How to fast import ProRes 422
I have a file that’s encoded with ProRes 422. I can’t get it to fast import into Avid. My settings are already YCbCr. I don’t know if it’s because of the dimensions. It’s actually 1280×544.

It is not a fast import because the source clip size is not the same as your project size of either 1280×720 or 1920 x 1080. The import is having to do a resize, pad, scale, etc.

Is there a way I can encode it correctly in MPEG Streamclip?
If I convert to 1280×720 to 1920×1080 in MPEG Streamclip, the dimensions of the video get crunched from the side. -
You might have to play with the crop and scale in order to get a letterboxed 16:9 clip at either 1280×720 or 1920×1080. Where are these files coming from with that X/Y pixel count?

AMA the file and then transcode. Import is a legacy method and doesn’t use all the cup cores. AMA then transcode can be much much faster and you can subclip before you transcode.

Just be aware that a fast import of a ProRes file is done by import, not AMA. But in the end, AMA may be faster than trying to figure out hw to preserve original aspect ratio within a 16:9 raster.

I did the AMA. How do I transcode now?

Well if you feel you have the performance to continue editing via AMA, give it a shot. If you want it to be Avid managed ProRes or DNxHD, the process is the same; highlight all the clips in the bin, go to clip and select consolidate/transcode. Once the new window opens, select transcode, target drive, and codec. Then OK.

Thanks for the tips. After I transcoded and exported, the dimensions are changed to 1920×1080. Is it possible to keep to the native dimensions?

No your original file was a non TV format size.
FCP can work st any raster size. MC can’t it’d limited to broadcast resolutions.
So if you have a non standard (Non TV) raster size then MCs not the best tool.Pat Horridge
