Deinterlacing in Vegas Pro 13

[László Kovács]

Hi Steve,
With all respect, let me argue a bit.
If the output is required to be progressive, and we have an interlaced footage,
why would it be better not deinterlacing that media as a whole, just one single event?
Say we have 3 footages: A,B,C.
A is interlaced, B,C are progressive, project properties are carefully set to avoid any deinterlaceing.

Let’s edit a bit, and on the timeline we’ll have the events trimmed from the footages:
B1|C3|B2|C1|A1|B3|C2|B4|C4

Say, that looks fine, except A1 shows the “lines” so we have to apply a deinterlace plugin.
Then later we need to add additional edits, and it becomes
B1|C2|B2|C1|A1|B3|C2|C4|B5|A2

Can there be any reason why A2 should not be deinterlaced? (It is interlaced because it’s trimmed from “A” footage.)
So that’s why I think it’s better to deinterlace a media as a whole and it’s OK, how it works now.
In Vegas, if you set the desired deinterlace method in project properties, B and C stay untouched as they are already progressive. Deinterlacing will be done only on events trimmed from A and this is done automatically, the editor does not have to drag a plugin on A1 nor A2.

(It’s another question, that builtin deinterlacing was not the best, this is why I used to use Yadif.
But in Vegas14 there’s an adaptive deinterlacing too.)

Best regards
