When you click on the Format button, you also have to click on the subsequent "view" button that popups to see them and like the view option in the Preset menu, when you highlight one of them, a yellow tooltip shows up in the lower right hand corner with 1 line of information if available. I believe most can be used on the ffmpeg command line if you ran from a window. For example, one of these for mp4 is "moov_size" and that is effective. If you look at section 21.18.1 in <a href="http://ffmpeg.org/ffmpeg-all.html">http://ffmpeg.org/ffmpeg-all.html</a> these are the ones you will see for mp4. Or for mp3 of that url in section 5.3 as:</div><div class="gmail_default" style="font-size:small"><br></div><div class="gmail_default" style="font-size:small"> "For example to write an ID3v2.3 header instead of a default ID3v2.4 to

I put your five points in<br>
the manual, see if you like it. I append Plugin.tex and Tips.tex<br>
I don't think it's a good idea to waste time on Cuda either; after<br>
all, it's only for two secondary plugins. Out of curiosity, I noticed<br>
that among the pixel_formats that one can choose in the rendering<br>
window, in particular for h264/5-nvenc.mp4 codecs, besides the various<br>
420p, ... there is also a "cuda". What does that mean? How does it<br>
work? (it gave me a rendering error!)<br>
<br>
2- I don't know the new "Format" parameters of the rendering/Wrench<br>
window. Where can I learn more about them? Are they metadata?<br>
