Wav To AC3

[stigslim]

Right, i know what i am doin (sort of).I have followed the correct tutorial about converting Wav to AC3 using MP3 Machine with the Besweet exe.I am using this to convert to AC3 at 25 frames.But when i run it, it doesnt start transcoding like it should iy just flashes up the black screen like its gonna start then stops.Any ideas?.Any help would be great, thanx in advance.


O.K i have read the log file and the reason its not starting is this any help now?

Do you have ac3enc.dll loaded?

[julitomg]

I use ffmpegGUI for wav to ac3 conversions and works great, simple and fast.

[sanjayk]

ffmpegGUI is good to encode to 2 channel AC3

[stigslim]

right got it pretty much figured out but just one problem.After altering the framerate on the video the audio is too long after its converted to AC3, can you help me with this one please.Cheers

Now you have to provide more details.

What is the source video, what are you trying to achive and what software(s) are you using etc, etc ..

I previously had the same problem. Download the latest beta version of besweet instead of the stable version and it should work.

[stigslim]

Right, for more details.First off, the version of BeeSweet i am using is v1.5b31, is this the newest Beta?.Anyway its like this.The source video is 1323 Kbps, 23.976 fps, 640*352 (16:9), XVID = XVID Mpeg-4.And the audio is 154 Kbps, 48000 Hz, 2 channels, 0x55 = MPEG Layer-3.Now i am stripping the video and auio using Virtual Dub Mod (making the video as 25fps which is working o.k and the audio as a WAV file).Next i try to convert the audio to AC3 using Beesweet And Beelight as a GUI and yes i do change it to 25fps this works no probs and it plays.This is where the problems start.The video and the audio are different in size/time, so when i encode the video to DVD and bang em together usin TMPGenc Xpress it runs great and looks fantastic but the audio is out of sync with he video.Phew, there you go all the info i could manage without gettin a headache, can you help now?.Again thanx in advance

When using Virtualdub/Virtualdub Mod to change the fps, try creating a video file by doing the following:

1) Load up your file in virtualdub
2) Under the Audio tab, select "No Audio"
3) Under the Video tab, select "Direct Stream Copy"
4) Under the file tab, select "Save As AVI"
5) Load the resulting file back into virtualdub and change the fps to 25
6) Use this file along with your audio from Besweet for Tmpgenc

Hope this helps. Good luck.

I tried everything you told me about in the above post, but im afraid with no luck.The video came out at a shorter one hour 57 and the audio still comes out the same length as the original 2hours two mins or so.Still hacked off so any other ideas?.

[sanjayk]

I suggest you try encoding the video to DVD specs and leave the audio as it is in AC3. Then mux the video and audio together using TMPGEnc

[stigslim]

Still no luck .The audio is still out and still plays as longer in length than the video.Is there any way to shrink the audio to match the video.AAAAAAAAAArrrrggggghh this is doin my swede in.I can get the video lookin sweet, but the audio (allthough a little quiet) just don't add up.Any more halp someone must have crackes this at some point i cant be the only one?.

[stigslim]

Anybody????????.I could really do with some help here

1. Convert audio to WAV.
2. Note exact video runtime in virtualdub.
3. Open WAV in GoldWave and go to edit > Timewarp.
4. Input time as recorded in 2.
5. Save out to new WAV.
6. Convert to AC3 with ffmpeggui, belight, besweet, etc etc.
