timelapse. how they do this

[rpt]

Try using StarStax... software just for this.

That is interesting! Thank you.

I need to adjust the setting for enfuse, but this is what I have so far.  It blends the images, ramping up to whatever the max is ($FILESPAN) then ramps back down at the end.

Code: [Select]

#!/bin/bash

FILESPAN=30
NUMBEROFFILES=`ls img_*.jpg | wc -l`
LOOPCOUNT=$(($FILESPAN+$NUMBEROFFILES-1))
for i in $(eval echo {1..$LOOPCOUNT})
do

CUTSTART=$(($i-30))
if [ $CUTSTART -le 1 ]; then CUTSTART=1;fi
CUTEND=$i
if [ $CUTEND -ge $NUMBEROFFILES ]; then CUTEND=$NUMBEROFFILES;fi

enfuse --output=eimg_$i.jpg `ls img_*.jpg | cut -d'
' -f$CUTSTART-$CUTEND`

done

I'll post something more final, which will also resize and make the movie later tonight.

Cool! Thanks.

Here's my final script.  Takes you from a directory full of images, to a movie.  I've got it running on 139 images right now, but it will take at least another hour to process (it kills a quad core 2.4Ghz 8GB).  It's just an image set I still had laying around from 2009, and not the greatest, taken on my trusty old XSi.  I'll throw the video on Youtube when it's done and post a link.

For the resizing and video portion of the script, this may be useful: http://www.canonrumors.com/forum/index.php?topic=2838.msg59581

If you want help modifying the rest of the script just ask.

Code: [Select]

#!/bin/bash

FILESPAN=30
NUMBEROFFILES=`ls img_*.jpg | wc -l`
LOOPCOUNT=$(($FILESPAN+$NUMBEROFFILES-1))

for FILE in img_*.jpg ; do convert $FILE -background black -gravity south -extent 4272x2403 -resize 1920x1080 RE$FILE ; done

for i in $(eval echo {1..$LOOPCOUNT})
do

CUTSTART=$(($i-30))
if [ $CUTSTART -le 1 ]; then CUTSTART=1;fi
CUTEND=$i
if [ $CUTEND -ge $NUMBEROFFILES ]; then CUTEND=$NUMBEROFFILES;fi

enfuse --hard-mask --exposure-weight=0 --saturation-weight=0 --contrast-weight=1 --output=EFimg_`printf "%04d" $i`.jpg `ls REimg_*.jpg | cut -d'
' -f$CUTSTART-$CUTEND`

done

mencoder "mf://EFimg_*.jpg" -mf fps=10 -o TLapse.avi -ovc lavc -lavcopts vcodec=mjpeg

Still processing, but here ya go:

Quite boring though, if the weather were cooperative this time of year I'd have taken a new series.

Some tweaks (and fixed a mistake).  I have this running on the same series right now, but the increased resolution (4k) and number of files mean it'll probably run all night.

Code: [Select]

#!/bin/bash

FILESPAN=60
NUMBEROFFILES=`ls img_*.jpg | wc -l`
LOOPCOUNT=$(($FILESPAN+$NUMBEROFFILES-1))

for FILE in img_*.jpg ; do convert $FILE -background black -gravity south -extent 4272x2403 -resize 4096x2304 RE$FILE ; done

for i in $(eval echo {1..$LOOPCOUNT})
do

CUTSTART=$(($i-$FILESPAN))
if [ $CUTSTART -le 1 ]; then CUTSTART=1;fi
CUTEND=$i
if [ $CUTEND -ge $NUMBEROFFILES ]; then CUTEND=$NUMBEROFFILES;fi

enfuse --hard-mask --exposure-weight=0 --saturation-weight=0 --contrast-weight=1 --output=EFimg_`printf "%04d" $i`.jpg `ls REimg_*.jpg | cut -d'
' -f$CUTSTART-$CUTEND`

done

mencoder "mf://EFimg_*.jpg" -mf fps=30 -o TLapse.avi -ovc lavc -lavcopts vcodec=mjpeg

nicely done. thanks

A way for Windows users to maybe do it with, f'rinstance, Lightroom....

Say we're using 130 total images, each one a 1-5 minute exposure.

Stack images 1-5 and process.  Unstack those, stack 2-6 and process.  Unstack those, stack 3-7 and process.  Rinse and repeat to the end.

Run the processed frames through a video editor.

Would be nice to automate this tedious process, though.  There's probably some Windows compatible software out there that can be adapted.

.....this could do the trick

Final version.  Rolling set of 60, and in 4k resolution for more stary goodness...
