Dan, I think that your builds have fixed or improved the syncing. Is this coincidence that I'm asking about these issues now?<br><br></div><div>It seems, the answers lie in<br>the newer release;<br>the matching of profiles, clips, export framerates;<br>

</div>Understandable, but for future reference you can also add the first<br>
project to the second project as a clip. However, this H.264 profile<br>
is a very poor choice for this because it is designed for distribution<br>
not for editing because the GOP size (keyframe interval)) is set to<br>
250 frames. At 23.98 fps, that makes the GOP over 10 seconds! That<br>
will make seeking and thereby a/v sync more challenging. You should<br>
use lossless for an intermediate file, and they are faster to encode<br>
as well.<br>
<div><br>

<br>
</div>Are you referring to just image quality or also A/V sync? Does the A/V<br>
sync look good in Kdenlive's monitors even after scrubbing or seeking?<br>

</div>There appears to be a cosmetic bug here. In a fresh project, the first<br>
time you open the Render dialog it defaults to the HDV group, and<br>
indeed HDV is not compatible with 720p23.98 (according to MLT and<br>
Kdenlive). This message should not apply to the H.264 render profile<br>
as it has no restrictions like that, but I saw the warning as well<br>
when I used your overlay project. So, there is some state bug that<br>
makes the render dialog erroneously issue that warning.<br>

<br>
</div>Based on this info, I do not need the original camera clip because it<br>
is the render output of the first project that is giving you a<br>
problem. I have not yet been able to reproduce this. I am not trying<br>
to use your complex first project because that would take some time to<br>
recreate with my own assets, and it does not appear to be necessary.<br>
<br>
So, I locate a 1280x720@23.98 clip in my library, add it a kdenlive<br>
project with same settings, place it on a track by itself, and render<br>
it with the H.264 profile. I check the output in a couple of players<br>
including Shotcut (MLT-based) and Quicktime Player on OS X, both of<br>
which are playing it with good sync.<br>
<br>
I open your overlay kdenlive project and replace the clip that is on a<br>
track with the output from the preceding step. I render that out using<br>
the render settings stored in the project file you provided (dual pass<br>
H.264). The A/V sync of that output is good as well checked using same<br>
players.<br>
<br>
Can you reproduce the problem by simply placing a clip on a timeline<br>
by itself, rendering that, make a new project, add the rendered clip<br>
to a timeline by itself, and render that?<br>
If so, can you reproduce it using one of the binary builds I provided<br>
to this thread yesterday?<br>
