I've been a Vegas Pro user for many, many years. And always been happy with most of everything. The stuff I wasn't too impressed with has generally been fixed in later releases.
But Canon MXF format support is missing - and this is a catastrophic problem.
Yes, I know the clips will load just fine as Sony MXF files - but they're not Sony, and the results when rendering are a total disaster. No amount of twiddling Saturation, Color Balance, etc etc will get the clips to look even close to the way they did before they went into Vegas Pro.
It makes no difference what Project properties or properties for the clips I set. No Colour Space or format settings give anything close to decent results.
Every single project is a desperate struggle to find some kind of compromise that is acceptable and doesn't make me look too bad in front of my customers.
I get far better resutls with basic mp4 clips off YouTube than with Full HD Canon MXF, since 'Render as' results in the same general look as the original clip with just about anything other than Canon MXF.
Besides, Canon MXF is a huge player on trhe market and getting bigger. It CANNOT be ignored.
