Combine single wavefront .obj objects into a clip sequence

Given many .obj files that represent the 3D pose estimation for each frame of a clip, how to combine the .obj files to form an animation?

After performing 3D Pose Estimation on a single human's dance movements, I exported every frame as a .obj file. How can I combine these single .obj files back to a clip in .fbx format for example? All that I need to do is put them sequentially one after the other, just as you do to image frames to form a video, and then I want to save the resulting animation as an .fbx file.

Thinking this should be easy with blender, I wrote a script to import all the frames in the editor but once I have them inside the editor, I have no idea how to form a sequence of these frames.

I guess this should be very simple question for blender but I never used the software and it would spare time to just know what to do.
