My exports with timelapses and rendering animations just fail for some reason, I’m not sure why, I’ve never seen this error before and I’ve tried all different versions of ffmpeg I could find.
(I’m on krita 5.0, and I’m sorry if I formatted anything incorrectly, this is my first forum post ever lol)
What does your render animation screen say, does it show that it found ffmpeg? did you extract the archive and selected the ffmpeg.exe file?
You have ‘mixed slashes’ in the Video location file path.
Can you try again with all as ‘/’ ?
It wont let me change it on the first path and on the second one it doesnt make any difference
The FFMpeg path is correct, doesn’t have ‘mixed slashes’, and FFMpeg runs so it must be ok.
For the Video Location path, if I select a folder as the target folder and type in a filename, I get a forward slash before the filename.
however, I’ve tried it with both a ‘\’ and a ‘/’ and they both work for me except for sometimes a change from ‘/’ to ‘\’ causes a crash 
However, I can change the path slash character by simple editing of the contents of the ‘Video location’ value.
So, I’ve no idea why you can’t change it.
Can you stick with a Rendered animation for now with Export as Video:
If you put your FFMpeg folder on the Desktop and point to that ffmpeg.exe from the Render window and make the Video location on the desktop, do you see the intermediate .png frames being produced on the desktop? You should.
Then you should see them be deleted after FFMpeg makes an .mp4 video file there.
I can change the video location by just editing it, sorry if I worded myself incorrectly, when I’m exporting an animation I can see the png files being created but when I try to play the MP4 the photos app on Windows 10 says it cant play it, I even tried putting the video into a video editing software and it wouldn’t import,
plus I tried uploading the video to YouTube and
When I try to export a timelapse it dose nothing
So, it does produce an .mp4 file as a rendered animation.
In that case, the problem with a Recorder timelapse may be caused by confusion with the name or contents of the screenshot storage folder.
That’s another layer of possible confusion.
Also, I’m wondering if having the FFMpeg .exe on the D: drive is causing problems with drive:file access permissions.
Do you have any kind of anti-virus or any other third party security software installed?
For playing video files on Windows, the long standing advice is to use the VLC player because it’s free and it works and you can get it from here:
Official download of VLC media player, the best Open Source player - VideoLAN
Did you use the recommend options for .mp4 rendering? :
I tried moving ffmpeg to my desktop (the entire folder, not just ffmpeg.exe), and it gave the same problems, and then tried disabling my antivirus, still problems, my settings are exactly the same btw.
VLC also wont play either of the exported files that I randomly created to test
Two last shots:
Can you upload a screenshot of your Render Animation window with the Video option selected?
Just checking - did you get FFmpeg from here? :

If you did, which is reasonable, try this one instead:

Oh ****! It looks like the 5.0 release build is broken. This may cause all sorts of problems for people for some time to come, until the next release version is available.
This sort of thing is why I don’t update software unless I really have to.
