done thnx you

 but  other problem:  iphone is not supporting  to  filter effect on phone
when im joining(merging) video...

 ffmpeg -i video.mp4 -filter:v "fade=in:color=white:st=5:d=1,
fade=out:color=white:st=44:d=1,format=yuv420p"  filtered.mp4

ffmpeg -i intro.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp1.ts
ffmpeg -i filtered .mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts temp2.ts

ffmpeg -i "concat:temp1.ts|temp2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

when i am sending  output.mp4  video via  whatsapp. then  android users can
see all part of video but iphone user  cant see filtered affected part.
iphone user is hearing only audio of filtered video.

now whats problem?

thank you.
