Add individual frames on avisynth

[sirt]

Hi,

This subject has probably been covered but I didn't manage to find something easy to understand, so here are my questions :

1) Let's say I have three frames 1.jpg, 2.jpg, 3.jpg with identical properties. How could I join them one by one by using AVIsynth ? Let's say I want 1 as the input frame, then 2 and finally 3. Howhever, I would need to recompress this AVS file then, wouldn't I ? Or is there a way to mux those individual frames together and create a video stream without reencoding ?

2) Same question but with different frames : 1 would have a different size than 2 for example.

avisynth frameserves uncompressed video, so unless you want to leave it as uncompressed video, you have to re-encode with something

You can use ImageSource() to string together an image sequence

You cannot use different sized frames (assuming you meant dimensions)

Okay thanks but what if I have 2000 frames I would like to join together, is there some formula or something ? May you write some example ?

It tells you how in the instructions in the link above


eg.

img_0002.png

img_2000.png


ImageSource("img_%04d.png" , start=0, end=2000, fps=29.97)

You might take a look here:

That script is adapted for special purpose, you need to modify some settings to default.

AUTOCROP_THRESH = 0.0
SCANPERC = 50.0

You can change other settings to taste.

You also need RT_Stats v1.06 which includes QueryBorderCrop.avs and QueryLumaMinMax.avs, and GScript.

It joins together pics of different sizes into a sort of slideshow, auto cropping borders, auto levelling, resizing or original size,
border padding to chosen aspect ratio.

If not in a hurry, wait a few days and I'll update RT_Stats together with an update to that script as a script function.

Sirt, see here for previously mentioned image splice func.

Sorry I haven't seen your last answers. Thank you. Then do you mean your latest script will allow to join frames whatever their origin ? I'm not sure to know how to use it, would you just give an example if I want to join frames 1.jpg, 2.jpg and 3.jpg for example ?

Give it the directory name, and how you want it to come out, fairly basic, try it out, it's pretty good and
perhaps better than any alternative, perhaps not, nobody is allowed to say "****", not on D9.

EDIT: You will not break it, give it a go, use your common sense, it dont need much instruction.

EDIT: If all else fails, just give it a directory/path (or as a last resort, put pics in same dir, and go to sleep)...
