I have been looking in these forums for the exact problem but can't seem to find any matches. When rendering in Voukoder, it won't start due to an unknown error. If my specs are needed, it is an RX 7800 XT, AMD Ryzen 5700x and 32GB RAM
This can happen due to a video format error. Meaning your video settings in your NLE may be incompatible with the FFmpeg encoder you're trying to use. Classic example: trying to encode interlaced video using NVENC.
