Please help improve my framerates on vcds in my dvd player

[darkside]

Hi everyone, i am very new here so please help:

using the conversion guides on this site i have managed to convert avi and divx files to vcd, first using virtual dub for saving wav file and frame rate info. tmpgenc is used as the encoder and splitting the files in two, the only options i check are : loading the correct template to match framerate using virtdub info, under settings i select motion capture to "high quality"
and video setting "centre keep aspect ratio". when previewed on these settings the video runs really smooth with no hint of frame loss or jerkiness.
after i burn the encoded file using nero (latest) and the proper resolution pal etc , play it using my standalone dvd. their is visible frameloss which is very very frustrating as encodes can take up to 10 hours start to end.
just to point the source files are all dvd rips of a very high standard, im sure this loss happens during encoding...please please help

If you followed the procedures you describe correctly, then I dont see anyway that frames would be lost during encoding and your problems msut be elsewhere. 1st thing I would suggest is downloading an example VCD clip, burn to CD and watch carefully. If this has the same problems then the issue is either your burning process or your player. In this case try reducing the speed at which you burn your CD's or try a different brand of CD as some players are very fussy about the media you use. You could also try playing the VCD's in a friends DVD player to see if the same problems occur.
If none of these work, then post your question again listing what you have tried so you dont get the same answers again.

Hope this helps

cheers for the reply.......firstly the cdrs im using prop havent won awards for quality but seem to get the job done..secondly i only burn at 4x to get a good deep burn (compensate for tacky cd-rs} and my friends scowl at my quality as its apparent on their players too!
a new question about bitrates and altering their settings...would that make a differenc to frame rate? plus the "rate control setting " on tmpgenc, i leave all on default....could this make a difference?

ps could you give me a link to a quality demo vcd :)

Well, VCD format is not great quality at the best of times. Most people compare it to VHS and maybe the VCD conversions are that quality bit IMHO they are generally poorer. If you change the bitrate from the template you immediatley become non standard, so you have to try these things to see if your player can handle them. As for frame rate, you should ensure the frame rate in TmpGenc is the same as the divx movie you are converting from. Use the template that matches the frame rate for best results.

23.97fps = NTSC film
25 fps = PAL
29.97 fps = NTSC

If you end up with a format your player cant handle by doing this (i.e. the divx is Pal and you can only play NTSC) you may have to do a format conversion to get decent results. There is a guide on this site and plenty of discussion in the forums on doing this.

converting divx .avi files to VCD/SVCD is never a good idea in terms of quality...in essence, the divx already loss alotta quality when it was compressed to a smaller file, expanding it to a bigger VCD/SVCD file wouldn't do you any good in terms of quality and i've even heard, it makes the quality worse than the divx

that is very true however, using someones tips on this forum i have unlocked the 30 day limit on creating svcds with tmpg, these are vastly superior to vcds ...i am now a very content encoder :D

When I convert from DIVX to VCD/SVCD first I save the .WAV file in VirtualDub. Then code in TMPGEnc which produces the a 1.7gb file. if I split that in half I can not fit the CD1 or CD2 on a CD-R because the file size is too large. Does any one have any ideas I how to make the file sizes smaller.

well what i do is instead of encoding the complete file then splitting it up i use the wizard on tmpg for svcds. when u get to source range it tells u how many minutes your selecting when you select an end of frame point, the next screen tells you how much disc space u will use with the current setting...if u have spare space click back and extend your end frame until your happy with filling all space. i do this and since i want a quality image i keep the bitrate as high as poss, usually meaning a 3 disc movie.
what u could do is split the file in half and on the next screen it shows that the file is greater than the disc space. u then reduce the bitrate which reduces file size until it fits on disc...be sure to choose the right disc in the menu 74 min or 80 min...this should fit on to 2 discs at the expense of quality
