I've tried VCD coding a couple movies now that used the XviD codec to create the original avi's. For some reason, when the coding stops, I get a perfect video sequence, but no audio.
Any suggestions?

A Lot of the Audio in Xvid and DivX files these days have AC3 or VBR-Mp3 audio, and Tmpgenc doesn"t support these Audio Formats..You need to Extract the audio to Wav format then use the wav as the audio source....

I have some MPGEG 2 SVCD files, which are 7-800 MB in size. I need to resize them to 650 to fit CD-R size. But some of these files consequently interrupts after only around 7 minutes of the film is converted. I've solved it by re-converting them to from MPEG to MPEG but that takes a hell of a time and sometimes it even freezes before it's finished. Can somebody give me a clue to what the problem or better the solution is?

Better solution?
Just get your self some 80min cdr's. You can fit 800mb of MPEG data on one CDR and are just as cheap as 74min CDR which can fit up to 740mb of MPEG data

If you overburn you can fit about 820mb on an 80min CDR and 756mb on a 74min CDR.

and again if needed:I just made a little .mpg by putting an animation i made as the video and a song from my band as the audio.

The animation goes for about 21 seconds and i want to make it loop, because the song keps going. At the moment I made it , it plays once then stopps, while the song contiunues.

When i made the animation in microsoft gif animator, i saved it as repeating forever, but this makes no difference..

could you please email me with help?
Thanks in advance :)

Because Mpegs don't support this. You'll just have to load your MPEG into the MERG&CUT feature to join multiple copies of your MPEG together.
No need to make more copies just keep loading the same one until the total running time of the MPEGs matches your audio.
You can check this by clicking the edit button.

I've searched and read through this board and I still can't see a clear answer to this problem. A split AVI file plays fine with the audio in sync to the very end of the clip. When I use TMPGEnc to encode it for VCD, the video starts to lag the audio about three quarters the way through and at 6 hours per try, I'm getting very upset. The AVI was split using Virtual Dub and the first half of the split runs fine as a finished VCD. It's onlly the second half that has a problem. I've even exported the audio as a wave file and the recombined it with TMPGEnc, still with no luck. Then I tried editing the wave file and added a few seconds into it where I lose sync then recombined using TMPGEnc again. Still goes out of sync at the same place. Why, if the origional AVI is in sync all the way through and the split portions check out okay, am I loosing it when it's converted with TMPGEnc? I don't know what else to try.

What you should do Is Just encode the Video, and after encodeing the Video find out the Exact length of the Mpeg Video File, then check the Length of the Wav audio file and see if they are Exactly the Same Length, if there is a Sync Problem the Audio will be a Little Longer or Shorter than the Video, sou you would need a Program Like "Cool Edit" or "Sound Forge" to Stretch or Shrink the Audio to the Same Length as the Video, once the audio is the correct length just Encode the Audio to Mp2 and Mux it with the Video..That Is how I fix all My sync Problems....

Hi all,

I have a question here.

I have a file in RealMedia VBR format. which means a .rmvb format. I would like to convert this file to a format that allows me to burn into a vcd format.
Is there anyway to achieve this?

Please enlighten..

Thanks in Advance..

You will have to Convert the RM files to AVI first if you want to use Tmpgenc to encode them to Mpeg, you can convert the RM Files to AVI with a Program called Tinra or EO_Video, Tinra is Freeware and can be found on Any Search engine, EO-Video isn"t Freeware but it has a Lot more features Like it will even convert from RM to Mpeg1/2 but the Quality isn"t as good as Tmpgenc...

Thanks for the advice, but the video format I have is in .rmvb format which is different from a .rm format.

I tried to rename the .rmvb to .rm but it does not work.

Further advice??

Thanks in advance again

Hello everybody. I work for an Italian digital-video involved company.
We have a little problem. we have a big amount of AVI to store, and we don't know what kind of compression to choose, we'd like to keep the best quality and the lesser space....

i thought the MPEG-2 could be a good solution, at 1:1 ratio, highest quality..

Or .. should i try something else as DIVX?

Thanks for your help.

Well Mpeg-4/DivX will give you as good of Quality and Smaller File sizes than Mpeg-2, But there will allways be some Quality loss anytime you are compressing Video Data but if the Quality of your Source Files is Good the Quality loss should not be Noticeable...

The key to archival decision is what "lesser space" means. MPEG2 can do excellent compression at 8Mbs, "very" lossless compression at 12-15 Mbs and extremely lossless (4:2:2 using MP@HL) at about 18Mbs. This consumes less space than DV, at much better quality. Broadcasters routinely use 15Mbs 4:2:2P@ML to digitize their older archives.

I have used MPEG4 (Divx 5.0.3) but can never get a compressed result which is indistiguishable from the original for EVERY frame, even at 8Mbs. As soon as you get away from an I frame, the quality goes down.

Remember, the underlying compression of both techniques is the pretty much the same. MPEG4 just ads effects to trick the eye into overlooking compression artifacts for very long GOPs when viewed at full frame rate (in tiny computer windows).

If the AVI originally came from DV (4:1:1), it must be archived with 4:2:2 color sampling to prevent half the color samples from being lost during conversion.

