<p>Hi all. Hi Phill. Thanks for waiting. Look... At this time I'm making a lot of tutorials about new laws and decress, all related with covid-19, for help people in Argentina. I have not many time to test, but... Check this:</p>
<p>Today I did a special (to me) format video, 1080x2160, 120 seconds, 30 FPS. I always use png with transparency, alpha channel, and masks and blur plugin...</p>
<p>So, there are some unsuported formats by HW decoding (cuda or vdpau)</p>
<p><span>Decoder png does not support device type cuda. (using png not supported by HW rendering)<br />Decoder huffyuv does not support device type cuda.(using another not supported by HW rendering)</span></p>
<p><span>In this case, a mixed CPU-GPU sistem is used, GPU for supported formats, CPU for the rest, and need <span class="str">hwupload_cuda as a filter, somthing like "vf=hwupload_cuda" in video config preset box, but my CPU is too small to proccess all needed and allways is 100% (I'm working on it) and GPU just a little</span></span></p>
<p><span>Render::render_single: Session finished. <br />** rendered 3623 frames in 982.980 secs, 3.686 fps <br /></span></p>
<p><br /></p>
<p><span>Without tracks with png files: I add hwaccell in the video config preset box and this is the result (in this case a lot of CPU is used too)</span></p>
<p><span>Render::render_single: Session finished. <br />** rendered 3623 frames in 698.243 secs, 5.189 fps<br /> <br /></span></p>
<p><span>Conclusion: I need a new CPU. Sorry. HW encoding works and is possible to take adventage of that in CinGG</span></p>
<p><br /></p>
<p><span>Thanks for all. I'll do more test, but maybe the information is usefull to another people</span></p>
<p><br /></p>
<p><span>Sergio</span></p>

<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.</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;">Sergio,</div>
<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><strong>hwaccel_flags to (0x00000002) ?? </strong>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 /> </span></div>

<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>Oh! The more important topic ! Manual is amazing. I'm trying to translate to spanish (slowly) to read the whole book and colaborate with CinGG</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>
