13. Saving and Editing Your Video

We should tell you right now that these camcorders all record in Advanced Video Codec High Definition (AVCHD) format. While this mode has the advantage of enabling shooting HD video, the format is still very difficult to process. Very few currently available software applications can edit AVCHD, and often you need to transcode into M2TS, a more easily recognized format. So much for consumer friendliness… Not to mention the computer muscle you need to be able to edit Full HD video: unless you have a Core 2 Duo and 2 GB of RAM, forget it.

DV, on the other hand, is still the simplest and most common format for video editing. All you need to do is connect the camcorder to a FireWire port and it’s automatically recognized. Capture is in real time since the data is stored on tape, so you need to record and rewind in real time. It’s time-consuming, but recording is done in sequences that are easily recognized by all editing applications.

Panasonic HDC SD5

The Panasonic offers software than can convert the video it records to the memory card. Called HD Writer, it’s a proprietary application that shows the video files in the form of thumbnails. You can join them one after another, but there are limits to what you can do with them. The camcorder needs to be plugged in to AC power to transfer video. Viewing your videos on a TV is very simple: you just connect it to the TV via an HDMI cable. It’s fast and works very well.

Caveat

Be careful not to modify your memory card; it must be formatted by the camcorder. And forget about using it as an external storage medium. Even with the source files, if the memory card has been modified or formatted by a computer, you won’t be able to read your files. That warning holds true for the Sony, too, and in addition, the camera blocks recording. Also, you won’t be able to export the video files on the card to your computer and then save them back to the card - the camcorder will no longer recognize them!

Sony also provides a little proprietary application called Picture Motion Browser that can process AVCHD. Installation is long, at around 20 minutes, and importing files is complicated. Plus, you’ll end up having to re-encode the files using Nero 8, for example, to be able to edit them with your editing software (e.g. Adobe Premiere). One positive point is that a PS3 can read the video stored on the card. If you have no Blu-ray player or game console, you can simply connect the camcorder to the television set.

Trouble with Corel...

canon hr10

Canon offers software for managing photos, but nothing in particular for video. A DVD with the Corel software suite is supplied, but it didn’t work - it needs to be activated with a code you must get off the Web, but the link led to an error page. All we’ll say is that it’s not very convenient... As a result, we weren’t able to process our video. On the other hand, to get a DVD you can read on a living-room player, you have to finalize it, which takes a few seconds. The MiniDVD is then playable - at least, on any player that doesn’t eat MiniDVDs.

hitachi dz-bd70e

Oddly, the Hitachi offers the simplest interface. The camcorder is recognized as soon as you plug in the USB cable. Installation of the software goes quickly, with information displayed in tabs. Viewing, however, takes fairly long. There’s a button for importing the sequences in M2TS packets; it’s simple, but takes a long time. There’s a big question mark about the HDMI cable. The camcorder wasn’t recognized by our Full HD TV… nor through a video acquisition card.

Caveat emptor...

Be aware that there are some poorly-advertised issues with at least some of these cameras.

It is common practice for cameras with full 1920x1080 sensors to scale the images to 1440x1080 before compression.

Also, camcorders that record progressive frames at 24pf tend to store their data as if it were 60i (60 fields/sec, interlaced) by duplicating and reordering parts of the video data. Most applications (Ulead Video Studio, Sony Vegas, etc.) believe the video files when they say they're 60i, so they try to interpolate between shifted and reordered fields in a process called deinterlacing. This results in smoother images that are not as sharp as they could be and ghosting of fast-moving objects. Camcorders that record to 30pf or 30p should not have this problem.

Also, as mentioned in the article, it currently takes some special applications (like Video Studio or Vegas) and/or a bit of technical know-how to even be able to read the M2TS files many of these camcorders produce.

You need to update your info. SDHC costs about $70 for 16GB not 4

You talk as if greater depth of field is a good thing. Actually, most camcorders have too much depth of field, causing the desire object to be in focus, and the undesired object to also be in focus. Pro lenses have a much shorter depth of field allowing the subject to be in focus and the background to be less distracting and out of focus. I would give canon more points for the shallow depth of field.

HD Camcorders are in their infancy at the consumer level. Expect lots of changes quickly right now. Even Pro HD cameras are changing quickly right now.

When viewing image19canonhr10 I see the famous Chroma Sampling Bug in the reds of the car contrasting against the black. Is this a bug native to the Canon camcorder, or a bug caused by the screenshot/editing software?
