I'm using an avi file and I'm trying to change it into a MPEG-2 NTSC cbr 4000kbps and in the middle of encoding I get an STREAM WRITTING ERROR what causes this error and how can I fix it. Hey and how do you fix the purple screen you get when changing an avi into an MPEG-2

If you are getting a Purple screen then that can be caused by 2 things either you have the "Angel Potion codec" installed on your Machine which you should delete or you just need to raise the "Direct Show" file reader in the "Vfapi Plugins"...I think Stream writeing errors happen when you run out of Disk space..But I"m not sure if this is your problem so check to see if you have enough disk space.

No it not that I got lots of space at least 30 gb but I still get it. How do I check direct show vfapi plug in?

Well if you don"t have the "Angel potion Codec" then raise the "Direct show file reader" by going to "Options" to "enviromental Settings" to "Vfapi Plugins" and raise the "direct show" to "2"...

I the tmpeg program? How about the stream error?

And what happens if we don't have the plugin. I mean I downloaded it but I don't think I installed it properly. How do you install it.

hey, i'm having a sound problem with making a magnolia mpg. i used dvd2avi to create a wav file that plays fine. however, when i try to create an mpg with tmpgenc, the video plays fine but there is no audio. i've tried doing it 3 times but i can't get it to work. everything has worked great on other movies though. any thoughts?

Is the wav actually loading into the audio field?

Try raising the priority of the wav reader in the VFAPI plugins.

And if all elce fails use something elce to encode the audio to mp2...

Ashy Ive been having trouble encoding episodes of a programme called dragonball Z! what happens is if i leave the direct show(enviromental settings) at -1 it does not recognise the avi files! But if i change the direct show to anything else the sound starts to jump! Playing for a second then being silent for a second! This continues through all the episodes i have done. I got told to use virtual dub for the audio and change it into a wav file. But sadly this does not help! Is there any way of sorting this as I never used to have this problem. Thanks In advance!!!!

What format are the AVI's in and what format are you encoding to?

When you extract the audio to a wav file does the wav file play ok in media player?
Have you tried raising the priority of the wav reader also?

If all else fails just encode the the movie without audio then use either dbpoweramp or MPEGDJencoder (much, much faster) to encode the audio to MPEG2 and multiplex the 2 files together.

I'm in a position where I can capture home movies through my Matrox capture card, run through TMPGEnc and author menu's with Ulead Movie Factory.
I tend to use the settings already set for me but wonder if I can achieve better quality by playing around.
I don't understand interlacing and deinterlacing, could someone tell me when and when not to use this?
Thanks,
Will

If possible capture to your card without using interlacing this is called progressive frames. It will save you many problems later.

If you intend to watch the output on TV then use interlacing. If it's for monitor only don't use interlacing (progressive frames)
Having said that most DVD players are capable of playing progressive sources anyway, but DVD specs require MPEG2 sources to be interlaced.
MPEG1 is usually progressive.

I downloaded four divx .avi files and converted them all to mpeg using TMPGEnc. Three are perfect except one where sound doesn't match the video - it is out of synch.
The file plays fine as an .avi it only goes out of synch after I use TMPGEnc.
Anyone know what causes this and how to fix it?
Thanks,
Will

I use WinXP, Premiere 6.0, a videoserver and Tmpgenc. At the end of the movie (30 minutes) audio and video are not synchronized. The difference is about 1 second. What's wrong? I don't have this problem when I use Windows2k.

Ive been told how 2use virtual dub! to extract my mp3 as a wav file! But the sound still comes out the same when i convert it! is there nything else i could try?

The same as what? What problem are you having.

ASHY

Hmm, I see you are double posting about the same problem. Please refrain from this practice. It is unecessary and will get your post ignored and/or deleted.

Hi,
I captured a tv-movie into multiple .avi segments because of the 4GB barrier in FAT32. Whats the best(fastest) way to process these files to a VCD.

For the moment I create a batch encoding list and merge the result at the end. Is there a better (automated) way to do this?

Thank you. Andreas.

Yes. Which program did you use to create the segments?
If you used Virtualdub then just load the first segment and frameserve to TMPG. Vdub will load the rest automatically.

If not load the first segment into Virtualdub and use the append function to add each subsequent segment then frameserve to TMPG. The segments will encoded as one complete file.

For info how to set up the frameserver consult the Virtualdub help files.

ASHY

I would like to frame serve AVI segments (PicVideo MJPEG mostly)as Ashy suggests, but VirtualDub won't let me append some (same frame sizes but either slightly different frame rates or other unknown factors - some segments made in MSP6). Is there another way of doing this? Also Andreas, how exactly do you do this batch encoding list?
Thanks, Bob

If you have differing framerates then it is no wonder you are experiencing problems.

Even if you use TMPG to encode the files individually to the same framerate you will still encounter problems as TMPG does not do correct framerate conversion.

The files will join no prob, but will have jerky playback in some areas.

