Description Unknown 2017-02-01 20:21:17 UTC
When I try to add multiple .png files into my Project Bin as an image sequence, they still enter into the Bin as individual png files -- not as a single playable clip.

Bug discovered while using:
Kdenlive 17.03.70 via ppa://kdenlive/kdenlive-master
Linux Mint (Ubuntu) 18.1 64-bit.
Qt 5.5.1
KDE Frameworks 5.18.0
Comment 1 farid 2017-02-03 01:02:53 UTC
i just tried adding a sequence of images as a slideshow sequence and it worked out fine. Using same version as yours under archlinux though.
Comment 2 Unknown 2017-02-03 19:27:47 UTC
Strange, I tried even renaming all 60 .png files (eliminating the spaces and having a numeric suffix) and still they were imported as individual images. I can confirm this because the default duration for a single still image clip in my Kdenlive settings is 5-seconds, and the default duration for an image in a sequence is a single frame.

When I CTRL+A to select all .png's in the folder and click "OK", they all receive a separate row in the Project Bin, and have a default duration of 5 seconds.
Comment 3 Wegwerf 2017-02-18 15:13:04 UTC
Jesse, did you add them a clips, then select them in the dialog, or did you use add slideshow clip (or whatever it is called, I rarely use that menu item)?
Comment 4 farid 2017-03-02 02:45:25 UTC
Could you please provide some feedback?
Comment 5 Unknown 2017-03-02 06:23:36 UTC
@Wegwerf, Yes, I went to Add Clip, then selected all of the images in the dialog box, then checked the "import images as sequence", then clicked OK. They imported with the duration I'd put in settings for single still images, leading me to believe Kdenlive was recognizing them as single images during import.

@farid, sorry for the delay in my replies -- been super busy with some new virtual reality projects. Cool stuff, but I don't want to let it sway my devotion to Kdenlive and free video editing. :) I'll try to be more prompt in my replies.
Comment 6 Unknown 2017-05-01 18:50:29 UTC
UPDATE:

Adding an image sequence through the "Add Slideshow Clip" method (using the Filename pattern method) produces the result I'm looking for: a series of .png images are imported as a single clip, moving at 1 still image per frame.

Currently, trying to add the same .png files as above using the "Add Clip", then selecting all and enabling the "Import image sequence" checkbox and clicking "OK" imports all of the .png files as separate files, each with a duration of 5-seconds.

CONCLUSION:
Maybe it would be better to remove this check-box from the Add clip import window (and probably the transparency checkbox next to it, since it would only logically apply to image sequences, anyways) and simply educate users to use the Add Slideshow clip method?

If we go this route, I would suggest finding a better term for the Clip. Industry professionals will recognize "image sequence", typically, as importing a series of stills into a single clip.

Maybe even separate the two into two different options: "Add Slideshow" and "Add Image Sequence", then create a layout similar to the "Add Slideshow" widget, but hard-coded for importing still images in a sequence? Just brainstorming, here.
Comment 7 farid 2017-06-11 00:57:31 UTC
Now, when I add a clip and check the import image sequence it doesn't work any more. This happened after an update:

Kdenlive 17.07.70
KDE Frameworks 5.34.0
Qt 5.9.0 (built against 5.8.0)
MLT 6.5

I prefer to add the images from add clip and set the length of them to one 1 in the settings. playback is smoother than adding the images as a slideshow clip. have you noticed this?
Comment 9 Unknown 2017-11-26 21:16:13 UTC
Maybe one possible solution would be to remove the checkbox in the Add Clip window and change the menu action name of "Add Slideshow Clip" to "Add Image Sequence"? That would be more easily recognizable for semi-pro & professional editors, and it would produce the desired result.

Thoughts?
Comment 10 Unknown 2017-11-30 20:50:11 UTC
@farid, I can't say I've noticed any performance difference between using the "Add Clip" method and the "Add Slideshow Clip" method.

Can't see the difference either anymore. Smooth image sequence playback is something I really really really need. Hope this gets fixed someday. As for your report I still can't reproduce it.
Comment 12 Unknown 2017-12-01 18:38:08 UTC
I just tried to import a .png image sequence I rendered out from Blender using 17.08.3, and got the same problematic result.

Steps:
(1) Click on Add Clip
(2) Check the "Import image sequence" box
(3) Navigate to folder containing the .png's and select all
(4) Click "OK"

RESULT
All of the images are imported separately as still clips and not as a sequence. Here's a video example: https://youtu.be/qMHl6I8WDjQ.

You have something missing maybe? Here it works fine.
Comment 14 Unknown 2017-12-01 20:41:56 UTC
Glad you sent that screencast Farid, thank you. I noticed in yours that you have the "Transparent background for images" box checked. Mine is unchecked by default. When I check it, the image sequence imports as expected!

So, the bug is this, then:

BEHAVIOR
When The "Transparent background for images" is unchecked, and "Import image sequence" is checked, image sequences import as stand-alone still clips.

EXPECTED BEHAVIOR
Regardless of whether "Transparent background for images" is checked or unchecked, when user checked the "Import image sequence" checkbox, images import as sequence.

Farid, can you confirm by trying to import a series of images with "Transparent background fro images" unchecked?

It works even with it unchecked. I think the issue might be a kde dependency?
Comment 16 farid 2017-12-18 03:08:50 UTC
Jesse could you please test if this happens both with JPG and PNG image formats?
Comment 17 Christoph Feck 2018-01-02 15:42:03 UTC
If you can provide the information requested in comment #16, please add it.
Comment 18 Unknown 2018-01-02 21:27:18 UTC
I'll try to grab some .jpg image sequences and test that, but I can confirm this happens on .png sequences.
Comment 19 manuel_songokuh 2018-03-04 22:30:30 UTC
hi, Jesse, you can add your file png original and we will check for "reproduce" okay?

my case is not reproduce your report..


 but i can confirm little problem but not serious:
my file png has transparents and secuences.
in kdenlive i do "unckeck" to : "transparent background for images", kdenlive is imported the file png (transparent) result there are transparent.. i dont know 

why: phrase "transparent background for images" maybe is for JPG..?
phrase "transparent background for images" is not clear for information details..


i will wait from Jesse for file original PNG sequences.. thank you
Comment 20 Christoph Feck 2018-03-29 23:13:59 UTC
Jesse, to further investigate this issue, Kdenlive developers need the information requested in comment #16 and comment #19. If you can provide it, or need help with finding that information, please add a comment.
Comment 21 Christoph Feck 2018-04-26 21:36:32 UTC
No response, changing status. If you have new information, please add a comment.
