<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">What is your audio source format (container) and codec? If not already the case, try to use WAV audio (pcm_s16le).</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">You can also export video only at 60fps, audio only switching to 25fps, and then remux together with FFmpeg?</p>

<p style=" margin-top:12px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hey guys!<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Small update:<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Compiling the latest git of ffmpeg did not help unfortunately, also converting the audio to 48khz did not work.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">The only way I have been able to get rid of all audio pops in a 5 minute video is by changing the project profile from 59.9FPS to 25FPS or lower.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I am now convinced that it is actually the frame rate of the video that is at fault.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Now I use a lot of slide animations which I would like to be rendered at 60FPS in order for them to appear smooth.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Is there any way I can export the audio with 25FPS pacing, but still be applicable to a 60FPS source?<br /></p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I typically use up to 30-40 clips for one Youtube Video, which I upload daily.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">You can check out the channel if you'd like, it's "UFC Digest".<br /></p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Upsampling them to 48khz would be a pain, but I will try a couple upsampled test clips just to check if the pops go away.<br /></p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Right now I have compiled the latest version of ffmpeg git and I am rendering with different profiles and in different formats. <br /></p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I have read on the kdenlive forum that ffmpeg audio thumbnails could be related, seeing as many users have reported the same issue, but a solution was never found.<br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br /></p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Since Eugen specifically mentioned ffmpeg as the source of the problem, I will make sure to test every possible ffmpeg related scenario, before I move to the next workaround.<br /></p>

<p style=" margin-top:12px; margin-bottom:0px; margin-left:120px; margin-right:120px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">second the 48kHz suggestion. early on I noticed issues with 44.1kHz, switched to 48kHz and had no audio issues anymore, but then I stick with 25fps. use audacity to upsample.<br /></p>
