This has probably been already reported/discussed, but maybe not. It's just
a minor annoyance, but when rendering part of an animation, the frame count
is not very consistent.

For example, with command:

  povray test.pov +KFF35 +KC +SF25

the rendering starts with:

  Processing Frame 25 of 11

which is not what I'd expect (although it has some sense).

Is it a bug (worth (re)reporting)? Is it already solved? I'm using povray
3.6.1

I think it's always been like that. It makes perfect sense to me and I don't 
see a reason it should be changed.

2cents.

Perhaps the phrasing could be more clear, something like

    Processing frame 25 (1 of 11)
or
    Processing frame 25 of 35 (started on 25)
...

Take another example, say I have an animation of 200 frames and I render
only the last 150. Then I see:

  Processing frame 130 of 150

How many frames are left? Do I have to remember that there are 200 frames
and I started on number 51?
If this happens to you, aren't you be surprised when after "frame 150 of
150" the render doesn't stop and "frame 151 of 150" starts? If you say
"no", I guess this qualifies for a "you know you've been raytracing for too
long when..." item :-P

Anyway, it's just a minor issue, I just found the time to talk about it, but
it's not a big deal :-)

a) "Processing Frame 25 of 35" Doesn't tell you that it started on 25, but
okayish...

b) "Processing Frame 1 of 11" Doesn't tell you that there are 35 frames in
the entire sequence, but okayish...

c) "Processing Frame 1 of 35" Is just plain daft

d) "Processing Frame 25 of 11" Doesn't tell you how many more frames there
are to go, but okayish...

On balance, there are 3 info options that give some level of relevant info.

I favour seeing the total number of images that are going to be output (the
"11"), so that leaves only two options, b) and d)

However, I would also like to know what's going on at the start of the
render (in case I entered an incorrect set of parameters, such as +KFF11 and
forgot the SF). This makes a) and d) okay as a) now meets my first
preference if we are only concerned with the first message.

I slightly favour a) over the adopted solution of d), since I've by now
checked the output at the start, and, if I'm forgetful about how long there
is to go, gives me a countdown, but it's a minor preference.

ergo, the option adopted by povray is valid if not clear w/o RTFM (this is
not a insult - personally, I like debug info that doesn't require you to
RTFM, and would favour additional info during output, such as "Processing
Frame 25 of 35 (1 of 11)")
.

You know you've been raytracing for too long when your posed supposition 
includes multiple instances of 'if.'

I understand that it can be confusing. There are many such events with 
Pov-Ray. That's why I enjoy the program so much; I get so many chances to 
celebrate my own human nature through error propagation.

How about:

Frame number 12 (of 1..100) clock 0.04 (of 0.00 - 1.00)
This render job: frame 2-nd of 10..90 of 1..100


Second line of above syntax would be if substitute start/end frame are 
used.

Personally I would like something along the lines of

Frame 25 of subset 25-35.

My reasoning being,
It's similar to what is displayed for a full animation.
It tells the actual frame number.  This may be important if you're
rendering a subset to check that some event happens at the correct time.
It tells you how far through the processing is.

Maybe:

Frame 25, 1st of subset 25-35, of total 1-100 with clock 0.0-1.0

it's short and contains all informations.
