Dear all,
For years now, I am a satisfied user of Virtual Dub. I mainly use it to convert AVIs to animated GIFs and insert them in Powerpoint presentations.
Those animated GIFs always worked in Powerpoint 2003 and Powerpoint 2007, but not anymore in Powerpoint 2010. Some files work, others don't, and if I insert them as a picture in the Powerpoint slide, most of the time they appear as an empty frame with red cross.
Inserting them as a movie also does not help. In that case, the first frame is correctly shown, but in presentation mode, the slide turns completely white and the animation is not shown.
I guess that it is due to the conversion in Virtual Dub, because a friend converted the same AVI with a commercial converter (Camtasia Studio) into animated GIF and those run without problems in Powerpoint 2010.
Anybody has any ideas how to solve it ? It would be nice to have a working solution, because I have hundreds of those animated GIF's, and I cannot use them anymore in Powerpoint 2010.
Best regards,
Wim |

EDITED
Wim,
I was only able to reproduce the problem of 'turning to white' when playing a GIF.
You get indeed this problem when you insert the GIF as a video (via Insert > Video > Video from file...).
When inserting it via Insert > Picture, I do not see an immediate problem...
The presentation of a 'red cross' comes normally from the fact that the GIF-file is not found.
I suppose your GIF-files are/were present on the harddisk of your computer and that they are/were inserted in PowerPoint via "Insert" and not via "Link to File".
I did a test with "Hide extensions for known files" in Windows 7, but that does not seem to cause a problem.
I also did test by creating an animated GIF via VirtualDub and inserting it in a new PowerPoint 2010 presentation : no problem.
Do the problem GIF files play correctly when you open them via Internet Explorer ?
Can you put a copy of such a GIF file on the internet for testing purposes ? |

Dear Abrazo,
Thank you for the prompt reply.
I will add some more detailed steps below (all files I refer to, are for download on http://users.ugent.be/~wvpaepeg/ftp/Gaetan/).
1) I convert the AVI file to animated GIF with VirtualDub. You should see a material specimen that is loaded in fatigue and makes slight bending motions,
2) I have another animated GIF file that is converted by Camtasia Studio (stress.gif). This shows four quadrants which seem to "blow up" under deformation,
3) if you click on the file names in your web browser, they should both play properly. At least, they do in my Internet Explorer,
4) next, I open Powerpoint 2010 (Microsoft Office Professional Plus 2010, 32-bit, English version) and I insert the Camtasia animated GIF on the first slide (with Insert, Picture). This works, and when I switch to presentation mode, the animation plays fine,
5) I insert a second slide, and in exactly the same way, I insert the VirtualDub animated GIF on the second slide. I get an empty placeholder with the error "The image cannot currently be displayed".
The .pptx file is also on my download.
6) and now comes the best part. When I open the .pptx file in my Powerpoint 2003 (with a converter for pptx files), the VirtualDub animated GIF plays properly. That is why I had no problems in the past with Powerpoint 2003 and 2007.
The problem is that this issue is not very reproducible. I regularly give presentations on conferences. On some laptops on some conferences, all animated GIF's work. On other laptops some work and some don't.
I searched already on the Internet for a long time, but no answer to this problem. However, when you enter the search string "Powerpoint 2010 error "The image cannot currently be displayed"" in Google, you end up with some articles that suggest it is a problem of the video driver.
The Microsoft Knowledge base suggests that you should use "Paste, Special" to insert the picture, but of course, the animated GIF is not on the clipboard.
I hope this makes you a bit wiser.
Best regards,
Wim

Wim,
Good news...
I think I did find it...
When trying to open your problem-GIF from within Paint Shop Pro 9 (PSP - an old version already), I was not able to.
It gave me a message error : "Invalid LZW code encountered in file".
This gave me a clue, because I did not have this problem in PSP with your second GIF-file (stress.gif).
So, I tried by opening the problem-GIF in VirtualDub 1.10.4-test9 and exporting it again as an animated GIF.
This new GIF opened without a problem in Paint Shop Pro.
So, I supposed - meanwhile - in the more recent versions of VirtualDub, this problem must have been solved.
Now I did a Search on the VirtualDub forum and did find this:
> http://forums.virtualdub.org/index.php?act...ST&f=15&t=21300
Read the post from Phaeron at Nov 5 2012
So, if you should try with the most recent version of VirtualDub, it should go better...

> or direct download link: http://www.virtualdub.org/beta/VirtualDub-....10.4-test9.zip
N.B.: I searched for an indication on how Office 2010 opens GIF files (at my opinion it does not use the GIFIMP32.FLT file for it - dd. 4 feb. 2010)
And I must also say that on my personnel pc, I do not have a problem with your pptx.
At some forum I did find an answer of someone who thinks the problem has come from an MS Office update somewhere mid 2012:

Dear Abrazo,
Thank you very much. You solved the problem indeed !
It was my mistake not to check the latest release first. I was still using version 1.9.10, and because I had no problem with the animated GIF's in older Powerpoint versions, I suspected rather a compatibility problem with Powerpoint 2010, than a bug in the older VirtualDub program.
Thank you. You have saved me a lot of trouble. I just have to open all my animated GIF's once in the new VirtualDub release and save them again. Then they open properly in Powerpoint 2010.
P.S. I am also using Paintshop Pro v9, but I did not think of checking the file there.
Best regards,
Wim |
