For PNG you can use -compression_level. Range is 0-100. Default is 100

Thank you for your help!
The fact is taht when using hardware encoder and you set mux rate to
20Mbit/s and video to 2Mbit/s the space between 2 Mbit and 20 Mbit/s will
be filled with null packets, this is not in this case.
Now I reduced Mux rate and it is not exceeded by the tests I did with TS
After a long break from this issue, I have a new problem. For
example, I want to take a 24fps video and make it play slow-mo at
12fps. The input option -r is dropping frames, rather than slowing
down the playback speed. I don't have my main computer right now,
which uses the latest git master;
Ah yes of course, I had the numbers mixed up in my head. Thanks Nick.
Now when I do the conversion, I get all these non-monotonous DTS
warnings. Is there any solution to that, other than reducing the
loglevel? The output file seems to be correct, albeit without a
timecode track. Timecode is

When outputting frames like this, is there a way to put the frame
number/time in the output file name? Otherwise, it looks like I have to use
the drawtext filter to add it to the images.
Sure.

This creates one image for each second of video:

When I change the output format to jpeg, it does the same:

Hi,
I am not sure if anyone asked this kind of question before.
Now I want to build a system with one In and N outs with FFMPEG.
The system likes below:

Actually, you meant my -map [0:a]. Sorry, my bad.
There _should_ also be some way to encode your audio only once, since
both your encodings are identical. Someone

Dear All,
I've been trying to achive constant video bitrate for mpeg-2 with different
settings of ffmpeg (windows) but no success.
The source was dshow.
I've been testing video bitrate with TS reader.
Can you tell me if video CBR in
f:/ffmpeg/bin/ffmpeg.exe -f dshow -video_size 720x576 -framerate 25

2000k -bufsize
Thanks Moritz,
Below are the all outputs. Maybe one filter_complex can feed all filters, but I
do not have much experience about how to make it.
[root@cdn ffmpeg_dev]# ./ffmpeg -input.mp4 -i logo.png -filter_complex
Thanks Moritz,

On Thu,
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
