Rubeus. M
Is there a way to change the amount of time text is on the screen by speeding up the transition? Thanks.
hi, you could click on the link below to update the program to the latest version 5.1.1. http://download.wondershare.com/video-editor_full846.exe Then please relaunch the program, go to effect tap, you will find the Chromatic Aberation effect in the second line from the buttom.
I try to update the wondershare video editor but it sais that it is alredy updated to the latest version. I can't dind the Chromatic Aberation effect on it.
Actually, after you adjusted the speed of the video, as our program will compress the video to a lower resolution as 512*288 to set the preview window, so the playback is not smooth. But the output quality will not be affected. Please just try to export your file, and then you could check the output quality.
Never mind it's only in the preview. Once it's exported to a movie file it works fine.
I'm having a problem when speeding up a short clip it does not play the whole clip. It speeds the clip up a bit and it stops somewhere in the middle of the clip. It does not play the whole clip from beginning to end when sped up. Did I missing a setting?
Hi, please note that the " Create" button is for the old version, now, we have replaced it with "export" button. If you need to export the project file to a common video, then you just need to click the export button after finish the video editing, then go to format tap, choose the format you need, press export again to finish the whole process. You could follow below instruction to do so. http://support.wondershare.com/how-tos/how-to-export-my-work-to-a-video-file.html
