Posted: Wed Mar 17, 2010 12:29 pm Post subject: Problems with gif animation |
|
|
I have made a Photoshop CS3 gif animation that is having problems with pixilation and ghosting, or just freezing, but only when it is loaded up to a certain website. The large image works ok, but the compressed image does not animate. See the dancer animation here (you may have to select the top image first):
https://www.xstreetsl.com/modules.php?name=Marketplace&file=images&ItemID=2186911&ImageID=3397461
The shark animation is testament to the fact that it can be done so it works on both sizes (that was done about two years ago on a previous version of PS, and I cannot recall the settings). The animation must work on both sizes as they are used independently on other web pages.
The “Optimize Animation” settings have been used, and both the “Bounding Box” and “Redundant Pixel Removal” options were selected. I have included another file on that page with the “save for web & devices” settings.
Any informed ideas greatly appreciated |

Without the original PSD it's hard to say where things went wrong. Is there a chance we could look at the original file? |

asakatali, I don't see any file. Be aware that the forum most likely has a size limitation for attachments. In that case you have to find another way to share the file. |

I see indeed ghosting from frame 63 to 66.
If the file that you posted here already has those settings applied, then it's difficult for me to find out what the real cause was, because I was hoping that you still had the original file with none of the settings applied.
Now it's sadly impossible to say of it was already a problem in the original (most likely) or accidentally added by Photoshop. |

The file I posted was untouched. The dancer was originally a video which I looped (that's the superimposition you're seeing at frames 63 to 66 - perhaps 'ghosting' was an unfortunate term to use). I then imported into PS with "Video frames to layers" import function. That's the file I posted, untouched.
The problem is that on the link I posted before, [url]
https://www.xstreetsl.com/modules.php?name=Marketplace&file=images&ItemID=2186911&ImageID=3397461
[/url] the main gif at the bottom functions fine, but the smaller gif on top does not. Either it freezes (which is the most common result), or there is a ghosting trail of movement resulting in just a few abstract pixilated marks (often overlaid over a frozen frame of the rest of the image. Screenshot here:
http://rapidshare.com/files/365333301/dancer_still.jpg.html
The point is that the .gif works fine, but only when it is displayed as a thumbnail on that site are there problems. As I said I know that it can work (see the shark) but I can't recall the settings I used originally two years ago. I thought it might have just been "Redundant Pixel Removal" in the "Optimize Animation" settings, but nope.
I can post the original avi file if you want, though I don't see the point. |

I opened your PSD file, resized it to 80x60 pixels and saved it as a GIF file and it works just fine as you can see (Photoshop CS4 Extended 64 bit):
So I don't know where things went wrong, but there shouldn't be any problem to turn your PSD into a smaller GIF file. I also want to add that I didn't use the optimize function but even when I tried, I got exactly the same size file and also that one played perfectly.
Btw, if you look at both your images that you uploaded to your web site, then you'll notice that the big one is 62Kb, while the small one is 251Kb. It's important that you limit the number of colors used in the GIF file or the file size gets too large. I only used 8 bit colors (go lower and you'll get aliasing issues) and the final size is 32Kb. |

yes, the file does work fine, as well as mine does, until you load it onto that site - yours is the one on the right
https://www.xstreetsl.com/modules.php?name=Marketplace&file=adminitem&ItemID=2186911
You can see that still the small one on the top does not move at all, while it should. It is the same file as the big one (when the small one is selected). I only upload one file and the site itslelf produces a thumbnail from that file.
It is, however, interesting to note that the big one is 62Kb, while the small thumbnail (of the same source file)is 251Kb as you say. That must be causing the problem. The site must be designed badly to make the thumbnail larger i guess. Either way, i overcame it before with the shark gif. Alas, if only i knew how or someone could be smart enough to figure this out, i'm not. |

When did you upload that shark GIF? Hours ago, weeks, months?

All you're trying to do is find a workaround. The fact however is that Photoshop creates a perfectly fine GIF that not only plays well on this site, but also my site and in my third party file viewer. If anyone needs to be smart it's the owner of that site and you should also not have to figure out workarounds for mistakes he makes, it should simply work, period.
You should contact the owner. |
