I have been trying to convert some avi's that are divx with mp3 audio and I have been using tmpgenc and also tried several other programs but have been getting the same result.There is either no audio or just a static hissing depending on what player I use.I tried to strip the audio out with virtual dub and have v-dub process it into lpcm then add it back to the avi and re-encode but it didn't work.Why is it that there is no audio with these avi with mp3 audio conversions.I haven't had any problems up until now when I try these with mp3.G-spot says I have all the codecs when I run the avi with it.Any help on this would be greatly appreciated since I am trying to convert and burn one of my favorite movies "chopper". thank you, honyak45
Are you sure that wile has MP3 audio, or VirtualDub , in File___Information displays 'unknown'? I say this because this is a typical 'AVI with AC3 sound' issue. Try to do this test: 1) open that AVI with VirtualDubMod (useful modifcation); 2) do stream___stream list. What does it show? If, as I think, it shows AC3 simply click the 'Demux' button. Then, if you're making a DVD, author the DVD using that AC3 (delay=0) as sound. If you're making a (S)VCD it's a little more complicated, because you have to convert 48 kHz 'audio.AC3' into a 44.1 kHz MP2 file (HeadAC3he, FFMPEG GUI), than you have to multiplex video (M1V or M2V) and sound (MP2) toghether to create a MPG (MPEG-1 for VCD, MPEG-2 for SVCD)...
O.K. when i ran the avi through g-spot it said it had mpeg 1 layer 3 audio so i'm pretty sure that means it has mp3 audio right?And I downloaded v-dub-mod and when I tried to install it it said cannot install corona.dll not found what should I do?
TMPGEnc has issues with VBR mp3 audio. It will accept it as a valid audio source (won't happen with AC3 unless you have an AC3 decoder, in which case no problem), but then not convert it. My advice would be to frameserve with AVISynth. Didn't think VDubMod had an installer. Just a zip. http://prdownloads.sourceforge.net/virtualdubmod/VirtualDubMod_1_5_10_2_All_inclusive.zip?download The "All_inclusive" is the importand part. Sounds like you downloaded some kind of update package.
yep i think it was an update because i found the all inclusive and it opened no problem.So i did the stream and it does have the vbr mp3 audio so I demuxed it now what do i do with the audio file.Also if i try to enter the avi with a seperate audio source the avi always fills both the video source and audio source slots.just to be clear i'm using tmpgenc,and it doesn't matter which one they all give the same problem.I have tried this avi in a couple of other converters too and got no audio.I just tried downloading avisynth and took a look at it and it is way over my head.I am new to this so I dont have any idea what frameserving is and i definitely cant do any programming or scripting.At least not unless someone sat down with me and went over it step by step.So i'm thinking I need to convert that audio file I got from the v-dub-mod demux to something acceptable by tmpgenc,then use that as the audio source.but how can I add the video only to the video source slot without it loading the mp3 it had to begin with?
Try FitCD to create the script. Instead of demuxing in VDub, you can set the audio to full processing and save out a pcm wav. You can use that as the audio and it should be ok. AVISynth is faster though. The audio gets decoded on the fly and it can resize faster than TMPGEnc.
Well I finally figured it out.I demuxed with v-dubmod then took the mp3 audio file and converted it to mp2 with winxmedia cd and mp3 converter then used tmpgenc 3.0 express and loaded the new mp2 file as the audio source and the original avi for video and it converted to an mpg. with the audio present this time!Thank god that nightmare is over.I can't believe how simple the solution was to fix it but I have only been doing this stuff for about 2-3 months.I don't know much but I am steadily learning.I just ordered a case of 200 taiyo yuden 8x dvd-r discs,the good silver thermal lacquer coated ones and 100 jewel cases.Supermediastore has some great prices on media and they pretty much only sell quality stuff.They even have the new 50gb blue-ray discs and I guess are working on 100gb and even 200gb discs!Thats a lot of space for a single disc.And their archival life expectancy is more than 50 years.They show no degradation after being overwritten over 10,000 times.My package of 200 ty discs and 100 jewel cases only came to 98.00$ which is way cheaper than buying the stuff at say fry's or someplace else.So over the next couple of months I will most likely be posting a lot more and hopefully not with just problems.Thanks to anyone who has tried to help me. honyak45
Just a suggestion: get used in having ELEMENTARY streams, that is: NOT a MPG, but a MPEG video (MPV, that is a M2V if a it is MPEG-2 for a DVD) and an audio (DVD accepts either: Mpeg audio [MP2], Dolby Digital audio [AC3], Uncompresssed audio [WAV]). The 'authoring' application I use (IFOEdit and DVD Lab) do not want mpegs, but elementary streams (DVD Lab de-multiplexes the mpg input, if required). More: the audio type should be decided BEFORE encoding. Unless you use an AVI which already has AC3 5+1 (384 kbps), the AVI files have MP3 streams (usually 128 kbps, often time less , raraly with a highe bitrate). Threfore, unless your AC3 already has an AC3 streams (and VirtualDubMod tells you if it is 384 kbps or even 448 kbps), you save 100% the sound quality if youi encode tnto a MP2 22k kbps or an AC3 192 kbps. When you encode to MPEG-2, the encoders ask you which bitrate it must apply. It can go from 2500 kbps to 8500 kbps. Which is the 'ideal' bitrate? It is calculated by a bitrate Calculator (I use the freeware DVTool 0.53). You insert the movie's length (e.g. 123'), the audio type (e.g. MP2 224 kbps or AC3 192 kbps or the bitate of your AVI's audio, if it had AC3 sound) and the software outputs you the 'ideal' bitrate. For instance: a movie 122' long can be encoded to mpeg-2 with these 'ideal bitrates': a) 4575 kbps if the DVD will have AC3 sound 448 kbps; b) 4639 kbps if the DVD will have AC3 sound 384 kbps; c) 4799 kbps if the DVD will have MP2 sound 224 kbps; d) 4831 kbps if the DVD will have AC3 sound 192 kbps (the software has 'MP3 optimal', but it is for an AC3 sound, which you can prepare with FFMPEG GUI). 99% of the times you'll use c) or d) (no way to make a 5+1 stream from an 1+1 MP3 stream). Therefore: 1) determine the audio type; 2) calculate the 'ideal' bitrate to fit a 4489 MB DVD by M2V+audio; 3) encode the M2V; 4) author the DVD (M2V + audio = DVD). All clear?
