Had a trip to National Botanic Garden of Wales which has a butterfly house where I took some pictures. On arriving home i found I had what looked like a series of nine pictures that may I thought make a decent .gif.

wKGdnAZ.jpg


How would I do this in penguin land ?
With the "convert" tool I hear you cry. How did I use this tool ?

Placed all nine pictures in a new folder.

Opened a terminal in the folder or you could cd to the folder.

Used these two commands

Code:
$ convert -resize 1920x1200 -delay 100 -loop 0 *.jpg myimage.gif

$ convert -resize 640x400 -delay 50 -loop 0 *.jpg myimage.gif

Which gave these results, (click for real size)




I decided to use " -resize " as the originals were 4928x3264 which I could have used but it would have made a pretty big .gif.

Also there are a number of guides showing how to do this same thing out there on the net with " -delay 10 " which will give you a picture change every 0.1 second. That for me was a tad quick so I used " -delay 100 " to give me a one second change, " -delay 50 " for a half second change.
The " - loop 0 " makes the .gif loop continuously, pretty obvious. You can leave out the command to just run the sequence once. Or you can do " -loop 10 " which will repeat the sequence ten times, adjust the number to suit.

Running the above on my old 32 bit Dell I thought would take a long time but the command zipped through in less than a minute to give me the .gif. Pretty neat time for an old throwaway pc.

Help me out here folks,

Which of the .gif's look best from a picture speed changing viewpoint ? The half second or the one second speed.

Ta in advance folks

A nice and simple command line tool - I like it!

I prefer the slower speed, but smaller size image :).

I notice that you converted the images to a .GIF, which isn't ideal at handling high quality images (in terms of compression and colours). However, when you've uploaded it to imgur, it's converted to a .GIFV automatically - which is essentially a video file container.

You may get better results by converting the JPG images to a .MP4, and then let imgur convert it to GIFV - it'll mean you get the better image quality and a smaller file size :). I've got no idea how to do that in Linux though :lol:.

To make a .mp4 from .jpg you can do this,

Code:

The blue highlight is the code. This made a working video playable in mpv but for some reason, probably a missing codec, not in vlc.
Imgur makes .gif's from videos from url's not it seems from uploads from a home pc. An I can not see how to upload a .mp4 to here. I'll find my dropbox password tomorrow and give a link to the .mp4 I created.

:cool:

It seems that the sites buggy software has struck again.

I highlighted the code whilst composing the post and everything looked as it should. However on completing posting the entry the blue highlighting has disappeared. :(
I am not a fan of the way quotes and code are done with the new layout, the old way was much more poster friendly. :rolleyes:

The "code" tags take out all formatting - however, if you use the "quote" option instead, it should retain all formatting :thumb:. In this case, it's worked as the developers intended, even if it's not how it may be expected.

Could not find a way to show a IMGUR.gifv so there is a link above for some more flutterbyes from the welsh national gardens. This time with a one and a half second delay.
The pupae cabinets are cool as are the strange caterpillars.

This is the code

Code:
$ convert -resize 1920x1200 -delay 150 -loop 0 *.JPG butterfly3.gif

On this old Dell

Code:
$ inxi -C
CPU:       Single core Intel Pentium 4 (-HT-) cache: 1024 KB
           clock speeds: max: 2992 MHz 1: 2992 MHz 2: 2992 MHz

it took about three minutes to convert 25 photographs to a .gif. On a modern pc it would be much faster. The time taken is not half bad as I was surfing the net whilst the conversion was running.

Ok thanks for the explanation. A pox on developers who think it is cool to take a way that working and "improve" it. All that these so called improvements do is put use users in a constant looping learning cycle and nine times out of ten they do not really improve anything.

rant rant rant :rolleyes:

Neat to know but a tad long winded for me. All that signing in etc etc and waiting for the site to load etc etc. I'll check it out if I ever find the time. :cool:


Nah its not long winded, it does it for you. :)

Here is a dropbox link for the .mp4. To be honest it looks pretty much the same quality as the .gif's. :cool:
