Thanks, Grazie. Enjoying your good vibes! 🙂

The R’G’B luma range of this certain matte clip is 16-235 which is also known as “studio swing” or “limited range” and actually in this clip there is a “limited” color range flag.
Now some systems read this limited range flag and will spread the signal from 16-235 to 0-255 and some systems (like Vegas Pro) just ignore this limited range flag and pass the signal as it is.
So sometimes it’s worth to take a closer look onto Vegas’ waveform monitor or histogram to see the actual color range used in Vegas Pro, especially in cases of compositings where using precise R’G’B’ values for doing a correct math are crucial. -
The luma values of the MP4 matte file aren’t correct if them are meant to be white = opaque and black = transparent, it is not #FFFFFF and #000000. But you could correct the values by adding the Levels FX using the “Studio RGB to Computer RGB” preset.

Could you share your matte source file?

“I asked that she submit a request to the Canon development team that they program Canon Cinema RAW Development to output a DNxHR 444 for Windows”
Bear in mind Vegas Pro would need a MOV wrapper for this kind of video. It does not read MXF wrapped DNxHD/HR.

Mmh, while other types of DPX files work fine for me in Vegas Pro, these certain ones do not work. Don’t know why.
The only difference I see is the DPX files I usually work with don’t have any framerate information, but these Canon ones are said to be -0.000 fps (according to MediaInfo). Maybe there is something in the header which makes Vegas Pro to refuse them.

Can’t you offer a download of a few DPX frames instead? That would be only some MB and would have been quickly tested.
DPX sequence import into Vegas Pro usually works fine here so far.

Yes, this works fine for me in both Vegas Pro 14 and 15.
Any chance to share a small part of such a sequence of yours (3 frames/pics should be fine) for download?

Select a Loop Region and just drag down the envelop within that selected Loop Region.

In the “View” dropdown menu of Project Media deselect “Media Tags”.
