CMOS vs 3CCD Heavy Vibration Test

[ez2curanut]

I have a canon SD780-CCD, and just bought the Canon SX230-CMOS... I WILL be returning the SX230-CMOS to walmart for a REFUND. Anyone own a decent SD780 they want to sell? :) Not from watching this video, but from recording inside my truck with cmos, and the beautiful clouds are ALL jiggly like :(

[AndJorD]

thank you very much for this video, help me a lot to understand a huge difference between ccd and cmos

[overexposurevideo]

yes cmos rolling shutter is a nightmare with vibrations, nice test

[toonberry]

very informative.  thanks man!

[vwlover94]

Cmos sensors are nice in a way that they block out the overexposure light streaks , and CCD's are great also in almost everything, but the CCD's do tend to sometimes have light streaks across the image in video. :( well im going to get the panasonic lumix dmc fz100 anyways see whats happens :( , but i mean the camera does have image stabalization with 3 mode options, so what ever ill post a video with the camera in a week or so :)

[superchargewhine]

@vwlover94 I actually like the vertical line smear the CCD gives off....

[vwlover94]

@superchargewhine really? i hate them because I film short films with a ccd camera and it sucks to be able to see the huge "Light Sabers" from strong light get in my way of sun shots, or shots of stron light?? :P

[zenmachinefilms]

This is beyond even the Foundry's plugin to fix.

[echelecopao]

It would be interesting to see the results after running Deshaker (virtualdub) on both clips.

[mikosoft]

@echelecopao Deshaker won't help anything with jello effect. Deshaker works on full frames while jello effect affects parts of the frame. If you wanna know more search for "rolling shutter effect".

[shdwsclan2]

Also those looking 1080P, there is a trick with 1080i cameras. If the camera can capture 1080/60i, then a pulldown to 30/24 in post would give you 1080p. The camera (xh a1s) cant capture 1080p directly to tape, unfortunately, but can output using the SDI ports on the g series or using the pulldown method in post....

[shdwsclan2]

CCDs have global shutters, while CMOS systems have rolling shutters.

Im planning to buy a canon XH A1s instead of a XF300 for this reason.

[Soundfx4]

...well this changes my view on CMOS...but I suppose it matters not if the camera won't be moving at all :\ luckily what I'll be shooting with the AG-HPX300 will not involve any movement...it's still disappointing, I thought I had found the perfect camera.

[sopues]

@Soundfx4 if it involves no movement it will be a pretty boring film, no? ;)

[Soundfx4]

@sopues haha, you have an excellent point :P

[Pok3rF4ce]

cool comparison, thanks

[CybaGirl]

Can someone please explain to me why the Gppro's HD Motorsports HERO does not suffer from this rolling shutter and jellyfish effect?

Because it uses a CMOS sensor and the following sensor information was taken from the specifications page.

Sensor Type: 1/2.5" HD CMOS, 2.2µm-sized pixels

There website is located here.

Remove all the spaces.

[sohcsarewicked]

I posted a video of hv30 it was such a waste of film. I Thought my camera was something wrong but I see your explaination thanks....so dissapointed

[spyd4r]

i'll try that next summer.

[formaset]

I forgot to mention... I receive dozens of cameras for repair because of this.

[formaset]

Dude. Regardless if your cam is CMOS or CCD, you will damage the drum heads with this excessibe vibration. It's just not made for this. you will disalign the capstain and heads.

[spyd4r]

good point.

[jxdigital]

Drum heads?? That's history! The HDC-SD5 records on memory cards, as a lot of modern cameras do.

[formaset]

The man mentioned 2 cameras. One of them being the Canon HV-20. Pay attention before trying to teach people. I know every camera in the market. no need to teach me.

[jxdigital]

Formaset: Couldn't know that you knew every camera in the market. Wasn't meant offensive...

[formaset]

None taken...

[Macsgrafs]

@formaset there is NO capstan...the panasonic is digital in that it records direct to smart media card

[seanski44]

@formaset except that the sd5 is solid state and records to memory card. so no moving parts to worry about. Can't speak for the canon as I don't know it.

[Klingl3r]

Wow. CMOS really sucks. I really don´t understand why the manufacturers now use mainly CMOS sensors and not CCD. Even Panasonic is using now 3CMOS instead of 3CCD.

[vantagetes]

CMOS has better power consumption and is immune to bright light artifacts you get with CCD. CMOS with a global shutter (vs rolling like they use now) fixes the jello issue however it's a lot more expensive and aren't implimented into camcorders yet.

[Klingl3r]

Yes, CMOs may have some advantages, I have an DSLR with CMOS-sensor and it has some advantages when doing a long-time exposure.

However, for video I prefer CCD because with the actual CMOS-cameras it isn´t possible to get a good vid of moving subjects.

So overall the disadvantages outweigh the advantages.

Power consumption shouldn´t be the problem in times where you can get a 3rd party battery for 10 €.

[vantagetes]

Well it all depends on your application! CMOS is fine for moving subjects (subject moves but the camera doesnt), just not for applications where the camera itself it subject to movement (IE this video where the camera is being shaken by the boat motor).

There is also what's called a CMOS global shutter which solves the "jello" issue however it's fairly expensive and would put the price of a "consumer" handycam back up into the "pro" price range with limited battery life.

[Klingl3r]

Well, that´s the problem. As long as CMOS-cameras suffer from the rolling shutter and jellyfish I won´t buy one for video.

I often pan and move during video and also do some vids on board of moving vehicles.

Manufacturers shouldn´t have released CMOS-based cameras as long as the global shutter is too expensive. So it comes that even a cheap 150 $/€ camera with CCD has a big advantage over some expensive CMOS cams like Canon HVx0 or Sony HC series.

[rogs60]

You are joking?! --for this kind of shooting, CMOS sensors with rolling shutters are just rubbish.

For everyday 'family ' footage,I'm sure they're fine.

Any vibration or rapid pans, and they just fall apart.

[Visualbrother]

yeah 35mm is so much like a rolling shuttter, reading pixel lines and all that...

[noreflection]

what did you use to keep any water spray off the camera or anything?

[spyd4r]

this was mounted on top of a wakeboard tower, water wasn't near the camera.

[raynvideos]

I also have a Canon HD camera and get the same rolling shutter. But I also cant seem to upload HD in the native m2ts files. What are you using to store the videos for uploading into youtube?

[spyd4r]

I import straight from the Camera into iMovie 09 on my Mac Book Pro. Then Export using the HD size option which is 1280z720..

[kcrig]

Great test! I was just reading how the Cmos is so much better than 3ccd...it has its place but not everywhere.
