I have a very simple project with one video, mp4 and 3 video layers of the same video,
All the effects have no keyframes
1. transform and rotoscoping
2. transform and edge cropping
3. transform

At first I could see the video in Project Monitor to edit all.
I was completed.. all looked good in the editor.
I render the video and it turns out black.
- MP4-H264/AAC - highest quality
I try NVENC H264 ABR
- same issue..

Open another project I had saved.. and now it has no Project Monitor view.. it's black

Reopen the file I initial file I this is talking about and now Project Monitor view is black

After trying different things including rebuilding the project completely.

I installed the latest beta still same issue.

I would share the project file but doesn't look like I can.


Windows 11
AMD Ryzen 9 3900x
32 GB RAM
nVidia Geforce RTX 3060

try removing completely Kdenlive... i have no issue with latest build ( https://binary-factory.kde.org/job/Kden ... 64-gcc.exe ) on Windows 11 with Ryzen 1800x and Nvidia card.

the uninstall script can be find here: viewtopic.php?f=269&t=172868

P.S. switch also to OPENGL backend (on Nvidia cards)

You gave me a framing hammer, I went to a sledge hammer. I reinstalled Windows, back to windows 10. Not sure if 11 was part of the problem.

All good for now.
