The SanDisk Sansa View 16 GB

Geeks.com, the place for cheap mp3 players, sent over the SanDisk Sansa View 16 GB for a review, along an 8 GB microSDHC card for it. In the box, we also received its USB cable (proprietary connector is used) and some standard earphones.

It took about 2 hours to fully charge the player the first time. The UI loads within 10 seconds and greets you with a scrolling interface. The icons are: Music, Photos, Videos, and More (Radio, voice recording, device settings). When a song is playing, a new icon appears called “Now Playing” (it doesn’t show up otherwise). The UI is controlled by an iPod-like wheel that is actually rotatable rather than touch-sensitive. There’s also a “Home” button, a power on/off/HOLD slider on the side of the device, next to the microphone. The 3.5mm headphone jack is placed on the bottom of the player, next to the proprietary USB connector. The 2.4″ LCD screen is very readable and supports many colors, however the font used in it is pretty ugly.

The device sports 16 GB of internal flash, but it also has a microSD card slot. We tested the slot with an 8 GB card that Geeks supplied for the test.

The music menu has all the normal options one would expect, e.g. playlists, artists, songs, podcasts, audiobooks, genres, and a few more, like “recently added”, “my top rated”, and [voice/FM] “recordings”. When you click on a song, it will start playing, with the band name, album title, song title on the top, followed by the album art, and the progress bar. Clicking the bottom part of the wheel, it will bring a new menu up, that includes options like “Add to Library”, Rate music, repeat, shuffle, EQ, Go List and even “Delete song”. The device supports MP3 and WMA, but the latest firmware adds AAC support too (.m4a). Audio quality was very good.

The Photo menu has some nice slideshow options, while the video menu allows you to resume a video you had started watching earlier. It supports WMV and h.264 videos up to the QVGA resolution. The FM radio option allows you to set presets and even record radio stations, while the voice recording is also pretty straight forward too.

It all sounds good in first glance, and someone could go as far as to say that this might be the next best mp3 player after the iPod, if it wasn’t for the inconsistent UI. There are multiple ways to go “back” to a previous menu, that make the whole usability pretty confusing. On that, we should add that the device failed to read all of our AAC’s album art, and about 40% of our mp3 album art (all jpeg files embedded in the tags, ID3Tag v2.3). The Nokia cellphones also only read about 50% of my mp3’s album art, but if at least there was consistency in the failing of the two devices, I would have talked about a bug on my tagging, but both devices fail on different songs, so it seems that they are just buggy (iTunes and Mp3Tag can read all of them for example).

Also, the player is advertised as having gapless playback, but while the feature seems to have been worked on, it was certainly not as gapless as the iPod is. There was still a small sound heard when hoping between tracks.

The biggest problem however was the database corruption that I experienced twice within the last 3 weeks. The device would fail to recognize that it had GBs of songs in it, even when the “system info” utility correctly reported how much of the flash space was used. In order to fix the problem, you need to either delete or add a song via a PC, so you can force a re-generation of the DB (that takes up a few minutes when the device is full). Problem is, if you are high up in the mountains camping, and you don’t have a laptop with you, here goes your music for the time being.

The USB usability is a bit weird too (the UI for it doesn’t make it clear which mode is set on). More over, when I try to “eject” the device from Explorer, the device reproducibly crashes my Explorer (other devices don’t do that).

On the up side, the player can deliver over 25 hours of continuous playback, which is a feat. Overall, this is a good player if you just want to listen to some music and radio without having high expectations of a consistent interface and usability. It’s definitely better than most cheap mp3 players out there, but nowhere near the mighty iPod (or even the Zune).

Benchmark: The best HD 720p digicam around

When I learned that the new Canon SX200 IS digicam has not only exposure compensation in video mode, manual focus in steps, but also the very important exposure & focus locking, along manual white balance/color/sharpness/contrast/saturation/skinTone/R/G/B, it was a sure sale for me. So we went with my JBQ today at Costco and bought one for $330 (he got a toy too, he bought a 120GB iPod Classic to fit his 50 GBs of music).

