H264 not exporting the right size

[farcasa34119014]

Im working for a client that needs the video frame size 1571x2000 .mp4.

Everything works good until I want to export the video.

When I choose h264 the exported size changed to 1570 x 2000.

( for example if i change sequence size to 1572 x 2000 and than export the exported video is 1572 x 2000 as expected ) .

Not all frame sizes are supported by the H.264 codec. If i remember correctly odd numbers such as 1,3,5,7,9 are not supported and that explains why 1571 is changed to 1570.

There is a detailed explanation out there but i don´t have the time to find it for you right now.

Averdahl is correct. To put it simply, H.264 compression encodes pixels in groups or matrixes, for instance maybe 8x8 pixels at a time. ODD numbers just don't work out, sorry. Not sure why your client would need such an oddball size, perhaps they can or should change the specification of what they want.
