawaii recently, and shot a lot of photos and video. I’ll be dribbling it to my blog in bits and pieces as I go through the footage. Here’s a taste: a green sea turtle at Ho’okena Beach in Kona, Hawaii. This turtle popped up as I was snorkeling in deeper waters and swam alongside me all the way back in to shore. A beauty. Perhaps she was amazed to see a film/video editor out in direct sunlight?

Meandering tech notes:
Shot with a Creative Vado HD solid state 720p camcorder (1st generation)¹, in a Creative-branded Aquapac underwater housing.

The Vado HD is very similar to the Flip Mino HD and the Kodak zi8; I like it because it features a much wider-angle lens than its competitors. The Aquapac is basically a $30 very clear plastic bag with a watertight seal. Though this one’s branded for the Creative Vado HD, it’s probably large enough to fit two of them side-by-side². One one of my snorkeling adventures I brought along my Canon HV20 in a dive housing, and its remote control (to start and stop the camera’s recording) in the Aquapac alongside the Vado. I probably could have put my cell phone in there as well but didn’t trust the bag yet and honestly didn’t really want it along.

This turtle clip is from the 2nd day of my trip, before I’d figured out that if I squeezed out all the air in the Aquapac before sealing it, the plastic would remain taut over the lens, resulting in a sharper image. Less air in the bag also would have resulted in a tighter fit against the screen of the Vado HD, which would have given me a fighting chance of seeing the image on the Vado’s screen underwater –most of the footage I shot on the trip, including this turtle clip, was shot by blindly pointing the camera and hoping.

I snorkeled with the Vado in the Aquapac bag all week and had no problem with leaks. I was a little worried about this, but wasn’t risking much as the 1st and 2nd generation Vado HD go for $49 these days (B-stock of the 4Gb versions on Creative’s website as of 7/2010).

1. I’ve written up the Creative Vado HD previously here and here.
2. 3D anyone?

So I bought the device and have tested it out. When I plugged a cable between its headphone jack and my car’s audio input jack and streamed audio to it from my iPhone, it worked a treat. It shows up in the iPhone’s bluetooth menu as a device named,”BCK-08″.

There are a few problems. The device’s built-in battery is pathetic, and within an hour or two of use it begins to beep every few minutes to indicate that the battery needs a charge. I also think the audio quality decreases in direct proportion to the battery’s charge, but am not positive about that.

My goal is to take apart this device, wire it to be powered directly from my car, and leave it permanently connected to the car stereo’s auxiliary input jack.

I’ve found a few resources on the net that may be of help:

• The data sheet for the chip used in this device, the ISSC IS1621N. I wish this PDF file were available to simply download. To have to view it in a flash-based viewer feels archaic, and overprotective for information the manufacturer should want to widely disseminate. I do see a button labeled “download” (in Chinese), but to download requires an account on the website and I don’t feel like jumping through account creation hoops in Chinese right now³.
• A page about the chip at its manufacturer’s website.
• The page of someone who has already taken apart the BCK-08 and is planning to do a similar project. He mentions a desire to get line-level output from the device. I think that’d be nice, though I notice no mention of a line out in the chip’s pinout, only an amplified headphone out.
• Wikipedia’s writeup of the LM317 adjustable voltage regulator, which is probably the part I’ll need to use to take my car’s 12V as input and supply 3.7V DC to the BCK-08.
• Or perhaps I could use this constant current-regulated LED driver⁴ to bring my car’s 12V down to 3.7V. It’s designed for high-power Cree LEDs, which take 3.7V input, so I’d guess it might be about right. Would save me some time designing my own circuit with the LM317, and it only costs $2.39.

1. I’m sure many other cars also have this feature.
2. The device’s full name on DealExtreme’s site is “Bluetooth 2.0 A2DP AVRCP Stereo Music Receiver and Handsfree (Black)”
3. I’ve been out of China for 3 years now and don’t feel like spending an hour fighting my way through the website with a dictionary in hand
4. Also from DealExtreme –how about that?

I thought this screenshot might amuse. Click the photo to see it at full-size. At the top of the image are photos that include Chow Yun Fat, cropped to just the automatically recognized face. Below a line are photos that Aperture 3 thinks may be the same person. To refine the computer’s idea of what his face looks like and tag more photos with the appropriate name I had to select all Chow Yun Fat photos from the bottom part of the screen and drag them to the top, above the line.

For more info on the facial recognition feature in Aperture 3, check here on Apple’s website.

I have about 16,000 photos in my archive, and though the process isn’t completely automatic, the facial recognition feature made it much more feasible to tag all the people in these photos. Even just the fact that the application can display an entire set of photos cropped and resized to only show faces alone would be a huge help, the fact that Aperture 3 makes decent guesses is a bonus.

5/19/2010 4:43pm Edit: I’ve been told this feature was in the previous version of the app. I just never happened across it

The official iPhone Twitter client is finally up in the app store, today, now. The app,”Twitter”, is actually version 3 of what used to be called “Tweetie”. Twitter bought Tweetie, and what was previously an excellent commercial app is now free and improved.

The “Nearby” feature of Tweetie v2, which showed a list of nearby recent tweets, has been updated for v3. It’s more difficult to find this feature in the new version of the app, as it is accessed via an unlabeled button, but it’s there and has been significantly upgraded. Now one can see not just a list of nearby tweets, but tweets in any area, overlaid on a Google map.

On the one hand, I’m all about openness, and it seems pretty cool to be able to see what people in a given area are tweeting, overlaid on a map.

