Why is TMPGEnc telling me this

[90blackcrx]

Back to basics...

1. What's the length of the footage to be encoded? (Don't add anything).

2. What audio rate will you be using?

3. What filesize (from your calculations) are you expecting?

4. What filesize is TMPGEnc telling you it'll produce?

1. 1 hour and 32 mins and 50 secs

2. 192 of course

3. The file size the calculator is giving me is 4232 mb with the video bitrate 6373

4. With out using the wizard I can I find the expected size of the file ? I used the wizard even though I did not know what audio to select ( I have a different version of tmpgenc ) so anyways the file came out to be
4532.99mb which is in fact bigger then a dvd-r can hold, so how come the bitrate calculator is telling me to set the video bitrate to 6373 even though its not gonna fit on a dvd-r ?

( I edited this in after reading a little while, how come 4532.99 is to big for a size of a file, my dvd-r that I'm reading have 4.7gb of space. So wouldn't 4532.99mb fit ? I still put the file and the right bitrate into tmpge and its still over )

Also wouldn't this be a better way to use the calculatr, type in the audio bitrate size, then mess with the calculated bitrate until you get the file size under the size that will fit on a dvd-r ?


As I kind of stated above I'm using a different version of tmpgenc, I think its tmpgenc plus, anyways which audio should I choose at the beganning of the wizard, I guess it don't matter since I don't use the wizard but I was just cuiours.

Ok read up above my last reply in case you have not, I think I finally found the reason why the file is coming out to long

The bitrate calculator option for dvd size, the closet and default option is
4.37gb or 4480 mb.

Now the max file size for tmpgenc is 4199.00mb, why are they different is beyond me, maybe there is a reason someone can explain to me.

So my solution is, type in a custom dvd size in the calculator, the custom size being 4199.00 mb ( the max file size in tmpgenc ) and this way it will give me the correct video bitrate. I just tried doing the math, so does a normal dvd-r hold 4812.8mb ?

But what is really the max size of a normal 4.7 gb dvd-r, how many mb can that be ? This way I just put that in for the custom settin in the calculator. Does this make any sense ?

93 minutes in CCE would be 6100 mbits/sec. In TMPGenc I would use around 5700-5800. TMPGenc always increases the bitrate slightly more than you set. The difference between 5800 and 6100 is nothing you will notice.

I'll be honest with you, the cce and the mbits/sec lost me totally.

I can varify this though, yesterday I did encode the movie in tmpgnc and I used 6200 video bitrate, yes it was over the limit but I figured hell I would just shrink it using dvd shrink. But its not to big when I put it in tmpge author, its actually 4150gb , so I guess what I said above made sense. Anyone else care to comment on my explanation up above.

How do I get the audio file in tmpge author ? I tried converting the audio to an mp2 file and an ac3 file but its not working. Tmgen author says its an illegal file. Also the ac3 file that it creates, ffmpeggui has no size its zero, whats going on ?

*Illegal audio format.

Illegal audio format.
For a standard DVD you can only use the following audio formats:

Dolby Digital (AC-3), MPEG-1 Audio Layer-2, or Linear PCM.



For a standard DVD, you cannot use other than the above mentioned audio formats.
For example: MPEG-1 Audio Layer-3(.mp3), WindowsMediaAudio(.wma), RealAudio(.ra), etc.

Please use the audio source after it has been converted into either Dolby Digital (AC-3), MPEG-1 Audio Layer-2, or Linear PCM or capture it in the correct format.

Thats what its telling me, even though I tried using the ac3 file.

Skynet107's post reminded me - TMPGEnc is believed to (sometimes? / all the time?) produce files slightly larger than what is calculated by the (any) bitrate calculator. The calculator is correct - TMPGEnc can go over by a bit. I'd say this is happening in your case.

I edited this in after reading a little while, how come 4532.99 is to big for a size of a file, my dvd-r that I'm reading have 4.7gb of space. So wouldn't 4532.99mb fit ?

It's easier for me to quote jimmalenko to answer this:

"The 4.7GB is a marketing gimmick and is based on the fact that the general public understand the base 10 numbering system, and most wouldn't have a clue about the base 2 numbering system, which is of course computer-speak (1 KB = 1024 Bytes, etc etc).

A DVD holds 4,700,000,000 bytes

4,700,000,000 / 1024 = 4589843.75 KB (KiloBytes)

4589843.75 / 1024= 4482.269 MB (MegaBytes)

4482.269 / 1024 = 4.377 GB (GigaBytes)

So a "4.7 GB"is actually a "4.377 GB" disc in true computer-speak."

