Lightroom3 test:
Lightroom3 does appear to do a better job upsizing than perfectresize7
... However, lightroom3 does not except .bmp ...
so - yes save in tiff from TG2
Quote from: TheBadger on July 31, 2011, 12:50:02 AMBut even if you do this, you are only able to resize when exporting from Lightroom at the end of the process, this would be fine but for the fact that sharpening the resized image would have to be done blind, or in another program making the workflow even more cumbersome....
The resize should do the job independently of additional effects like sharpening.
Of course its nice to be able to process images to shift exposure, gamma or do other effects as well. Typically you might use a compositing package like Nuke for this - but its very expensive. If you are prepared to tune the effect by hand, Imagemagick makes a good command line tool.
Doing several passes on the image sequence is not neccesarilly a problem. I.e. from 100 rendered images, make 100 new images upsized, then run another process to create 100 gamma corrected images, etc...
Many people use Virtualdub or After Effects as cheaper alternatives to Nuke. (but only 8bit IIRC)
Virtualdub has many useful filters for sharpen and hue adjustments changes, etc
(
http://www.virtualdub.org and filters
http://neuron2.net/)
E.g. For Imagemagick - using the commandline after installing allows you to do this:
Convert format from bmp to png
convert image1.bmp image1.png
for a sequence of TG2 images:
convert "imagename.*.bmp" imagename.%04d.png
to also stretch the contrast:
convert "imagename.*.bmp" -contrast-stretch 0 imagename.%04d.png
to sharpen and contrast stretch:
convert "imagename.*.bmp" -sharpen 5 -contrast-stretch 0 imagename.%04d.png
etc...
other useful filters are:
-gamma and -levels allow you control over these aspects,
-adaptive-contrast, -brightness-contrast -sigmoidal-contrast
-color-matrix, -composite, -unsharp
-motion-blur, -enhance, -liquid-rescale,
see docs...

What is your profession if i may ask?
There are too many links ... Can you give some links for the " information theory " subject that you think are good neon22, preferably without much math?
Sorry - almost by definition - information theory is all about the math. Wikipedia is a good start.
as for me - I was in VFX for 25 years but now retired (Hmmm.. maybe not... sigh)

Video Enhancer:
Windows only, sorry cant test. looks nice though, particularly if you are an editor/compositor.
Pity - looked like a good contender actually even if its more oriented towards filmed footage instead of synthetic - which never wobbles around... (follow that link above about super resolution - its an interesting example of an approach using adjacent video frames to increase the SNR (signal to noise) ratio of the image. Just like the faked effect in all TV Crime shows where they can see the license plate after zooming in on a blurry pic.)
