Yes, it has hardware acceleration using vaapi or vdpau for rendering. The Manual (<a href="https://www.cinelerra-gg.org" target="_blank">https://www.cinelerra-gg.org</a> under Documentation) goes into detail but a test case from probably 2 years ago as quoted there shown below:</div><div style="font-size:small"><br></div><div style="font-size:small">Results of a particular test case performed on a Intel, 4-core computer, with Broadwell Graphics using an mp4 input video/audio file with dimensions of 1440x1080/29.97 fps is shown next (note, filename is tutorial.mp4). This may very well be a best case scenario! But clearly, at least on this computer with only 4 cores, the hardware acceleration seems to be quite advantageous. A comparison of the 2 output files<br>using ydiff as described in the Appendix (C.1) shows no obvious defects.</div><div style="font-size:small"> <span style="font-family:monospace"> <u>CPU usage</u> <u>Render Time</u> <u>File Size</u> <u>File</u></span></div><div style="font-size:small"><span style="font-family:monospace">none 388% 100 secs 36,862,542 h264.mp4</span></div><div style="font-size:small"><span style="font-family:monospace">vaapi 150% 19 secs 74,522,736 h264_vaapi.mp4</span><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 8, 2021 at 11:53 AM Zeke Williams via Cin <<a href="mailto:cin@lists.cinelerra-gg.org" target="_blank">cin@lists.cinelerra-gg.org</a>> wrote:<br></div><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">Is it true that cinelerra-gg is more powerful than kdenlive or openshot? The fact this program advertises as having hardware acceleration caught my attention. Something other libre video editors have no such feature.<br></div>
