Issues for Uploading FLV to YouTube

Can you upload FLV to YouTube? Let's look at Supported YouTube file formats as shown below first.

Make sure that you're using one of the following formats:

Here we list three typical situations for reference only.

Situation 1 I was playing Unhack, a game that does not agree with Bandicam so I swapped to OBS, it recorded my videos in .flv format. When I tried to upload the FLV videos to YouTube, I got a message "Invalid File Format" or "Upload Failed".

Situation 2 I used Camtasia Studio to record a tutorial with FLV extension and then uploaded this tutorial to YouTube for share. However, a message "Upload Failed" pops up. Why? I'm using Camtasia 7.

Situation 3 I successfully downloaded a movie in .flv from YouTube and then extract the source audio and add another audio file which I record by microphone with a wonderful tool to the movie. The movie is still FLV format. However, it failed when I uploaded the movie to YouTube again.

In fact, FLV has been adopted as the default online video format by many sites, including YouTube. YouTube only accepts FLV encoded with Adobe-FLV1 video codec and MP3 and AAC audio. However, FLV is a container format, which may contain various kinds of video and audio codec and data. Once your FLV videos are not in accordance with the above requirements, you will get the "Upload Failed" message, for example, audio in Flash Video FLV files recorded from the user's microphone use the proprietary Nellymoser Asao Codec.