The camera records in 1280×720 resolution, at 30.00 fps, at 24 mbps bitrate, with the h.264 (baseline level 4.1) codec & mono uncompressed audio, in the MOV container. Now, think that the best AVCHD camcorder out there, also records at a maximum of 24 mbps, but at the much more demanding 1920×1080 resolution. This means that 720p at 24 mbps is actually a very solid, very generous bitrate.

I set up a scene on my balcony and tested SX200 IS’ video capabilities against my Panasonic FX150, Kodak V1253, and my trusty Canon HV20. Please note that while I shot everything in auto, I turned down to the minimum the color/sharpness/contrast/saturation/SkinTone of the SX200 IS, because that’s the look I like the best (and it’s more color-grading friendly). Please take a good note: the DEFAULT video look of the camera is MUCH more punchy and sharp in every way, which it might be what some consumers want, but definitely not what a serious videographer wants (the damn thing doesn’t color grade otherwise).

The Panasonic has a larger sensor, it records 24 fps in MJPEG at 25 mbps. Unfortunately, this bitrate doesn’t seem to be enough for the less-optimized MJPEG codec, as the picture shows below. The very famous Panasonic LX3 produces the same looking video as the FX150 btw, the two digicams are more alike than different in their video behavior. The Panasonics have exposure compensation, but not locking, creating a very jumpy exposure effect, which kills the seriousness of the footage captured. On the upside, its MJPEG format is very smoothly editable under Sony Vegas, unlike the much slower format of the SX200 IS.

The Kodak V1253, records in 720/30p at 12 mbps MPEG4-SP (simple profile, the same kind of the mpeg4 format as… cellphones record as). The Kodak cameras are plagued with color problems mostly, and the fact that they have absolutely no controls (not even exposure compensation). Under Vegas, its format is near-uneditable, and makes the editor very crash-prone (it realistically requires proxy editing). What Kodak has for it instead, is cheaper prices, starting at $120 (I guess, you get what you pay for).

The Canon HV20, is an HDV camera, shooting 1440×1080i mpeg2 at 25 mbps. In order to properly compare it with these mostly-30p 720p cameras, I had to shoot in the shade with an ND4 filter, at 1/30th shutter speed. I always have Cinemode ON btw, in order to emulate the filmic look (which is why the screenshot is not very sharp and might surprise some of you). I used 720/60i project properties on Vegas (in other words, I trusted Vegas to do a proper resize of the footage), and I used “blend fields” as the de-interlacing algorithm as it provided the best-looking image compared to not de-interlacing at all, or using interpolation (I tried all three options, and analyzed their best(”full”) captured screenshots before I decided which one to include above). Compared to the SX200 IS, it has of course many more options and controls since it’s a real camcorder, but most importantly, it has a better lens that provides twice as much background blur.

As you can see, the HV20 (as expected, even with the less sharp Cinemode mode) and the SX200 IS kill the competition out of the water. Yes, I know of the newer Panasonics that use AVCHD-lite instead of MJPEG, but they still don’t have as much control or bitrate as this Canon camera! Sure, the SX200 IS doesn’t have shutter speed control and a 24p mode, but compared to ANY other consumer 720p digicam below $500, it has the MOST controls and the BEST image!

If they add shutter speed control and 24p option in a future model (even without IRIS/ISO control), that team at Canon should get a medal.

Verdict: get one yourself! Don’t bother with its competition (unless you prefer to buy an actual camcorder, or a DSLR).

Update: Read the comments below, there’s some more info.

Canon 5D: THE camera for music videos

I was just looking at some videos shot with the 5D, and many of them are official music videos. And it makes so much sense, the 5D is the best cost-effective camera for this specific job. It seems that many professional filmmakers who shoot music videos by trade, have flocked behind the 5D. At $3,500 (with two medium quality lenses) is a bargain.

