Equipment Evaluations

Having used my new equipments for a few times here are my thoughts,

1. Nady CM-2S
Brilliant sound quality. Really the result was better than what I expected, worthing every penny of the $99.95 price tag. Here is a test clip; the original sounds even better.

2. SignVideo XLR-PRO
Again more useful than I expected. The ability to adjust volume on the fly is so useful that the unit is now a necessity.

3. Rode Videomic
Despite being the most expensive audio equipment ($149) I have I actually did not used it a lot for the past two weeks–I have been recording music mainly, while in other situations the speakers use microphones connected to speakers anyway. But for the few moments I did use the Videomic it seems to work well.

4. Yunteng VCT-880RM
This Chinese copy of Velbon DV-7000 works fine, but nowhere great; then again it only cost me HK$235 (~US$30). On my part I need to practice my panning skills and remember to turn off optical image stabilization (ouch!).

So My New Equipments Arrived

Remember I said I have expensive equipments coming in? This has finally materialized on yesterday. To be fair these equipments are expensive for me; they are no where near expensive side in the spectrum of video and audio equipments. So what did I received? 2 microphones, 1 mixer and 2 light bulbs in total. I shall ignore the 2 light bulbs for the time being since they contribute only a fraction towards the total cost I paid for the 5 items.

1. Rode Videomic
The critically acclaimed pro-sumer microphone. It looks like what you see on TV station camcorders, and there is some truth to this–Videomic is a mono shotgun microphone excel in isolating dialog in front of the camera.

2. Nady CM-2S
While nowhere as famous as the Videomic, Nady CM-2S is a reputed stereo microphone with a pretty flat response for a wide range. It’s primary purpose is for live music recording. I originally pondered if I need the CM-2S on top of the Videomic. After some quick testing it is clear that it is necessary–Videomic is not designed for recording music and indeed it does not do very well in that arena.

3. SignVideo XLR-PRO
XLR-PRO is a mini-mixer that screws to the bottom of any camcorder. It adds two extremely useful features to the camcorder it is connected to: First it allows input and mixing of two independent mono channels and second it accepts XLR plugs. XLR plugs are those 3-pin microphone plugs you see everywhere except your home; they are virtually unsupported in any pro-consumer-or-below camcorders, probably due to space and cost concerns. Mini mixer like XLR-PRO allows the connection of widely used microphones like Shure’s SM series to the host camcorder.

This is probably the worse picture I have taken in years but it demonstrates how my GS400 looks with the Videomic attached on top and XLR-PRO beneath.

Video Taking 2

“To get a job done one needs the right tools”. You cannot expect the quality of DSLR from a prosumer; a cheap tripod could very well break and drop your pricey camera (yeah that happened on me). The same for video taking. What am I trying to say? I have expensive equipments coming in next week…

If you are a Star Trek fan–particularly for the original series–take a look at this site:

These people are crazy.

Video Taking

Lessons:
1. Auto exposure is not to be trusted–manual adjustment is often necessary;
2. Camcorder LCD is not to be trusted–always use a monitor;
3. Samsung Q1 works well as a monitor (what a waste) but might lack juice for real time encoding

I really begin to appreciate the manual controls of my Panasonic GS400; I am glad that I kept one–out of three–for myself back in last year.

I also discovered this great video upload site: www.vimeo.com. It has a few advantages over its competitors:
1. No time limit (YouTube’s limit is 10 min);
2. No individual size limit–only a weekly limit of 250MB;
3. Relatively high quality
4. Option to download original

Apple Introduces iPhone

So Apple came up with “a combination of a video iPod, a Wii controller, and [smart] phone”. Besides a touchscreen system which Steve Jobs described as “revolutionary”, iPhone runs OS X. While thats could potentially become a devastation for Windows-Mobile-based Smartphone, it remains to be seen how an–relative to desktop and laptops–underpowered mobile phone handles a desktop OS, and more crucially desktop applications. No specifications on processor type and speed have been released at this point, but I bet you will not want to install many common applications on it.

Now as for the “revolutionary” touchscreen. Despite all the hype many–maybe most even–people dislike on-screen keyboard when they actually have to use it. The reason why Blackberry etc. include thumb keyboards is not that they cannot come up with on-screen solutions but that people prefer real buttons to virtual ones. But who knows, maybe Multi-touch is revolutionary.

Samsung Q1

Samsung Q1
I have to admit that I have a taste for portable devices: first it’s PDA, now it’s UMPC. Despite lukewarm reviews everywhere, Q1 comes quite close as my dream machine. In particular, it addressed many inadequates of PDA. Here are the pros:
1. Size: Q1 has the size of an average package book; with a weight of less than 800g its very portable.
2. Screen: At 7″ physically it is much bigger than anything one could find on a PDA.
3. Touch-Sensitivity: I really like touch-screen–mouse-pad and pointer drive me mad. Touch-screen also allows me to work one-handed, something I really need when I am standing. I actually find entering through Dialkeys, a virtual keyboard bundled with all UMPC, somewhat enjoyable…
4. Windows XP: Since Q1 runs XP Tablet, anything that works on a desktop theoretically works in it to. This is an unbeatable advantage over PDA’s, which need specialized softwares. Just yesterday I demonstrated the concurrent running of World of Warcraft and a program I wrote to a research colleague.
5. CF-slot: This is how Q1 wins my heart over Asus R2H, another UMPC. I need CF-slot to load photos from my DSLR and R2H only has a SD-slot.
6. Spec: Nothing spectacular here–actually Q1 is arguably underpowered–but as a PC it’s still way better than any PDA. I could barely open jpeg’s from my EOS-300D on my X50v, not to mention RAW.
7. Connectors: 2 USB ports and VGA out, things that are not on my PDA, is really all I need.
6. Price: I was originally look for ultra-portable laptops but those are expensive. At ~$1000 Q1 costs at most 2/3 of many popular ultra-portables.

There are quite some cons too:
1. Underpowered: Equipped only with a Celeron M 900Mhz processor, 512MB RAM and 40GB hard disk, it’s not a fast computer in any sense. Q1’s 7″ touch screen is almost triple that of my x51v in size, yet at a native resolution of 800×480 it hardly offers any advantage in resolution.
2. No microphone jack: The built-in microphone works great, but it would still be great to have the option to plug in an external one.
3. No videocam and GPS: Not something I would use often, but Asus’ R2H has both.
4. Mediocre Battery life: This is by far the biggest drawback–battery cannot hold much longer than two hours.
5. Price: I did mention it cost a thousand bucks…well.

In the end I am happy: Q1 is the solution to my need; neither PDA nor laptop could address my need as well as the Q1 does. And while many condemned Q1 to its demise, I do see there are others holding the same opinion as I do. Sometimes you just have to leave aside the zillions of reviews and make your own choice.
