MiniDV

MiniDV, or Miniature Digital Video, was a breakthrough for home video enthusiasts. The format used analog tapes, but encoded a digital signal. This is like the old style modems that sent a digital signal over telephone lines. When it first connected, you heard that series of squeals and beeps that was the sound of digital information being communicated in an audible format. These cameras are all able to transfer video to a computer through a Firewire cable. This technology ushered in the era of desktop video publishing. Software to edit video has become a standard feature for operating systems, and many excellent software video editing packages are available at a reasonable cost.

MiniDV is on the way out as a standard format, and the cameras are starting to get rare in stores. But, no other format has emerged which completely surpasses MiniDV in every respect. Every other format that has come out since MiniDV is also digital, but instead of storing a digital signal on an analog medium, the new formats store a digital signal on a digital medium, like a Hard Drive or Flash Memory. This makes a difference, because analog tapes have way more room for information than a Hard Drive or Flash Memory. That means that MiniDV required very little compression to make things fit. It’s able to store video information that hasn’t been shrunk down to a lower quality. Newer formats, because they have less space to work with, need to compress video down to fit onto a digital medium.

Compressed video isn’t a problem if all you want to do is play the video back. But, if you want to edit the video, then that compression means that you have less raw material to work with. When you apply effects and transitions, a compressed signal is not going to produce as nice a picture as raw video. For most people who just want to capture video of the kids as home movies, this isn’t a serious issue, but if you want to make a short film, you might want to pay attention to how much compression your video camera is putting on the video you capture, and what options the camera has to reduce that level of compression if you want video that is higher quality.

MiniDV tapes can stretch or become caught in the camera mechanism, but on the whole it is still a good option for Standard Definition, because it stores uncompressed video on an inexpensive medium, and the cameras are getting dirt cheap…if you can still find them.

Mini DVD

Mini DVD, which annoyingly has almost the same name as MiniDV, is an all-digital format. DVDs are highly compressed, and the minature discs don’t hold a lot of video. This format is most suitable for those who do not wish to edit video at all. If you primarily want to record and be able to watch the video on your DVD player without having to bother with editing it on a computer, then this might be a good option for you.

The primary drawback of this format is that discs need to be ‘finalized’ before they can be played on a regular DVD player. The process of finalizing a Mini-DVD can take up to twice as long as the recording time. This means that if you shoot an hour of video, it could take the camera as long as two hours after you finish shooting to prepare the DVD for a DVD player. Different cameras do better or worse at cutting this time down, but be aware this can be an issue and read some reviews on the camera before taking the plunge. This format is also on the way out, and while the discs are cheap right now, the cameras are getting rare, and are only available in Standard Definition models.

Hard Drive

Hard Drive video cameras are currently the popular choice. A 30-40 GB Hard Drive will store several hours worth of recording, and offloading it is quick and easy. MiniDV transfers video information in real time. This means that if you want to transfer an hour of video to a computer, it takes an hour to copy it over. Mini DVD takes a long time to finalize a disc. The advantage of a Hard Drive camera is that it stores computer files on a Hard Drive, just like the files you would store on your computer, so when it comes time to transfer from camera to computer, it only takes a few minutes to move those files, just like you were transfering a file from one computer to another. Quick and easy.

The inherent drawback of a Hard Drive camera is that the Hard Drive is sealed inside the camera and you can’t swap it out for another when it gets full. If you’re out shooting for a day or two then returning to your computer, it’s no problem, just offload the files. But, what happens when you go on a two-week vacation? Unless you have a laptop, you might run out of space pretty quick.

The answer is flash memory. When 2GB memory cards were the only reasonably-priced option, buying a dozen of those and swapping them out regularly would be a terrible hassle. But, now that 8 or 16 GB cards are getting into a decent price range, buying several of those cards gives you the flexibility to significantly increase the amount of recording time available on a Hard Drive video camera.