With its 30p, you can shoot the video with 25% sped up audio, and then slow-down the video in post to 24p to match the original audio (confused? read here). Then, there’s the unparalleled quality of the videos straight out of the 5D (higher bitrate than any HDV/AVCHD prosumer camera), its color and image control that can emulate film looks, shallow DoF, and now, full manual control. The fact that its audio abilities are less than ideal is irrelevant towards shooting a music video, since the audio is added later.

At this point makes absolutely no sense to buy any prosumer camera ($2,000 to $10,000) and put a 35mm adapter in them to shoot music videos. Because, either the bitrate of these cameras can’t surpass the 5D’s (e.g. EX1, XH-A1), or the resolution is actually lower and adding a 35m adapter kills quality even more — even if the bitrate is higher (e.g. HVX200).

It only makes sense to get these cameras instead if you actually need true 24p recording (which is coming to the 5D too, and it’s not necessary for 25% slow-downed music videos anyway), if you need 60p/60i for better slow-motion, or if you need better audio options.

In other words: if you are in the business of shooting music videos, get a 5D and use it as your main camera. And if you happen to need better slow-motion abilities, get a consumer Canon HF-S100 that shoots in good quality 60i (when interpolating to 540p it creates a 60p file that produces smoother slow-mo).

Of course, for music bands that don’t have that kind of money, they can try my guide for shooting their music video for less than $430.

UPDATE: Heh, what do you know? This article was published today at NYTimes!

The new Apple announcements

It was WWDC day today, and new products were announced. Here’s my take:

Mac OS X: Indifferent. This was like, the 100th rewrite of Finder. It remains to be seen if Quicktime will be any faster with the new hardware acceleration. The $29 upgrade price was good though.

iPhone: I wanted a true 16:9 OLED screen at 4″ and 640×360 resolution. That would fit almost on the same size iPhone as the current ones (because of the 16:9 instead of 16:10). I also wanted a VGA video-call camera. Maybe next year.

Macbook Pros: I might opt for the new 13″. It was very interesting seeing Apple bringing back Firewire, as there was a huge bitching about the lack of Firewire by HDV prosumer and fw audio users for the last year’s model. The backlit keyboard is a very good addition too. However, compared to the other candidate for my next laptop, the MSI U200, it’s heavier, has a lower res, and it costs double the money. I haven’t decided yet for which of the two laptops I will be going for. I prefer a Macbook, but does it worth the extra $800? I am not so sure.

I wanted a new AppleTV too, one that can decode 1080p and allows for third party codec plugins.

Canon 5D Mark-II: 50% there

Canon announced today it will release a firmware update for the EOS 5D Mark II allowing users to manually control exposure when shooting video. The firmware update will include the following manual controls when shooting video:

* Full aperture selection
* ISO speed: Auto, 100 – 6400 and H1
* Shutter speed: 1/30th – 1/4000th second

This, in addition to its exposure compensation, exposure locking abilities, and gamma/color/picture settings that can be modified via templates generated with Canon’s PC/Mac accompanied 5D application.

This new firmware makes the 5D MII the best video camera out there for DV Rebels, and by far the best DSLR video camera out there. Of course, there are a slew of video-specific hardware features missing (e.g. XLRs), but in terms of actual visual quality obtained with its 38 mbps h.264 files, and with its new basic control options, it beats anything in that price range. Especially if you have some good lenses for it.

The only other feature that matters for us DV Rebels and that’s _really_ missing is frame rate support. 24p (=23.976) is still not there, and its 30p is 30.00 fps instead of 29.97. Additionally, 720p at 60p would have been nice too (for slow-motion usage). If Canon fix these two small problems (easy to implement), it has a real winner in its hands. There was a rumor a few weeks ago where someone said that Canon doesn’t want to implement 24p in its 5D in order to not cannibalize its prosumer cameras, but truth is, people are asking for it — a lot. They will have to comply.

