HTML 5 workflow

[Craig Seeman]

[Craig Chapman] “So we decided to venture past flash video into HTML5 encoding.”

I assume you mean coding your webpages.
H.264 .mp4 works in both Flash and HTML5

[Craig Chapman] ” like them all to be able to play on all mobile devices.”
[Craig Chapman] “Is there a good webM video encoder/compressor?”

Android 2.3.3 and up supports WebM but that would leave out a large number of mobile devices. Given that H.264 .mp4 would work with HTML5 on both iOS and Android, I don’t see a motive for doing a WebM encode there.

On the other hand there are current browsers such as FireFox and Chrome which support HTML5 WebM rather than H.264 so that might be a motive. Of course then you get into the debate on the user of your resources. People often use Flash fallback so the same H.264 .mp4 can be served one way or another.

When you implement WebM you have to be aware you’re doubling your storage use and doubling your encoding work.

I use Telestream Episode but Squeeze would be viable for WebM as well.

Thanks for the info.

I appreciate your immediate reply. Our web developer has requested both H.264 and webm formats for his needs.

We are currently looking for a more inexpensive solution to satisfy our need for a webm or “vp8” compression.

Do you know whether Compressor 4 will encode webm or vp8?

All the specs on apple for the compressor 4 said was “H.264 encoding for Apple devices, web, and mobile devices.”

Thanks again.

Best,

Craig Chapman

It would make about as much sense as Apple developing for Android. Apple would wish WebM a speedy death.

There are inexpensive/free WebM encoders but at onetime they were most noteworthy for being seriously flawed.

I wouldn’t use them for professional use.

this isn’t true (anymore, at least.)

i just used compressor to make a vp8.
you need to install it as a quicktime component and it will show up under the quicktime codecs as vp8

(WebM Component Installer.pkg)

also check out Miro Video Converter. (donationware.)

my problem is any option i’m finding is horribly slow!
anyone know of speedier solutions?

[Ryan Welborn] “you need to install it as a quicktime component “

Quicktime component use is deprecated as Apple has moved from Quicktime kit to CoreMedia (AV Foundation).

[Ryan Welborn] “my problem is any option i’m finding is horribly slow!”

and may remain so if you’re looking at Quicktime components. There’s not a lot of market motivation for things such as hardware acceleration for both encode and decode of H.264.

Ryan,

I have installed, but it does not show up in Compressor 4.1 or 3.5.
Is there activation of some kind?
Do I need Perian in my System Preferenses?

Thanks.
