John,
<div><br>
</div>
<div>If it is only happening on transitions etc. could you do an
export of your audio only at 25fps, bring it back into
Kdenlive as one continuous WAV file and mute all the edited
audio tracks and export again at 60fps? Or does that introduce
sync issues?</div>

<div>Hi, Eugen!<br>
</div>
<div><br>
</div>
<div>Yes, during problem there are no pops. They only appear
in the rendered output file. Another thing I have noticed
is, that they only happen at the beginning or end of
overlapping clips when there is a transition (Slide) or
Volume Keyframable Effect involved.<br>
</div>
<div><br>
</div>
<div>Yes sir, I use Lubuntu 18.04 and Kubuntu 18.04.<br>
</div>
<div>I just checked and the clips are ususally 44.1khz 16bit.<br>
</div>
<div><br>
</div>
<div>The only way I can get rid of all pops is if I render
with a 25FPS profile.<br>
</div>
<div>50FPS, 59.9 and 60FPS all produce the same pops.<br>

<div>Eugen, would you mind being a little more specific on
what you meant by 44.1khz audio and 60FPS video
interfering with each other over time, which causes
clicks? I have searched everywhere on google but could
not find anything.<br>
</div>
<div><br>
</div>
<div>Is there a solution for this problem apart from
converting every audio track to 48khz?<br>
</div>
<div>Switching the 60FPS profile to 25FPS and rendering
the audio produces no clicks, but the audio has multiple
blank parts and is unusable.<br>
</div>
<div><br>
</div>
<div>Hope you can give a little more insight in this
matter.<br>
</div>
<div><br>
</div>
<div>Thanks a bunch!<br>

<div>Hi John<br>
</div>
<div><br>
</div>
<div>It comes 2 things to my mind:<br>
</div>
<div>- Do you cut the audio at the zero point? In
Audition (for example) is a function that you can cut
only at that point (when the wave goes through zero)
to avoid clicks.<br>
</div>
<div>- When audio frequency (i.e. 44.1kHz) and video
frequency (i.e. 60fps) interfere each other after a
time and from there you get clicks. Video rendering is
always video frequency driven. This would be a FFMPEG
problem.<br>

<div>Hey Jean, thank you for that valuable info.<br>
</div>
<div>
<div><br>
</div>
</div>
<div>I have tested the 18.08 version that you linked
and unfortunately the pops at the beginning of audio
clips still occur, but I have made an interesting
discovery.<br>
</div>
<div>When I render the entire project, there are three
pops at the beginning of 3 clips, let's say at
01:23, 02:02 and 03:15 in the time line.<br>
</div>
<div>These audio pops only come up in the rendered
output, not during playback.<br>
</div>
<div>When I only render a small selected zone
surrounding the area where I know the pop will be,
it does not occur.<br>
</div>
<div>Only when I render the full project, they appear.<br>
</div>
<div>I have tried this with all three known audio pops
that I have spotted in the fully rendered project,
and each time they disappear when I only render a
selected area around them.<br>
</div>
<div>
<div><br>
</div>
</div>
<div>The next thing I have noticed is that switching
the playback settings betwen SDL and RTAudio can
affect this issue as well.<br>
</div>
<div>
<div><br>
</div>
</div>
<div>As you know me now, I will now enter full testing
mode and report back to you with a more detailed
analysis.<br>
</div>
<div>I will compile the latest melt, ffmpeg and co in
order to provide a full report, but I will use the
AppImage versio 18.8.0 which you have suggested.<br>
</div>
<div>
<div><br>
</div>
</div>
<div>Anything else I should consider?<br>

<div>I have uncovered a new problem with the
latest stable AppImage 18.04.1 release of
kdenlive which is very troublesome.<br>
</div>
<div><br>
</div>
<div>Randomly, kdenlive will cause a "click" or
"pop" sound at the beginning of an audio track.
I have observed that this happens the most when
two audio tracks are overlapping or a cut has
been made at the beginning of the a clip.<br>
</div>
<div><br>
</div>
<div>I have also found that audio pops disappear
in the same footage disappear when switching
from SDL to RTAudio in the settings.<br>
</div>
<div><br>
</div>
<div>I am using a fresh install of Kubuntu 18.04
with updates and <br>
</div>
<div>
<div>Mlt and ffmpeg versions all from the
Appimage, so this has to be a thing in
kdenlive or maybe the latest Alsa / Pulseaudio
package?<br>
</div>
</div>
<div><br>
</div>
<div>I have tried some stuff suggested in forums
such as exporting only the audio in wav, but
without luck.<br>
</div>
<div><br>
</div>
</blockquote>
<div><br>
</div>
<div>I have just uploaded the 18.08.0 AppImage
containing the latest MLT. Could you check if the
problem still happens ?<br>

<div>Hello Juku!<br>
</div>
<div><br>
</div>
<div>Thanks a lot for your contribution and
sorry for my late reply. Your help is very
welcome. I have now merged your contribution.
Regarding the tests, they need some work and
currently don't all pass and crash. We need to
work on that.<br>
</div>
<div><br>
</div>
<div>Regarding other tasks, we really need to
make a list of UI improvements that could be
done without too much knowledge of the whole
code. I will try to spend some time on it
tomorrow, help is welcome. But basically, if
there is any UI related thing that you want to
improve, feel free to ask and we can guide you
if needed.<br>

<div>My name is Juku. I am a film hobbyist
and I have been using Kdenlive for about 8
years. As I'm also a developer, I thought
I would try my hand on contributing to

<div>I have mostly been a web developer so
far, so I do not have much experience with
C++ (except for some tutorials) and I have
never done any Qt development.<br>

<div>I viewed the "Junior Jobs" section in
Kdenlive Development Information page and
tried to fix #384511 for start ("New

Christoph Feck in the comments below that
bug, I got it fixed and submitted the
