File talk:Mono Tube Damper.gif

File size

Dear Jahobr,

thank you very much for the animated illustrations of automobile dampers which seem to depict the actual function better than any of the other available images. I would suggest to use both File:Mono_Tube_Damper.gif and File:Twin_Tube_Damper.gif for the German and English articles on shock absorbers.

The only thing that worries me is the apparently very large file size of more than 17 MB. Does this reflect the actual server load when someone views the article with these gif-files embedded?

If so, would there be any way to reduce the file size?

thanks again, KaiKemmann (talk) 21:31, 7 April 2023 (UTC)

5,32 MB

Hi KaiKemmann. No, that usually not a problem. Wikimedia servers automatically render and store a version reduced to the size it's used in. Several optimizations are applied and the results are usually quit a bit smaller. (It was however a problem some years ago. Users made and uploaded hand rendered thumbnails. Some of them are still around and confuse people.) The 100px-example goes down to around 5,32 MB; still quite a bit; reducing form here is only possible with deleting fames or using the .webm version.

Interesting. When I move my cursor onto the thumbnail image to the right a descriptive box appears after a second or so which gives the file size as 36.4 kB, which sounds rather reasonable.

Where did the 5,32 MB come from?

Otherwise the .webm size is given on the description page as 400 × 1,904 pixels and 52 s x 564 kbps = 29328 kb = 29 Mb = 3,6 MB, if I am not mistaken.

Much better than the .gif with apparently only 203 × 945 pixels, 520 frames and 16 s duration which the system claims amounts to a file size of 17.74 MB.

If the 36.4 kB is the actual size I will go ahead and use the .gif images for the wikipedia articles without further worries.

Somehow I like the constant animation of the .gif-files better than having to click on the .webm to open an extra window which then needs to be closed again ..

Hi. You get the file size (5,32 MB) by right-clicking and downloading the file and checking. (Maybe some browsers can show it to you directly.) I can 100% ensure you that 36.4 kB is wrong. A 520-frame gif can't be compressed that small.

Webm is much better at compression; it is a modern format while gif is from 1987. You should stop worrying about this. This is not the problem/task of editors. File handling, compression and transmission is the task of wikimedia software developers. --Jahobr (talk) 23:04, 8 April 2023 (UTC)
