XSVCD

[videogeorge]

Trying to gain a bit of knowledge on XSVCD. I understand that there is no standard, but I have found little details on this format. What are the advantages over SVCD? How is the viewing quality?

Essentially, I am currenyly playing with miniDVD as an convenient method to preserve & present my personal video (from cam). I'd like to maintain the picture quality achieved with miniDVD, but feel I can sacrifice a bit on the audio side due to the source. The end result I am looking for is a longer miniDVD (18 minutes is a bit short for my goals) with the same video quality. Any help would be appreciated.

It would not be that wise to change the audio bitrate of these XSCVD's which you transform into cDVD's/mini-DVD's as the most you would gain would be 1-2mins but then hearing a terrible sound. You should try seeing at what bitrate you start to notice a quality degrade in your video. I too at first captured/encoded at 10Mb/sec bitrates, but have noticed that I can go down to about 5-6Mb/sec bitrate without suffering a great deal on the picture quality which gives me an extra 5 mins. You could also try XVCD @ 4Mb/sec bitrate, but I personally find the video more 2 dimentional unlike mpeg2.

If you want to make XSVCD's to be able to play on your standalone player, you will have to check that your player will actually play them and what max. bitrate is. Most players (that play SVCD) allow up to 2.5-3Mb/sec, others will go up to 5MB/sec bitrates. So best thing to do is experiment around.

If you do change the bitrate of the audio from lets say 224kb/sec to 128kb/sec you'll gain about 15% more space, but the sound fullness (especially in music videos) is gone.
