I bet you dont know

hello a new one here, ok may be you know what I need, I have 2 quiestions:

1- I need to make an ´image sequence´ plane, let supose 10 imgs so the frame rate is 20fps during 1 seconds.. I need each img stay 2 frames, instead 1 wich is by default.. solving just that simple math I will solve the entire issue I have about that.

2-I have a folder, 10 imgs inside, diferent proportions and sizes resolution, I need these images to be shown in the plane that contains the sequence of these images, I need them to be shown at the correct proportions according to each image, not just the first img´s proportion selected to make this secuencer.

this 2 things are making me crazy since about 2 years 😭 I hope someone can help me on this 😄

Thanks for read 👍
