[edit] Merging with video compression section

A merge tag has just been added to this article suggesting it be merged with video_compression#Intraframe_vs_interframe_compression, I'm just noting that I feel that the topics of this page are distinct enough that the warrant being separate. AlyM 21:04, 22 August 2006 (UTC)

If they are distinctly different things, then yes, they need different articles. But I fail to see the difference between "intraframe and interframe compression" and "I pictures, P pictures, and B pictures".

The merge tag is ambiguous. It could suggest either

Which option would you prefer? --70.189.73.224 14:39, 2 September 2006 (UTC)

I also simply oppose the merge suggestion (agreeing with AlyM above). They are different topics. It is possible, for example, to do interframe compression without using I, P or B pictures. Many wavelet-based or 3-D transform video compression designs do that. Maybe one article or another (or both) could use some improvement, and perhaps the video compression article should contain some reference to this article and vice versa, but merging those articles doesn't sound like the right way to accomplish the improvement. -Mulligatawny 22:21, 5 October 2006 (UTC)

[edit] Possibly incorrect article title

The title and first paragraph appear to be at odds with the rest of this article. The article gives information about all three frame types, yet the title only relates to B-Frames. Also, confusingly, I-frame and P-frame redirect here. I propose the article be renamed to Video compression picture types, Video picture types or Video frame types --Ozhiker 15:45, 29 November 2006 (UTC)

I agree. This article is about more than B pictures. I had been thinking of changing the name to "I pictures, P pictures, and B pictures." A new first paragraph might be:

"The three major picture types found in typical video compression designs are I(ntra) pictures, P(redicted) pictures and B(i-predictive) pictures (or B(i-directional) pictures). They are also commonly referred to as I frames, P frames, and B frames. In older material, the term "bi-directional" rather than "bi-predictive" is dominant."
