Background music in (S)VCD photo CD background, possible, sequence, standard

andy

Hi.

I authored two photo CDs (VCD 2.0 and SVCD) using
VCDEasy.
Is it possible to include a background music track
to be played while the photo show is playing?

Thanks

so far I know this is not in VCD specifications(for example, 1000 photos with 20 background sondtracks). But you can do similar things in WinOnCD 5.0/6.0 under quot;music albumquot; for not too many photos, also must with tricks to remove the forced standard texts.

Hi HTC10825.

Is it possible to convert a sequence of mpeg stills into an mpeg file,
keeping , for example, 5 sec of permanence for each still frame?
In this case a sound track could be multiplexed to it.

I got to multiplex a sound track to one only mpeg still, but this
has few practical possibilities.

Thanks.

I think the only way to do it and remain in spec is to just make an mpg. Use the still pic as your frame and just have it repeat over and over again for the length of your audio. TMPGenc can do this all for you.  Obviously this is not ideal but its the only compliant way to do it.

The non-compliant way is to specify the audio for the item in an xml script and then author in vcdimager. This way you can have the same audio track used for any number of stills which saves you tons of space. The obvious drawback is that many (most?) dvd players won't be able to play it.

WinOnCD allows for 99 albums of 99 photos with music track for each album. I use SSMM 3.5.2 to create AVI file from my photos with different transition effects add background music. Then encode in CCE as SVCD and burn it.

SSMM is a good freeware software and you can find it here.

I've mentioned the method of WinOnCD. But it is far from ideal for practical use. WinOnCD encodes all audio in 224(256?)kbps, even though in most cases 128kbps is enough.
The advantage of music album: the still image has the resolution of 704x756. V.s. the solution with self encoded svcd: 480x576.
The disadvantage of encoding in CCE(v2.50): the maximum GOP length is 15(=5x3). Thus you cannt reduce the bitrate of mpg stream too much. If you use TMPGenc to encode, you can try very large GOP(e.g. 24x3).

@htc10825

Can u please eloberate the advantage of having large GOP and what different bitrate settings affect the quality of the slide show. For PAL (25 FPS) with 5 seconds for the slide and 1 second for transition effect. What should be the ideal setting.

for still images there are no motions btw. the frames, the the size of P- amp; B-frames are very small, but the I-frame comes with the begin of every GOP, this is the so called key frame and has the voll size even though this is a still image. So with a large GOP, 2-pass VBR(0-1150/2500), and average bitrate 100-400kbps(depending on how complex the image and if there is some transitions) you should get a usable resault. Try it manually to get the optimals and last but not least good luck!



I fond a stupid method to make a still picture with audio .
1. Use winoncd make a photo album and add a song in it;
2. make a c2d image file;
3. Use winoncd cd-emulator mount *.c2d;
4. Enter emulator cd-rom, as: H:,enter h:\segment\, fond the filesize largest file , as :Item***.dat, this file contain pictures and audio;
5. copy Item*.dat to your hard disk;
6.repeat 1-5 ,make others photo album *.dat.
6.Open vcdeasy, add those *.dat files to file list. and push quot;Goquot;, make a photo vcd image.
OK
