HPX370 in Standard Definition


I currently have a Panasonic HPX370 on loan from a friend of mine. I am very happy with the camera so far and I may purchase it, however there are a few questions I have that may or may not be specific to the this camera, but as this is my first professional style camera I do have a few questions.

I notice that when doing Standard definition over SDI, that it is much more soft than a standard definition camera with SDI out. Are their any recommended settings for SD-SDI that can help make the picture stand out more? It is in focus and colours are fine, however it just doesn't look as good as other standard def cameras that I have used. Also, when I am zoomed in on a subject, the chroma is very vibrant, however if I am zoomed out all the way, the chroma is not as strong. I understand that lighting would affect this, however, is there a feature in the camera that can help keep the chroma level stable? I know I could boost the chroma level, however it would be too strong when I zoom in, unless there are other adjustments that can help.

I understand there are a lot of features on this camera. I just wanted to know if these are issues to this camera, or to all cameras, and if so how to compensate for them.

Re: HPX370 in Standard Definition

I don't know about in-camera settings but I can tell you this: when you're acquiring SD from an natively HD camera the results are usually going to be sub-par. Why? Because the camera first creates an 1080p (or i) image and then it down converts the image internally in real time to SD. This internal in-camera down conversion is never good. If you want good SD from the HPX370 record 1080p and then down convert to SD in post!
