Do I need fixbrokenchroma on a huffy converted

[insertdisk]

Do I need to use the fixbrokenchromaupsampling command in avisynth if I am using a file rendered to huffy? I use Vegas to capture and the fourcc shows as dvsd. I then open the file in Vegas and do my editing then render as an AVI using Huffy codec. I have the canopus codec installed and I don't know if it is being used intermediatly or not. I am just still learning. Will it hurt to use the fixbroken command or will it just fix it if it's broken?

On a seperate note if anyone knows how to use convolution3d in avisynth 2.5 on a dv file (huffy convert - YUV2), I would appreciate a sample script.

Fixbrokenchroma works only in YUY2 colorspace, you have to check if your huffyuv is in YUY2, for example if I export my DV in huffyuv from premiere i get RGB32 (I don't know why..)

I have my huffy configured to export as YUY2 - my reference to the fix broken chroma command is because canopus is supposed have a chroma problem.
There should be a way to get to configuration settings of your video codec and you can force huffy to save as YUY2. Also of note is that I send these files through canopus procoder as the last step of my process - avisynth > VFAPI > Procoder.
I would like to use Avisynth 2.52 so I can use the 411 reinterpolate filter that Fred Thompson refers to along with convolution3d but I can't figure out how to force my avi into YV12 colorspace.
Thanks for your reply.

I got Avisynth 2.5 to work the way I wanted by "ConvertToYV12"
