Subject: python script to render every nth frame


elenorcoli ( ) posted Tue, 29 March 2005 at 4:40 PM · edited Sat, 09 November 2024 at 11:43 AM

anyone got any ideas for this? i have markdc batchgen, but it uses a draw all method which i suspect from reading the python methods pdf must render each frame. i use long animations to set up dynamic hair and cloth, but only require ever 10 or 15 frames. any help would be appreciated.

Here's a really basic one that will do the job. It's set to step by 10; if you want 15 or something else, just change the line near the top from STEP=10 to STEP=15 or whatever. This will put the images in the same directory as Poser.exe. Important note: You need to have "Render to new window" turned off before starting this. Also, if you want to have previews instead of renders, change the line scene.Render() to scene.DrawAll()

FYI, Poser 6 has this option under Animation/Make Movie. Looked but did not see it in earlier versions.

Phil, just out of curiosity, does P6 finally allow Python to save New Render? I haven't received the box yet.....

you can tell poser6 to save your last render or you last 10 renders if you wish and they are cached and still there for export when you reopen the program

Just in case it's not clear, you need to rename the text file to something.PY before using.

What about a python script to take the frames of an animation and reverse them, i.e., in a 10 frame animation, 1 becomes 10, 2 becomes 9, 3 becomes 8, and so forth? Is this the kind of thing that could be done using python? Or is there a script already for such? This would be useful for taking - for instance - talking walk designer walk cycle anims and having the figure walk BACKWARDS. No intention to "deviate the thread", as so often happens around here. Thanks in advance. Larry F

you all are gonna hate this..... i keep getting a syntax error that points at the saveimage or the ( right after it. i've messed with this thing numerous times... are we sure this script works?

Attached Link: http://ockhamsbungalow.com/Music/FrameSkip.zip

Answering both: Not sure why the syntax error. Sometimes these attached texts have formatting problems, sometimes a word processor will mess up the formatting. Indentation is important in Python. (Actually there was a more obvious error in the script, which I also fixed; it wasn't changing frames!) I put the FrameSkip.py and a FrameReverse.py for Larry into this ZIP, which should avoid the formatting problems.

wow, that was really cool of you thanks!

It's kind of strange to use a ZIP for this purpose, because the ZIP is longer than the files.... but sometimes it's the only way to be sure the package arrives intact!

Say, ockham, that's tremendously swell of you! (Forgive the syntax - reading Evelyn Waugh lately, LOL)! I'm going to jump on that baby with both feet, which brings up another ---- er, never mind that! Thank you thank you! Larry F
