Convert 1080i (1440x1080) to 1080P (1920x1080) incl deinterlacing on Mac

[TravelRock]

Hi,
I've filmed a lot with a Sony HDV camera from circa 2005 till 2010. The best resolution the camera offered was 1080i - that is 1440x1080 interlaced.
I want to be able to upscale this with Topaz Video AI but that software does not handle interlaced video at all, which is why I need to convert the video first to 1080P - that is 1920x1080.

I've read a number of post here but from what I've found none of those solve this on Mac. I did try Hybrid on Mac but the software used is either full of bug on Mac or just not fully adapted for Mac. I also tried Handbrake but do not seem to be able to solve this on Mac at least. I think I'd prefer a standalone software, and not need to use Premiere or similar with plugins, and I know there's a number of different ways to handle the interlacing (Bob, Yadif etc).

Have anyone here a suggestion/recommendation on software for Mac you've used for deinterlacing 1080i and converting it to 1080P with optimal result?

Thanks!

Maybe ffmpeg -i "infile" -vf "yadif=mode=1, scale=1920:1080" -c:v libx264 "outfile"?

For same frame rate, it's mode=0, for double frame rate (bobbing) it's mode=1.

Yeah, I just tried Handbrake and maybe this is also possible but that program is just stupid with assumptions what the user wants to do regarding resolution, resizing and aspect ratio.
No wonder why you gave up on it.

Thanks a lot @Badyu17
Trying that out now!

However I get this message now and then during the process... is this something indicating the output will have issues or can it be ignored?

Hi,
Being a new to this kind of video conversion without GUI and to FFMPEG I hope I can ask how I should interpret this. Did all go well or do I need to adjust something and run again?

Considering below output... should I adjust anything else if I want to stay close to original quality?
(Overall bitrate on converted fils is: 6 434 kb/s, on source 26.1 Mb/s, perhaps that is something I should change?)

x264 default is crf 23, that's why your file size is lower. Add this to your command

-c:v libx264 -preset slow -crf 18 (experiment with crf 18-21)

And you'll get higher bitrate and better quality. As for ffmpeg warnings that's probably something how the original footage was encoded in mpeg-2.
If your video plays ok you can ignore it.

Thanks for your fast and informative reply badyu17, really appreciated a lot!!! Will try your suggestion right away.
