FFmpeg: Instructions for download and Install

[barlabumbia]

Hello everyone! I have a problem with generating video on Mac OS. I installed the latest version of ffmpeg and placed the downloaded file in the application folder and pointed to it in the video export window. Available video formats immediately appeared in this window, I select the desired one and start exporting, when the indicator reaches 100%, but the video is not created (a folder with .png and .txt files appears. Please help me solve this issue, I really need to make a video animation! Thank you very much!

It seems that the FFmpeg program is not launching correctly, probably because of security restrictions that you have to configure (since you downloaded it from Internet).

Can you open the Ruby Console, copy/paste the following command and type Enter.

Kernel.system ""#{Traductor::FFmpeg.instantiate.program_locate}" -h"

This invoke FFmpeg help. The return value should be true.

If you get false, I would have a look at the previous post about giving permissions to FFmpeg.

Thanks for trying) None of the above worked) But I am very grateful that you answered me so quickly, because it is so important to support each other) I will briefly share my story. I tried all possible methods that can only be found on the Internet, but nothing worked, although I managed to install ffmpeg without lipsodium and everything that is downloaded further. Chat GPT helped me, he wrote me the exact command for the terminal and I converted my first video! After that, somehow everything started working in ANIMATOR! Thanks to FREDO for his work and gifts! If anyone needs the command for the terminal, I will leave it here:

ffmpeg -framerate 30 -i ~/Desktop/test/image%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p ~/Desktop/output.mp4

Hi I had a similar issue - tried to generate a video, and it didn't work. See the log:

[fredo6]

Is there a double quote (after 1:4) in the name of the folder where Animator.

Also, if you post a trace, please use the txt file (_EventLog_video_generation.txt). This is easier to read than a screen capture.

ffmpeg -framerate 30 -i ~/Desktop/test/image%03d.png -c:v libx264 -r 30 -pix_fmt yuv420p ~/Desktop/output.mp4
where do I have to insert?

@Scit @fredo6 I see the same issue - all MP4 videos seem to be encoded as 25FPS regardless of what is set in the Animator clip creation UI. I am using a Mac Studio with macOS 26.6.2. I am not sure what version of ffmpeg I have; I think it was "inherited" from my previous Mac when I installed this Mac Studio and migrated the contents from my prior Mac.

Edited to add: I just updated ffmpeg to a build from a few days ago (downloaded from https://ffmpeg.martin-riedl.de/) and there is no difference. MP4 clips are still encoded as 25FPS even when, for example, 30FPS is selected in the Animator GUI.

This is causing some grief in my video editor (iMovie), complicating how I time some voice-over with the video content, and also with how I have the editor dissolve from one clip to another when frame-by-frame synchronization is important.
