ffmpeg converting .vob to .mp4 --- colors are washed out
28 mai 2021, par BlattlaI am very new to ffmpeg. Currently I am trying to convert old family movies from vob to mp4.
After getting some help I used this command :


ffmpeg -i 1998.vob -codec:v libx264 -crf 17 -pix_fmt yuv420p -codec:a aac -movflags +faststart 1998.mp4



Two things that still bug me. The output is almost 20% larger than the input and the colors are washed out. Although the movies are old and of low quality (grainy, rather flat colors, ...) the colors in the output movie are less intense than in the original one. Larger file size would be ok for me but do you have any idea which part of my command might cause the color issue ?

Getting small file size from ffmpeg [duplicate]
20 février 2020, par sukachI am not an ffmpeg expert. I am trying to get some movies converted to a smaller DIVX file for a cheap portable DVD player for a family trip. The movies are for my kids so I’m not too concerned about quality.
The DVD player is a 10.1", 1024x600 screen. It says it supports DIVX/MPEG2 files. It took me a lot of experimentation to get the right ffmpeg settings to even get it to work, but I found another answer that provided a very complex set of parameters that ultimately worked.
I have converted about 20 movies with this setting and every one results in a file size of 1.1GB. I have tried different file sizes and crf settings and it is the same every time.
Here is an example. First, the original file :
