AE export makes video square

Hoping someone can help me I haven't found a solution anywhere on the web.

Im running latest After Effects.  When I import a 4K video and do color correction I go to Compisition, add to render que, and export from output module as QuickTime h.264. First couple times it worked beautifully but suddenly I got the caution message during one of the renders that the format would be changed from 4K to 2000 by 2000 (par 1.22) to meet format constraints.

My final picture is then square instead of 16:9 when playing back in QuickTime. Is there a way to keep the video in 16:9 or bypass the downgrade to meet format constraints?

    When i I add to render que in AE the out put module sets it to QuickTime DV NTSC 48khz. I click on output module and change format options to h.264 and the caution reads warning: out put file will be resized to 2000x2000 (1.00 par) to meet format constraints. Final rendered picture is square instead of 16:9.

    Why on earth are you rendering in SD video when your footage (I presume) and comp are in 4K?  That just doesn't make any sense.


    Your choice for an output codec makes no sense. Just choose Uncompressed from the settings in the Output Module of the render cue or pick h.264 in the Adobe Media Encoder and use one of the presets.

    Don't go messing with render settings until you understand them.

    I recommend that you output to Adobe Media Encoder. In there there are several presets that will help you. The first thing to consider is what are you outputting this video for? Is it for showing in a digital cinema or on a 4K TV? If so then you may want to output 4K but H264 is the wrong codec for that. if you want to output for YouTube or Vimeo or the web the. H264 is fine but choosing the correct settings for each purpose is important. So, Go to File > Esporta > Adobe Media Encoder. When your comp appears in AME, drag the YouTube preset you want (or other preset) from the list onto the comp. I'd suggest trying the YouTube 1080 preset to start with. This will output a 16:9 HD movie.

    good luck :-)

      I just want to say thanks. I was having the same issue and I tried every setting and nothing worked until I used Encoder.

        We need to know exactly what render settings you are using. You should be using a AME template unless you are expert in compression and formats. Some formats are extremely picky about frame sizes and frame rates.

        I've been rendering in AE not the Adobe Media Encoder. the render settings are QuickTime h.264 frame rate 23.976. Is there more info I should be looking at. I'm definitely not an expert so thank you and I'll get any other info you may need to help.

        Work in a comp with square pixels -- the horizontal & vertical dimensions that your video SHOULD be, but because the camera maker cheaped out, are probably 75% fewer horizontally than you'd expect.  Maybe even 66.666...% fewer.
