I assume that it’s either a bug of a misconfiguration of the exporting of a video.
The problem I’m facing is following:
- I uploaded several videos to Google Photos
- single one of them was in the horisontal (portrait) mode, so in the video I have to either soom/crop/resize or add black zones etc. I decided to go with black zones
- all videos have miltiplication of Speed (in Properties) same for all.
- all videos have mute and stabilize filters
- I added a soundtrack over it and cut it to the same end as video
- then export video… where I set parameters to following:
movflags=+faststart preset=fast pix_fmt=nv12 f=mp4 acodec=aac channels=2 ar=48000 ab=384k vcodec=h264_videotoolbox vb=12M g=15 bf=3 width=720 height=1280 aspect=0.5625 progressive=1 top_field_first=2 deinterlace_method=yadif rescale=bilinear threads=3
and in result I get the following picture with actually streaming video (the picture changes) and audio is correct (not distorted), but the encoding seems incorrect - the lines of the video are like shifted in position by X axis line-by-line.
Here’s the fprobe of one of the “portrait” videos:

What am I doing wrong ?
That explanation is exactly what I discovered. I’ve been using Automatic in all cases, so it was taking the first video as example. But still, it doesn’t seem clear for me from technical side why first adding landscape, then portrait videos produces expected result while the opposite way - first portrait, second landscape - produces such encoding issue.
