Hello all and thank you Gunther for your continued work.
I'm sure this issue has happened to everyone on their first try at a holy grail, "day to night" time lapse so i hope you don't mind the question and subsequently, i hope i find a solution.
As you can gather by the title of this thread, I accomplished, what i thought was a good first attempt at a holy grail scenario but as the output video starts, the footage (clouds etc) are moving at certain speed and then when the stars come out, everything speeds up quickly.
Equipment used was Nikon D750, 14-24mm, Vello external intrevalometer (wired), qDslrDashboard (auto holy grail setting)
Editing: LRTimelapse, Lightroom
The resulting video starts off in the "daylight" portion at a certain speed then increases the more night falls and tapers off once night has completely fallen into darkness and stars are fully out.
I absolutely acknowledge what is happening here.
At first, the shots are at 1/60 of sec with 2 second intervals and then, by the time night falls and qDslrDashboard has ramped the exposure down to my maximum preset of 25 second exposure (still with 2 second intervals), the frequency between shots has slowed, resulting in an accelerating speed in video play back.
When i realised what had happened, i decided to painstakingly use key frames in Adobe Premiere to try to slow down the gradually faster night fall sections of the video. Brutal..
It was horrendous to try to get the speed to adjust so that the whole time lapse was the same speed. The result was less than perfect to say the least and i don't want to have to go through that every time in post.
Is there any solution to get the speed right "during" the initial capture of the time lapse? I've read of something called Interval ramping. I'm not sure the Vello can be programmed to ramp the intervals and it would be very hard to ramp the vello manually during the time lapse
I'd be interested to hear of how others have overcome this with similar equipment listed rather than purchasing yet another gadget to adjust the intervals on the fly.
Keep in mind that later at night, i want to capture as much of the night sky as possible so i want my exposure to be 25 seconds with a 2 second interval. (approx. 27 second total)
I thought about setting my intrevalometer to 25 second intervals at 1/60 during the daylight captures in the beginning but then that only eventually becomes 25 second exposures with a 25 second interval once night falls (equalling over 50 seconds)!
Thanks in advance and i can't wait to go out and try again with some new advice/techniques.
