I haven’t tried your timelapse presents yet, but I’ll check them out when I get a chance! These days, I prefer to export images and create a super high-quality master video, which I transcode with Compressor.

It's then shoehorned into a new file container that contains most of the information, but not all. Things like hot pixel mapping seem to be missing. As the file isn't a real Raw, it means that Lightroom can't use the normal demosaic process to generate a nice clean new file. Essentially the file is half baked, not quite a Raw, but not fully a Jpeg.</p> <p>Personally I've lost a number of night timelapses to sRaw, and I'd recommend just using JPEG over sRAW for timelapse. Just make sure you have the optimum starting exposure and set the white balance yourself. Do I wish Lightroom could better handle these files? Yep, because then I might get those timelapses back. But I take a different route instead. Did you try my LR3Beta Presets for Lightroom timelapse?</p> Eric, You should familiarise yourself with the real difference between Raw and sRaw, which has nothing to do with Lightroom exclusively, but all Raw convertors. sRaw is a demosaiced format, meaning that the information from the sensor has already been processed by the Camera.

It would be foolish to show images on the web in any other color space. Also, this was only for illustrative purposes.</p> sRGB is for web display.
