Aspect HD Conversion Internal Bit Depth
Does anyone know what level of precision the the conversion code in Aspect HD uses? This would be when capturing/converting in Premiere or HD Link or just converting in HD link.
I know the final output is only 8 bit but I would be surprised if the code worked at this level. Also, how about the deinterlace and scaling algorithms - would I be better using After Effects for this or are they OK? When I deinterlace DV foootage I seem to get a lot of posterisation/banding compared to just straight conversion to interlaced. |

If you prefer AE they have nice algorithms, just not very convenient and slow. Most of the math performed in our filters and compression uses 16-bit precision integer SSE2 code per color primary.