In our home, we are 60% ready to buy the new 5D. Before today’s announcement, we were 10% ready. So we are close. But still not there. Add some frame rates that make sense, and then we will buy it with closed eyes. Promise.

Battery expectations

Some people are whining online that their smartphone doesn’t last for more than 1-2 days without recharging, while their 5 year old phone could last over 5-6 days before need any recharging. This is a fallacy. The new phones have better battery life than the older ones.

Consider this: Phones like a Blackberry, iPhone, Android, Symbian, etc. come with many media and internet-heavy applications. It’s now customary to check for email, to check Twitter, to check the internet-updated Weather app, to check stocks, sync between the phone and various online accounts many times a day, to check some RSS or web pages, to use Y! or Google maps. And on the side, play some music, quickly visit youtube, and maybe even watch a small TV episode while waiting on the bus.

All these things are features that you couldn’t do 5 years ago. At least not in a way that would be pleasurable. 5 years ago, you would check your voicemail, your SMS messages, and just do voice. And that was about it. No wonder you could do over 5 days in battery life.

What changed is HOW we use these phones. We now use these phones as mini-laptops. And yet, we expect them to have the same battery life as they had when they were dumb bricks. I am sorry to say that battery technology doesn’t move as fast as software tech does!

And then there’s the other thing. On platforms that allow background apps, the third party application designers only care about their little app and not the whole device. As long as they can invoke a network ping or connection when you are not looking to sync something, they are happy. Very seldom these app developers think what would happen if there are 5 (or 10) background apps installed and doing their own thing whenever they damn want. The user will see a big drop in battery life, and will place the fault at the phone manufacturer instead.

In conclusion, be objective when you are damning a manufacturer of bad battery life. Maybe there’s something you can do to better the experience (short of inventing a new kind of battery altogether).

What I look for in a camera

When I look to buy a cheap digicam/digirecorder (NOT a camcorder) these are the video features I first look at, in this specific order:

1. Does it have exposure compensation?
2. Does it have exposure locking?
3. Does it have shutter speed control?
4. Does it have color/gamma settings? (low saturation/contrast/sharpness)?
5. Does it have manual white balance?
6. Does it have focus locking?

The first two are the most important video features one should be looking for. Without them, you can ruin your shots no matter how careful you are. For example, the Flip/Kodak digicam/digirecorders don’t have any of these features. The Panasonic ones only have #1 and #5. The new Canon ones have #1, #2, #4, #5, #6 making them a better buy overall (missing only shutter speed). Of course, a choice between 24, 25 and 30 fps would have been nice too.

Notice that I don’t list gain or aperture control. If I was looking for a still picture camera, aperture control would have been much higher up in the list, but for video, shutter speed is more important — at least for the kind of videos I am shooting. Needless to say that for all of my HV20 videos, none was shot in aperture mode. They were all shot either in shutter speed mode, or Cinemode.

Update: JBQ wrote a similar blog post too, about still cameras.

The case of the iPod Nano

We are flying to Europe soon, and I was keep trying to convince JBQ to get a protective case for his 4th Gen iPod Nano. There’s no time now to go to Frys to get one, so I thought he will fly without a case.

I went to Longs pharmacy today to buy some masks (we will be changing 3 planes, so better safe than sorry), but they were out of them. In one of their baskets full of random items sold at 1/3 of their price there were some iPod cases (yes, sold at the Longs pharmacy). Anyways, they didn’t have any for the 4th Gen Nano, so I thought that this is it, JBQ won’t have a case for his player.

Fast forward 15 minutes. I was walking back home, when I literally stumbled into this, red color, perfect condition. In the middle of the street. I took it home, sanitized it, and it looks like JBQ will have a Nano case after all. It’s all kind of funny, really.

