DSLR cameras have been able to evolve so much that there days they are just as good as any other video recording device or equipment. DSLR cameras have all kinds of innovations to help with the improvement in the projection of pictures. The same thing can be said when recording videos with a DSLR camera. To answer this question, not only are DSLR cameras good at video recording but they are very good and in a lot of cases beyond fantastic.
There are specifically marketed DSLR cameras that are tailor made for video recording. As with any technology, the innovations and the evolutions with DSLR cameras are on par or exceeding that of other technologies. I would certainly highly recommend anyone purchasing a DSLR camera in order to do video recording with. With a DSLR camera they are going to get the same top notch technology that they would have gotten if they purchased a regular video camera recording device.
Before, only camcorders were able to record videos not cameras. But as the photography technology improves, and digital cameras become available, people can now easily record videos using DSLR cameras. DSLRs are good at taking videos as you can easily see the scene you are recording on the LCD screen.
Depending on the model, a good DSLR can shoot videos in low light without sacrificing too much of the quality. You can easily attach external microphones if you want to produce videos with more crisper and clearer audios. Aside from those, you can easily transfer and edit your recorded videos by removing the memory card or directly connect your DSLR to your computer.
