<p>Thanks a lot! Well...</p>
<p>pipe option isn't better in this case (I did some test). Changing <span> parameters to pass in the "view" button, ffmpeg option, not codec, is better. Attached images show some information to think it's using HW Acceleration. It's using 2 of 6 cores when before used all cores to reender. And use dedicate memory of graphic card and more GPU and video engine. Render time reduce about 25% and that's excelent </span></p>

<p>My original question was: Can I pass some imput parameters to ffmpeg in render process? And I ask this again. Why? Becase <span>ffmpeg </span><span>-hwaccel cuvid can enconder x264 at 13,7x and without this parameter, just 2.5x. And at the moment, x264 is sufficient for me.</span></p>

<div><span class="gmail_default" style="font-size: small;">One way to get parameters passed to ffmpeg while rendering is using the "Piping Video to a Command Line" (this was adapted from CV) and is documented in Rendering chapter 6 of the manual (6.5.6 section). I have not re-tested that in awhile but there is no reason that it should not be working.</span></div>
<div><span class="gmail_default" style="font-size: small;"> </span></div>
<div><span class="gmail_default" style="font-size: small;">The second way which might only work for certain parameters, is to click on the Video wrench in the Render Menu and try to see if the parameter you want to pass is available in either the "view" button which brings up another menu and on the top right hand side is the button "Kind" which defaults to "codec" but can be set to "ffmpeg". And/Or click on the "format" button which provides additional parameters -- these only sort of work and probably not what you want.<br /></span></div>
<div><span class="gmail_default" style="font-size: small;"> </span></div>
<div><span class="gmail_default" style="font-size: small;">A third way is just to write a Shell Command and use that via the "shell cmds" button in the upper right hand corner of the timeline by the "Ffmpeg use first/last button".<br /></span></div>
<div><span class="gmail_default" style="font-size: small;"> </span></div>
<div><span class="gmail_default" style="font-size: small;">None of these are easy and you are a brave man to attempt them !! Phyllis<br /></span></div>
