Sir,
We are using handbrake to add subtitles to video. As suggested in the forum earlier we had sucess in adding UTF-8 fonts
But We are seeing the sound quality very poor and the video now and then jumps all of a sudden it is not transistioning smoothly. it stops for a while and jumps.

I used the following code.
ffmpeg -i 1056.mp4 -i 1056_tel.ass -codec copy -s 720X480 -b:v 494k -b:a 192k temp.mkv
handbrakecli --subtitle 1 --subtitle-burned -i temp.mkv --rate 3 --quality 20 --ab 192k --optimize --width 720 --height 480 -o telugu1056.mp4

it didnot help me . then i did google search and used the following code

ffmpeg -i 1056.mp4 -i 1056_tel.ass -codec copy -s 720X480 -b:v 494k -b:a 192k temp.mkv

handbrakecli --input temp.mkv --subtitle 1 --subtitle-burned --output telugu1056_v1.mp4 --rate 29.97 --arate 44.1 --vfr --vb 494k --ab 61.6k --custom-anamorphic --optimize --width 720 --height 480 --mixdown stereo -x bitrate=5200:vbv-bufsize=5200:vbv-maxrate=5200:level=42:bframes=2:min-keyint=60:keyint=60:ref=4:me=umh:merange=64ubme=7:8x8dct:cabac=1 -v3 -2 -a none

del temp.mkv


due to the above code audio is not heard at all. earlier atleast some audio is there with poor quality. now it is completely lost.


I am not sure what to do.
We want to add UTF-8 subttiles to a video at a higher font size, hence as we are using both ffmpeg and hand brake as advised by the forum members.
