Multimedia, AV With the explosion of (mostly Canon's) video HD dSLRs in the last few months, purchase decisions for video editors have shifted, depending on which editor can deal with h.264 the best way. Until recently, users had to either use "proxy" files, or transcode to an intermediate format. Then, Adobe's Premiere Pro CS5 came in to change this by being the first video editor to fully utilize nVidia's CUDA technology and achieve real-time playback for Quicktime dSLR, and AVCHD footage.

You will never get from a dSLR like the Canon 550D/T2i the sensitivity of a camcorder like the Panasonic HDC-SD 300 and similar.

This makes a huge difference when for instance shooting your kids indoor with sub-optimal light and they move...


That's plain wrong, the only advantages that dsrl have vs camcorder are:

big sensors with GREAT and never seen before in consumer market light sensitivity

Small DOF

many many expensive lenses 'till you are bankrupt ;)

That's the case for a single-shot scenario.
Beware that dSLRs can shot 3-4 fps in photo-mode.
When you go in movie-mode (24-30 fps) it is a whole different story.
Shoot your films with a dSLR and digital HD camcorder, and compare for yourself.

See webepisode 2

Acording to this teste the dsrl are better that film as light sensitivity is concern

I have a canon camcorder HF10 and a canon t2i and I can say that the t2i is far better in low light

You don't get the full advantage of the big sensor however. You do get the shallow DOF advantage but not the sensitivity advantage.

They don't read the whole sensor and put together data from all the pixels into a lower resolution, such as filming at 21 megapixels on the 5DmII and saving in 1080p. They only store the needed pixels AFAIK so that leaves out a hell of a lot of sensor area. For 1920x1080 that will mean like you're only reading 1/10 of the sensor of the 5DmII. So yes, much bigger sensor but you lose 9/10 of the sensitivity advantage ..

It's waay too much data to fetch those 21 megapixels @ 14 bits (not times three since the pixels aren't RGB-pixels) / pixel @ 30 fps and then group them together...

It would be 1102 MB/s read from the sensor ..

The 7D with it's two Digic4 processors can do 8 FPS @ 18 mpx @ 14 bit.
