Squeeze Mode on DVX 100B
So is there a significant loss in res compared to the anamorphic adapter? I read the DVX Book by Mr. Barry Green and it was very helpful. I do remember him saying it was a res loss but I’m just curious if it is that noticeable.
I doubt that I am going to blow my Indi Feature up to film but I want to shoot it and have the option to blow it up if I changed my mind later. Any thoughts or comments would be greatly appreciated. Thanks. Brian |

So then should I shoot in letterbox and then crop the black bars then edit in 16:9?

The resolution loss in Squeeze, vs. the hassles avoided from not having to use the anamorphic adapter, are a pretty even match.
Squeeze Mode does involve a res loss, bringing your ultimate resolution down to about 360 lines (when shooting 24p/thin). With the anamorphic adapter you could get almost 1/3 more resolution. However, the anamorphic introduces so many compromises into the shooting equation that many people don't bother with it, and just choose squeeze instead. While squeeze involves a res loss, keep in mind that it brings the overall resolution down to basically where interlaced "native 16:9" cameras end up. Those cameras have a max. of 360 lines as well, because they're interlaced. (I would say don't use squeeze if you're shooting interlaced, because then it'll drop you down to around 270 lines!) In short, I find Squeeze acceptable for most purposes. |

dont forget, what were calling a "loss in resolution" isnt actually a degredation of resolution.. its a digital cropping and then vertical stretching of the footage... in the end what youre really "losing is the top and bottom of the frame
one ting i wan to know though, is whether Pana have set the DVX10b to tag 16:9/squeeze mode footage? or do u have to set the aspect manually like the 100a?? anyone wana buy a DVX100 original?? LOL less than 250hrs on the clock.. lol |

So when shooting squeeze mode, will it fill a widescreen tv the same way a native 16:9 would? Or will there be lines at the top and bottom?
What about the outside chance of a video going to film? Is squeeze a problem? |

DVC80 + 16:9 adapter or DVX100
I shoot with a DVC80 and GS120. I really like the anamorphic 16:9 mode (SLIM) in the GS120 and want to be able to match it with my primary camera, the DVC80. If the Panasonic AG-LA7200 Anamorphic Lens Adapter does such a lousy job, why is it so expensive? Am I better off paying $750 for the AG-LA7200, or just selling my DVC80 and paying the difference for a used DVX100/A? I'm guessing the cost will be about the same either way. 24p isn't very important to me, so the main advantage of the DVX with 16:9 squeeze is that it would be a lighter, shorter rig (plus the other step-up features of the 100). Did I just answer my own question?
Which DVX100 -- original DVX or DVX100A -- has the better low-light performance? (I often shoot weddings and stage productions, so this is important.) |

Tim, the adapter isnt "bad" its jsut a lil awkward to work with.. especially if your taking teh adapter on and off periodically, the mount itself is ok, but the thread is cheap arsed plastic which will soon wear off and be useless. I returned 2 adapters for this reason. The lens is fine and makes the DVX a kickarse 16:9 camera, considering the native wideangle on the leica on its own..
moving along.. with regard to low light performance, the 100 original release is far cleaner by a country mile than what the 100a ever could be. running both side by side, you can see the differences and periosidically one must check exposure levels to match, what might be f2.8 on the 100a, would be f4 on the 100, now this is al dependant on the lit environment. Its not THAT noticable, but crank the gain and you CAN tell teh difference.. one thing though, in reply to the low light noisiness of teh 100a, i find that the 100a has a richer colour and wider dynamic range than the 100 (irrespective of the scene setting configs) .. ive even dumbed down my 100a to match the 100and still the colours are just that little bit deeper. |

I'd say go squeeze. If you're shooting 24p/thin, you'll get just as much 16:9 resolution out of squeeze mode as an interlaced "native 16:9" camera can deliver. |

Barry you probably have been ask this, but how is the stardard DV on the HVX?
But for me the HVX200 is a ways off. I've got about $3,000 now. To get the HVX200 and all that goes with it is way out of what I can do right now. The best I can do is the DVX or wait alittle longer and see what Canon comes out with. |

Barry:
Is there a resolution loss shooting with the 16 X 9 bars in letterbox on the 100b?

Standard DV on the HVX looks fantastic -- in 16:9 it's native 16:9 full-resolution, and in 4:3 it looks about the same as the DVX.
When going to letterbox there's no resolution loss at all, because you're still displaying 4:3 video, just covering up some of the screen. So the area between the letterbox bars is resolving exactly the same as it would have in fullscreen 4:3 mode. Actually, in letterbox it's a little bit cleaner, because the compression is more efficient due to the repetition in the letterbox bars. |

Music to my eyes, Barry. I'm still waiting for your book and DVD (along with my Panasonic rebate check). Can't wait to dive in head first.
Look here, too! http://www.dvinfo.net/conf/showthread.php?t=60750 (Sorry for my redundancy. I am middle aged and my synapses just don't fire like they used to) Thanks!
