Into TVAI shown resolution does not fit output resolution

TVAI 7.0.2
Not a big deal but incomprehensible. If source is 864 x 486 (<- is excatly 16/9) and doing for example 3x, the shown resolution into TVAI is correctly 2592 x 1458, but then the output it does is 2592 x 1456 which is not exactly 16:9, so this makes no sense. TVAI sets a DAR 16:9, means the video gets streched by 2 pixels when play :smirking_face:

The worm must be somewhere deep inside and probably has something to do with 16:9 SD sources in 720x404 format which is rounded up or down because it’s not excat 16:9 and gives floating points, it seems to be this mechanism works also here where it shouldn’t

I do not attach logs because I checked it and there is nothing inside, it just say upcaling to 2592 x 1456. You can replicate this with every 864 x 486 source

left: running output shows correctly 2592 x 1458, right: output what it did is 1456 instead 1458
(2592 / 16 x 9 = 1458)

if this cannot be corrected for whatever reason, at least the resolution displayed in TVAI should correspond to the output

Does the original source file show the option to be seen with the choice of pixel type?

I dont’ have the mpeg-2 orig source it snot a square pixel theme. In generally the question here is why TVAI does resize progressive 864 x 486 source to 2592 x 1456 instead 2592 x 1458

it’s simple math, this is just a sample. Could there be more cases simillar happens?! I just don’t understand why, because numbers are divisible by two, source format is exactly 16:9 and the upscale from source to target size does not generate any floating points.
