What I meant was that they weren't hired to do totally original animation, they are redoing existing animation, which is much easier. But they still have to create animation, which means they should know how to animate, which is unfortunately not the case.
There are lots of problems with SFHD, so many that I need visual aids to describe them:

You can't blame those problems on the resolution increase or a lack of frames or the source material. Those problems exist because the artists didn't know enough about animation to avoid them. It's not an issue of resolution, otherwise Blue Ray Disks would look choppier than standard DVDs. You can't blame the source material, since it also has the same number of frames, yet it looks smoother. The problem is that the new frames have basic drawing errors that make them choppier.
Udon was supposed to just res-up the sprites. Sounds easy enough, but it still requires animation experience to make sure everything lines up correctly. But they didn't really follow the original sprites, they kept the basic motions, but they totally redrew the characters. Such a drastic change requires even more animation knowledge, which the artists were lacking.
It looks like they treated each frame as a single illustration, without checking whether it really fit in with all the other frames. It also looks like multiple artists worked on the Ken Sprite, and each one drew Ken in their own style, rather than following a model sheet. These problems are common errors, especially in the work of beginning animators, but they should never make it into a finished professional product.
At first I was impressed that Capcom USA decided to redo their own work for SFHD. The newest screens looked much better, with the less random coloring and better drawing. But seeing it in motion was a big letdown, because all the same animation errors persist in the revised work.
