Why not write a blitz program that draws each frame into a huge created image and then SaveImage it to a bmp for png conversion? You could make the png loading very simple by naming each img1.png, img2.png, etc. Hopefully the files already have some numbering or else renaming all 1,200 would require another program in itself ;)
Read somewhere "LoadAnimImage" is limited to 1024 frames? Using B+.
If so, I guess you'd have to use two images. Maybe each could hold 600 frames.
For i = 1 to Num_Images tmp_Image = LoadImage("img" + Str(i) + ".png") ; Do a CopyRect from one ImageBuffer to the other here tmpX = tmpX + ImageWidth(tmp_Image) ; Move over for the next pic next
