best way to capture opengl

best way to capture opengl

Im curious what other people use to capture opengl output.. Ive been using a second monitor output to a gl1 camera that records input to dv tape.. it would be so convinient to capture direct in computer.

I use Snapz Pro (OS X only). On PC I’ve heard Fraps recommended as well as Camtasia, which is tres cher.

I use iShowU. Works in conjunction with Soundflower to record system audio (plus you can record mic in):

I never got very good framerates with Snapz. I might have been trying
to record with big dims. What is everyone running at? Anyone doing
HD capture?

woh I just downloaded snapz and captured 740 at 24fps oh man it looks great and is so much quicker then my old method. Thank you so much for this! I am going to make so many more jitter videos now that I have a better and more conenient way to record! I always thought using screen grabbers would run slowly cause of the same comp captureing as its rendering but on my mac book pro it works like a dream, Ill have to play with it more but this is very promising!

I use the patch “jit.gl.render-tomatrix.pat”.
Often too loud for my PBG4 !

I haven’t actually tried it but Mr. Jones makes some pretty wicked shit.

I’m sorry for breaking in here but I’ve sort of been following this thread.
Very very new to Jitter myself. Does this imply that there is no native way
within Max / Jitter to capture output to a file ?

TIA

Nope. Check out examples/jitter-examples/render/jit.gl.render-to-matrix
as well as jit.qt.record. There’s your native way to do it. This
thread is discussing alternate means that may prove to be more efficient.

no.

it implies there is no efficient way of doing it ;)

I am on PC and I use Fraps, which I love dearly.

Hit one button: You’ve captured the openGL window as a screenshot in
bmp, jpg, png or tga – the current version of Fraps lets me grab
full-res, which on this system is 3360*1050, it auto-names the files and
puts them neatly in a folder of my choice. No user interaction needed.

Hit another button to start video capture. I’ve grabbed 3360*1050 video
@ 25fps as a test, and that worked well enough. For my little test
flicks it certainly does the trick too. It can apparently grab up to 100fps.

Snapz just went UB. They are both about the same speed now.

I used snapz a month ago on intel mac and there were issues about not saving audio and not recording quicktime output. I then switched to ishowu.

Btw just tried recording 3840 x 1024 with ishowu and I get no problems. (except from my desktop being suddenly overlaid by a 3 screens wide recording.. of my desktop. Took a few seconds before I figured that out :p)

@what fps, and how hard are you banging away at your video card
(seriously). That makes a huge difference. Anyway this is seriously
off topic :D

Fps, um no, good point. Doesn’t look like 25, more like 10 or so.

I expected the program to crash, but that must have been an intuition that I inherited from using snapz :D.

On MacPro 4 x 2,66 GHz. My graphics card is doing quite some work but I couldn’t say how much since I have no tool to measure that. Isn’t it about time apple included something like that in the activity monitor?

Off topic? Yeah you’re quite right :)

Have you tried using the OpenGL profiler in
/Developer/Applications/Graphics? I’ve actually been able to set
breakpoints on the GPU with it on my powerbook. alas, on my MBP, the
driver and OpenGL profiler don’t get along and the app seems to not
work.

You can monitor your GPU using the developer tools. There is Open GL
Driver Monitor and another tool whose name escapes me.
