Following up on an earlier post "amix vs amerge / how to" but now testing on
ffmpeg version 7.0.1
The overall goal here is to learn how (if possible) to take source files with
10 - 20 audio channels and mixdown / assign those in various ways to -- 2
channel, 4 channels etc etc -- it depends on

I'm looking to take Avid MXF outputs with up to 20 audio tracks, and mix them
down to various combinations, e.g. Stereo Mix, Stereo music, mono dialogue
only, Mono DM&E splits, etc etc. all kinds of permutations and combinations.
So the basic pipeline: Export MXF from Avid with "Direct Out" (i.e
Consider
- Always retaining camera originals
- Extracting the metadata using ffmpeg and maybe exiftool and capturing
that either in matching-named sidecar files and/or in a media asset manager.

How to merge and map 1 video file with 4 audio files?
We've have 1 video file, 4 audio files, all same length.
The video file is DNxHD36
The audio tracks are all .wav
The goal is to merge all 5 files in sync
Based on https://ffmpeg.org/ffmpeg.html#Advanced-options I tried the following:
ffmpeg
We've have 1 video file, 4 audio files, all same length.
The video file is DNxHD36
The audio tracks are all .wav

Based on https://ffmpeg.org/ffmpeg.html#Advanced-options I tried the following:
ffmpeg \

Currently testing .ass subcaps in a VFX workflow.
The goal is to drop specfic text over specific shots and the in/out points have
to be frame accurate
We're working in a 23.976 project.
Currently having no trouble using FFmpeg to generate frame-accurate subclips of
individual shots from a full-s
We've got 1920x1080 source
We want to letterbox top and bottom to create 2.39 aspect ratio, maintaining
that within the original 1920x1080
Then over the composited letterboxed picture we want to burn in timecode and
subcaps
We're currently achieving the letterbox by means superimposing a photos
I've got 2 different .srt files and was hoping to use them both simultaneously
to create burns in two different locations into the same video.
Currently I've got a watermark plus one .srt working just fine. Was hoping to
add the additional .srt.
The following CLI works just fine (ie Time code

Based on a number of different forums, I've been testing the following code but
so far no luck burning hh:mm:ss:ff time code into an .mxf file:
ffmpeg -i SourcePath \

I've got a DVCam deck (DSR-11), trying to digitize old tapes to a MacBook Pro
16" M1.
I'm able to successfully capture using a FireWire to thunderbolt adaptor, and
then a thunderbolt to USB-C/Thunderbolt 4 adaptor.
Amazingly this setup works using iMovie. Picture, sound, and time code all

We've got a bunch of mp4s that need converting to Avid-native MXF that they
can be dropped into a ../Avid MediaFiles/MXF folder without being ingested.
(In other words, bypassing the need to importing/transcoding and avoiding using
AMA+transcoding)
The mp4 sources are 29.97, 23.976 and 25fps (

I ran a single test with it, and the TTML formatting looked good, but I still
have to run QC against a full show.
