Hi, there is no redundancy in a movie. In movie compression technologies, the high compression rates are obtained with loosing quite a lot of information. So the I-Frame do not remove redundant data. They are on the contrary an acceptable trade-of on the picture quality. You can double check that by asking question: can you rebuild original movie from a compressed one (MPEG4 for example) ? The answer is no, because some data are lost. :-) Gtabary 09:36, 9 Dec 2004 (UTC) Sorry, this is completly wrong. There is very much redundancy in a movie, look at the fact that normally there are only minor changes between two frames. If you do it right, then you are not loosing any information by pixel prediction, wheter by intra-picture prediction nor by inter-picture prediction. You are loosing information by the quantization process and probably by the transformation (rounding errors). — Preceding unsigned comment added by Hahne9 (talk • contribs) 11:41, 16 January 2013 (UTC)Reply

Hi, I've tried to improve this article and mainly have changed the description. Please note that wiki links are still missing, I will try to add them later. It might be useful to improve the structure so that, for instance, the introduction to the article gets very brief and the extended description gets its own section.--New.limit (talk) 12:40, 6 December 2008 (UTC)Reply

This article appears to only consider algorithms based strongly on macro blocks. For example wavelet based algorithms are quite different. This should be mentioned, or the article generalized. Skarkkai (talk) 04:53, 7 June 2010 (UTC)Reply

You are correct that wavelet based algorithms are different, but they still use macroblocks, even though they are overlapping instead of sharply separated as in DCT macroblocks. The underlying principles of both remain the same with respect to the contents of this article. C xong (talk) 03:38, 29 July 2010 (UTC)Reply

A more accurate article title might be 'Interframe Coding'. The term 'inter frame' pulls up no matching references in searches (besides this article), so the audience for this entry would likely increase by creating a more accurate title to better reflect the article content. The article is about video coding / compression, and not just the 'inter frames' as you call them. Eric444444 (talk) 14:38, 8 December 2016 (UTC)Reply
