<p>Phyllis, Yes! just this parameter, but if you want, give me a few
day to more test. At this moment.. rendering 4minutes x 30 fps,
full-hd, with masks, 11.685fps, rendering same time with constant
zoom and chromakey, 9.04 fps. The detail is,before was rendering a
6 fps.<br>
</p>
<p>I want to test little more to confirm stability, HW rendering I
can confirm now.</p>

<div class="gmail_default" style="font-size:small">Thank you so
much for sharing your results which are quite impressive. Am
I understanding correctly that the only change you ended up
making was the"<span><b>hwaccel_flags to (0x00000002) ?? </b>allow_high_depth"
to the h264-nvenc.mp4 ffmpeg option file? I want to add
that as a choice for others to see. Probably your
newer/higher end graphics board was very beneficial -- a
good way to justify upgrading if using h264/h265.<br>

<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

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>
