Yep $850 US... thanks for the info.... I will see if one of the local TV stations has one that I can use.

I don't have to match the camera to anything so i don't have that problem. I would just like to see a good scene setting for the 320 but if you can work from the 350 scene settings, thats a good start. There isn't a lot of response to the original question, wonder why. Thank you. |
Re: scene settings for pmw 320?
Detail level or Crispening, which one of these setting will give a PMW320 a bit more sharpness to the image?

Re: scene settings for pmw 320?
You might want to take a look at my guide to picture profiles and scene files. Within the main page you'll find links to more in depth information which should give you an idea of exactly what the key settings do.
Picture Profile Guide. | XDCAM-USER.COM Detail is the main control, crisping is a subset of detail, so if you have no detail enhancement, crispening will do nothing, but if you have a lot of detail enhancement, then crispening will modify the detail settings. |

A positive detail value will increase the contrast around edges which will make the picture appear sharper but at the expense of un-natural "video like" edges around things and noise becoming more visible. The actual resolution does not change. A positive Aperture value will make the 320 look sharper but without the blocky edges.
You should try setting the EX to Cinegamma 1 and the 320 to Hypergamma 4 as these are the same gamma curves. When comparing sharpness you have to remember that perceived image sharpness is primarily a function of contrast with resolution being secondary. So unless you first get the contrast range to match through matching gamma curves and gain, any changes to the detail settings or aperture are only masking the contrast difference, so you'll never get the cameras to match. |

In my engineering days the conclusion we came to was that it was best set as low as possible. Increasing it can reduce noise - but very adversely affect the picture otherwise. Don't be tempted into just thinking of it as a noise reduction knob. On some pictures that's all it may seem to do - on others it can have a more definite (and undesirable) effect. Quite a good explanation here: http://www.panavision.co.uk/pdf/down...oting-tips.pdf and look closely at the diagrams. In brief, it means that detail enhancing is only given to quite distinct edges, and not to small changes (such as noise). Nice idea in principle - but it can't distinguish between noise and subtle detail. Therefore as it gets increased, high contrast detail is unchanged, subtle detail is lost. That can look really bad, since typically such as a face can still be sharply outlined, but lack all the skin texture and become "puddingy". If you look at the diagram next to "Technical Information" then what it actually does is vary the distance between the red lines - more crispening means moving the red lines further apart. hence the more descriptive term of "coring" - it removes the "core" of the detail signal. |
How to keep scene files from resetting on power down
I have 4 great files set up by engineering department at Band Pro. The 1st is named Normal and if I am on 2, 3 or 4 when I power the camera down it defaults back to the Normal file. Is there a setting in the menu where I can stop this from happening? Thought I would ask here first before checking back with them.
Thanks |
Re: scene settings for pmw 320?
Apparently it is the memory retention battery gone dead per engineering. Doesn't affect the memory for the scene files themselves though. That is a different setup. Now I have to see if it's user accessible or need to take it back in.
