All my videos always come out very pixelated. I try to make them on my s10 mobile. Any idea why? When i make videos they are clear but when edited in powerdirector they are no longer clear.
Are you saying that the Produced videos are clear but while editing the videos are pixelated? If this is the case, PowerDirector automatically scales down the preview quality in an effort to improve the editing experience. If the app had to edit the video at it's full quality the program would be bogged down to a slow crawl. The decrease in resolution or quality allows you to edit at a faster pace.
If you are saying that your video is produced at a lower quality follow the great advice that optodata already provided.
