Maybe one of you guys testing the G1 could put up a few different options for us.
1. Maximum settings - best video and audio for the G1 (largest file size)
2. Average settings - decent video and audio for the G1 (smaller file size)
3. Minimum settings - lowest video and audio for the G1 (smallest file size)
I think this would help out the users greatly as they could decide which kind of video they would like to see / play and then encode based on this.
I would be more concerned about the AAC extension. The settings posted here result in "AAC SBR" for audio. None of the videos I tried on the G1 played audio with this extension. Need to get rid of SBR, but how? The ones that worked were ones that had no extension other than AAC.
This is what SBR is and it is apparently NOT supported in the .1 player:
About Spectral Band Replication (SBR)
SBR is a unique bandwidth extension technique which enables audio codecs to operate at significantly lower bit-rates without sacrificing sound quality. In HE-AAC, SBR is coupled with AAC to enhance its efficiency in a backward- and forward-compatible manner.
For an idea on settings:
I still need to figure out the correct AAC extension because coding as listed here creates the AAC SBR extension for audio and this has no sound in the .1 player, but....
For video, the best compromise is 384kps and check the hi quality block on the right (this acts like a double pass to get rid of blocks during fast moving scenes). It takes almost twice as long to decode but worth it for smooth video and no blockies and save space.
25fps is best option in any case, since 15 frames per second results in less smooth video.
If you do not care for space and do not mind more cpu drain, 768kps is good for video and less need for taking twice as long with the hg setting. I prefer saving space, so I would use the hq setting at 384kbs. Well, I will when I know the correct audio settings! Note: Anything above 768kbs did not display video with the G1 player.
For audio, 128kbs is perfect, but 64kps saves space and sounds "okay".
I don't have any issues with audio at all with any of the 200+ movies I've converted this past week. That is strange.
Are you playing them on the G1? The movies do have sound, but no sound on the g1 when I tested. If you are playing them on the
G1 it is good news, but I do not understand the difference there might be.
I checked again today. AAC SBR does NOT work on the .1 player with the G1. You will get video but no audio. The videos that had audio had no AAC extensions. At least the sixteen
video sample implies this. AAC (SBR for sure) equals no audio using the .1 video player.
Please let me know if your findings conflict with this.
