Re: Low precision on time remap
site_archiver@lists.apple.com Delivered-To: pro-apps-dev@lists.apple.com ky I want to overlay clips from recording devices that are free-running (not jam-synched). Even though most of the clocks are pretty accurate, these are clips of live events that last a long time and over the course of many minutes it is not unusual for them to drift apart from one another by an amount that needs to be corrected. Time remap seems like a good mechanism to adjust things back into sync. But the speed value only seems to be able to retain numbers up to a precision of two decimal places. For example, enter 100.12345 in the user interface and 100.133 is what gets stored in the XML, which is not even rounded properly. The residual error over the length of an hour can be hundreds of milliseconds, which is not acceptable for many synchronization purposes. I can't figure out if this is an artifact of the user interface or some fundamental limitation. Is there a sneaky way to specify a remap speed with greater precision? _______________________________________________ Do not post admin requests to the list. They will be ignored.

I am not certain I have your scenario correct, so a few questions to verify. You have audio that is not in sync with video and are trying to adjust the speed the video to match the audio? Is you audio fine at the start, and then drifts linearly , or is completely ok and then at some point goes off? In addition, I gather from what you are saying that you are not really using xml is this workflow, but rather you are using that simply to display the values of the speed keyframes. Is that correct?
