Canon HV20 "jello effect"

This video clearly shows Canon's HV20 "jello effect" caused by vibration. Some claim it is caused by the rolling shutter while others claim it is caused by the optical image stabilization.

How you get that jello effect?

Problems with HV20?

[vqflores]

Use a Canon HV20 camera and add vibration. That's all it takes. Something in the camera design does the jello effect. If it was slower and smoother it would be cool, but it isn't.

erm, you're an idiot! He wants to demonstrate the "jello" effect!

It's about the cmos sensor.

HOW IN THE WORLD DO YOU PUT HV20 VIDEOS ON THE COMPUTER?!?!

i seems like in the water....

@vqflores Yeah, this video was taken a long while ago. We've come to see with the influx of budget hd camcorders and cellphone video recording, that this is definitely 'image stabilization' at work. Interesting video example, its too bad this 'jello effect' is so common nowadays

This particular jello effect looks like heat distortion.

yo he filmado con mi camara hv30 en un tren varios kilometros,,,de camino...en la sierra....y no se nota nada de esto!!!!

Physics done broke!

Just for yuks...would love to see different cameras for a true comparison. One of those cameras should be a CCD chip camera. Also...maybe an SD but with a 16:9 format (to match the HD).

i dont see how hv20 footage can be this shitty?

@vqflores

Sensor scanning speed. Progressive CMOS sensors generally scan photosites from top corner, down the top row, down to the next row of photosites until the last one is exposed. Between the time where the first photosite and the last photosite on the sensor is exposed, the subject you're filming may have moved (or in this case, the camera's position has moved). If this scanning of the sensor's rows goes too slowly, you get this rolling-shutter effect, Jello-effect, skew, wobble, etc.

this is why ccd owns cmos.
