Description Sam Muirhead 2016-01-01 16:36:59 UTC

When opening a saved project, if it contains any image sequences with a period in their filename, I get a Warning:Missing Clips dialog box and then I am unable to relink the files using Search Recursively.

The workaround is easy - either import the image sequence using the 'Import Slideshow Clip' option, or batch rename the files to remove the period before importing into Kdenlive as an image sequence. Both of these options work with no problems.

This bug is likely to affect anyone editing Synfig animations in Kdenlive because by default, Synfig exports PNG sequences with the pattern:
SceneName.0001.png
SceneName.0002.png
SceneName.0003.png
Of course you can change this in Synfig to remove the period and avoid the problem that way, but it would be a nasty surprise if you had done a lot of work on your Synfig animation in Kdenlive and weren't able to retrieve it!

Reproducible: Always

Steps to Reproduce:
1.Click on Import Clip, navigate to folder containing image sequence
SceneName.0001.png
SceneName.0002.png
SceneName.0003.png
...
2. Click on SceneName.0001.png, check 'import as image sequence' option. Import.
3. Edit the image sequence in kdenlive. 
4. Save SceneName.kdenlive & quit.
5. Open SceneName.kdenlive 


Actual Results:  
Warning: Missing Clips dialog appears, showing 'SceneName.%4d.png | File not found'
Use Search recursively to navigate to the right folder - no change, File not found.

Thanks for the report. Indeed, I found several major bugs in slideshows that I just fixed in git master and 15.12 branch. Please test again and let me know...

Tested - it works! great job, thanks a lot.

This bug has reappeared, at least in 16.07.70, I don't know if it existed earlier as well.
The problem occurs not only when there is a period in the name, but it occurs also when I rename the images to replace the period with an underscore.

To test the problem, you can download a project file and image sequence here: http://www.cameralibre.cc/owncloud/public.php?service=files&t=978f0b221ff5849decd66bf7d19c9773

To replicate the bug:
1. create new kdenlive project.
2. click on 'add clip'
3. navigate to 'electronics' folder and select breadboard.0001.png
4. choose 'import image sequence' option
5. click OK.
6. save & close Kdenlive
7. re-open the project, and you'll get a 'missing clips' dialog, and relinking the files with 'searh recursively' doesn't work.

Comment 5 Sam Muirhead 2016-04-24 08:13:43 UTC

ah - when you choose 'use placeholder for missing clips' then it seems to work as normal. So it functions ok, it's just that the warning dialog should not be appearing.