This is based on:
1Kb = 1024 bytes
1Mb = 1024Kb
1Gb = 1024Mb

Whereas the 4.7Gb is based on multiples of whole 1000's, not 1024s.

Now the max file size for tmpgenc is 4199.00mb, why are they different is beyond me, maybe there is a reason someone can explain to me.

Not sure where you're getting this from - I've not seen it. Can you expand...? When you say TMPGEnc, do you mean the encoder or the authoring tool?

I can varify this though, yesterday I did encode the movie in tmpgnc and I used 6200 video bitrate, yes it was over the limit but I figured hell I would just shrink it using dvd shrink. But its not to big when I put it in tmpge author, its actually 4150gb , so I guess what I said above made sense. Anyone else care to comment on my explanation up above.

As above, I'm not sure what this limit is you're referring to. But, if you've found a process that works for you and doesn't seem convoluted then stick with it until your knowledge is greater and you can refine it.

How do I get the audio file in tmpge author ?

nice quote

@90blackcrx:
I just punched your numbers into Videohelp.com's Bitrate Calculator and you can in fact use a video bitrate of 6373kbps to fit exactly. Normally I round down to the nearest 100 to allow for the simplest of chapter selection menus, so I'd use 6300 in this case.

TMPGEnc's wizard does its calculations assuming that you want to cap the size to 4200MB. This is just so that it has a bit of room to move if it can't quite hit the target. The easiest way around this is not to use the wizard I must say that I've never encountered a case where TMPGEnc has more than negligably overshot the size that it should encode to. I've always found that it's been literally within a few MB's every time. Use TMPGEnc just to create your M2V file

If your AVI has AC3, load the AVI into Virtualdubmod, then go to streams > stream list, click on your audio stream and click the demux button. Then later on when you get to TMPGEnc DVD AUthor, specify the M2V TMPGEnc created for you, and this AC3 file.

Ha ha, it's only fair to mention my sources...

Also, thanks for stepping in with the explanation of TMPGEnc's 4199Mb limit - I never knew that. And the AC3 extraction too - something else I've learnt.

Hopefully, 90blackcrx should now be able to get to an authored DVD.

The limit that tmpgenc was giving me, it says the file was to big to be put on a dvd-r, even though it fits with room when I added it to the author program. I just hope the sound does not take up a lot of space.

The file size might be small enough according to bitrate calculator but if I put that bitrate in tmpgenc it was saying the file was way to big for a dvd-r. I also thought that ffmpeggui would be able to handle converting it but I guess not.

Also I just used that guide for virtual dub but I'm still getting this error when I try loading the sound into tmpge author. I could listen to the ac3 file so I know it worked but author keeps tellling me its illegal, why ???

I've never used it, but AC3fix GUI (I'm assuming this comes with AC3 fix) might help sort a corrupted / damaged AC3 file.

Also, you mention VirtualDub - Did you mean to type VirtualDubMod? Coz that's what you should be using - they are different...

Yeah I ment mod. I'll try the other thing and get right back to you.

[90blackcrx]

I put it in ac3fix, renamed the file and clicked process, nothing really happen besides where it says process it says In ok, out ok. So what else, this is really starting to drive me nuts. I gotta run so I'll check this thread tonight, if there is anything that it could be please post it.

[daamon]

Sorry - I'm out of ideas and experience on Divx AC3...

I extract WAV from DV AVIs and use ffmpeggui to encode to AC3 and have never had any trouble so never needed to use stuff like VirtualDubMod and AC3fix GUI.

[90blackcrx]

Dam, well it looks like its a no go unless anyone else can think of anything else ?

Also, now I'm just talking about the bitrate calculator, what size file should be the max I should be looking for when I am using the calculator ? Just so I know, this way I can adjust the video bitrate accordingly because tmpgenc plus and tempgenc author both give different size files on what they think is the max.

[daamon]

Don't worry about filesizes with the calculator - put in your footage length of time, and the audio bitrate and it'll give you the maximum bitrate that can be used for your desired disc / ouput type (DVD5, SVCD etc.)

Take the bitrate that it gives and use a few 100 lower - this won't noticably affect the quality, but will allow you a safety margin for TMPGEnc overrun and also room for menus etc. during authoring.

FYI - last time I tried ac3fix gui, same thing happened. You might try using ac3fix from the command line. At least there, I saw it process the file, and the renamed file was created.

So should I only listen to what the calculator says, even if the calculator says it will fit on a disc but tmpgenc is telling me it won't ?

YES

As I explained, TMPGEnc (The encoder) gets it wrong by using 4200MB as the disc capacity.

Use whatever the bitrate calculator tells you and subtract 100 and you can't go wrong.

Ok thank you
