Append a still image respecting aspect ratio and possibly adding borders

I'm looking to append a still image to a video clip.
I found an old thread that deals with this issue.
Unfortunately I'm facing distortion problems and can't adapt the script.

Gavino mentioned at the time that this script should be improved...

Quote:
the photo is narrower than the video. When the photo is wider, you want to add borders on the top and bottom instead of the sides
Depending on the initial size of the video, the image is exaggeratedly distorted making its content unreadable.

Can someone show me the way because abstraction is not my strong point? (such scripts probably already exist)



Code:
v=DirectShowSource("F:\Vidéos\Enfants\Minuscule\gay-minus.avi")




pic="D:\pic\screenshot_395.png"
t=10 #[time in sec]
fc=Round(t*FrameRate(v)) #frame count

####################################################
# Option Zoom
d=20 # start zooming
n = 50 # no of frames for still
endzoom = 4.0
####################################################

ImageSource(pic).ConvertToRGB32()
AssumeFPS(v).Loop().Trim(0,fc-1)
#~ Animate(last, d, 119, "SimpleZoomBox", 1.0, 0, 0, endzoom, (endzoom * -0.10), (endzoom * 0.9))      # Option Zoom
AudioDub(BlankClip(v, length=t))
fv=last # frozen vid

vasr=float(v.Height)/float(v.Width) #video aspect ratio
pasr=float(fv.Height)/float(fv.Width) #picture aspect ratio
nW=INT(fv.Width*(pasr*vasr)) #new Width
xx=(v.Width-nW) #sum of the lateral borders
Spline36Resize(nW, v.Height).AddBorders(xx/2,0,xx/2,0)

#~ ConvertToYV12()

#~ v ++ last  #joining both clips
last #only for picture clip

Ok so basically if I got it right you want to append images of different sizes by respecting the Aspect Ratio and therefore have them resized automatically without distortion but by adding borders instead?

Well, that seems a pretty good job for Frosty Border!

Why not just do this in a video editor (NLE)? It would take just a few seconds ...

Thank you, three of you,

As you can see, this is my second post and I'm very beginner with avisynth.
This post is also an exercise to learn more about avisynth and try to improve an existing script. So I think I should have refrained from mentioning the existence of an already existing script.

FranceBB, I studied the FrostyBorder function but I don't think it's adapted to my needs : this function applies to a video while I'm trying to manipulate an image (then transformed it into a video).
Add vertical or horizontal black borders so that the generated image is the same size as the video clip.
You can even guess in my script that I want to zoom in this picture.

The StainlessS proposal is even more complex for me; I clearly don't yet have the knowledge for it.

Please be indulgent for my perhaps clumsy remarks. The script is almost working but I need your knowledge to make it really usable.

Well, once you use an image indexer in Avisynth like ImageSource or FFImageSource etc there's no "image" anymore, as every image is essentially going to be still video inside Avisynth of a certain number of frame, a certain length, a certain framerate and a certain aspect ratio. I noticed you're using AVSPmod, so you should notice that even with a simple "ImageSource" you see something in the bottom right part of the screen about resolution, frame rate, colorspace and bit depth.

Yes I know, that's what I was trying to explain, but let's do that step by step. Shall we? :P

Alright, I've collected four randomly chosen pictures from the internet at different aspect ratios and resolutions:

Image 1 - Margot Robbie

Image
Format : JPEG
Width : 500 pixels
Height : 500 pixels
Color space : YUV
Chroma subsampling : 4:2:0
Bit depth : 8 bits
Compression mode : Lossy
Stream size : 46.9 KiB (100%)
ColorSpace_ICC : RGB

Image 2 - Taylor Swift

Image
Format : JPEG
Width : 1 778 pixels
Height : 2 667 pixels
Color space : YUV

Now, first of all let's index them within our script. What I'm gonna use is ImageSource. The reason is that it will allow me to easily specify the number of frames that can be used and I suggest it over FFImageSource also because if you have .png files then FFImageSource will NOT work as it only indexes JPEG files and we don't know whether it will ever support other kind of images or not.
So, let's start:

Code:
ImageSource("margot-robbie.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
https://i.imgur.com/loSsmt7.png

As you can see, Margot ain't a picture anymore, it's now a video which lasts 1000 frames, has 25fps and is in 8bit RGB32.
Now, we have three more images, but to append them they gotta be the same as our final stream has to be consistent which means they gotta be at the same resolution, color space, framerate and bit depth, so how do we do that? Well, let's suppose that our output is 848x480 at 25fps. We can use FrostyBorder to make it happen:

Code:
ImageSource("margot-robbie.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)


As you can see, we now have a perfectly valid 848x480 4:2:0 planar 8bit (yv12) 16:9 1.77FF stream.
Let's do that with all the other images and then let's add them together, shall we?

