[Pro] HTLM5 video

Hi, when I go to preview my page with video on it, the music automatically plays but the image doesn’t. I have to click on the area where the image should be in order to see it. Any ideas how to fix this?

Are you previewing locally or online?

Can you post a link to your page online so that we can see it for ourselves?

I am previewing locally. I will have to publish the site first and get back to you.

I have a problem related somehow to HTLM5 video- In browsers, it plays on Macs, iPhones, iPads but not on any androids

Most often, this comes down to QuickTime being able to play almost anything at all, and limited platforms (limited by design, not omission) only being capable of decoding a small range of codecs. Make sure that your video meets this very short list of requirements:

  • H.264 video compression
  • AAC audio encoding
  • no more than 1800 bits per second data rate (less is more)
  • No spaces or punctuation besides a - or _ in the filename (before the final .mp4 or .m4v)

QuickTime 7 Pro’s Export for Web menu option gives you a nice wizard for creating just this.

Can you tell me how I would tell whether my videos meet these requirements? Is there information I can see about the videos that would reveal these things?

Did you compress them yourself? If not, then you can tell some of this (not the data rate, I don’t think) by opening the file in QuickTime 7 Player Pro and using the View / Inspector to see the inner bits. If you have access to a high-quality original (not a compressed file, or a lightly-compressed file if the raw footage isn’t available) then exporting it yourself is the one true way to get exactly the file you want. Compressing an already-compressed file is a good way to make a hash of it (crawly artifacts around high-contrast areas, often a larger file size than the original). Avoid that whenever possible.

Here’s your annual reminder to pay $30 for the most flexible video tool (a small amount of) money can buy:

You won’t be sorry. This is the Swiss Army knife of motion formats.
