Question - TE25 - Should I interlace or deinterlace? No.30020
Will Hay  2002-10-29 09:17:19 ( ID:dhjxyoqacl6 )   [ Delete / Reply with quotation ]

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


Ashy  2002-10-29 13:31:35 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

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.

Question - TE25 - Converted x4 .avi's of same type - only one out of synch No.30019
Will Hay  2002-10-29 09:05:15 ( ID:dhjxyoqacl6 )   [ Delete / Reply with quotation ]

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

koka  2002-10-29 08:07:40 ( ID:8buzgb12aog )   [ Delete / Reply with quotation ]

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.

Question - TE25 - Best way to process a segmented avi ? No.30007
a.graichen  2002-10-28 22:03:07 ( ID:p4bakfomxpk )   [ Delete / Reply with quotation ]

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.


Ashy  2002-10-28 22:08:40 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

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.

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


Ashy  2002-10-29 13:40:42 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

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.

wcpaul  2002-10-30 01:53:37 ( ID:q7gr550x3gw )   [ Delete / Reply with quotation ]

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.


Ashy  2002-10-30 11:23:46 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

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)

Don Beto  2002-10-31 02:55:13 ( ID:ra54zhw1zgr )   [ Delete / Reply with quotation ]

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


Ashy  2002-10-31 10:52:07 ( ID:n3gjkhi6dvc )   [ Delete / Reply with quotation ]

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.

Question - TE25 - The optimal encoding scheme for movies No.30003
Marc  2002-10-28 19:22:41 ( ID:m8b9qxujdzn )   [ Delete / Reply with quotation ]

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


Minion  2002-10-28 19:48:32 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

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...


wcpaul  2002-10-30 01:48:15 ( ID:q7gr550x3gw )   [ Delete / Reply with quotation ]

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


Minion  2002-10-28 19:45:00 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

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....



Question - TE25 - I get noise/artifacts in encoded videos, are they avoidable? No.29996
cepye  2002-10-28 18:53:30 ( ID:cxve0zxdd6a )   [ Delete / Reply with quotation ]

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.


Minion  2002-10-28 19:43:42 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

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...?


matt  2002-10-28 21:24:42 ( ID:gzqyzz0drzc )   [ Delete / Reply with quotation ]

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.


wcpaul  2002-10-30 18:19:56 ( ID:q7gr550x3gw )   [ Delete / Reply with quotation ]

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.


Ashy  2002-10-30 19:28:48 ( ID:4adzcnohuc. )   [ Delete / Reply with quotation ]

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

Question - TE25 - Variable bit rate encoding? No.29994
cvk  2002-10-28 18:48:39 ( ID:da6ouo2f.ta )   [ Delete / Reply with quotation ]


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.

Hi folks

I can`t finish the decoding job (AVI 2 MPEG) cause the program is always hanging after a while. Sometimes it stopps after 14%, sometimes after 45%.. After hanging the whole computer has stopped...can`t move the mouse.... even the numlock-light has no reaction.... tried to change the codecs, but no reaction..please help me !!!!!!!!!

No, it is always the same.... got the same thing when I use the Windows Media Player 8....after a while playing the movie stops and the whole computer is frozen....seems to be a software problem...but I dont know....want to reinstall WMP 8 but can`t find it anywhere (execpt on the Win XP CD) but I can not uninstall the player cuz it does not appear under "Add/Remove Software" in the control panel....So seems to be the same prob by WMP and TMPGENC...Any suggestions ?


Minion  2002-10-29 08:10:05 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

You can un-install media player in XP By going to "Controll Panel" to "Add/Remove Programs" to "Add/Remove Windows conponents" ,it"s on the side of the window....Well if you are haveing this freezeing problem when doing other things besides encodeing then it could be a Conflict in your system or something....?


psychoplasma  2002-10-29 12:03:54 ( ID:.thqnqpuieg )   [ Delete / Reply with quotation ]

THX for answering my query....just encoded another AVI-File and it worked this time... I am now trying a third one to know whether it depends on the one file or not...perhaps the one file has a broken frame or something like that.. i can watch it normally (without any errors) on PC but can not encode it.... so I will try another one to know... Is it possible to re-code it from AVI (with error) to AVI (without errors) ??....Can`t still find the WMP8 uninstall option under "Add/Remove Windows Components".. :-??

By the way: What is better: CBR or VBR ? Is a CBR of 1800 enough for viewing a SVCD on DVD Playa ?

THX in advance

PP

It You are haveing this problem Quite often andf even when not encodeing, maybe you should consider a Clean Re-install on your OS and start from Scratch..I actually do this about 0nce a Month because of one problem or another and it is easier than hopeing the problem will fix it"s self and quicker that Trying to figure out what the problem is for a long time and still not fiXing it...Just a Thought...

rapsag  2002-10-28 13:43:46 ( ID:k4icn2exzqa )   [ Delete / Reply with quotation ]

I have an half-our AVI file I made from a video. The AVI file is fine. But after I encode it to MPEG1 using TMPGEnc, the sound gets farther behind as the mpEG is played. At about 20 minutes in the sound is about 7 secinds behind the video.

Any suggestions?

Thanks!
Jim


Minion  2002-10-28 19:53:53 ( ID:w8yn5mktf8w )   [ Delete / Reply with quotation ]

You say this AVI was made from a Video...Do you mean that it was Captured from a Capture card of some sort from TV or VCR??This can be caused by Dropped frames while captureing, depending on what capture program was used some don"t compensate for Dropped frames..Or if you didn"t drop frames you can still have sync problems cuz when captureing the Soun card usus it"s own clock to mesure time and so does the Capture card, and in most cases there is a Little differance between the to clocks so ove a Long capture the sound will go out...most of the good capture programs compensate for this by adjusting the Audio frequency...

Your CPU/motherboard combination may not be quick enough. I had the same problem with a Pentium III.

I got round it by setting the "Output bitstream for edit (Closed GOP)" flag on the GOP structure tab in settings. After that, synchronisation was perfect.
