non-HDTV aspect

[devdev]

Many hd progressive and machine vision cameras have "odd" non-HDTV aspect
ratios and number of pixels, such as 1024x1024, 1600x1200, 1024x768 and so
on.

Can they be normally be easily manipulated in editing to be usable for Blu-Ray without artifacts, and perhaps with pillarbox pillars
added left and right, etc.?

too general a question to get a good answer. depends on the camera's codec, bitrate and whether or not it's proprietary.

If you're asking about the video recordings themselves, whether they can be converted to 'widescreen' by either adding pillarbox bars or cropping from the top and bottom, the answer's 'yes'. It will mean, though, reencoding the videos. Also, as aedipuss says, they have to be in some sort of widely recognized format. Posting a MediaInfo pic here will help determine that. And depending on what you know, this conversion may or may not be easy.
