[bug]Slowdown: 336 pixel limit with avi recording
When recording at 336x200 (or lower) everything is fine. Going to 344x200 emulation is very slow. 336x400 or higher is no problem. Its just the x value.

Perhaps because it is not divisible by 16? Non-WinUAE issue most likely anyway (it does not care about size)

Most video codecs don't work well (or at all!) when the width is not divisible by 16 - this has to do with the use of vector (as in SIMD, not polygons) instructions from the MMX / SSE extension sets - so try restricting your x value to values divisible by 16.

Yep.. that's it.
Thought it was DIV8 not DIV16. GUI also snaps to DIV8 values. TSCC RGB lossless capture codec |
