Is it worth buying a high definition camcorder?

Q. Suppose I only have a HD TV, but don't have a HD player.

A. I think so - I've been doing HD for two years before I got a HDTV. The standard def video that gets burned to DVD is the clearest video you have seen - and when you get around to a HD or BluRay burner and/or player, you will have the source video in high def. You can also save the project as a data file and use your computer/media center connected to a HDTV (my plasma has a 9-pin xVGA computer connection and the video looks great).

The miniDV tape based camcorders will provide best available quality - and when you re done editing, you can export the project back out to the camcorder. You can then either use the camcorder as the playback deck or re-import that when you get the HD playback devices.

AVCHD compressed video (in hard drive and DVD based HD camcorders) compresses a LOT. When you compress up front and lose all that data in the capture process the downstream video when edited cannot recover that lost video. The best process is to capture the video with the least amount of compression - at the END of the process compress whatever you want... but to start with that compression (and lose all that video data at the start) is just poor planning and execution.

Take the hint from the pros - DV and HDV continue to be the best, cheapest and easy to use storage formats - that is why you don't see them using AVCHD compressed or MPEG2 compressed video.

Your computer needs a pretty good processor. And you need lots of hard drive space. DV (standard definition) video uses ~13 gig of hard drive space per hour of video. HDV uses ~44 gig of hard drive space per hour of video.

MiniDV tape is a digital media storage format and has excellent shelf life when stored in a cool, dry, place.

All miniDV tape based high-definition camcorders can also tape in standard def (4:3 or 16:9), so id you don't want to tape HD, you don't have to - and you will be ready when you want to start.


Question about Canon VIXIA HV40 High Definition Camcorder?
Q. Hey guys, I'm an aspiring filmaker who wants a camera that will shoot in good quality (for youtube) and will suit my short film needs. Is this the right camera?

Also, what type of files does this camera shoot in? I mean like .mov .jpeg .gif ect... because i bought a camera that only shot in .mov which is incompatible with windows movie maker, sony vegas, and adobe programs.

THANK YOU

A. The Canon HV40 captures standard definition DV and high definition HDV format video to miniDV tape. DV and HDV are the formats used by most camcorder in the $1,600 and up, prosumer through professional (up through the Canon XLH series).

DV and HDV are essentially low-compression digital video (HDV is MPEG-2). This is one of the reasons the professionals like it. The low video compression means less discarded data and higher potential video quality. At 25mbps, the lesser consumer grade MPG and AVCHD compression schemes cannot keep up - they compress a lot more resulting in more discarded video data and resulted reduced video quality.

The Canon HV40 is the least expensive camcorder available recording to miniDV tape that has a mic jack and manual audio control. Its Sony "competition" is the Sony HDR-HC9. The HV40 can do 24p and 30p captures - and is the least expensive camcorder with this flexibility. The HV40, in HDV mode can capture 1080i high definition video.

If better XLR mics are needed, then using an XLR adapter like those from juicedLink or BeachTek works great. Using a DoF adapter from Letus (and others) along with 35mm lenses can provide awesome depth of field can be accomplished.

As a miniDV tape based camcorder, the only way you will get video (standard def or high def) into a computer is by connecting a firewire cable (not USB) to the camcorder's DV port (not USB), and the computer's firewire port (not USB). The video editor must be able to deal with HDV format video if HDV is to be imported. USB will not work. USB-to-firewire cable/converter/adapter things will not work. If your computer does not have an available firewire port, hopefully it has an available expansion slot so you can add one.

You did not tell us which version of "windows movie maker, sony vegas, and adobe programs". Most of the recent Sony Vegas and Adobe apps should be OK with HDV. Only the current MovieMaker Live on Windows 7 can deal with HDV format video.

If you want to shoot like the pros, the HV40 and HC9 are the best consumer cams to do that.

BUT, they are consumer cams and with all consumer cams, they have small lenses and small imaging chip so their low light behavior is not so good (it will be grainy).

Consumer grade still cameras that happen to capture video typically capture to MOV (or AVI) format. Use MPEG StreamClip or HandBrake to transcode it - convert the file - to a format your editor can deal with. Use the least amount of compression (the video files will be huge). The only other camcorders that can record directly to MOV format that I know of are the JVC GY-HM100 and the GY-HD series pro-grade camcorders. The difference between these JVCs and the consumer MOV format is the consumer versions are really compressed video in those MOV file envelopes - the JV's are not as compressed.

There's a lot more, but the simplest questions can tend to have long and complex answers...
