Best video format to encode for playback on iBook G4 1.2GHz?
I have been scratching my head for a week on this. What is the best video format that is highest quality and will playback smoothly on my iBook g4 and my iPhone 4? It has 1.25GB of RAM and I upgraded the HD to a WD 250GB 5400 RPM IDE drive 2 years ago and it's running dual boot Leopard 10.5.8 and Tiger 10.4.11 (keeping Tiger for Classic Mode).
I have a very large HD video collection consisting of 720p HD DVDs and 1080p Bluray discs that I have already spent a year to convert to MKV and MP4 files for storage on my media server. They have all been ripped and encoded with H264 using Handbrake. The average 720p movie is about 4.5GB and the average 1080p movies run about 8GB. I have over 100 movies stored on my media server and they playback fine on all my computers. They work fine on all my Windows 7 systems, they even play fine on my G5 2.0GHz DC late 2005 Powermac with 8.5GB Ram and the NVidia 7800GT.
Most of my 720p files can be reduced in size and or quality to 1-2GB and are playable on my iPhone 4, iPad 2 and even my little Acer Aspire One netbook in m4v or mp4 format.
I know my iBook is out of date, but no matter what compression method I have tried, the only thing it can play is MPEG-2 encoded media. And it cannot handle any h264 video I make, even at 480p settings using the simple profile. Since MPEG-2 takes 4-8GB per movie, this is a huge waste of HD space. And if I encode my movies like the old iPod video size, it looks like crap in full screen. I really want to store about 20 movies on this iBook for playback when I travel since I have 2 extra batteries. I need to movies to playback on the iBook and be able to transfer them to my iPhone 4 or iPad at any time.
Is there any method for getting 480p to encode and playback well on this iBook without making it look like crap or using the old DivX avi standard? If I have to reduce all my movies for playback on the iBook, I don't want to go lower than 480p because I want the same conversions to work on my iPhone 4 as well with decent quality. It is redundant to keep making copies of each movie for each device. Anyone have any suggestions? I don't want to take my little netbook around with me because the screen is too small and there is no opticle drive.
If anyone has any ideas, please post which Handbrake profile or other that can work... or let me know if my iBook is just garbage now. Thanks!
