(pics) 16:9 Compression Tests - interesting results!

The DV3000 is a unique camera to say the least but like Rob mentions mileage will vary with other cams. Most cams do not offer a Digital Wide Mode which to me appears to be similar to newer cams that offer a wider angle of view in 16:9 mode. The Digital Wide mode goes a step farther and also lets you enjoy the increased real estate for 4:3. At least thats the way I see it.

With the newer cams that shoot quality 16:9 (DV953, PDX10, GS100) it makes sense to leave them in this mode to take advantage of the little to no resolution loss 16:9 mode vs. 4:3 with post 16:9 cropping.

The DV3000 of course has the unique non-interlaced effect while in Digital Wide mode and that is even more of a reason to shoot 4:3 and crop 16:9 in post as I'm pretty sure that its digital squeeze mode does not have the same effect.

Yeah, that's the problem with what happened with this thread. I didn't intend it to become a debate between the modes on the camera, but instead was curious as to whether applying in camera bars would result in less artifacting, or if the "shoot and protect" (or that given name for shooting for 16:9 and cropping in post) gave equal results.

No debate, but the Digital Wide mode plays a major part in your post 16:9 crop and others need to know why this may not hold true for their non-JVC cam.

Right...crap! sorry!!!!! I misunderstood the reason. Thanks a ton! So, what do you think then? The difference between d.wide regular and d.wide with my title? I hate the screwed up colours, I guess those would qualify as artifacts...but do you think it makes much of a difference?

Thanks again Tommy, THANKS!
