How do I record with a video camera and watch at the same time?

Q. I coach football and I would like to hook a camera up to a laptop to allow me to re-watch plays while someone next to me continues to record the game. Is there any software of hook-up that would allow me to do that?

A. Video servers of the type used in broadcast television stations sometimes have the "playback while still recording" option. Not laptop class equipment. try google to get vendors for video servers.


In movies and music videos what kind of camera?
Q. In movies and music videos what kind of camera do they use to film it. I noticed the picture is so clear, and I wanted to know if they used a speacial kind. And how much would one cost?

A. The other posters are correct - but for a little more detail... typically, the professionals do not use consumer-grade camcorders. Even if it looks like they are using a consumer camera, that video is not used - it is typically captured by a pro-grade camera and the video is made to look like it was captured by a consumer cam.

If they even use a camcorder, at the low-end, check out the Sony HVR-Z1U, HVR-Z5U, HVR-Z7U; Canon XH and XL series or the Panasonic HVX200 series. Remember, this is the low end. The Sony HDCAMs and XDCAMs are more common at the mid and high end as are the Panasonic DVPRO systems.

Please note than NONE of these records to the highly compressed consumer-grade MPEG2 or AVCHD that consumer hard disc drive, consumer flash memory or consumer DVD camcorders capture. But many of them do record to DV (standard definition) and HDV (high definition) which is the same at that used by ALL miniDV tape based camcorders whether consumer or professional grade. DV/HDV can also be store to external hard drives connected to miniDV tape based camcorders (like the FireStore drives from Focus Enhancements) or, certain flash memory (like the P2 cards used by the higher end Panasonic camcorders. Then there are the special high capacity DVDs used by a few of the high-end Sony pro-grade HDCAM and XDCAM systems...

If they are working in a studio, it is likely they are not using a camcorder, but regular broadcast cameras... watch your local news or Jeopardy (the game show) or any professional football game - they usually have a shots of the the huge studio broadcast cameras at some point...

Are they "special"? Yes, they all have much larger lenses and imaging chips that consumer camcorders do not have. They are nearly ALWAYS on some sort of steadyting device (tripod, shoulder-mount Steadycam/Glidecam vest and articulating arm system, camera crane, etc... and NEVER just handheld. The camera itself is usually a few thousand. The lenses can be as much or more than the camera and the steadying system can also be as much or more than the camera...

In the movie environment, most large budget movies still use film cameras. Check out Panasonic's VariCam, Sony's CineAlta, Arri or PanaVision cameras... A few are moving to digital cams like the Red Scarlet... These systems can easily be $100,000 or more per camera.


Which camcorder is good for filming soccer games?
Q. I want to film my brothers soccer games and training so I wanted to buy a camcorder.
My budget is pretty low so nothing fancy.
My friend is selling Samsung HMX-F80BP, and I want to know can this one record soccer/football games. I would use tripod and just go left right left right with occasional zooming.

I also thought about Canon vixia m30 or r30 but those are a bit over budget so I probably will reconsider them in a few months.

A. HD Camcorders and DSLR Cameras interpolate the video, which means of every 25 frames of video, 4 or 5 frames are taken by the lens assembly; the other frames in between these are filled in by the camcorder inner circuitry, thus giving you not true video. It looks like this -one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, one frame from the lens assembly, 7or 8 from the electronic circuitry, from front to back of the video. Near impossible to edit, even when you have the Multi port processor computer with the big 1GB Graphics card and a Sound card that is required to edit, view, watch and work with the files these camcorders produce.

Consumer Level HD Camcorders and DSLR Cameras have 4 problems. 1) Blurry, fuzzy, out of focus areas closely around people in videos taken by consumer level HD camcorders. 2) Any movement, even a wave or lifting an arm, while in front of a recording Consumer Level HD Camcorder and DSLR Cameras, results in screen ghosts and artifacts being left on the video track, following the movement. Makes for bad video, sports videos are unwatchable. 3) These Consumer Level HD Camcorders and DSLR Cameras all have a habit of the transferred to computer files are something you need to convert, thus losing your HD quality, to work with your editing software. 4) Mandatory maximum record times - 1 hour, 30 minutes, 8 minutes, 3 minutes – four different times advertised as maximum record time for some Consumer Level HD Camcorders and DSLR Cameras. No event I have ever been to is that short. Either take multiple camcorders and DSLR Cameras or pack up with out getting the end of the event on video.

MiniDV is currently the most popular format for consumer digital camcorders. MiniDV camcorders are typically more affordable than their HDD and DVD counterparts. Each MiniDV tape will typically hold an hour of footage at normal recording speed and quality. MiniDV tapes are available for purchase at not only electronic and camera stores, but also at drugs stores and grocery stores, making them easy to find while your on vacation. There are literally hundreds of MiniDV camcorders available; both in standard and high-definition. And add the fact that to get a HD camcorder that could produce better video quality footage, one would have to spend in excess of $3500 for that camcorder that could produce higher quality video