I would advise you to correct the framerates first in each file to make them identical with each other. This will desync the audio though, so you will have to use cooledit or soundforge to expand or shrink the audio to re-sync it.

ASHY

Use an Avisynth script with AlignedSplice (++):

AVISource("file1.avi") ++ AVISource("file2.avi")

This fixes problems with sound going out of sync.

I always keep a template file for this handy.

But will most likely still give you conversion problems in TMPG.
If you are well versed with AVIsynth then you could use the 'ConvertFPS' command to convert all the files to the correct framerate. AVIsynth can do correct framerate conversion and is far better than using TMPG to do it.

Use this command in your script - CONVERTFPS(29.97)

ASHY

I'm not sure if my question is for VirtualDub, MSP6, or TMPGEnc.
My problem is that I captured alot of segments in VirtualDub with MJPEG and a Matroz Rainbow Runner, and for some reason the rate was slightly off (29.9706); Also the VirtualDub properties show PICVideo MJPEG instead of the Matrox MJPEG.
Anyway, I want to edit (add transition, etc.) in MSP6. I can't seem to re-compress to MJPEG from MSP6 anyway, because the resultant file is so huge. How can I use TMPGEnc for final rendering? From experimenting with smaller files, I notice TMPGEnc rendering is noticably better than the one in MSP6.
Sorry to be so lenthy. What is AVISynth? Can you point me?
Thanks,
Bob

For AVIsynth go to http://www.videotools.net

There is also a new release on the site which will allow you to frameserve the files from Ulead Media Studio Pro v6 to TMPG which may help you.

Hi,

I'll try to find the optimal encoding scheme for movies. I tried
several like 2 Pass VBR, Constant Quality, etc. It is not clear
what the best scheme is for movies. Can somebody give me a hint?

Thanks,

Marc

The Best way is what ever looks best to you...And every file has different properties which make so you might get better results with different settings from file to file...Generally the "CQ" method ballances file size and Quality to give the best output but that is a matter of opinion...

If there are only sporadic high motion sequences in the movie you can push the average bitrate for 2-pass VBR pretty low and still get good quality.

You just have to experiment with much longer clips to get the setting right.

A shortcut is to run CQ qual=100 for a high motion sample and check the average bitrate with a bitrate tool. Knock 2000 or 3000 Kbs off that number and set it as the 2pass VBR average.

Queuing some trials to run overnight is worth the effort. Every 1000 Kbs savings over a 1 hour movie reduces the file by almost 500MB.

Thank you all. I've found a great tool, DVD2SVCD who can do
the job well, extremely simple and gives great quality. A
real recommendation to all AVI to MPG coders!!!!

hi there! Ive been having problems with the sound on my avi files while converting! I got told to use vitual dub! But cant seem 2 work it! Can some1 tell me how to run it please! Thanks

To extraxt the avi file to a WAV File with Virtual Dub you just load the file into V-Dub then go to "File" to "Save as WAV" and that is it....

I usually encode MPEG-2 video in PAL DVD format, with the Constant Quality method, quality set at 100 (maximum), and the min/max bitrate left at 2000/8000 as it comes. I also use the slowest motion search, and 10 bits of precision (I want quality above everything else).

So, I generally get good quality, but at some points the enconded video shows some artifacts on screen (little but noticeable squares). They don't appear too often but they appear nonetheless, and I would like to make a completely clean video in order to archive it into a DVD. In addition, if I encode the same video twice with the same conditions, the artifacts can perfectly appear one time but not the other.

I don't know if it matters, but I use AviSynth in order to frameserve the video to TMPGEnc from an Adobe Premiere project.

Thanks for your help.

If you can try loading the file directly into tmpgenc and encodeing it without useing AVISynth or Premier and see it the problem get"s better...?

You may want to try using CBR (Constant BitRate) instead of Constant Quality. The file size will increase compared to the Constant Quality mode, but you will always have the same bitrate (8000kbps or whatever you set as the bitrate). This MAY eliminate the blocks you are seeing.

If you are making a reference archive of "difficult" original material, 8Mbs may not be enough. Also, if the source is Hi8, or similar, consider using 4:2:2P@ML.

Run the BitrateViewer tool to see what your Q levels are in good versus bad areas of the footage. Adjust max Mbs to keep Q low and use 2pass if you need to conserve file size.

DVD compliant video might require more experimentation, but you should be able get a virtually lossless result even at 8Mbs.

I don't think 4:2:2P@ML is a valid level for DVD authoring.

I encoded an mpeg file with the 2 pass variable bit rate with 2000000/4000000/8000000 min/avg/max settings respectively. The resulting output file is almost exactly the same size as one encoded at a CBR of 8000000. I tried the same encoding with the Dazzle MovieStar software, and the variable bitrate encode came out to roughly half the size of the CBR 8000000 encode.

I would have expected the TMPGenc VBR output to be noticably smaller than the CBR setting. Is there a reason why?

Thanks.

This shouldn"t happen so I wouldn"t know why...
