Honestly, I don't appreciate your condescending attitude. I did do some
research before coming here but found nothing that helped my
understanding. I also privately troubleshot for a long time. Only then
did I finally resort to asking for help. I have many external encoders
up and running fine. FFMPEG is the only one that's been giving me
trouble, probably because FFMPEG has been confusing to me for a long
time, and only recently have I begun to understand it a bit.
Now, that being said, when I use your command line suggestion it crashes
as before. The error (as reported by VirtualDub), if I understand the
log correctly, is saying that the input it's seeing is what I know
should be the output, and the output it's reporting is what I know
should be the final result after muxing video and audio together through
a separate VirtualDub process. Note, in all my functional external
encoder command lines, "%(tempvideofile)" specifies the output.
On my original line, there is no useful error message given by
VirtualDub. It just says that the "pipe has ended" after processing 0
seconds. But, using FFMPEG's "-report" function (which I found from
using Google, believe it or not, because your "true/false" statements
below made no sense to me), I get an error message of, "Invalid data
found when processing input." The source video, however, is not corrupt,
and works fine in FFMPEG on a raw command line outside of VirtualDub.
Thank you for your help thus far.

Have you tried google?
The following line works fine on a command line:
ffmpeg -i 01.mkv -c:v copy test.mkv
But that's not too closely related to this:
But if I try the closest I can in VirtualDub's external encoder...
Command arguments: -i - -c:v copy "%(tempvideofile)"
Here you're trying to let ffmpeg encode from stdin, which is different
from your attempt above.
But while googling, I noticed that %(tempvideofile) should be
VirtualDub's output file, which ffmpeg would use as input.
E.g. here:
https://encodingtalk.com/threads/virtualdub-save-direct-to-mp4-fraps-to-youtube-with-external-encoders.2446/page-2#post-13731
So you would use
Command arguments: -i "%(tempvideofile)" -c:v copy -f h264
"%(outputname)"
...it doesn't work at all. What can I do to fix this?
What, nothing? No console output, no feedback, no error message?
Apparently, you can use something like
"logStdout": true,
"logStderr": true,
Then ffmpeg would show you a lot of useful information in some log.
Moritz, knows absolutely nothing about VirtualDub (but how to use a
search engine)
