Current best standard like H.264 or MPEG4 use still discrete consine transform, or integer transforms

Even latest H.265 code seems to use DCT

http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

http://en.wikipedia.org/wiki/High_Efficiency_Video_Coding

Yes, JPEG 2000 uses biorthogonal wavelet trasmform

If you are talking about scalable video coding them 3D DWT are being used

Daniel Robert Franklin

The Dirac video codec developed by the BBC allowed the use of the following wavelet filters:

Deslauriers-Dubuc (9,7)
LeGall (5,3)
Deslauriers-Dubuc (13,7)
Haar with no shift
Haar with single shift per level
Fidelity filter
Daubechies (9,7) integer approximation

However, it appears that more recent DCT-based codecs outperform Dirac. The DCT seems to be remarkably effective for video coding.

I've attached some links with information about Dirac if you are interested.

As per my views for video processing 3D wavelet is more suitable

Rudinei Goularte

Theoretically, any wavelet can be applied to video coding. The problem is properly to build filters and quantization methods. DCT is still preferred over wavelts (DWTs) since DWTs are computationaly much more expensive.