On the other hand, the ease with which any of us iPhone Twitter users¹ can now be tracked down by stalkers, paparazzi, their mothers, and other ne’er-do-wells is a little scary.

Change. Scary and neato, at the same time.

1. iPhone Twitter users who opt-in for the app’s location feature when asked, that is.

Below is a screenshot of my version of assignment #3 running on my iPhone. Every control on that screen works as expected, it’s pretty neat. Most importantly, I finally understand how and why.

You can find the lecture slide PDFs and other materials on Stanford’s website, and video of each of the class lectures are available as a free podcast in “iTunesU”.

I have the less-full-featured version of this watch, the Garmin 205. When I’m running regularly and am in good shape, I find this watch to be handy. I can look at it at any moment to see my current pace and make sure I’m not running too fast to go the distance and avoid injury. If I’m running a particularly interesting or novel route I’ll connect the watch to my computer and look at the path I’ve taken overlaid on an online map alongside an altitude/time/pace graph. It’s also handy for biking. The Garmin 305 builds on the features of the 205 and adds a heart-rate monitor (which is recorded along with the other data for later review on your computer) and the ability to communicate with wireless accessories (such as the Garmin GSC 10 Speed/Cadence Bike Sensor). I find running to be a much more enjoyable activity when it’s combined with data collection.

If you’re in the market for such a GPS watch now¹, I think this is a good buy at $125² .

1. and don’t feel like waiting a few years for the watch to get discontinued and show up at a local garage sale so that you can then buy it for 1/3 the price but live with reduced battery life due to the advanced age of its rechargeable battery pack
2. i just can’t bring myself to write “$124.99″ for some reason. $124.99 is effectively $125. Can someone explain to me the marketing benefit of ending all prices in $0.99?

Euphonix’s "MC Mix" hardware control surface. A nice piece of kit, costs $999. It’s a little smaller than the Mackie Universal Controller, a plus in my opinion.

Unfortunately, the motorized movement of these faders can also be noisy, especially the clacking sounds emitted as many faders pop into position at once. This can be distracting when trying to mix a quiet, emotional scene. These controllers are also pretty expensive, starting at about $1000.

Enter the iPad and Saitara Software’s “AC-7 Pro Control Surface”:

The control surface in the video looks very cool to me. It’s silent, can be seen in a dark editing room, appears to function as well as I’d need, and the cost of the app is only $9.99. I’ve played with a friend’s iPad, and know the touch-sensitivity of that screen is accurate and responsive enough that I’d have no problem adjusting several tracks at once with this interface. For those addicted to the feel of hardware faders this might not cut it¹, but for me it’d be a big improvement over moving the faders in Final Cut Pro’s “Audio Mixer” window with a mouse. I can’t justify spending $1200 on a set of faders I’d barely touch except a bit towards the end of a project, but $10² ? Hmm.

Yet another reason to consider an iPad. I wonder how long I’ll hold out? Sigh.

1. I don’t think this is just a matter of purely subjective preference –one can feel where a hardware fader’s control is in space, and there’s probably a bit of resistance built in so the user can feel when the level has been set at unity without having to look.
2. $510 if factoring in the cost of an iPad, which can also be used to access the iPoo social network.

I figured it’d be fun to keep an eye on this little competition. So I threw together the google spreadsheet embedded below. If² Apple’s market cap exceeds Microsoft’s, the phrase “Bill is still happy.” will change to something more Applelicious, and I’ll copy my former Apple coworker’s idea³ and throw a little party to celebrate the contribution of both companies to the US economy. I’ll use leftover party favors from the Windows 7 party I was selected to host last year and still feel guilty for not having thrown.⁴

I welcome any suggested changes or additions to the sheet. Enjoy.

1. Market Cap definition from Wikipedia: “Market capitalization/capitalisation (often market cap) is a measurement of size of a business enterprise (corporation) equal to the share price times the number of shares outstanding of a public company.”
2. or when :)
3. As proof that I was ever acquainted with the man whose startup may be next to rock the S&P, note that I’m just barely visible in the last of the photos in the image gallery on that linked blog post of Sachin’s.
4. I didn’t throw my planned Windows 7 party because I was ripped away from my everyday life and transported to Michigan for months to work on a film. it’s the sort of thing that can happen in my business.

Test of NeatVideo plugin; Noise removal from Canon T2i 6400 ISO clips from ZachFine on Vimeo.

if you’re on a fast machine, I’d recommend watching this full-screen with HD set to “on” –if you’d like to download the original QuickTime file rather than watch it embedded in a web page, there’s a download link low on the right side of the movie’s Vimeo page.

I shot some 1080p video in low-light with my Canon Digital Rebel T2i set to its 6400ISO setting, which resulted in very noisy video.

I tested the demo version of the NeatVideo for FCP filter to see if it could remove or minimize the noise. The results were encouraging, so I bought the “Pro” version of the plugin for $99.

This clip shows the results of the application of this filter to a couple of my more dramatically noisy clips. The filter renders very slowly, compounded by the fact that I’ve set the temporal filtration to use 3 frames.

You’ll see portions of the clips both with and without the noise removal, and split-screened sections for comparison. I think the result is pretty remarkable and usable, though the noise is peeking through the darker areas of the frame in the first clip. I wonder if I can smooth that out if I build a better noise profile or if I increase the temporal filtration?

Music:
“Do The Global Twist” by “The Neatbeats”, from the awesome album “japanese groupsound”.

I had to chop the song in half. Go buy the song or album to hear the very enthusiastic jam session in the middle of the track. Fun stuff.
