Hi, I observe the following problem in Videopad Video Editor.
I have recorded a screen capture with OBS Studio in resolution 1920 x 1080, encoder x264 software, and .mp4 format. The video has two black bands left and right, and only contains information in the central part, which is 607 x 1080 (aspect ratio 9:16 instead of 16:9). The video looks perfectly sharp in VLC player and Windows Media player.
If I export that 1920 x 1080 video in Videopad with lossless option (basically without any operations on it), or even with other output settings, the output result is always sharp.
However, when I apply the Video effect "Crop to aspect ratio 9:16" (to get rid of the black bands left and right), and I export that video, I get serious blurring. I tried different settings (automatch content 607 x 1080) and pre-sets like YouTube video - vertical content (9:16), but nothing helps. Blurring should not happen, because the information in the central 1/3 vertical band of the 1920 x 1080 is unchanged, only the black side-bands are removed.
I know from reading previous posts that sometimes also the export from OBS Studio is a problem, but for the non-cropped video, the conversion is fine. I also checked other suggestions, like cleaning the cache files, knowing that the preview window can be blurred, etc., but those are not the causes. Also changing the framerate did not help.
I can upload an example video where the problem is illustrated, but I do not know where to put the files.
Thank you in advance,
Wim
