How to process bracketed timelapse sequence to make a HDR timelapse sequence

Question

Hi everyone,I am an amateur timelapse and landscape photographer. I use LRTimelapse and Lightroom to process single shot time-lapse sequences (raw images). I was interested if there any plugins or technique to process multi-shot (bracketed) time-lapse sequences to generate a single shot (HDR) time-lapse sequence.For example, I have a time-lapse sequence 400 images with each image having 3 (+2EV, 0, -2EV) exposures, so I like to make these 400x3 images to 400 HDR (3 different exposures merged to make single shot with HDR image) shot sequence which could be later processed with LRTimelapse to produce HDR time-lapses with exposure ramping.

Batch processing of HDR merges is one of the most requested features: Lightroom: Ability to batch process Photo Merge (HDR and panorama) | Photoshop Family Customer Community .

You can start multiple merges more quickly by selecting three photos and doing "headless" merge -- Shift + Ctrl + H.

You might be able to auto-stack the 400 photos by selecting all of them and do Photo > Stacking > Auto-Stack By Capture Time. If that works, then collapse all the stacks (Photo > Stacking > Collapse All Stacks) and then select each in turn and do Shift + Ctrl + H. LR will queue up all the merges and process them one at a time. But you'll have to type Shift + Ctrl + H 400 times.

Unfortunately, you can't do the obvious thing, selecting all the stacks and then doing Shift + Ctrl +H, which would put all your stacks into the queue with one command: Lightroom: "Internal error" when initiating multiple headless merges | Photoshop Family Customer Community .

In four years, Adobe doesn't seem to care about this feature.
