This question is both confused and confusing. You'll have more success
if you use established subversion terminology correctly and avoid
making up your own terminology without defining it.

(I know it's a bit of a chicken-and-the-egg problem for a beginner.
See: http://svnbook.red-bean.com/en/1.5/index.html)

My guess: Subversion is working as designed and storing only the
compressed difference between the newest version of your 1.28 MB file
and some previous version of the same file. But, really, I can only
guess:

- Is the "1.28 MB file" a new to the repository, or did you commit
changes to an existing 1.28 MB file?

- What is this "transaction size" of which you speak? The size of a
file like $REPO/db/revs/12/12345?
- Why wouldn't you say "revision" in this case?
- Or are you really using a hook script to to peek at the actual
transaction during the commit before it becomes a revision?

- What is this "actual commit size" of which you speak?

- I assume you can successfully retrieve the "1.28 MB" file from the
repository. If so, the information must be there somewhere even if you
can't quite explain it to yourself.

- On that last point: http://svnbook.red-bean.com/en/1.5/index.html will help.