Code:
clip=ImageSource("taylor-swift.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")

my_initial_width=clip.Width()
my_initial_heigth=clip.Height()
i_width = my_initial_width / 2 * 2
i_height = my_initial_heigth / 2 * 2

Spline64Resize(clip, i_width, i_height)

Converttoyv12()
FrostyBorders(848,480, frosty=true)
In this case we gotta use a clever trick to round the value to the closest even value 'cause the image has an odd resolution which most Avisynth filters can't handle, including TemporalSoften used by FrostyBorder, but for the rest, it's the same.



Code:
ImageSource("elsa-hosk.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)


and lastly our picture of a cat:

Code:
ImageSource("cat.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)


Ok, so now we're ready to append them together and get a 4000 frames 848x480, 25fps 4:2:0 planar 8bit video out of our images for our fictional actress/singer/model/animal advertising company doomed to fail xD

like so:

Code:
ImageSource("margot-robbie.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)
img1=last

clip=ImageSource("taylor-swift.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")

my_initial_width=clip.Width()
my_initial_heigth=clip.Height()
i_width = my_initial_width / 2 * 2
i_height = my_initial_heigth / 2 * 2

Spline64Resize(clip, i_width, i_height)

Converttoyv12()
FrostyBorders(848,480, frosty=true)
img2=last

ImageSource("elsa-hosk.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)
img3=last

ImageSource("cat.jpg", start=0, end=1000, fps=25, pixel_type="RGB32")
Converttoyv12()
FrostyBorders(848,480, frosty=true)
img4=last

img1++img2++img3++img4
And the final result is this crappy video: https://we.tl/t-qdWYrfD0E5

I hope this is clear enough to clarify your doubts.
Now I really gotta "go" to work (where "go" means stop scrolling doom9, shut down Windows XP, boot into Windows 10 here at home, and actually train a flipping object/people/setting/speech recognition AI which is exactly what I've been doing for months ever since they re-assigned me from the encoding department and I'm sick of it... T_T)

Thank you very much FranceBB for such a well-documented explanation.
Your post enlightened me on aspects of Avisynth that I had not assimilated well. It is now much clearer and I thank you for the explicit and very pleasant use of images, I confess.

I took my time and with a little trial and error I managed to get the result I wanted. In the end I preferred to use Imageborders because by zooming in on the edge of the image, Frostyborders let a black border appear, too different from the nice effect I expected (see attachment).


Finally, I want to thank raffriff42 for his simpleZoombox script that made my job so much easier and of course hello_hello for FrostyBorders.

So here's what I came up with:

Code:
v = dss2("(2020-04-07 09-00) L'heure des pros [CNEWS].ts", lavs="l3", lavd="l3", preroll=64)
a = DirectShowSource("(2020-04-07 09-00) L'heure des pros [CNEWS].ts", video=False)
AudioDub(v,a)
trim (1458, 1899)
LanczosResize(1280,720)
v=last

pic="D:\pic\screenshot_395.png"
t=5 #[time in sec]
fc=Round(t*FrameRate(v)) #frame count

# Option Zoom
endzoom = 2.0

ImageSource(pic, pixel_type="RGB32")
Converttoyv12()
ImageBorders(Width(v),height(v))

AssumeFPS(v).Loop().Trim(0,fc-1)
ConvertToRGB32()
Animate(last, 
\         1, 
\         119, 
\         "SimpleZoomBox", 
\         1.0, 0, 0, 
\         endzoom, (endzoom * 0.10), (endzoom * 0.9))
AudioDub(BlankClip(v, length=t))


ConvertToYV12()
v ++ last  #joining both clips
#~ last #only for picture clip
