you might want to consider the new Canon 7D, i am.

this movie about it tells a little bit about history and features,
while being a bit funny at the same time ;)

Hi erikals,

I agree that DSLR's (including the Canon 7D) are very interesting...but there are some things to know and consider.

1) The Canon's only record in low profile AVCHD (8 bit - 4:2:0)
2) The longest clip can only be 4 gigs in size...about 10-11 minutes long
3) The Actual sampling from the chip is much lower resolution than HD due to aliasing issues (its a short fix but you loose definition and resolution)
4) Due to using a Cmos sensor there are rolling shutter issues.

Check out this blog from a very creative director and FX super I know...who used to run the Orphanage.

There are many other issue in regards to DSLR's if you are willing to understand them and deal with them...then this might be a solution for you.
They are not going to be RED killers, or even replace existing video related camcorders due to the issues involved.

Hopefully Canon and others will address the issues and make them a real pro product...but at this time...they are just interesting and limited.

Also note that there are pulling focus issues without additonal gear...and there is no video like zoom lense at this time. Though you do have an array of primes and still lenses to choose from...but no autmatic exposure or focus work on the video section.

So think of anything you shoot...is more like shooting with film...thus measure and set target focus areas. This will save you a lot of headaches.

Don't think of shooting with a DSLR as video...think of it as shooting with film...

Also note that you will need a seperate audio solution to record seperately or connect into the DSLR...

There is no timecode on DSLRs so that will impact conforming as well.

Good luck, and check out all your options...there isn't just one.

ouch, that rolling shutter issue is quite bad :\

a fix, must be done in post though,...

what looks the most interesting to me about the DSLR cams from Canon is that they can shoot using quite low lighting and still get a good result.

with a good lens it could probably be even further improved...?

of course at the other end of the price range is the KodakZi8...that's 1080p 30fps, 720p 60fps and 30fps and for the cash is great...i have one!

...the $180 KodakZi8, was considering getting that for my mam, (no kidding) http://forums.cgsociety.org/images/smilies/smile.gif

btw, interesting read on editing AVCHD,

zi8 footage i shot



12-28-2009, 07:32 AM
and quick green screen test


my main reasons for getting the Zi8 were
1.low cost
2.keyable footage
3.no tapes!
5.tiny, simple to use and good results
6.separate mic input

it's very impressive compared to the low price,
still, i need more quality,...

i might drop the Canon 7D though, just go for the Canon 500D instead,
(which is half price)

for shooting commercials in 720p the Canon 500D should be great (i hope...)

the biggest drawback right now is that i need something to stabilize the movements of the camera.
put on a weight?
make some sort of home made stabilizer?
suggestions on that one? http://forums.cgsociety.org/images/smilies/smile.gif

Just a friendly reminder...that DSLR do not do auto focus when in Video mode...so to do a steadi cam with it...is not a good use for it at this time.
you will also need a pull focus knob of some kind to help get your shots.

Check out:


There are others...but these guys know their stuff.

Hi Pagnozzi,

I agree with you as to focus issues...just that the Canon 7D needs to have to add a pull focus control...and if you want to setup some kind of steadi cam...then you'll need some kind of remote focus control...otherwise you'll have issues.

At this time the 500D is not as well suited as the 7D for production work.

So it isn't simply getting a camera...there are other optiosn and needs that you will have to address to get it properly production ready.

that's true,
not sure why, just looks different as far as how the levels operate...

found this interesting btw, "steadytracker"
a pretty good way to stabilize footage

interesting comparison between Red and Film,
