If you plug the century .7x wa on a DVX what aspect ratio are you shooting in?

If you want 16:9 footage with the dvx100a, are the only options, shooting letterbox, shooting squeeze, or buying the panny anamorphic that has the focusing problems?

thanks a lot for any info
 
after searching around some more im pretty sure it shoot 4:3 so for 16:9 you would need to crop in post, correct? that would lower your resolution so can anyone comment on how that might look compared to something shot in squeeze mode?
 
With the century .7 wide angle adapter your you are still shooting in a 4:3 aspect ratio since the DVX only has 4:3 chips. Squeeze mode shoots in a reduced vertical definition mode but makes the image look normal in a 4:3 monitor (EVS or LDC) Anamorphic produces the most vertical resolution as compared to squeeze since it only changes the image in horizontal resolution.

You are correct that video shot with the anamorpic adapter or the in camera squeeze mode will look distorted on 4:3 display (TV, external monitior) but not footage shot with the.7 wide angle adapter as it is not anamorphic. My prior post was refering to the fact that in squeeze mode the DVX100b displays undistorted video in the EVS or the onboard LCD.

The anamorphic adapter provides the highest vertical resolution for producing 16:9. Squeeze and letter box reduce the vertical resolution to create 16:9 and the .7 wideangle adapter adds a slight barrel distortion to increase the viewing angle but the video remains 4:3.

The other option would be to shoot in normal 4:3 mode, but apply a 16:9 letterbox matte in your editing program. This really gives you the best of both worlds.

After applying the matte, you can use "motion" in your editing program to reposition the clip for best widescreen composition.

That's not entirely true. I'm not sure about the DVX (I don't own one yet), but when you shoot in squeeze, as long as it sets the flag for widescreen in the signal (which it must I would think), it's more a function of your TV. Old TVs won't have any clue what the flag is saying, will ignore it, and will play distorted. HOWEVER, many new 4:3 TVs, that are halfway decent at least, will letterbox it for you on-the-fly (just like pretty much every DVD player on the market will do). So really, it depends on your TV.
 
Tainted:

Its true that new LCD and Plasma TV's have multi-mode options that alter the video to fit the aspect ratio as well as some of the latest CRT's. But any altering comes at the expense of image quality. The discussion here is if he wants 16:9 video either using squeeze mode or anamorphic I assume he intends to play it on a 16:9 TV so as to preserve maximum image quality.


Also the DVX 100b has the ability to create 16:9 aspect video on native 4:3 chips using a feature called squeeze mode. In older models of the DVX the video looked distorted in the EVS or LCD. The new camera displays the video undistorted in the LCD or EVS but records it at the 16:9 aspect at the expense of vertical resolution. I am not sure that any TV automatically detects the aspect ratio unless you record to a DVD and then the DVD player detects the type of format that was recorded, i.e. progressive or interlaced and 4:3 or 16:9.


We are really discussing the capture process here and the features of the DVX. In fact in programs like Premire and FCP the video would still be detected as 4:3 since the camera only has 4:3 chips. The Squeeze mode and the anamorphic adapter create 16:9 and modify the image by trimming the verticle resolution but the flag is still 4:3
