Here's the situation.
I have an iPhone. Its software is updated, current.
I took a video with my iPhone. I have a youtube account for uploads. I've done this before.
But when I attempted (multiple times) to upload a very cute video (hopefully you'll see it soon), I met with this message: "Failed (invalid file format)."
So I posted to Facebook, asking for help from my 1300 closest friends. Some had to have done this, I figured, for sure. Linda responded immediately. She found this fix. You only need to see the length of the fix to understand why I am in the fist-through-the-screen mode.
iPhone. Youtube. We're not talking about knock-off phone picked up on the street in Bangkok or thirteenyearoldsvideouploadchannel.com.

Audio/Video sync issues with .MOV and .MP4 videos
How to ensure proper Audio/Video sync through a QuickTime conversion
MOV/MP4 files exported from programs such as iMovie, Final Cut Pro, and QuickTime Pro have certain elements that are not handled well by YouTube transcoding. In order to ensure optimal upload quality--and specifically that the Audio and Video of the file remain in sync--use the encoding settings outlined below.
Export your video using QuickTime
- In iMovie, select Share > Export Using QuickTime
- In Finalcut Pro, select File > Export > Using Quicktime Conversion > Options
- In QuickTime Pro, select File > Export > Export: Movie to QuickTime Movie > Options
Alter your video encoding
- Enter a name for your file, and select Movie to QuickTime Movie from the Export dropdown.
- Click Options and make the following changes to Video settings:
- Compression Type: H.264
- Frame Rate: 30 is preferred. 23.98, 24, 25, 29.97 are also acceptable.
- Data Rate: Automatic
- Key Frames: Automatic
- Frame Reordering: Unchecked
- Make the following changes to Audio or Sound settings:
- Format: AAC
- Click Show advanced settings and choose Constant Bit Rate as encoding strategy.
- Select Size and choose the original size of the video.
- The section Prepare for Internet Streaming must be set to Fast Start.
- Save your video, and then upload the resulting file to YouTube
