Advertisements I'm pleased to report that I've had my first success in encoding a MPEG-2 video to MPEG-4 and playing it on my Tivo through Tivostream. I managed to get Roxio's Toast 9 Titanium for Mac to do the job through a customer setting. I'm currently encoding another video now so I can't list every thing I did but here's the basics. The first thing I did was looked a little closer at the sample Revision 3 video that we all use for testing. According to the Apple Quicktime player, this is a 720p video that is encoded for H.264. The data rate is 2164 kbits and uses a standard 2 channel AAC soundtrack. Outside of that, nothing about it seems that remarkable. Test video was the Pixar short "Jack Jack Attacks" from "The Incredibles" Bonus DVD. It was originally ripped with Mac The Ripper to my central Leopard Server in my home. Custom setting: 1. Use the generic H.264 player instead of the pre-made settings for Apple products, like Apple TV. 2. I used a 2000 kbits data rate 3. I just had it optimized for download, not streaming. 4. Single pass encoding (I'm testing a multipass encode right now and will report if it works or not) 5. Optimized for server (there's a special "video" button that reveals this feature" 6. Audio. Two channel AAC, 48kbits. 7. Resolution. At first I tried to match the native resolution of the DVD, which is a 720 x 580 setting (anamorphic widescreen). But for reasons I don't understand, that setting, while it played on the Tivo, had a weird jutter problem in playback that made watching the video difficult. So I tried upscaling to 1080p. This looked and played far better, both on my 1080i RPTV and my 480i standard def bedroom television. Today, I'll experiment with my more settings (whether encoding for streaming makes a difference or not, other encoding tweaks). One thing that would be nice to do is 5.1 sound (required for me to be happy with doing it for my home theater) but even though it's possible to encode AC3 audio in a H.264 video, whether the Tivo willl play it back properly is a big mystery. Handbrake has a setting for this but I'm not sure that Toast does. Also, I'm not sure the data rate is going to be optimal for a 1080p encode...I have some 1080p movie trailers which I will look at again to check what their data rate is. And I'm sure that 480p trailers of the same movie trailers have a lesser rate.