The good thing about Hard Drive cameras is that many of them are available in High Definition formats. This means that they can record in 720 or 1080 resolution. The tricky thing is that the abbreviation for Hard Disk Drive is HDD, and the abbreviation for High Definition is HD. So, there are a lot of letters stamped on the side of one of these units and you need to look closely to see whether it’s a HDD unit, yet only Standard Definition, or both HDD and HD. In order to be able to shoot in HD, a lot of these cameras will significantly compress the image they shoot and often will only offer 1080i resolution (interlaced) which alternates lines of video, not progressive, which displays each line each time. See earlier posts for a further explanation of the difference.

Flash Memory

The next step is to entirely skip the Hard Drive, and only use flash memory. As memory becomes less expensive, this becomes a more attractive option. Without a Hard Drive, the bulk of the unit can be significantly reduced and the power required takes less of a toll on the battery. These cameras can often take High Definition still images, and the line between where Flash Memory camcorders ends and regular Digital Cameras begin blurs a little. This is especially true since some regular Digital Cameras are now offering High Definition video as an option.

If I’m just taking a short video that I want to upload to Facebook or YouTube, then I just use a point-and-shoot Digital Camera. It is able to record at Standard Definition, the video responds reasonably well when I put it into a desktop video editor, and the result is more than enough resolution to look good online. If your job is posting to the Internet, you’ll want a real video camera, but if you’re just having fun, a regular digital camera is really all you need. Some Digital Cameras even come with a ‘YouTube’ mode, which records in the format YouTube uses, to make it easier to upload your videos.

Digital SLRs

Some Digital SLR (Single Lens Reflex) Cameras have begun to offer video. This is a huge development, because the ability to change lenses and control focus directly is really what separates consumer video cameras from professional equipment, and the price difference is HUGE between the two. Now that DSLR makers have started to add in video, they have been able to offer a product that gives amazing control over video shots for thousands of dollars less than professional equipment.

Early DSLR models that offer video do so with some limitations. The units that have just come out tend to overheat if used too long. The auto-focus these cameras use is often designed around taking still pictures and hasn’t yet been optimized to be effective when shooting video, so manual focus tends to be a better option. That manual focus is possible with these cameras is a real positive, but there are times when you just want the camera to do its thing. DSLR Video is still a very new thing, and some of the limitations that currently exist will soon be overcome, but this is a very exciting development and will soon become the must-have tool for those who are serious about shooting amateur video.

USB

USB stands for Universal Serial Bus. It’s a simple, easy way to connect things to your computer: Your printer, your digital camera, a thumb drive, a hot plate to keep your cup of coffee piping hot, a fan, a reading light, or one of thousands of useful or useless devices that are available for use with your computer. One of the great advantages of USB is that it not only communicates information, but is also capable of transmitting power. It carries information and powers the device. Larger devices that have significant power requirements tend to have separate power cords, but small devices often rely on USB for their power.

You can’t buy a computer these days that doesn’t include at least a few USB ports. If you need more connections than what the computer came with, you can buy a hub, which plugs into one USB port and provides 4 or more ports. This way, you can expand a single USB port to up to 127 devices: More than enough for a typical user.

Firewire

Firewire was standardized on Mac computers long before it became popular on PCs. When it was competing with USB 1.1, it had a significant speed advantage. It quickly became the standard for connecting MiniDV Camcorders to computers because it could transmit at 400 MBps (MB per second), which was 20 times the rate for USB 1.1 and necessary for transferring video files. Like USB, Firewire can both supply power and transmit data.

USB 2.0

USB 2.0 uses the same size of connector as USB 1.1, but it increases the speed of transmission from 20 to 480 MBps, 24 times faster. This made USB competitive with Firewire, but with the added convenience of being backward compatible with all earlier USB devices.

Firewire 800

Firewire came out in a new, faster version called Firewire 800, twice as fast as the original Firewire. For a while it was the fastest available, but it didn’t maintain its lead for long.

eSATA

SATA is a way to connect your computer to its internal components. When you install a Hard Drive or a DVD drive into your computer, SATA is the name of the cable you’ll likely use to plug it in.

