This is a big mistake. You should not be editing this. Near the top of your post, you said the Video Mode is already “UHD2160p 23.98,” but it is not in this project. This project is 1080p60. The video mode that is selected when no project is loaded is irrelevant to a saved project; that is for new projects. When the project is open, use Settings > Video Mode instead of editing Export > Advanced. After you make this change you do need to review the entire project because you changed something rather fundamental to the project. In the future the very first thing you should think about and set is the Video Mode.

which is the part clip that from phone

That usually means the video is variable frame rate, not safe for editing, and needs to be converted using Properties > Convert.

I cant find the AI fie

I do not know anything about an “AI” file as a solution, but Shotcut does not read Adobe Illustrator files.

Besides converting the problem video as explained above, another thing to try is to remove that part of the timeline and recreate it or to simply place something on an upper video track in that part.

You did not state where in the timeline the black video part appears using a timecode value and its duration. I will try to load your project with my media when I get that information.

I have tried place on the upper video track that is not working for me. I will try couple of clips for recreate.
duration of black part 1 from 00:00:03:00 to 00:00:06:57, and part 2 from 00:00:11:00 to 00:01:01:33.
thank you for your time.

You need to correct the video mode and stop changing things in Export > Advanced before I will take a look at this further.

i selected 4k video mode before i open the fie, then it changed back to 1080. Ive changed to 4k again but video are cropped.

here is some additional situation im not sure if it will help you to better. there was shotcut no responding happened a lot when i editing, so shotcut has been forced to stop. after i chose auto recover then where the black video were went black in the timeline. I’ve changed property-video-track from none to the video track. it just happened again so it reminded me.

I cannot tell anything from the log. Did you export without changing Export > Advanced?
Please check Properties > Video > Track on the clips with black video. If you do not find a problem on them, then upload the latest version of the project and give the timecodes for the black segments.

I just fund out whats the problem. i changed the color range in the properties to mpeg from peg. so now is ok.

thank you so much. i was going to change others for next editing. But now im going to keep use shotcut just because of how excellent you have been gave me so much more confident to continue use it. I’m really appreciate.