By the way, here is my compression test:

Choose know frames from original and compressed videos which have NO motion. Extract out to BMP files (DVD2AVI, vfapiconv, VirtualDub copy frame to clipboard, paste in Paint, save).

Toggle rapidly between BMPs in a picture viewer. The toggle should not be noticeable. Carefully check many pattern types in several frames.

Compare highly zoomed views of an area which has subtle textures.

If resolution is lost in frames with no motion, reject the compression method.

After passing that test, motion can be evaluated but this just boils down to a well known bitrate vs quality judgement.

I've already picked system video and audio but when the encoding is done the video is blank and all you can hear isthe audio so could I please get some help please the movies are AVI from Kazaa if that helps any
thanks for taking your time to help me out!

First Make sure you have the Right Codecs installed, if you do then go to "Options" to "Enviromental Settings" to "vfapi Plugins" and Raise the "Direct Show" to "2"..and if you do not see an image in the Screen while you are encodeing then there will not be an Image in the File....

Why is it better to use the non-standard quantize matrix for non-intrablocks, i mean, doesn't it have effect on the quality ?

Thanks

I need to split an existing 1.2 gig mpg video and am a little new to video editing but lately 1 gig + videos have been showing up and I just don;t have a dvdrw yat... What would be the appropriate settings to split a 1.2 gig mpg then make 2 svcd's? Thanks for the help

What????????

Just split it into 2 equal parts and choose the correct stream type for the output.

I'm surprised you even needed to ask such a question unless I don't understand the it.

I am also surprised someone would ask a Question like this, a Very small amount of Math and common sence would solve this dilema..

I've never used TMPGenc before... i tried it a few times this morning like the the help lage @ vcdhelp.com displays and for reasons i'm unaware of the split first half of the video regardless of where I set the divide markers is consistantly 17mb and not a byte larger...??? Any ideas?

Try this.

I have several avi's that tmpgenc seems to have a problem with. This happens whenever I use the wizard. As soon as I choose the input video file it says 'Judging Field Order' , then after only 2% I get 'floating point error'. I tried these same files without the wizard and I don't have too much of a problem but do still occasionally get the 'floating point error' only it is usually somewhere during the encoding process.
Any ideas?

Thanks in advance.

Floating Point errors are usually caused by Errors in your Source File, this is common with Downloaded files cuz they usually are riddled with errors that can cause the encoder to Error out or crash..There isn"t much you can do about it in Tmpgenc, you can try scanning for errors and makeing a copy of the file with Virtual Dub this can sometimes fix the errors in the file....

I captured some NTSC TV programs on mini DV tape. I plan to convert these tapes to VCD. The VCDs will be played on a NTSC TV. The original footage was telecined.

I used TMPGENC wizard: First I selected "VCD 29.97 fps" and then checked the "Inverse Telecine" box. The resulting file looks choppy when viewed on a TV.

1. Did I make the proper TMPGENC selections? Should I have selected "VCD 23.97 fps"?

2. Will the file look better on a TV if I do not choose "Inverse Telecine"?

How do you know the original footage was telecined if it was TV footage?

In any case you cannot use IVTC on this footage and even if you did you cannot just leave the frame rate at 23.976 fps after IVTC.
You would still need to re-telecine this material to make it NTSC compliant.

You can only IVTC original progressive material which has been Telecined. You have lost the original progressive frames by capturing to 29.97 interlaced frames.
You need to encode this footage at 29.97 fps.

Ashy - you asked "How do you know the original footage was telecined if it was TV footage?"

Answer: When I view the captured footage frame-by-frame, I see a repeating pattern of three progressive frames followed by two frames with interlace artifacts.

I will encode the captured file at 29.97 fps.

Here's another question: When I encode at 23.976 fps and burn a VCD, how does my DVD player output 29.97 fps? Would I get the same jerky motion if I used SVCD?

You cannot output a 23.976 VCD at 29.97. You would need to encode it to 29.97.
Only MPEG2 supports adding 3:2 pulldown to 23.976 sources.

>Answer: When I view the captured footage frame-by-frame, I see a repeating pattern of three progressive frames followed by two frames with interlace artifacts.

If this is indeed the case then you may be able to use IVTC on this material.
After IVTC does this material play ok on the PC?

If so encode then encode this material to MPEG2 using pulldown.

Ashy asked: "After IVTC does this material play ok on the PC?"

Answer: This plays very smoothe on a pc. It's only jerky on a TV.
-----------------------

TmpgEnc has an option for 23.976 fps VCD. What does this option do that is different from 29.97 fps VCD?

>Answer: This plays very smooth on a pc. It's only jerky on a TV.

If this is the case then it seems the footage has been properly IVTC'd

The 23.976 VCD setting you refer to is for Film material, but most hardware players will not play this material correctly moreover most players will convert the frame rate to 29.97 causing frame rate conversion artifacts such as jerky playback.
In most cases for playback on a hardware player the VCD has to be 29.97.

Only when encoding to MPEG2 can the framerate be set to 23.976, but 3:2 pulldown must also be used to make the MPEG play at the required 29.97 fps.
