Storm Time-lapse from 2014 - 2015 footage - 26 March 2016
Throughout our storm chasing trips I have been collecting raw footage for time-lapses. On the whole this involves setting up the camera on a tripod, setting everything to manual, attaching a timer or using Magic Lantern's intervalometer, and leaving the camera to shoot for as long as possible. The storms always keep you on the move so it's not always easy to be in a place long enough to capture enough footage for a good sequence, but after 2 years of efforts I managed to collate enough to make something of it.
There has been a lot to learn, not least from the amount of efforts needed in post production for some parts, however on balance I feel it has given us a really good result.
Some of the key lessons have been:
- Ensure that everything is on manual, not just exposures but tiny focus changes can destroy a shot.
- Take shots slightly more regularly than you might first think - 3 seconds can seem enough but you can't readily add more frames, and storage is cheap, so take more footage and deal with the data later.
- Check the sensor between every sequence - ideally getting a picture up onto a high-resolution monitor. Removing a spot from sequences is much harder than simply applying a spot healer to the same spot on each frame. This looks fine for a single frame, but chained together gives very odd results.
- Ensure that your memory card is fast enough to take shots indefinitely at the speed you're taking them. Occasional waits on the buffer can make footage unusable.
- Use Photoshop for stitching the time-lapse. Lightroom's slideshow, with custom settings, does an OK job but is very slow and not well geared up for it. If you export full resolution JPGs from Lightroom, Photoshop is then very competent at stitching them, and great for final tweaks (not least removing the odd mosquito or ten that's made its way into the shot)
- Do it all in 4k if you can. I started this process targeting 1080p and half way through got a 4k monitor. When I realised just how good everything looks I went back to source to keep only 4k ready footage. It future proofs the footage somewhat, and just looks amazing.
I hope you enjoy the footage, please do share it, it's all out there for the world to enjoy.
