comment Why doesn't my audio work in Quicktime (but does in other players) when combining an mp3 and video file using FFmpeg?
Do you have any MP4 files that contain MP3 audio that work in QuickTime?

comment How can I reduce the choppiness of my ffmpeg conversions
ffplay is a simple player from FFmpeg. It's generally used for testing, and I was too lazy to try anything else. It could just be me, or your player/computer, or both.

comment How can I reduce the choppiness of my ffmpeg conversions
Your two videos are using very different encoding settings. ET uses ABR rate control with -b:v 900k (I'm unsure if was two-pass), and your ffmpeg command uses CRF rate control with -crf 1 (why 1)? Also it appears that -refs is not being set correctly by your ffmpeg command. Does it decode better if you change -crf 1 to -crf 23 and add -refs 3?

I can't tell much of a difference: ffplay vid_test001.mp4 & ffplay vid_test002.mp4.

> "it turns out the original audio doesn't work either in quicktime." If the original audio file doesn't play in QuickTime, how should muxing with ffmpeg provide a playable output?

comment ffmpeg drawtext timecode filter using low frame rate
I'm guessing the following values are valid: 24, 24000/1001, 25, 30, 30000/1001, 60, 60000/1001.

You should provide your ffmpeg command and the complete console output. Otherwise we can only guess.

comment FFMPEG to stream to rtmp
Libav is a fork of FFmpeg that had their own so-called "ffmpeg". Then they eventually replaced it with avconv. The deprecated message provided by Libav (and the additional message from the Ubuntu maintainer) were worded poorly and confusing to users. ffmpeg from FFmpeg is actively developed.

Please include the complete ffmpeg console output that goes with your command. Which players and/or devices did you test? Does this issue occur with all inputs or particular ones? If possible please provide an input file if it is specific files that are required to duplicate this issue. Do you need -copyts?

comment What tools are available to make quality video introduction with visual effects programatically?
You didn't really specify and it could be argued that PNG counts as "video". Anyway, you could use qtrle (more info).

Yes, such as a PNG image with alpha (transparency) for a simple example.

You can probably use the FFmpeg overlay video filter to move various "layers".
