Display stretch vs Histogram in Sequencer and Filenames questions

#1

Post by rockenrock »

Hi Robin,
I want to confirm a couple of Sequencer Commands:
1. Is this correct?:
The Reset display stretch command, only affects the appearance, ie brightness of the displayed image.
Does that mean the saved file, ie livestack, is unaffected no matter the actual display stretch settings?

2. Is this correct?:
The livestacking histogram settings (autostretch, manual stretch) affects the image data saved to file.
Is there a way to reset the livestacking histogram within a sequence?

3. In Sequencer I see this command:
Arrange file and folder names to keep sequence captures together.
Is this affecting any setting in File/SharpCap Settings/Filenames?

4. In File/SharpCap Settings/Filenames:
Is the below the way to add the time stamp to the unprocessed livestack filename?:
I have selected Edit filenames manually, and then added {Time} like this....
\{AutoSave}\Stack_{BitDepth}bits_{StackedFrames}frames_{TotalExposure}_{Time}

5. In Camera Control panel - Image Controls I see:
Timestamp Frames On/Off. Does this put a visible time stamp into the actual image?

Thanks,
Roger

Hi Roger,

let's see...

1. Yes, that's correct - the display stretch only affects the screen image, so live stack saved files are unaffected (unless you choose 'save exactly as seen' as the save option, since the job of that option is to save the exact image you are looking at).

2. There is a 'Live stacking reset stretch' step in the sequencer, in the processing section. You can also use the search box above the list of available steps to help find steps you are looking for

3. It doesn't affect the settings, but during that sequence, the settings will be overriden in a way that puts all of the captures from the sequence in a top level folder, with sub folders like '#4 - capture of 30 light frames', this indicates capture number 4 of the sequence and gives you an indication of what was being captured. Within those folders, file names as specified in the settings are used with minimal modifications.

4. I would suggest using {FrameTime} not {Time}. The Time tag is the time the capture as a whole started, while FrameTime is substituted with the time of the actual frame in question

5. Yes, this will add the timestamp into the corner of the image. Useful in some cases.

cheers,

Robin
