I made a short animated video from a template explaining who I am for my customers. I would like to put the video on Youtube or Vimeo so they know a bit more about me, but I am having trouble exporting it from Adobe After Effects. Everytime I export it, it is chopping and missing frames. The quality is good but it's not fluent. I've looked all over the internet for answers but I just can't seem to find one. If someone could help me but sending some screenshots, video's, or articles my way, that would be great.
You need to read up on rendering. The best solution is to use the Adobe media encoder her and pick a YouTube or Vimeo preset that matches your composition settings.
The third video talks about rendering.
