VOBs and .mpv were complete but .mpg was cut off

[terrypeng]

Sorry if this problem has been posted. I've searched the forums for weeks but still can't figure it out. Thanks in advance for any help.

I am using dvd2svcd with default settings but the SVCD created from .bin/.cue was cut off the last 2+ mins. I used PowerDVD to play Encoded_Video_TMPGEnc_NTSC.mpv and it was complete (50:01). All VOB files were complete. However, bbMPEG_Muxed_File00.mpg was cut off (only 47:49). I tried DVD Rip with Internal routines and vStrip but both have the same result.

Very puzzling. Unlikely to be a ripping problem as the encoded video file works. You don't mention the audio. Does Encoded_audio.mp2 play all the way through in media player? If not post your BeSweet log.

As for muxing, if both video and audio are OK I can't see why this has failed. bbMPEG at least usually stops with an error message!

Try multiplexing manually in TMPGEnc. Open MPEG Tools from the file menu, choose multiplex tab and select MPEG2 Super VideoCD (VBR) as your output. Browse for you mpv and mp2 files for video and audio source respectively and save your output as bbMPEG_Muxed_File00.mpg over the faulty one.

Try playing the file. If TMPGEnc fails to mux to the end post back giving any error message it gives. If it plays fully do a crash recovery in DVD2SVCD from the SVCD authoring stage.

If that doesn't work get VCDEasy and author the image files yourself. It is no longer freeware but the last freeware version is still available ( click me (http://www.pc-magazin.de/datatip/common/dtt/download.php?areaid=66&fileid=2245) ). If you find you use it a lot, upgrade to the latest version and invest $15 in the author by registering it.

That should sort it in this instance but if it happens frequently on various different DVD's, try a full deinstall and reinstall then post back here.

PS Welcome to the forum - nice first post. Did everything right.

Hi terrypeng,

TMPGENc in CQ mode isn't enough accurate. Many times you have an oversized or undersized video. Not sure what happens in the case of a single CD, but probably D2S is cutting the mpg in order to do not create a CD image too big.

To check this:
- Check your video size. It must be below
"Wanted: 671780906 (656036kb)"
- If higher, try changing bbMPEGCDSize parameter in dvd2svcd project file.d2s to 810 or 820, and then recover from mux & cutting. You will get a Image too big, but may be with overburn you still can use it.

CQ mode is the best quality/encoding_time in TMPGENc, but the predicted size is not accurate enough. To avoid future problems of oversizing, you can change "CQ value factor" in Encoder tab to a value less than 1. The general result will be CD not completely filled, but the probability of oversizing will be lower.

Many thanks to Nick and Jsoto's comments. I've solved the problem and convert at least 3 DVDs with this cut-off issue earlier. Here is what I have done in the past two days.

1. Both Encoded_audio_1.mp2 and Encoded_Video_TMPGEnc_NTSC.mpv were complete (50:01). But bbMPEG_Muxed_File00.mpg was cut off (only 47:49).
2. Tried to deinstall, reboot, and reinstall DVD2SVCD: same cut-off problem.
3. Tried to install DVD2SVCD on another machine: same cut-off problem.
4. I read jsoto's comment. So I changed Encoder(TMPGEnc)'s Rate Control Mode from Constant Quality(CR) to Automatic variable bitrate (CQ VR). The rest of settings are default. Then it works. I am not familiar with TMPGEnc. Can someone elaborates the Rate Control Modes (CBR, VBR, CQ, CQ VR) and when I should use which mode?

Thanks

[Nick]

Ok. You have a fixed number of bits available on your target discs and MPEG compression needs bits to record movement. There are two ways to determine bitrate distribution - Size based encoding and quality based encoding.

Size based is where the encoder divides the disc size in bits by the movie length in seconds to see how many bits per second it has to play with. This value is called Average Bitrate. There are two subtypes of size based encodes -

CBR (Constant bitrate) where the calculated average is used to encode the movie. So action scenes are of low quality - the extra movement needs more bits to encode well. Quieter scenes that don't need many bits have extra bits wasted upon them as CBR makes no provision for this. It is however, very quick. Use it for test encodes and perhaps for putting short films on DVDR as the average bitrate value is then very high anyway.

VBR (Variable bitrate) does the above but then goes back over the movie, looking for quiet scenes to steal bits from and then reallocating these bits to the bit-hungry action scenes. This is where Min and Max bitrates come in. Therefore the quality is better but it takes ages!

Quality based is where test clips are encoded from random samples of the movie. From these, a Quality factor can be calculated - say a 2% sample of the movie was encoded and filled 4% of your target discs, if you encoded the sample at half that quality 2% of the movie would have filled 2% of your discs. So encode the whole movie at half that quality it should exactly fill the discs...
The advantages of this method are that every scene is encoded to a preset quality so the quality of the encode is top notch. It is much quicker than 2 pass VBR. Its downside is that if the sample is not representative of the movie as a whole, the sums don't add up and you may get oversize or undersized output files.

So you either live with the long VBR encodes, or you live with the occasional file size error with CQ - it's down to you.

This is quite a simplification but should clarify the principles of what you're doing. I hope it helps.

[jsoto]

A very clear summary (as usual) from Nick

Nothing to add, except my personal rules when I used TMPGENc. IMHO, CQ mode in TMPGENc gives better quality than 2 pass VBR, so I lived with the "problem" of oversized files. To save it, I recoded (using D2S recover function) the video using a fixed Q just a little lower than the one calculated by D2S (around 10% of the times).

Other choice is to manually recode the audio to a lower bitrate, but recovering from mux in D2S with this "trick" does not work fine (it still works with the original audio bitrate), so you have to mux and author manually.
