<div dir="ltr"><div><div><div><div>As I stated in my book:<br><br></div>"While I will not claim to possess anything more than a passing familiarity with movie formats, I recognize that neither do many other people. For those who have had experience editing and creating movies and understand these concepts far more extensively, you can skip this section; be assured that I could not possibly add any new knowledge. For those reading on, there are likely to be some over-simplifications. As such, this section is only intended to provide enough information to successfully render animations and avoid pitfalls and should not be considered authoritative."<br><br></div>My quick research at the time found that while mpeg4 and h.264 weren't strictly equivalent, for all intents and purposes they could be considered as such. And it is my understanding that avconv and such were treating it as the same (unless explicitly told not to). If I am wrong in this regard, please refer to the previous paragraph and kindly file an errata for my book.<br><br></div>Cheers!<br></div>Ben Root<br><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Aug 15, 2016 at 1:23 PM, Chris Barker <span dir="ltr"><<a href="mailto:chris.barker@noaa.gov" target="_blank">chris.barker@noaa.gov</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div class="gmail_extra"><br><div class="gmail_quote"><span class="">On Mon, Aug 15, 2016 at 6:21 AM, Benjamin Root <span dir="ltr"><<a href="mailto:ben.v.root@gmail.com" target="_blank">ben.v.root@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div><div>In my research for the animation chapter of my book, I also came to the conclusion that the `mpeg4` codec in a .mp4 container was the best bet for out-of-the-box compatibility across platforms.</div></div></div></blockquote><div><br></div></span><div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Ben -- is that H.264?
