[Kendrick-Stein]

Thanks for publishing your great work. I would highly appreciate it if you could help me with the following problem.

I was trying to run the example code and ran into this werid problem. The first two steps went perfectly fine, but the third command line 'python rerender.py --cfg config/van_gogh_man.json -nr' simply won't work. I figured out it was trying to read the image in path "videos/pexels-antoni-shkraba-8048492-540x960-25fps/out_1/0002.jpg" and similarly in 'videos/pexels-antoni-shkraba-8048492-540x960-25fps/out_31/0032.jpg'. but the file simply doesn't exist there.
I wonder what went wrong? Could it be in the first two steps?

The first key frame and the following key frames look fine to me? I guess it went wrong from rendering the following frames from the first one. E.g. rendering the second frame based the first key frame does not save any pic, and when it wanted to continual the rendering process, it found out that there are no generated frames from the previous steps?

[williamyang1991]

In your case, some images are generated but somes are not, rather than missing all images. So the Ebsynth is installed correctly but fails on some sub Processes.
I'm not sure the exact reason. But when the workload is heavy or GPU is nearly out of usage, we observed similar cases occasionally. Since we are not the developer of Ebsynth, we don't know how to fix Ebsynth.

• I think one solution is to use less multiprogress, like setting --n_proc 2 or --n_proc 1
• Another naive solution is to manually run Ebsynth on the interval where images are missing. For example, if you find 0002 missing, you can run:

python video_blend.py videos/pexels-antoni-shkraba-8048492-540x960-25fps --beg 1 --end 11 --itv 10 --key keys --output videos/pexels-antoni-shkraba-8048492-540x960-25fps/blend.mp4 --fps 25.0 --n_proc 1 -ps

likewise, if you find 0012 missing, you can run:

python video_blend.py videos/pexels-antoni-shkraba-8048492-540x960-25fps --beg 11 --end 21 --itv 10 --key keys --output videos/pexels-antoni-shkraba-8048492-540x960-25fps/blend.mp4 --fps 25.0 --n_proc 1 -ps

And finally merge all results together into a single video.

[Kendrick-Stein]

I was not able to run the Ebsynth on the interval using the command you suggest. It still encountered the same problem.

Based on the output, I guess it successfully read the pic 0001, but already failed to generate 0002? Is it a correct guess?

You can set OPEN_EBSYNTH_LOG = True to print more info

Rerender_A_Video/video_blend.py

I was able to solve the problem by reinstalling the ebsynth!
Thanks for your timely reply.

Hi, my ebsynth report that

./deps/ebsynth/bin/ebsynth: /usr/lib64/libstdc++.so.6: version CXXABI_1.3.8' not found (required by ./deps/ebsynth/bin/ebsynth) 
./deps/ebsynth/bin/ebsynth: /usr/lib64/libstdc++.so.6: version GLIBCXX_3.4.21' not found (required by ./deps/ebsynth/bin/ebsynth)

But I have CXXABI_1.3.7 and GLIBCXX_3.4.19 under /usr/lib64/libstdc++.so.6. Can someone hints me on how to set the parameters during installing? Thanks in advance!

Solved! I found that the gcc of installing environment is different from that in the running environment(in Docker). Reinstalling will solve the problem.

Hi how did you reinstall?

[343195246]

Please move the ebsynth.exe file and the ebsynth.dll file to . \\deps\\\ebsynth\\bin\\ path.