A new type of SATA for external devices is called eSATA, the ‘e’ standing for ‘external’. eSATA runs at 3.0 GBps. That means it is three and a half times as fast as Firewire 800. Until USB 3.0 is widely available, eSATA is the fastest way to attach an external hard drive, and it operates at the same speed as your internal devices.

Before, with other types of connections, there was an advantage to connecting a device internally, because there was a bottleneck if you used an external device. With eSATA, you can attach devices which will theoretically perform at the same speed as a device you install inside the computer. eSATA is really only an advantage for devices which need to pass a lot of information very quickly, like an external Hard Drive.

USB 3.0

USB 3.0 is a recently finalized standard which will soon be included on new devices and computers. It moves the top speed of transmission for USB from 480 MBps to 5.0 GBps, more than 10 times faster. That makes it more than 50% faster than eSATA. And, because it uses the same size of connector as older USB plugs, it will be backward compatible with all earlier 2.0 and 1.1 USB devices.

Bluetooth

Bluetooth is a way to connect devices to your computer and devices to devices…wirelessly. It’s like USB, without the wires. It’s what connects your wireless headset to your phone, and that’s how most people know the technology. Originally, it was meant to replace USB, allowing you to connect your printer or camera to your computer without the hassle of plugging in wires. But, the only place it’s really taken off and become standard is with mobile phone headsets.

Laptop or Desktop

It’s very easy to add the newest connector type to a desktop computer. You can buy a card and pop it in your computer fairly easily. It’s a little trickier with a laptop. It isn’t as easy to add in what you want later on, so it’s important to pay attention to what a laptop comes with.

What are the Essential Ports on a Laptop?

USB

The absolute necessity is multiple USB ports – USB 3.0 if you can find it. USB is aptly named ‘Universal’ Serial Bus, because at this point, almost everything uses it.

Firewire

Get a Firewire port if you’re into video editing or audio recording. Older video cameras almost exclusively use Firewire, and most of the better professional audio interfaces do as well. It is worthwhile to be compatible with older cameras if you’re doing a lot of video editing. But, a Firewire port can be added through a PC card so even if you find a great deal on a laptop but it doesn’t have firewire, you can add it in later.

PC Card

PC Card is short for PCMCIA card, which is jokingly referred to as “People Can’t Memorize Computer Industry Acronymns”. It was a way to plug in modems and other devices back in the day which has now largely become irrelevant, but laptop makers still build them in. They’re only good for about two things: Adding in ports like Firewire that didn’t come with your machine and adding in wireless adapters.

They do a good job of those two things, though, because the cards can plug entirely inside your computer, making them very easy to just leave inside and not bother with. When you have a USB device, you need to unplug it and put it away before you pop your computer into your laptop bag or risk damaging the plug as it gets jostled around inside the bag. PC Cards just stay put, no muss, no fuss. They are often useful to have, but they’re a standard option on virtually every laptop, so advising you to make sure you have one is like advising you to make sure your laptop comes with a keyboard.

eSATA

Get eSATA if you want to use an external Hard Drive or other high-speed device, although if your computer comes with USB 3.0, then eSATA becomes redundant, and you should only get one if you want your computer to be able to interface with absolutely anything that it might have to. There’s nothing worse than being on a deadline or in a presentation and a file you absolutely need is on a device you can’t access. But, very few devices are eSATA-only. Most that have eSATA also offer USB as an option.

HDMI

An HDMI port is becoming somewhat standard on laptops these days. This type of port is solely for connecting your laptop to a Big Screen TV, but it’s a handy thing to have. Especially if your laptop comes with a Blu-ray drive, because then it can double as a component in your home entertainment system.

Bluetooth

Bluetooth is nice to have in case you want to connect a keyboard or a mouse to your computer wirelessly, but this technology hasn’t replaced USB as it was originally hoped it would. I wouldn’t go out of my way to include Bluetooth, especially when you can just buy an adapter to plug into a USB port for $10-20.
