Folks,
I had posted over at odforce but it seems to be down at present so I'll post here.
Basically what I'm after is to save my image sequence so that it's $F+600, so the first frame with be saved as MyImage.601.picnic etc
Arctor pointed me to the Expressions pdf section 1.8 where I had thought I had found the answer. It states to use a backtick in order to get Houdini to evualate the expression, i.e.
MyImage.`$F+12`.pic should work.
However when I attempt that, it doesn't evualate that but instead adds the ` to the filename and the + 12. i.e. the file is saved as MyImage.`1+12`.pic
I've tried forward ticks, double quotes, putting brackets after the initial tick and before the first tick but all to no avail.
So has anyone actually done this and can give me the correct format ?
Cheers
Starkhorn
ps I'm on houdini 6.1.208
pps Arctor thanks a mill for your post over at odforce.

Hi starkhorn,
It's working for me. Have you tried MyImage.`$F+12`.picnc instead? If this works for you, then something is not quite right.
Alternatively, you can save your sequence as it is, read it back with COPs with a File COP, append a Shift COP & type in the offset you want. Next thing is to write it out with a Composite ROP.
Please let us know how it goes.
Cheers!

No unfortunately trying with picnic or jpg or tga or any format type doesn't seems to work. I don't understand what I'm doing wrong…….
Forgot to add that I'm using WinXP and a US Qwerty keyboard so when I'm saying that I'm using a backtick `, I mean the button to the immediate left of the 1 button.
I guess I should be able to create the sequence ok by using a Video editor like Quicktime Pro or Media Studio Pro or something.
Thanks for the hint on COPS though….will check it out.
Cheers

Hi starkhorn,
Hmmm… it's working for me on Linux. I will try it out when I get home with Win2k & let you know how it goes. In the meantime, please check out COPs.
Cheers!

i just tried it out on xp.. seems to be fine.
another option i've mentioned to people in the past is a program called Renamer by Albert Bertilsson.. it's free and a great utility for mass renaming.. you'll be suprised how much it comes in use..

or you could even download Cygwin to have all those nice unix shell commands as well.

Hi starkhorn,
I just tested the above on Win2k & it works for me. I don't have WinXP so I can't test it for you. Can you put down a Font SOP & type `$F+12` into the Text field & see if it evaluates correctly?
Else, the COPs method is really easy.
Cheers!
steven
Hi Steven,
Well it evaluated correctly with the FONT SOP and when I put in the output field of the mantra render, test`$F+12`.jpg, it also worked fine.
However it still doesn't work for me when I have ip in the Output Picture field, then in the mplay window, when I got to save the current sequence with the same expression, it doesn't evaluate for me.
So my question is, when it worked for you, was it in the mplay window or in the output picture field ?
Thanks in advance.
Cheers
Starkhorn

Hey Starkhorn,
I tested everything in the Output field of a mantra ROP. However, if you want to shift the sequence in mplay to the frame range you want, type “Alt+L” to open the “Sequence List” dialog or look for it in the menu bar.
In the dialog, notice the button with blue colour in it which is under the “Start” label? Click on the button & the “Start” parameter will be active. Type in the frame number you want your sequence to start then this is the most important: you must click on the third button from the left (if you put your mouse over it for a while, the pop up will say “Fit Frame Range To This Sequence”).
Go back to mplay & click on the “Reset to First Frame” button ( |<< ). Notice your frame range has changed? Now saving out your sequence will have this new range.
Please let me know how it goes for you & if screenshots are needed.
Cheers!
