ffmpeg overlay fadein/fadeout is not working [duplicate]
22 avril 2021, par user15602767This is my normal overlay filter without any fadein/fadeout


ffmpeg -i .\urban_pop_b4.mp4 -i .\logos\cfe-coffee.png -filter_complex "overlay=700:300:enable=between(t\,3\,6)" output.mp4



When I include the fade-in/fade-out option as in docs I dont get any overlay at all(no error thrown)


ffmpeg -i .\urban_pop_b4.mp4 -i .\logos\cfe-coffee.png -filter_complex "[1:v]fade=t=in:st=5:d=1,fade=t=out:st=10:d=1[over];[0:v][over]overlay=700:300:enable=between(t\,3\,6)" output.mp4

Already tried out ffmpeg overlay image with fade in and fade out

Superimposing two videos onto a static image ?
15 décembre 2014, par ArchagonI have two videos that I’d like to combine into a single video, in which both videos would sit on top of a static background image. (Think something like this.) My requirements are that the software I use is free, that it runs on OSX, and that I don’t have to re-encode my videos an excessive number of times. I’d also like to be able to perform this operation from the command line or via script, since I’ll be doing it a lot. (But this isn’t strictly necessary.)
I tried fiddling with ffmpeg for a couple of hours, but it just doesn’t seem very well suited for post-processing. I could potentially hack something together via the overlay feature, but so far I haven’t figured out how to do it, aside from pain-stakingly converting the image to a video (which takes 2x as long as the length of my videos !) and then superimposing the two videos onto it in another rendering step.
Any tips ? Thank you !
Update :
Thanks to LordNeckbeard’s help, I was able to achieve my desired result with a single ffmpeg call ! Unfortunately, encoding is quite slow, taking 6 seconds to encode 1 second of video. I believe this is caused by the background image. Any tips on speeding up encoding ? Here’s the ffmpeg log :

Update 2 :
It works ! One important tweak was to move the underlay.png input to the end of the input list. This increased performance substantially. Here’s my final ffmpeg call. (The maps at the end aren’t required for this particular arrangement, but I sometimes have a few extra audio inputs that I want to map to my output.)

Time FFMPEG takes to encode a video file
1er avril 2020, par amateurI have recently been working with FFMPEG to do some manipulation on video files, becoming aware of the syntax etc and have found it very helpful. I am looking for some feedback though on the speed it takes to encode file. For example, I run the following command against a video file, 1 hour in length, file extension .mov and 4GB in size, and the command takes just over 4 hours to run. It produces a file 2.2GB in size. I am running it on a high spec i7 laptop.



ffmpeg -i "C:\MyInputFile.mov" -b:v 4500k -bufsize 4500k -r 50 -bsf:a aac_adtstoasc -vf scale=1920:1080 "C:\MyOutputFile.mp4"

Please see following the log created at the start of the encoding. I dont have the full log unless I let it run again for 4 hours!
