I use camtasia studio, and after recorded the gxf i convert the avi to flash and with camtasia player(in flash increase a 50kb +o- ).
Matriax only captured a bit of the screen, and he worked super-slow, but I remember the videos being only like, 30 pixels of alteration in 5 minutes.
thanks for the comments

. Yes is true i using now promotion and i go more fast, but usually use MsPaint i think is a drug.
A question, Helm or anybody, yes is good view the great skill of the video, i like much the robot, process and the techniques. But is possible make a video showing the techniques/tools/hot-keys for learn to use correctly promotion ?
i think for me and for more people this will e more interesting

. For example i think now i have a good skill level and i can make great pixel-pieces but im slow, and think if every body show their "tricks" or how use promotion is a good start to understand after how Helm or anybody make the pixel-arts in this program(I beleive).
A thing i not understad is, my robotic dragon have a big resolution : 717x427 13mins = 2mb / and helm robot is 500x500 16mins = 6.9mb and helm use frame-skip i not ¿?.
