can’t render mpeg2 at larger height beyond 1088pixels
exporting from AE to AME to render 768×1377 mpeg2, where 768 is the width and 1377 the height. AME will not let me change the resolution larger than 1088. anyone know of a workaround or recommend a mpeg2 converter that is resolution independent.
thanks in advance!

I just need to deliver an mpeg2 file using those dimensions. I’m basically scaling down a 1080p file and making it vertical orientation. But when I go to render in AME it doesn’t like the height of 1377 and maxes out at 1088 so it creates a 608×1088.is there an mpeg2 conversion software you could recommend that would allow resolution independence?

MPEG2 is generally supposed to conform to some pretty rigorous profiles to ensure playback compatibility.
That said, ffmpeg should successfully make non-compliant MPEG2 at weird resolutions.

i’ve been playing around with ffmpeg and the avanti gui and i can’t get it to work. can i just hire you to convert it for me? such a small thing, that’s becoming a headache. or do you have any other suggestions for mpeg2 converters?

the playback device is a windows based computer, but they are requesting mpeg2 for some reason. any ideas? i’m not sure how the end user’s system is set up.

thanks dave. i appreciate the help. i have asked my producer to put me in touch with the technical person in charge of the playback and have been waiting to hear back. in the mean time i’ve been trying to do what i can, in case there was an straight forward solution.

[dave ko] “AME will not let me change the resolution larger than 1088.”
That is because MPEG2 is not specced for that. The max resolution seems to be 1920×1088. You can try and make some weird resolutions with whatever software but there’s a chance that it won’t work as it’s supposed to. The codec specs are there for a reason.

[Dave LaRonde] “Oh. What is being used to play this file back? I suspect it’s a standard playback device, which means it expects to see a standard mpeg2 file. To put it into a vertical orientation, you and the client agree on which way to rotate the monitor: clockwise or counterdclockwise. Or you can simply make TWO versions: one with the top on the left, the other with the top on the right. Then the client can’t screw it up.”
Great advice. Portrait (vertical) video is almost always delivered as sideways landscape (horizontal) video.
As Dave says, this is a conversation you need to have with a technician on the display side.
Also, you may not need to make the file at the crazy 1366×768 resolution yourself; the player or the display may be able to scale live from your 1080p source. Another question for the display tech.

Thanks. I work primarily in the broadcast realm so these specialized display monitors with strange resolutions are somewhat new to me. So waiting to hear back from the producer but I did deliver them at left and right rotated version in landscape orientation. So we we’ll see. Strange that you can render all sorts of strange resolutions in other codecs but mpeg2 is so picky. Thanks again everyone. But just it of curiosity if anyone figures out a way to render or convert to 768×1366 as an MPEG2,i’d be very interested.
