Hi,
I am looking now for a "fast start" option in Compressor 4 for .MP4 H264/AAC encoded files.
Is there a way to do that ?
Thanks
Eric
iPhone 4, iOS 5.0.1
I use Amazon CloudFront streaming for my .MP4 files
It's RTMP with HTML5 fallback if RTMP isn't supported (iPhones…).
I notice a small latency at start, so is there a faststart option when encoding files with Compressor ?
Any suggestions ?
Thanks for your help
Eric
Eric,
See if this works for you. Start with the Broadband High preset (you could use any preset). Open the Encoder pane; in File Format, choose Quick Time; Click on Video Settings and in Compression Settings, select H.264. Set your data and then Optimize for streaming. Return to Encoder and open Audio settings to specify thge format you want; In the Encoder, select Streaming and then select Fast Start. In the Extension box, change the extension from .mov to .mp4. You should wind up with a MP4 H.264 CBR preset.
Good luck.

As I have a French user inerface, I am not sure of what I have to do…
But "Optimize for streaming" is only for QuickTime Streaming Server compability, no ?
Am I wrong ?
It's an odd workaround, but that optimize streming selection is the only way I was able to get a constant bit rate with Fast Start available in the Encoder panel. Hope you're able to translate and the settings work for you.
Good luck.

With this workaround (if I did it well...) I get much much rapid start on my iPhone (HTTP Streaming) than previoulsly, but on PC web browsers the stream (RTMP) isn't played.
😢
I get a JW Player message saying "Stream not found : my_movie.mp4"
As the file is on server, I think that it's not recognized as a valid compatible RTMP file...
Sounds logical for you ?
Eric…I honestly don't know the answer. From this point out, I'd only be guessing.
The only thing that I can think of suggesting is that you summarize your issue and post in the Compression Techniques forumat Creative Cow. There are people there who are more experienced in cross-platfom issues.
Again, good luck.
