trying to lower sequence fps, no luck

Software Natron
1

Hello everybody, i am working in my hello world project, is a logo intro marvel style, i have my sequence 1-78, trying to lower the speed to 6fps, the viewer actually show me what i want, but when i render, its come out with the sequence using the 30fps project setting.
Anyway iam trying to export a movie of the sequence, because after using a merge, the 6fps dont take effect even in the viewer.
I dont know how to paste images here to show.

I hope can any of you understand my bad english :confused:

Why not setting the project to 6fps ?

i tried all the combinations, i left just 3 nodes in the project, the secuence, viewer and write, i tried all the combinations, and for example with 6 fps en project settings the time of the project is incremented, and with 6 in the other nodes, just the images shows very fast. Iam just going to make blank images (transparents) to match the fps i want lol.

Hi, you need modify the metadata, I don’t know how to do it in Natron, but there are many other free applications you can do this. For example in Nuke (isn’t free :slight_smile: ), addtimecode, modifymetadata, retime, find similar nodes.

maybe convert the 30fps video with ffmpeg. ffmpeg -i videoname -r 6 outputname
or from image sequence ffmpeg -y -framerate 6 -start_number 1 -i %03d.jpeg -c:v libx264 -q:v 2 -an -b:v 750k outputname with filenames like 002.jpeg, 078.jpeg

I have setup the ‘Read’ node to 6fps, then the ‘Write’ node to 6fps too.
It works.

Alternatively, you can use Retime node to lower the speed by desired framerate divided by original framerate, in your case 6/30 = 0.2 times.

thank you all, solved with retime.
