How to select MP4 format in Video Combine's format input item?

[shixinsama]

Video Combine format I can only choose GIF and Webm formats. There is no way to choose the H265 MP4 format output. Where can I add this option?

The options for video outputs are unavailable when ffmpeg can not be found. The recommended fix is to either

• Install imageio-ffmpeg (see #77) or
• Manually download ffmpeg and add it to the system path.

Yes, I have already installed ffmpeg. But I forgot to restart ComfYUI, so I can't find it. This is my fault. Thank you for your answer.
