What rate should you capture the render target to get smooth video play back

Hey all.After trying various Screen Capture for recording my D3DX apps with no luck, was all way's getting flicker. I decided to save out the render target to a series of images. I'm using this as the time rate to capture the images. //calculate the milliseconds we want to capture a frame //there is 1000 milli seconds in a second float seconds = 1 / 24; Waittime = seconds * 1000; I'm also just using timeGetTime() //we only capture at the rate we set some where in render at the end before present DWORD time = timeGetTime(); if(CurrentTime - time < Waittime) return true;//not ready to take a capture Does this look ok or should I sample more less. and it was put together in windows movie maker. It was worth doing the other capture app took 500 milliseconds off my render(this one 110 ms) and stole mouse click it was such a scream. Here, what you think. I can post the code if anyone wants to see its not large all you need is the render target even multi sample had some trouble went to a 10.1 device and it still failed texture flags and things fixed it went back to device 10 I had heaps of helper functions in the code base that used the raw DX10Device pointer as it turns out you can assign a ID3D10Device * a ID3D10Device1 * and it works.

If you are capturing your own game, why dont you add some code to render it as if it could reach 60fps, but slower than realtime, grab the completed frames from inside your program and save them to disk yourself?
