The latest appimages don't work for me either, with pretty much the same log as yours. I tried making an appimage from inside Arch and this one works for me. You can try it too: https://limewire.com/d/e5a2146c-ca9b-426b-ba41-38a6f39ef34c#NZflAFyF_29jN-lB... Since Arch is a rolling, it is still best to compile from git. If you decide to try compiling, you must first install dependencies and then pass the various commands on the terminal to complete the compilation. Instructions can be found here: https://cinelerra-gg.org/download/CinelerraGG_Manual/single_user_build.html But you can ask for all the info and advice you want. A copy-and-paste summary is as follows: Install the dependencies described in: https://cinelerra-gg.org/download/README.arch This step will be done only the first time; the following ones you will go straight to copy and paste. Open a terminal and copy and paste the following lines: git clone --depth 1 git://git.cinelerra-gg.org/goodguy/cinelerra.git cinelerra5 cd /home/paz/cinelerra5/cinelerra-5.1 ./autogen.sh ./configure --with-single-user --enable-libsvtav1 make 2>&1 | tee /tmp/cin5.log && make install Each time you copy a command line, press ENTER and wait for the process to finish. The last command commits the CPU to 100% for a few minutes (with my AMD Ryzen 5900, it takes about 5-8 min). At the end of the compilation you can launch CinGG, again from the terminal; with the command: ~/cinelerra5/cinelerra-5.1/bin/./cin
