mpeg2 MP@ML with ffmpeg

[rullbandspelare]

Hi!
I want to convert videos to mpeg2 Main Profile Main Layer, (mp@ml) , with the use of ffmpeg.
What arguments would i need to use?

Is this adequate:
ffmpeg -i video.avi -r 25 -vcodec mpeg2video -acodec mp3 -r 4000k -s 720x576 video.mp2


OR is there a predefined argument for this, something like "-target mp@ml".
Thanks for any input!

If you can write even a very simple AviSynth script you could easily do this in HCenc. In fact I really do not understand why you would prefer the ffmpeg method to using HCenc unless you are not on Windows. I just finished an encode yesterday to MEPG-2 MP@HL using HCenc that I intend to use on a BluRay disc I am burning.

Thanks for the tip!
I took a quick look and i doubt that it would fit my purposes. Have to look closer.
I am using ffmpeg for command line scripting. I prefer to use ffmpeg.

Thanks!

HCEnc is probably highest quality MPEG-2 encoder avaiable as freeware - ffmpeg encoding quality is much lower.

You can try the -profile:v 4 command for which MediaInfo gives main@main.

I know it's an old post - but it was a current issue to me, so here's what I found.

MPEG-2 profile codes in ffmpeg (from avcodec.h):

#define FF_PROFILE_MPEG2_422    0
#define FF_PROFILE_MPEG2_HIGH   1
#define FF_PROFILE_MPEG2_SS     2
#define FF_PROFILE_MPEG2_SNR_SCALABLE  3
#define FF_PROFILE_MPEG2_MAIN   4
#define FF_PROFILE_MPEG2_SIMPLE 5

MPEG-2 level codes in ffmpeg (from mpeg12enc.c):
4:2:2 profile

avctx->level = 5; /* Main */
avctx->level = 2; /* High */

All other profiles

avctx->level = 8; /* Main */
avctx->level = 6; /* High 1440 */
avctx->level = 4; /* High */

MP@ML would be -profile:v 4 -level:v 8

Verify with mediainfo (Main@Main) or ffprobe (lists profile Main, but level only as number again).

This is fragile info as I couldn't find any documentation - just the (undocumented) source code.
