https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #22 from Robert --- Hi, just curious if the bug I mentioned in my last comment is still on your radar: "If I render videos that have the ':' character in them, the output rendered video just shows blank white frames. I was able to work around this by renaming all videos in my project to not include the ':' character.". It's a bit different than the bug I reported, but I can file a separate bug for it if you want. If you need repo steps, let me know. For now I'll just keep re-naming all my files to ones that kdenlive can work with, but it would be cool if it worked out of the box. It makes doing backups easier without all the renaming. Also, is there anywhere I can do 'donations' to the kdenlive project (not kde overall) to help keep the bug fixers well fed? You guys should consider setting up a patreon. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #21 from Robert --- Hi, a brief update: - I've tried out the new kdenlive-19.04.1c-x86_64.appimage and the time drifting after saves issue appears to be fixed for me. - I've edited a fairly large project based on the same files, and I haven't gotten the 'Invalid clip' error again so that appears to be fixed. I have also been testing through opening with a desktop app shortcut which seemed to trigger the issue before. - I do still think there is still one bug which happens on rendering. I haven't dug into the source, but I have a hunch that there is another instance of the same colon related bug. If I render videos that have the ':' character in them, the output rendered video just shows blank white frames. I was able to work around this by renaming all videos in my project to not include the ':' character. Also, for whatever reason, I don't get this error if I run the kdenlive app image directly from the command-line. Not sure why, most of the environment variables are the same. If you need a set of repo steps for rendering bug, let me know. I anticipate that the previous repo steps should be easily adapted. -- You are receiving this mail because: You are watching all bug changes.

I can confirm the behavior described in your last comment. It only happend on project profiles with non integer fps, and the clip duration seems to vary slightly between saves.

https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #11 from alcinos --- Thank you very much with the in-depth exploration! When you don't accept to create the profile, or switch to an existing profile, it means that potentially the fps of the project and the fps of your video samples don't match. My theory, based on what you show, is that the fps conversion math (used for example to compute the length of the clips in frames), will create small but real rounding errors, and when you repeat that over and over the errors will compound. I'm a bit short on time right now but will definitely take a look soon, if confirmed it would be a serious bug. To be sure I reproduce exactly what you did, would you mind giving me the default fps of your projects in kdenlive? It should be displayed in the title of the app when you open a fresh kdenlive. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #10 from Robert --- Hi, Thanks for the response. For the ordering of the group encodings, I would like to cast a vote that the ordering be canonicalized somehow, or at least made predictable so that doing 'save as' with a project with no changes produces a new .kdenlive project with idential hash checksums (just for debugability). I'm fairly sure it's not a bad disk problem, I've experienced this in testing from my SSD and larger spinning disk.

Not sure if it's the one we're looking for. Long story short is that you should be looking for reproducibility in the ability to open a project, make *absolutely no changes*, then save the file. What I see happening is I can create a new project, add a single clip. Don't add it to timeline, add to project. Save project as. Re-open new project, change nothing, save as. Repeat this like 6 times, then diff the project files and you'll see a trend like this: a.kdenlive: b.kdenlive: c.kdenlive: d.kdenlive: e.kdenlive: f.kdenlive: g.kdenlive: Note that the time length keeps going down. If you add the clip to the timeline, you can see it move around and if you add multiple clips, empty spots slowly creep in. I did some tests to see if the change is deterministic, and doing 6 tries of save as from a single point seem to deterministicly change the track length. I also noticed that sometimes when I add a clip there is a message about creating a 'profile' for the clip. Sometimes it is a popup dalog you have answer, and sometimes it's a small sub-window in the clips area (why the difference?). I found that if you click cancel or ignore the message you get this time 'drifting' effect after save, but it never asks for a profile again. If I click 'create' the profile, it seems to stop drifting on multiple saves, so perhaps I really *have* to create a profile? If so, that message should be much more forceful rather than allowing subtle drifting and blank parts in the track. Another important point: Sometimes, I don't get that 'create profile' message at all. For example, if I add the Screencast 2019-05-21 14:55:40.mp4 video, then save exit. Re-open project, then add VID_20190520_093206251.mp4, I get *absolultely no* message about creating profiles. Whereas, if I add VID_20190520_093206251.mp4 first I get a mandatory prompt for it. Here are the source videos to test with: wget "http://www.robertelder.ca/Screencast 2019-05-21 14:55:40.mp4" wget "http://www.robertelder.ca/VID_20190520_093206251.mp4; No project file is necessary, create a new project from scratch. Now, that's one definite issue, but unfortunately, I was not able to reproduce the corruption issue all day today when launching kdenlive appimage from the command-line. I can often re-produce it when launching kdenlive by

