Could you possibly consider enhancing the handling of the zoom preset parameter?

1. The Parameter actually decreases in value as the zoom increases and the value seems to have no relation to actual zoom percentage shown on the GUI when the i / o zoom option is used
2. The parameter is required to be an integer, which does not allow for sufficient granularity in the sizing of the image.
In other words, using a parameter of 74 produces an excessive zoom amount for a 2.40:1 image cutting off part of the image area, while 75 leaves visible black bars
3. For some obscure reason, a value of 80 doesn't seem to give a valid zoom. (Not sure about this one as I haven't tested it recently.)

So, while the function is there, it certainly could do with some enhancements.

For now, I am certainly happy to have the capability, but I almost always have to use the i / o keys to fine tune the image size to establish the exact zoom amount to completely eliminate the black bars without eliminating an excessive amount of the image.

Thanks in advance for any consideration.

Movieman:
I am using this as a reference for sizing, rather than depending on individual titles which may not be exact.

Movieman:
Bump, please.

Am i making an invalid assumption that the 28038 command for the video engine zoom is a part of JRiver Media Center?

If it is, I would appreciate an acknowledgement on whether or not anything can be done to improve this function per my above request.

Should I have posted it on a different section of the forum?

Thanks, Vern

That looks like MC command.

I recall you had some discussion about this, but I dont remember what it was about ... are you trying to use anamorphic lens? ... or is there another reason why you zooming in? (sorry I cannot truly remember your set up)

Movieman:
Yes, anamorphic lens + Constant image height 2:65:1 screen. Zoom is working for me and using MadVR to set the proper anamorphic lens correction is working fine.

The I/O keyboard function is working fine. The problem comes when trying to assign a zoom value using, for example:

<Entry Key="Alt;H" Command="28038" Param="74" /> 

A value of 74 for the parameter results in too much zoom, a value of 75 results in too little zoom. Since the parameter only accepts an integer, it is impossible to set zoom accurately using using the command.

The 28038 parameter field would need to be changed to accept a decimal value like 73.67.

Using the I/O hot keys on the keyboard allows me to accurately zoom after the fact, but I really prefer that the presets deliver the same granularity as the I/O function does.

Also, from a purely logical point of view, why does a decrease in the parameter from 100 at no zoom to 74 represent an increased zoom. I can live with that, it just seems counter-intuitive.

Let me know if you need any more info.

Thanks....
