Description santymo1999 2020-09-30 00:51:51 UTC
There's not much to say... Basically, I edited a 20-minute-long video, and after processing it and turning it to .mp4, it kind of crashed. The video is a mess, audio doesn't go along with the video...apart from that, every black screen I added with text doesn't look as it should... In conclusion, the video looks perfect at the edition screen, but after processing and saving it, it messes up. I don't know what to do.

It could be that you use a couple of effects. Please disable parallel processing before you render. Then click on more options and pull the encoder speed slider to the far right with threads 0 to have a quick rendering.

Which effects in particular? About the other things, I'll surely try that.
Comment 3 emohr 2020-10-05 16:09:25 UTC
Different effects could be affected depends on the timeline (sometimes transform or zoom) as rendering with parallel processing could affect all effects

I didn't render with parallel processing. That's why I asked about the effects. Is there any solution that doesn't imply modifying all those effects?

If you work with 19.12.3 make a copy of your project file. Then Download 20.08.1 and try again. Version 20.08.1 solves a lot of issues due to comma/point decimal separator conflicts (project files saved with 20.08.0 and newer are not backwards compatible). Your render issue could be a part of this comma/point decimal separator conflicts.
Comment 6 santymo1999 2020-10-05 16:43:00 UTC
That's kind of funny. I did that, but the problem now is that kdenlive 20.08.1 wouldn't let me render the file. I issued a bug regarding that. I basically have two options: fixing the mess in 19.12.3, or understand why 20.08.1 crashes when I press the 'Render file' button (a sign that says something about a Qt file not being initialized)

Thanks for your help, you're being very useful. However, this program isn't helping. Whenever I solve an issue, another one comes out. Now, I'm facing two problems:
1) I restarted my computer. Now, when I open kdenlive and then try to open the project file, it loads until 70%, then the project appears in the timeline but it doesn't let me to visualize or edit it. Before, I couldn't render it to mp4. Now, I can't even see the video from inside the program.
2) I thought that maybe, despite not being able to see anything, I could try processing the video with the help you gave me. So I went to the link you sent and tried downloading that qt.conf file when I click on it, the only thing that appears in my screen is text saying "[Paths]
Plugins = ." Is that correct?
Comment 9 emohr 2020-10-05 18:45:57 UTC
Sorry for the problem you face. 
Yes the file "qt.conf" contains this information only. Put this file into the "bin" folder where Kdenlive.exe is. 

click: Help -> Reset configuration. If this is not working delete Kdenlive.rc as well. 

Please upload the project file here so I can have a look.
Comment 10 emohr 2020-10-05 18:50:59 UTC
Goto settings -> configure Kdenlive -> Environment -> make sure the paths of FFmpeg, FFpplay, FFprobe has the same root directory as MLT.

Comment 12 santymo1999 2020-10-05 19:02:07 UTC
Ok. There's the file you asked. Will you able to see anything, considering you don't have the files used?

By the way, problem 1 is fixed. The program was glitched and it showed me the 'Clip monitor' instead of the 'Project monitor'. 
About problem 2, I think I screwed it up. While trying to check the paths, after noticing that MLT had a different root directory, I deleted every path in order to copypaste and make them link. This didn't work, so I deleted everything and now the root directory is blank. Apart from that (I guess I can solve that reinstalling the app or checking manually for the path), I don't understand the steps to download the qt file you told me: can you give me specific steps to solve that problem? I'm not very good at this, sorry.
Comment 13 emohr 2020-10-07 12:46:07 UTC
Loading the project file the first time I get a crash. Load indicator goes to 71% and then jumps and shows the project in the timeline. Clicking into the timeline I get a crash.
Comment 14 Jean-Baptiste Mardelle 2020-10-09 08:23:50 UTC
@emohr: I can open the project file without crash on linux.
Comment 15 Julius Künzel 2021-03-16 19:08:02 UTC
Can you please test with the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and close this report if it is not relevant anymore?
