can someone crack open the dvx100 and rotate the CCD block?? at DVinfo.net

Obin Olson · January 24th, 2005, 08:11 PM

Ok so we have this huge issue of the images from GG adaptors being flipped. to un-flip the images requires a 2nd gen. of compression and a loss of image quality not to mention the PAIN of RENDERING AND shooting like that..can someone tear down a dvx100 and see if the ccd block can be rotated 180 degrees so that we would see the images right-side-up??? anyone? It seems to me this could be done...Juan?

Sounds dangerous! That's a lot of money on the line!

I see no reason there has to be a generation loss in the image flipping. Just render out to an uncompressed codec. That's the best way to work anyway :D.

Obin Olson · January 24th, 2005, 10:19 PM

it's a pain and I work with DV in a number of projects so uncompressed would not be a good option. I don't see why this can't be done. Juan has torn apart the dvx100 I bet he could answer this question better then anyone.

Aaron Shaw · January 24th, 2005, 10:23 PM

Excellent point!

I'm not sure I have the guts to tear my DVX apart!

well, suppodsely you can flip a DV stream without recompressing it.I just don't know which "open source project" supports that.
Same happens with Mjpeg and Jpeg, you can rotate and flip them without needing to recompress.
If you don't believe me look at the MJPEG Tools open source project.....
My two cents.

Well, if one of you guys has a handle on how this is accomplished, please share any info you have, including weblinks. I'm ignorant and unwilling to mutilate my XL2.

I'm working on an inline circuit that will rotate the image coming out of the video port of the camera. It will also be able to add framing lines/boxes to the signal.

This won't help your editing problem though. I won't be taking my dvx apart anytime soon...

Flipping the DV stream sounds interesting though... Someone should tell those dudes over at dvrack to add that setting...

Obin Olson · January 25th, 2005, 06:33 AM

someone needs to get on the ball and write a little code to make this happen for editors like Adobe premiere FCP VEGAS and more..I bet a few $$ would flow in the direction of anyone willing to take this on..I sure know a few $$ from my company would be worth the price of the software if and when someone writes some code

Could be difficult to re-ajust the 3 ccds after the 180° rotation.

Aaron Shaw · January 25th, 2005, 01:04 PM

Mm yes, excellent point. It could be very difficult unless all three belonged to a single mount that could be rotated.

James Hurd · January 25th, 2005, 01:25 PM

Maybe another point. Wouldn't you like to use the camera without an adapter?

Aaron Shaw · January 25th, 2005, 01:26 PM

What do you mean?

Obin Olson · January 25th, 2005, 06:45 PM

ok so what got me thinking is the Sony HDV cam has the 3 ccds mounted on a SINLGE bracket..would it not make sense that the dvx1oo is the same? can someone tell me if this is so?
