The clip is export from Edius-X NLE using the Canopus (Grassvalley) HQX Codec which is capable of up to 8K, 10bit, 4:2:2 all-intra in AVI-Containers.

They arrive as YUV422P16 in AVS+ (due to info() and ffmpeg -i) loaded with FFmpegSource2(FILNAM, atrack=-1), further processing works fine. Results appear correctly in VDub2. The trouble starts with "Save as AVI" with constant "Video format negoation error". Output codec again is HQX, mode ist Fast Recompress.

Menu > Video > Decode Format... shows P216 as current format. Whatever I select as at least 10bit-output format: Error persists. Compression menu shows: "Valid pixel formats RGB RGBA YUY2" although the codec is listed under "Similar to Source: P216".

Strange enough: VDub2 has absolutely no problem to take any 10/16bit "hqxin.avi" and save it as "hqxout.avi" without AVS+ as Fast recompress with the same codec.

Any ideas ?
There must be some false detection/reporting.
VFW/DirectShow etc. version of Canopus HQX doesn't support anything above 8bit. It never did. Only Edius and Resolve can export/read 8bit+ data for HQX.
