Best AVCHD deinterlacing in Vegas
Hey guys,
I have use a lot of AVCHD 60i footage combined with some 30p footage from Flip Ultra Cameras. I am exporting to 30p for YouTube, so all of the footage from the 30p flip cameras looks fine, with no stuttering etc.
The problem is that whenever there is an AVCHD angle, it sort of “stutters” in motion or panning or whatever, sort of like how a 24p frame rate would, but remember i am using a shutter of 60p, recording to AVCHD 60i. When I pause the video and look at a single frame it looks like two frames are being blended together. Is there a way to change the deinterlacer in Sony Vegas for the AVCHD angle?? Thanks

Without being able to see it, I’m guessing that what you are seeing are the two fields of the 60i image blending because of the difference in motion. In your Project Properties (Alt+Enter), set your Deinterlace Method to Interpolate Fields and it should improve this.

Perfect! That looks much better, but I’m not sure why!
Isn’t interpolating a bad thing??

Define “bad”… it worked… that can’t be bad? 😉
Interpolation is the last thing to try because what it does is throw away half of the fields. Sometimes, there is so much motion between fields that there is no good way to blend them back together so you just have to throw them away and not use them. This means you loose half the vertical resolution but you also loose the blurry frames so it’s a trade off when all else fails.
There are other 3rd party solutions like Boris BCC7 which has a Deinterlacer that does more sophisticated motion sensing. There is also Mike Cash’s Smart Deinterlace which can do frame-and-field differencing. But if Interpolate is working for you… go for it.

I tried the smart deinterlace plugin, but I found that it didn’t work. Could that be because my project setting is set for SD when some of my footage is HD?

No, I don’t think that would affect it. If you apply it to a single event, that event should be processed at whatever resolution it contains. If you applied it to a track that may have caused some problems.
