video size VCD

I have trouble when export the photo to MPEG-1 using Magix movie edit.
The result of MPEG-1 has bad resolution of image than original one.
I'm trying use video size 720x480, 720x576 and 768x576 with 4000 Kbits/sec (bit rate), 29.97 (frame rate)

Hi there.

:

Does that mean you want an MPG still-frame :?:
If so, then you'd better be using TMPGEnc and an adequate quantize matrix:

HTH.

Well, the VCD spec is:
http://www.videohelp.com/vcd

PAL Video: (Shouldn't you use that in Singapore?)
1150 kbit/sec MPEG-1
352 x 288 pixels
25 frames/second

or NTSC/NTSC Film
Video: 1150 kbit/sec MPEG-1
352 x 240 pixels
29,97 frames/second
23,976 frames/second NTSC Film

So you see it's much lower resolution and bitrate.

Are you trying to make a VCD with
1. a series of user-advanceable MPEG stills?
or
2. a video track pre-mixed-down from a timed/transitioning slideshow?

#1 allows encoding MPEG1 stills format (704 x 480/576), wheras #2 only allows MPEG1 video format (352 x 240/288). Use VCDEasy's stills encoder tool for the stills, use TMPGEnc for the video.

Also, if you're actually trying to make a compliant VCD, your bitrate is WAY too high!
