I am a Digital Photography teacher, but not a video expert. I have a student creating some amazing video work using filters in Adobe Photoshop and the video functions. Her clips are usually between 45 seconds and 2 minutes in length.
Recently, she is having an issue where her videos seem to not fully render for playback. Because of this, she is having issues with the video skipping frames. Additionally, when she tries to export the video, she will be left with parts of the video and mini skips throughout where the missing frame were located.