https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #8 from Robert --- Hi, I just did a test to delete one of the solid colour clips with one of the clips that I have trouble with. I then saved it, closed kdenlive, then re-opened the file with no problems. Then, I made 0 modifications and 'saved as' the file again with another name. I then did a diff of the two 'idential' project files and found some of the xml tags moved around, but the content was the same. Then, I re-opened the latest project file and cut the offending clip into 3 major sections, deleted off a couple slices, and re-arranged the last clip so it was in the middle two on the end. Then I saved this file as '6.kdenlive'. Then, I found something interesting: If I open 6.kdenlive, then make no modifications, save as to 7.kdenlive, I can see what I think are functional differences in the 'children' section. See attached two files as an example (do a vim -d on them). Note that I can still load the project and it looks fine at this point as I can still edit/watch everything, but it seems fishy that these number are changing. I just did a re-open of 6.kdenlive and saved it as '7-again.kdenlive' which is idential to 7.kdenlive so at least it might be a deterministic change? Actually, after staring at the diff for a bit, I can see that the change affect the 'kdenlive:docproperties.groups' JSON array by re-arranging the order of the objects. I don't know enough about kdenlive internals to know if that is really a functional difference or not, but it certainly doesn't make reproducibility easier. -- You are receiving this mail because: You are watching all bug changes.

So, if this simple test with a color producer works, we need to look further.

See all artifacts at: wget http://www.robertelder.ca/colortest1.tar Also, you noted that my desktop QT version is old. As I understand the .appimage file gets around the outdated dependency problem by bundling all dependences. My question is, what important dependencies does it *not* bundle? I extracted it and I can see that it contains a copy of melt, but if this problem is specific to me, then it must be in a very low-level dependency. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=407778 --- Comment #3 from alcinos --- Ok, let's try to get to the bottom of this. First note: your Qt version (Qt: 5.9.5) is old, and it has known bug. This means that you have to stick to the AppImage. Now, using this appimage try this: 1. Create a new project 2. Go to Project -> add color clip, chose whatever color you want 3. It will add a color clip to the bin. Check whether you can visualize it 4. Add it on the timeline, resize it and move it a bit, and check if you can preview the timeline 5. Save, close the program, then open again the project and see if you can continue editing. -- You are receiving this mail because: You are watching all bug changes.

Hi alcinos, thanks for your response. I did (on at least one occasion), build melt from source and actually sudo make install it. I think I did that with v6.16? Same result when playing video/color:red. Having said, that, there are a lot of dependencies that the 'melt' executable relies on and I'm not 100% sure I uninstalled all its dependencies. Therefore, I did what I figured would be a stronger test which is build melt in a directory in /tmp/, and then do '. setenv' to let the mlt package do whatever it does to set paths, and then test the local melt executable that way without install. Same result. Here is the bug I filed for melt: https://github.com/mltframework/mlt/issues/445 Dan Dennedy suggested that perhaps there is an issue with my SDL2 (a dependency of mlt?). Even if that's the case, I would argue that kdenlive should be smart enough to detect this subtle corruption condition and at least issue warnings to the user for this situation where, clearly, an unmodified project file will have its track lengths changed without any modifications to the project. In such a case, regular warnings that say something like 'Warning: track length changed' might arouse suspicion and make it a bit faster to track down bugs. As of this time, I am not aware of any action item I can take to further assist in fixing this issue. The mlt bug I filed has been closed, and I don't know enough about SDL2 or how it interacts with mlt to know what to investigate there. Please suggest further courses of action. -- You are receiving this mail because: You are watching all bug changes.
