tpad
that needs to be change).-filter_complex [0:v]scale=1920:1080,tpad=start_duration=5[v];
[0:a]adelay=5s|s[a] -map [v] -map [a] -b 6000kthe 5 seconds that the movie is in its

needs to be changed from default black to some other color. Thanks. -
FFMPEG color to transparencyq
5 September 2019, by Andrew LI am trying to convert a mp4 video with a completely uniform pink color to a mov file seuch that the pink color is transparent.
I have run:
ffmpeg -i input.mp4 -vf "chromakey=0xf25b98:0.01:0" -c copy -c:v png output.mov
I confirmed that #f25b98 is the color I am replacing. This makes absolutely nothing transparent. When I try:
ffmpeg -i input.mp4 -vf "chromakey=0xf25b98:0.02:0" -c copy -c:v png output.mov
I get some weird transparent dots in my pink but still nothing is changed (see attached screenshot from video).
Why would ffmpeg exhibit this behavior?

Swscale color space convert interlaced frames?
29 May 2012, by NiorehI am writing an application that exports video that I have captured (PAL SDI). The original color space is uyvy (4:2:2). When I convert the frames with swscale to 4:2:0 and encode with avcodec I get color bleeding between the fields. I suspect this is from swscale not being aware of the frame being interlaced. Here is an example of a part of a bob-deinterlaced frame from my exported video showing one of the fields:
As you can see, the color bleeds from the other field. How do I keep this from happening? I have looked at the library and tried to find anything in swscale that tells it to respect the fields, but I haven't found anything.
I store each field in seperate buffers, so I can process the fields individually before hand if that would help.
Thankful for any help on this!
Regards
CarlEdit: Basically, what I want is to output PAL DV. I suspect swscale is able to somehow produce this type of interlaced 420, since ffmpeg (the application) can handle this (I think).
