Creating farms of unique websites

setting bit rates in creating video from images in ffmpeg not working
2 mai 2014, par mast kalandarI have a HQ video of one second
Some information of this video is as below
Dimensions : 1920 x 1080
Codec : H.264
Framerate : 30 frames per second
Size : 684.7 kB (6,84,673 bytes)
Bitrates : 5458 kbpsI have extracted frames from video
ffmpeg -i f1.mp4 f%d.jpg
All images are of 1920 x 1020 pixels by default 30 frames are generated (f7_1.jpg, f7_2.jpg,.....,f7_30.jpg)
I have added some texts and objects to these images (without changing dimensions of any image, all 30 images are still of 1920 x 1020 pixels)
Now I am trying to merge all these images to create single video (of 1 second)
I referred this official document, I have run below command
ffmpeg -f image2 -i f7_%d.jpg -r 30 -b:v 5458k foo_5458_2.mp4
Video created is also of one second, thing is its bit rates are higher then the original one. New video has 6091 kbps bit rates, while I expect are 5458 kbps only.
Because of higher bits, its gets finish very quickly compare to original video in video player.
Is there any thing I missing ??
And I don’t know what is exact meaning and job of
-f image2
option, when I run command without this option, I am getting same video. -
FFMPEG - convert video without losing resolution
20 février 2020, par SrhI am using ffmpeg to convert mp4 video from youtube. The video is HD 1080. When I convert it to mpeg2video, the video loses its sharpness, regardless of the
-s 1920x1080
parameter. How can I convert the video without losing picture sharpness ? The command I use is :ffmpeg -i BBB.mp4 -vcodec mpeg2video -s1920x1080 -acodec copy -f mpegts BBB.ts
