Yes, LTC timecode, CinGG scans various types of timecode (all LTC) and<br>
adopts what it finds in the edits.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">So far I saw this email on ffmpeg list</div><div dir="auto">---</div><div dir="auto"><br></div><div dir="auto">Idea: could a filter be developed in FFMPEG, based on example files we can provide, to identify the presence of an LTC-derived audio stream, and additionally identify which of the streams is the LTC stream.</div><div dir="auto">---</div><div dir="auto"><br></div><div dir="auto"><a href="http://ffmpeg.org/pipermail/ffmpeg-devel/2022-July/298993.html">http://ffmpeg.org/pipermail/ffmpeg-devel/2022-July/298993.html</a></div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
In pro filming environments, various cameras and audio recorders are<br>
capable of creating a synchronized timecode (jam-sync timecode),<br>
optionally also using external devices (Timecode Sync Generator). At<br>
this point in CinGG it is easy to do the alignment, just bring the<br>
edits to the timeline and use the "Align Timecodes" feature.<br>

As I mentioned, in pro environments this step must take place in the<br>
pre-editing (Resources Window) and not on the timeline and must also<br>
provide replacement of the low-quality embedded audio track with the<br>
high-quality external one.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">Well, but this mean audio scanning and trimming happen automatically? On timeline you can manually align audio and video ..or at least see if alignment worked as intended via waveform.