The NAB non-show

What a freaking let down. RED, JVC and Sony revealed no new products or updates whatsoever, while Canon rehashed their older ones. Unless Canon announces new prosumer products tomorrow, I will completely lose my faith on that company. They make no sense anymore.

Panasonic on the other hand already announced a bunch of stuff, including a very impressive 3D camera that uses AVC-Ultra (200 mbps bitrate!), and the HMC-40 (press release, news report, big picture). The important thing here is that Panasonic realized that there’s a hybrid consumer-prosumer market (and they even called the HMC-40 a “hybrid”). They are the firsts to do so, as far as I am concerned. I have been burbling about that hybrid need for 1.5 years now!

The camera uses three 1/4.1″ sensors, 12x zoom, 21 to 24 mbps VBR AVCHD recording (unfortunately, no constant recording at 24 mbps), 24p/30/60i at 1080p, up to 60p at 720p, cine-gamma presets, manual controls, enough buttons and focus ring, 2.7″ touchscreen, XLR/handle-bar add-on (sold separately), and Panasonic’s dynamic range stretching algorithm. Price is a bit steep at $3200 though for these specs.

The real let down on this camera is the sensor size though. Even if it has 3 sensors, each is still of minuscule size, and the lens seems to be consumer grade too. Which means that background blur will probably be worse than the $500 HV20’s. This is a deal breaker for me. I would have preferred a single 1/2.0″ sensor rather than three at 1/4.1″.

So, even after the much awaited NAB show, there’s still no camera that does what I need. This HMC-40 came SO CLOSE. So close. But still no cigar. However, there are rumors that Canon will update the Canon’s 5D Mark-II firmware with more video abilities, so if that happens and they add 24p frame rate, zebra support, and shutter speed support, that’s the camera I will be getting — even if it doesn’t have other features that camcorders do. We have about 15 lenses that go on the 5D anyway.

Enough with this shit though. This was a letdown.

In search of a Hi-Fi system

Our 300 CD changer holder is out of space with our 400 CDs, and there’s no way to playback our digitally-bought 3.5 GBs of mp3/aac files that we have around. We need either something like the AppleTV where we can move all our 35 GB of ripped music in there, or a new 400 CD changer system like this one but with the ability to also play mp3/AAC and have a UI viewable via composite-out.

As it stands right now the AppleTV doesn’t do what we need because it doesn’t have composite-out, as I would like to use a small portable DVD player as external monitor for it. I simply don’t want to hook it on our 50″ TV and have our TV “on” all the time just so we can listen to music. If that was the case, we already have a PS3 that can do that (I currently use it for video playback only). It’s such a shame that the AppleTV doesn’t do RCA because it would have been perfect for music. :(

As for the linked Sony CD changer above, it doesn’t do AAC, it doesn’t have a hard drive (and I am not sure it reads mp3 files from DVD-R disks and not just from CD-Rs), while its UI simply sucks from what I read online.

The funny thing is that the device we need actually existed once as a prototype product. Back in 2000. And it was created by my husband’s then-company, Be Inc. The Be Aura was a beautiful device (unfortunately I couldn’t find any picture of it online to link, there used to be one), with a specialized UI, a remote control, and had a nice monitor too. Surely you could put together a small PC today with Windows Media or Linux on it, but it will still look like an ugly ass PC in our living room. That was a targeted device like the AppleTV, not a quickly-put-together PC job. Update: The device I was thinking was called “HARP”, btw. “Aura” was the software platform for it.

So, we basically need a device that can accept a SATA drive with mp3/aac and preferably FLAC music, has composite-out with a usable UI, and good digital-out for audio. The CD changer feature is optional as long as there’s a hard drive in there and there’s lossless FLAC support. So, do you know anything that would work for us?

Update: We might just be going for the Sony 400 CD changer it seems. We feel that the home entertainment systems today are in a state that resembles mobile phones before the iPhone arrived. The Sonos system is close to what we need, but no cigar.
