I had been using tmpgen for a few years and everything was fine. Then suddenly, when using tmpgendvd, I got the message "file must have a header". I emailed tmpgen and about a week later I got an answer. "tmpgen is not resposible for add ins". Lots of help, huh! Does anyone know what add in I need and and where to find it? thanks, jparx
You are Probably talking about the "Sequence Header before every GOP" error message... To get rid of this error you have to have the "Output interval of Sequence Header" set to "1" in the "GOP Structure" settings in Tmpgenc when encodeing your File to Mpeg-2 for DVD.... Cheers
Thanks, I'll try it. I have been converting to mpeg-1 for dvd files and in the past it has worked well. jparx
Mpeg-1 is only DVD Compliant when useing the SIF/CIF DVD Resolution (325x240 NTSC or 352x288 Pal) but all other DVD Resolutions Must use Mpeg-2, You can also use Mpeg-2 for 352x240/288 resolution and you Might also get better quality useing mpeg-2.... cheers
I finally had time to try your suggestion, it worked! I have never done anything with GOP because I don't understand it. Why didn't tmpgenc support give me that solution? Makes me wonder about their support system but I guess it doesn'e matter now. I have read in this forum that tmpgenc does not do a good job with mpeg-2 so I did mpeg-1 with audio at 48 khz. It worked OK. Are mpeg-2 files (352 X 240) much larger than mpeg-1? Thank you for all your help, it is appreciated. jparx
I don't want to add anything on the previously replies, since everything seems to be working, now. Good work, Minion. MPEG-2 is VBR: you choose min-average-max bitrate, usually min=1150 kbps and max = 2500 kbps, so you choose the average = the final size. It's the encoder, the one which decides how to allocate the bitrate and, to do this, it does multi-pass encoding. MPEG-1, instead, is plain 1150 kbps CBR. How much bigger, then, is MPEG-2 than MPEG-1? It depends. If you choosed average = 2000 kbps , the video part gets bigger by 1150/2000, the audio part remains constant (MP2 is usually kept at 224 kbps CBR). Therefore: MPEG-1 bitrate = 1150 + 224; MPEG-2 bitrate = ave + 224. Programs like FitCD detrmine the right ave to choose to make the SVCD movie to fit 2 or 3 CDs (Usually 2 CD-R are enough for < 100' movies, but this depends on the speed of the movie scenes - a faster motion requires a higher bitrate). Remember that SVCD specifications require max = 2500 kbps; DVD specifications allow up to 9000 (or 8500?) kbps.
I will give it a try later on this week. I have a new DVD to backup. I'll let you know what happens when I dol. I really appreciate your help on this. jparx
Now when I try to open a .dv2 file made with DVD2AVI in tempgenc, I get "Can't open file or usupported." It does this with .ave files also. I used unlock and checked all the settings and they look OK. It will only open .mpg files. I don't know what happened but just when I thought I would be able to use it again! jparx
Well if you get an Unsupported File Message From D2V files then it is usually Because of one of 2 reasons... The First reason would be that you don"t have the "DVD2AVI.vfp" Plugin enabled in the Tmpgenc "Vfapi Plugins"..To solve this problem you have to go into your VFAPI Plugin settings and Enable the DVD2AVI.vfp Plugin and if there isn"t one listed you have to then Copy the "DVD2AVI.vfp" file from the DVD2AVI Directory into the Tmpgenc install directory and then the DVD2AVI.vfp Plugin should show up in the VFAPI Plugins.... The Other Reason is because you either Moved or Deleted or renamed the Source VOB/Mpeg-2 Files or the D2V File...To solve this Problem you simply have to Make a New D2V File.... Cheers
The plug ins are all there. The source file was not moved. The DVD2AVI plug in priority is set to 0. I tried to set it to a higher priority but couldn't. I can open mpeg files made with a different application. ????? thnks, jparx
