My input file is yuvj420p(pc, bt709). My target output is
yuv420p(tv, bt709). I would like to use "-pix_fmt +yuv420p"
to specify the output format, and to force me to be explicit
in my conversions in the filtergraph. How do I achieve
explicit conversions? The format filter appears to trigger

Is there a way to know how much processor time is going to encoding and
each of the filters? It would help me in making my commands more efficient
if I knew which parts were slow.

Hello everyone-
I am new to ffmpeg and am having difficulty locating documentation. I would
like to use Ut Video as a video encoding for intermediate files. How do I
know if this encoding is supported, and what options are available?

I have a video from a GoPro Hero8. It was recorded at 29.97 fps. I would
like to speed up this video. I figure it would be nice to simply increase
the frame rate to 60 fps, so a x2.002 speed-up.
Can this be done without re-encoding the video? I tried:
ffmpeg -r 60 -i in.mp4 -c:v copy -c:a copy out

In short order I got ffmpeg to read a video, apply a few filters (crop,
color adjustments, sharpness, volume), and output a new file. The extensive
documentation is a blessing to this new user.
After applying the filters, I would like to edit the video to shorten it.
Specifically, I would like to

This creates one image for each second of video:
ffmpeg -i 00020.MTS -vf fps=fps=1 -f image2 stills-%03d.png
When I change the output format to jpeg, it does the same:
ffmpeg -i 00020.MTS -vf fps=fps=1 -f image2 stills-%03d.jpeg
But there is a problem. The quality of the jpegs begin okay, but quic
