I am using FFMPEG to convert an image and an audio to a video.
I am able to achieve the final video using the following command (Attaching the output of the command too) :
time ffmpeg -loop 1 -i inputImage.jpg -i inputAudio.mp3 -c:v libx264 -
c:a copy -shortest output1.mp4

Here are the respected sizes of inputs and output:
inputImage.jpg : 160kb
inputAudio.mp3 : 380.3kb
output1.mp4 : 1.3MB
The size of output video is pretty large as compared to the input audio. This is my first issue.
Secondly, as you can see, this process takes ~30sec, which is too much I think.
How do I solve this two problems?
reducing the output video file size
reducing the time this process takes.
I've gone through numerous online links, including a lot of questions on this forum for the past several hours but still not able to solve this.
Tried playing with framerate but disturbs the duration of the output video.
Can someone please help here. Let me know if any other information is needed.
1 thing that helped me reduce the size of final video from 3MB to 1.2MB was to compress the image that I am using.
Both your issues are due to the same cause. FFmpeg has generated the video by repeating the image 647 times. Your output file has 647 video frames at 21 FPS. This info is displayed in your console output.
frame= 647 fps= 21 q=28.0 Lsize= 1302kB time=00:00:23.76 bitrate= 449.0kbits/s speed=0.778x
You can optimise this by one or more of the following ways
Decrease output video resolution (-s lower-resolution)
Decrease output video bitrate (-vb lower-video-bitrate)
Decrease output FPS (-r lower-frame-rate)

I'm trying to concatenate a bunch of png files into one mp4 file using ffmpeg. I use following command:
ffmpeg -f concat -i concat.txt -f mp4 out.mp4
The "description file" (concat.txt) looks like this:
file screen_001.png
duration 0.14538311958312988
file screen_002.png
duration 0.11382007598876953
file screen_003.png
duration 2.543360710144043
...
file screen_036.png
duration 0.15303301811218262
file screen_037.png
duration 0.160630464553833
file screen_038.png
duration 3.2751874923706055
Given command works, I'm able to create desired mp4 file. The problem is, the duration of the output file is smaller than sum of the duration lines from concat.txt. I expect mp4 file ~22.48s long but I get 19.20s long file.
What am I doing wrong? Maybe I'm not using some flag I should? Is it even possible to do what I want? I'm kind a newbie with ffmpeg and video manipulation at all so any help would be appreciated.
Output of the ffmpeg, maybe will be useful:

Create a video from each png like this:
ffmpeg -f image2 -loop 1 -i 01.png -r 30 -t 00:00:05.000 -pix_fmt yuv420p 01.mp4
Where:
"-r 30" is frame rate
"-t 00:00:05.000" is the time of this PNG in the video, in this case 5 seconds, looking this the floating point is 3 :(
Anyway, make this for each video and to concat it, create a txt:
concat.txt
file '01.mp4'
file '02.mp4'
And use ffmpeg to concat all files
ffmpeg -f concat -safe 0 -i concat.txt -c copy output.mp4
Good luck!
Edit in the docs are in microseconds too, maybe float point is 6 and not 3:
http://www.ffmpeg.org/ffmpeg-utils.html#time-duration-syntax
I am following these instructions regarding capturing and converting video from a Wear OS device, and I am running into problems. I get a video and I can tell it is my screen but it seems to be warped. This should be a green check with some white text.
There is a lot of noise when I run this:
ffmpeg -f rawvideo -vcodec rawvideo -s 400x400 -pix_fmt rgb24 -r 10 -i video.raw -an -c:v libx264 -pix_fmt yuv420p video.mp4

Any ideas?
I've tried this:
"C:\Program Files\ffmpeg-4.2.1-win64-static\bin\ffmpeg" -i %1 -i %2 -b:v 1M -y -speed 2 "%~dpn1.mp4"
"C:\Program Files\ffmpeg-4.2.1-win64-static\bin\ffmpeg" -i %1 -i %2 -pix_fmt yuv420p -vcodec libx264 -async 1 -speed 2 "%~dpn1.mp4"
Always same result. The file and quality are great, but obv since its karaoke... the lyrics need to match the timing and the converted files lyrics track is always about a full second or so ahead from when I play the original in a Karaoke program. Any ideas on what settings I could play with to help with this?
Both the original and the converted have the same play length at the end though. so the mp3 track seems to be ok.
EDIT: Added cmd output

that's your original command (though without the windows-specific bits) adjusted with a timestamp offset of 1 on the video and zero on the audio, so that the video should delay one second but the audio should not.
I am trying to make a short video in FFMPEG, where a word stays on screen for the duration of the video (0.5s). My FFMPEG code looks like this:
ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\:\Windows\fonts\calibri.ttf':fontsize=18: fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4
However, I keep getting the following error (see below for full output):
Fontconfig error: Cannot load default config file
[Parsed_drawtext_0 # 000001c2918cef00] Using "C:/Windows/fonts/mingliub.ttc"
I figured it had something to do with the path to the font file. I also tried copying the font file to my FFMPEG map and map the font path to the FFMPEG directory:
ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf
"drawtext=fontfile=‘C:\FFMPEG\bin\calibri.ttf':fontsize=18:
fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4'
This doesn't work either. I do get an output video.mp4 video, but the font is wrong. Here is the full output I get. It is the same for both code examples above:
c:\FFMPEG\bin>ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf "drawtext=fontfile= ‘c\\:\\\Windows\\\fonts\\\calibri.ttf':fontsize=18: fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text='word'" output.mp4

2019 Windows builds seem to have changed syntax or something again; here's what works for me today:
-vf "drawtext=fontfile=C\\:/Windows/fonts/consola.ttf:fontsize=72:fontcolor='white':timecode='00\:00\:00\:00':rate=25:text='TCR\:':boxcolor=0x000000AA:box=1:x=860-text_w/2:y=960"
In my case, I'm running FFmpeg from PWD not C: so I have to specify font path C:\ with escaped colon and forward-slash for path.
SOLVED! Apparently the problem was that the path to the font cannot contain a semicolon (i.e., "C:/". The code that worked is:
ffmpeg -f lavfi -i color=c=white:s=320x240:d=0.5 -vf “drawtext=fontfile= /Windows/fonts/calibri.ttf:fontsize=18: fontcolor=black:x=(w-text_w)/2:y=(h-text_h)/2:text=word” output.mp4
If you are trying to get the font using script/program, you should additionally escape backslashes.This path worked for me:
const FONT_FILE = 'C\\\\:/Windows/Fonts/arial.ttf';
I wanted to create an .mp4 video with a framerate of 1 fps out of 10 images. I followed https://trac.ffmpeg.org/wiki/Slideshow and got to (my images are in the folder I am running the command from and are name img000.png, img001.png, etc.)
path_to_ffmpeg\ffmpeg.exe -framerate 1 -i img%03d.png output.mp4
However only the first image is taken to the video and it only shows one image!
After trying multiple permutations of -framerate and -r options and positions of the options, I did not recieve any better results.
Does anyone know what might have gone wrong even in this simple case? Thanks.
