Need help position frames on the edit screen

Men, do I am missing something or is horrible to let the sprites on the correct position with multimedia? I mean on the edit screen of the animations, I can't let the standing frames on the correct position (like the left foot of the hero is always on the same spot in the standing animation.
On the mugen program "fighters factory" this is completly simple, you activate a "shadow" of the previous animation, hold the sprite with the mouse and put "the left foot on the top of the previous left foot".
I have to put the "hot spot" on the middle of the legs of the hero on all the frames, but this need to be "pixel right", so how I do that?

Click to set the hotspot. Hold down the Control key and click with the left mouse button. Now you have just set the hotspot for all animation frames at once. :)

No, its not that. how to explain... if I let the hot spot on the same coordenates on all frames the thing goes wrong, since the size of the sprites are diferent (the hero is breathing and so slight increazing and decreazing in proportions (left/right, up/down) while his foots are imobile on the floor)

So I need to let his foots on the exactly right position on all frames.
As I said before, on that mugen program I could left a shadow of other frame in the back and hold the sprite to position it. or I could move left and right arrow on the keyboard to compare the positons of the previous sprite to keep grabing and moving to adjujst the position.
But here I cant grab the sprite, just this "hot spot".

Edit: explaining in other way, lets say that I need to put the "hot spot" exactly on xx distance to the right of his left foot on all frames, how I do that?

You know your animations better than the forum members. Put the hot spots where it belongs using the animation editor.

that is the thing, the hotspot has to be in the middle of his legs, betwen his feets. but it has to be precize, so how I do it? if I just put in the place I consider correct, manualy sprite to sprite, when I put "play" it shows that there is mini errors (thats why I need to put the hot spot comparing with previous frames to adjust perfect.
so how I do that?

For best resulats animations should always be the same size frames, and just not always need to use up all the space. This way it would look correct no matter what the size.

Anyway, you may want to create an applciation with MMF2 to help you do what you described the other software in the first post did. It wouldn't be too hard ;)

Yeah, that is the thing, the size of the srites are diferent (and I tought that, if nbo other solution would appear I would have to fix that before puting in the mmf).

"Anyway, you may want to create an applciation with MMF2 to help you do what you described the other software in the first post did. It wouldn't be too hard "
humm... but it happens that I am new to mmf, so I have no idea how to do that.
But anyway, if there isn't a solution on mmf, I will try to discover some metod to make it work on the future, when I be inserting the true sprites of the char.
