How to create a Interlaced Video with FFMPEG?

[franvlza]

This image shows a interlaced video vs progressive video..


I tried to convert a video (mp4, ts, etc.) to MPEG2 format (Vob, Mpeg) but Interlaced video.. I used this:

ffmpeg -i "video.mp4" -f dvd -vcodec mpeg2video -flags +ilme -b:v .. -r .. -s.. -acodec... -b:a ... -ar... "output.mpg" and yes, i have a "interlaced video"



But when i play the video the lines of interlaced dont appear.. why? how to show these lines? (its that i want) what i do wrong? please help me, thanks!

So you have a progressive video and you want to make it look interlaced for artistic effect or do I misunderstand?

You encoded it as interlaced but the content is still progressive.

how to show these lines?

Don't know, don't care, as it's a ridiculous idea. Actually, I do know but don't use FFMPEG and wouldn't do it anyway.

If it is for artistic purposes why would it be ridiculous?

Video has a lot to do with creativity surely it is not all about avisynth scripts right?

But you can't interpolate the rate (as in generating new "in between" frames with optical flow) with ffmpeg alone (yet). Unless he started with 59.94p video, he won't be able to make it interlaced content.

crop/remove one horizontal row of pixels, and then swap top field for bottom field
no i don't know the command structure
and personally.. i think it looks terrible
