AVIVideoStack image settings

franco

I stacked 11 AVI's of Jupiter then wanted to apply the same sharpening to all images. Every time I changed image it asked me to save the settings but then returned them to the default for the next image.
Can we have an apply settings to all button or perhaps not reset them when changing image.

My first animated gif of Jupiter. Pretty chuffed!

I see that you can set the settings for the first image then save all and apply the same settings to all the images. This pretty much does what I want. I think you can ignore this post, cheers.

[Edit] Actually there's still the line of white border pixels that seems to get staked in when the image shifts.
And what would also be great is if you could add the option to create an animated GIF from the image files. I'm currently using convert from ImageMagick - convert -loop 0 -delay 40 *.jpg jupter.gif

Marvelous!

johnpd thanks John. Shame about the strange stacking edge artifact, looks like a bug in ASIVideoStack.

One of these days when the weather cooperates I might get a chance to try my new ASI662MC, get some images of Jupiter, Saturn, and Mars while they are still visible, and use that new ASIAIR video stacking feature. I will compare it to other planet stacking software to see how good it is. I first need to find the focus point for the camera. It is easier to use the Moon for that, but that is getting tougher as the Moon moves into the morning sky.

johnpd a focus tool for planets would be great!

ASIStudio@ZWO

franco Do you mean software tool or hardware tool? Can you tell us more info about how to help focus? Thank you in advance!

franco

@ASIStudio@ZWO#59554 yes sorry, I meant a focus routine that helps you focus just like the one for stars.

Just realised this is ASIStudio, I was thinking of the ASIAir app.

SharpCap has a "Focus Assistance" for planets and surfaces. One of its options is to do a "contrast edge detection" where it measures the total contrast in an image. The higher the number, the better the focus. They have a couple of other options as well.

A long time ago I used a SBIG STV camera. It had a wonderful function on it called "Best Sharp" for use with planets. It would take an image, then a second image, compare the two using what they called a "Figure of Merit", and display the sharpest. It would continue to take images and compare the latest image to what it had determined was the sharpest. If the new one was sharper, that would then become the displayed image. This was great for public outreach as you could end up with a pretty good live planetary image.

I finally got out in the wee hours of Monday morning and was able to find focus for my new ASI662MC using my Explore Scientific ED127 refractor. I took a very short video of Jupiter, then used the ASIAIR Video Stacking feature. It worked pretty well. I did a 20ms 60sec video. I hope to try a little longer one now that I know where to start. The ASIAIR video stack did a decent job. I also tried the ASIVideoStack in ASIStudio. The biggest problem with that is that it generates a FITS file which is way overexposed and is difficult to work with. The .JPG that it generates is great. I don’t know why it cannot generate a corresponding FITS. Here is what the ASIAIR Video Stack gave me from the file it saved to my iPad Album to which I did some minor processing on the iPad.

Probably because the histogram has been auto stretched, hit reset and it looks normal.

Seeing is improving!

ASIStudio@ZWO

johnpd the fits and jpg files will both be saved in the folder of the video.

johnpd I don’t know why it cannot generate a corresponding FITS

If you are using FitsViewer, the auto stretch will be turned on in the histogram, so you will see an over-expose image, you can turn it off, and then you can see the normal image

johnpd It is nearly impossible to do because the file is so overexposed.

Did you try hitting the reset in the histogram? You can share the fit file with us and I can check if the image is over-exposed.

You can share the video with us, and we can check the 3 issue you mentioned.

johnpd

Beautiful shot. Unfortunately ASIVideoStack creates the FITS file immediately as part of the stack, so you have no chance to adjust it. The .JPG file it creates if you do a "Save" is pretty nice, but it has a Bayer pattern grid in it. Only the file written to my iPad is decent.

I want to process the FITS file in other software. It is nearly impossible to do because the file is so overexposed. I expressed this in another post. Here are some other issues with ASIVideoStack.

In addition to being very overexposed, the .FITS file has no color. If I use other software (such as AstroStakkert or AstroSurface) to stack the video, I get color.
I can get a less overexposed result if I use ASIFitsView to look at the stacked image and adjust or shut off the Histogram. But again no color is apparent even in any saved .TIFF images from ASIFitsView. The .JPG file saved to my iPad as part of the ASIAIR Video Stack process does have color. I have that image posted above.
It appears that ASIVideoStack is not recognizing the Bayer pattern in the .AVI video file. The .TXT file associated with the video file indicates a Bayer pattern of "RG" which seems strange. Other software though seems to recognize that.

I am using a new ASI662MC camera.

Just ran a test.

I can load a stacked fits file into ASIVideoStack and it looks normal.

The same file loaded into the fits viewer looks overexposed but when I click the reset on the histogram I get this.

It is in colour but not the same colour.

I checked your file on googledrive.

johnpd In addition to being very overexposed, the .FITS file has no color. If I use other software (such as AstroStakkert or AstroSurface) to stack the video, I get color.

Fits file does not have color, you need to debayer it. I think the other software you used automatically did the debayer for you, so you can see the colored image.

The image is debayered and saved as a jpg file so you can see the colored image.

Will convey this problem to the team.

If I load the .FITS file back into ASIVideoStack, I still get a basically monochrome image with a grid pattern as if it is not recognizing the Bayer pattern. I get a much better image from the .JPG version saved to my iPad in Video mode. I ran a short image tonight as it was extremely windy so I did not spend much time on it. I did some sharpening in Video mode and a little more with Topaz Sharpen. Here is that one.

This is what I got from ASIVideoStack.

ASIStudio@ZWO

franco FitsView has auto-white balance and Videostack does not have it.
So the display is different.

franco

johnpd the first image looks great.

Should Jupiter be blue or brownish?

I could see a grid in the image I loaded into the fits viewer, I checked the Bayer pattern and it was correct, ie RGGB.

ASIStudio@ZWO

Will feedback to the team and get back to you. Can you send the original fit file to us so we can check your image
