What does it mean when a dslr camera has a recording limit?

Because all DSLR cameras, when recording Video, irregardless of ambient temperature, over heat in 12 to 16 minutes when shooting Video. Then take several hours, some times an overnight period to cool down enough to use. 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 http://simplevideoediting.com/learn/part1_camcorder_choices.htm http://simplevideoediting.com/learn/part2_connect_camcorder.htm http://usa.canon.com/cusa/consumer/products/camcorders/consumer_camcorders/vixia_hv40#Overview
