Hello All,
I am having a Program stream which has progressive sequence. I want to
convert this stream to Field based PS files.
I have used the following command
ffmpeg.exe -y -i INPUT -c:v mpeg2video -flags +ildct+ilme -vf yadif=1 -top
1 -b:a 256k -aspect 16:9 OUTPUT
But this is creating Frame based interlaced stream.
Looks like I have missed some options. Can you please help me fix this
problem?
Hi Vikram,
What do you expect? If the source is progressive, an interlaced output will
have two fields taken at the same time, thus still look progressive.
If the framerate does not change, besides doing this for being compatible
with streams that must be interlaced, there is no reason to do so.
If you do want to change the framerate (eg from 50p to 25i, or add
pulldown), there is logic. Have a look at the Tinterlace filter.
hth,
Bouke
Regards,
Vikram
