When I get my own Canon 7D I will put up more samples.

Hey all,

i have a problem,

i just bought a 7d, and i love it! but, it only shoots 50p, not 60p, but its ok and i cant find a way to make smooth slow mo. i have FCE 4.0.1, and i've tried to download twixtor plugins, but they dont work (it says twixtor failed to render). is there a way i can make decent slow motion? when i slow it down using the 'speed' setting, it jerks and becomes unsmooth. and i dont want to use frame blending because it doesnt look good.

i'd appreciate any help at all.

thanks

@mimisico0417

Do you have After effects? You will only get really good slow motion with twixtor (there are a couple other plugins too cant think of them at the moment) but they work best in AE, you would not want to use twixtor inside any NLE due to the slow render speed

@mimisico0417

7D will shoot 60p if you switch it to NTSC mode.

Can anyone tell me if the 7D (or the 5D) uses 8 or 10 bits quantization ? What about the compression ? Is it MJPG200 or AVCHD ? Can you output HDSDI ?

Thank you

[eyepatchentertainmen]

8 bit, compression is h.264 at 54-57mb. You can record the HDMI output, but it is not full 1080p resolution. Image reocrded by canon 7D and 5d is taken from binned pixels from the sensor meaning the image has artifacts such as moire and aliasing. In other ways the image is more pleasant than what you would get out of a Sony EX series cam

[eyepatchentertainmen]

Lets clear this up. The 7D shoots 720/60p max. The frames were interpolated out to 240fps with twixtor. This video was shot with one of the slower shutter speeds, so if I showed the waves crashing, you would have seen a weird blur. Because of this, I limited it to just waves in the ocean. Shutter speed is related because when you interpolate down to slower speeds a faster shutter will preserve more frame detail. In a cinematic sense, a motion picture camera would shoot at an equivalent of 1/500

[eyepatchentertainmen]

(continued) for a scene shot at 240fps to maintain a 180 degree shutter angle which would give the same motion blur as 1/50 (1/48 in actuality). Additionally this scene was upconverted to 1080p and then downsampled again after going through a color correction process that helps remove the jagged edges.

is that video not showing the views for anyone else?

@Rudde47 it is done on the computer after. originally it was captured 720p 60fps i believe

HEY I KNOW WHERE THAT IS :D that's uhh near bar harbor in acadia park i think. thats like a huge thunder gyser thing where the water splashes!! haha sweet footage

get your moms huge cock out of your ass before you start talking mother fucker

[soneeqboom]

@007Fortis nice call dude...does it come in good? HAHAHAHAHAHA from cameras to terrorist LOL should tell them how to go from 60p to 24p and slow mo the bomb yeah dude KEwLLLLLL HAHAHAHA

[007Fortis]

@soneeqboom Well who knows, terrorists like you (Soneeqboom) like to steal shit and take it apart and make bombs. you fuckers can't be trusted.

[soneeqboom]

@007Fortis can i take the shop assistant to the desert also to help me shoot some cactus? LOL nooooo wayyyy r u serious...camera shops actually have places to have lessonsss....wow that's something new ohhh DURRRRRR LOL and why would they sell stolen goods in the desert....that's kinda weird....who'd wanna meet in the desert seriously to sell stolen goods unless its a stolen camel LOL
