Hello, I''m having 3 categories of videos , one header , main video and one footer. Headers and footers videos are already on amazon s3. I want a user to be able to choose between the header , footer , and a main video which he choose to upload and the output to be a merged video of these three. Would you recommend a correct approach , a gem , a library i could use for that. Thanks in advance for any help. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
