JPEG crop/resize/add borders questions

[csaag]

Goal is to take a series of pictures from a digital camera and make a NTSC DVD slideshow to play on a fullframe TV.

According to an article here:
http://www.uwasa.fi/~f76998/video/conversion/

I should take my original pictures, crop them to a 4:3 ratio, resize them to 704x480, then add 8 pixels of black border to each side to make it 720x480.

So I'm trying to find a way to do all that.

Cropping is easy enough, although time consuming but I don't want to crop each picture at the same place so I think I'm stuck here cropping each photo seperately. I downloaded Irfanview which makes batch resampling to any size easy (Under advanced options, check resize & enter the desired size and also check the resample box)

So now I have a bunch of 704x480 JPG files. Now how do I make them 720x480 with 8 pixels of black borders on each size? Any way to do it with an automatic process rather than edit each picture individually? Can AviSynth be used to open a series of photos and resize/add borders and save the photos in JPG? I know it has addborder & several resize functions, but I'm quite a newbie with AviSynth and not sure how accomplish that even if thois can be done with Avisynth.

Yup, that's possible.

Just renumber the jpgs (when necessary) and load them with ImageSource (or ImageReader):

ImageSource(...)
AddBorders(0,8,0,8)
ImageWriter(start = 0, type = "jpeg")

http://www.avisynth.org/ImageWriter

btw, dvd can also be 704x480, so there's no need to change them.

I was able to load the following into VdubMod:

ImageSource("d:\TEMP\name%d.jpg")
AddBorders(0,8,0,8)
ImageWriter(start=0, type="jpg")

This loaded all of the jpg's into Vdub.
But what do you do to activate it?
I chose 'file->Save Image Sequence' but that menu only gives you
a choice of png/tga/bmp

When I used the scroll bar to go thru all the input jpg images, it 1st gave an error message that said 'Image Reader: Images must have identical widths' (these jpg's are all of different resolutions) then a message that said 'Image Reader Can not open DevIl library reading file xxxxx" for numbered pictures that extended past what I had for input (i.e I had 25 files, that message started with filename26.jpg). I just want to save the files to a different directory (or to the same directory with a different name - i.e no overwriting of the original file)

EDIT: I used Irfanview to resize all the pictures to the same size, that gets rid of the 'identical widths message'.

2nd question: As far as resizing goes, Can I use AviSynth if the pics aren't all the same res? If so, then there are several resizing functions - any recs on one to use? The camera gives me pictures that are sized around 2000 x 1500 pixels at maximum. Even with cropping I'd still be reducing them (to 704x480). I have no idea what function would give me the best output to reduce a jpg file.

thanks.
