ffmpeg - seamless crossfade loop for the part of video
14 janvier 2021, par Flamin GOI need to apply crossfade to the last X frames of a video with the first X frames in order to obtain a seamless loop, but making this for the necessary part of video.


Here's the answer for looping the entire video.


Currently what I have :
(Whole video duration = 25. Cutted (result) part = 15 sec (from 5 to 20 sec pos). Transition = 1 sec.)


ffmpeg -i input.mp4 -ss 5 -to 20 -filter_complex
 "[0]split[body][pre];
 [pre]trim=duration=1,format=yuva420p,fade=d=1:alpha=1,setpts=PTS+( (15+(5-1)) /TB)[jt];
 [body]trim=1,setpts=PTS-STARTPTS[main];
 [main][jt]overlay" -c:v libx264 -preset veryslow -b:v 2500K output.mp4
 



In this case, everything works, but at the end of the resulting video, a piece from the original video is superimposed, which starts from 0 to 1 second, and not from 4 to 5 seconds of the original video, as it should be.


I read the official ffmpeg documentation, tried some actions on "start/end" parameters for "trim/fade" with changing of "setpts", but I always got just another batch of bugs.

16 juillet 2019, par Gopinathan BI am able to produce Fade In & Fade Out transition effect for single video file. I am fail to get other transition effects for single video. Some of the transition commands are not correct. There is no official documentation to do.
This will fade in video for 5 sec in start.
"-y", "-i", masterVideoFile!!.absolutePath, "-acodec", "copy", "-vf", "fade=t=in:st=0:d=5", outputFile.absolutePath
This will fade out video for 5 sec in end.
"-y", "-i", masterVideoFile!!.absolutePath, "-acodec", "copy", "-vf", "fade=t=out:st=$finalTime:d=5", outputFile.absolutePath
I need video to transition from Right to Left, Left to Right, Top to Bottom & Bottom to Top and start playing video afterwards.

but it is taking too long, like my speed is 10 MBps(80 mbps) size is 300MB, should be done in 30 seconds, but it takes upto 5-10 minutes sometimes, now I know it does some converting thing


My question is is there any way to increase its speed ??
I have CPU- AMD Ryzen 5600H and
GPU - NVIDIA RTX 3050


Some help will be really appreciated


I checked some nvidia encoding and decoding things from there official website and tried many things from there but always stuck at some error
