After you said encoded video actually has less quality than the source i took a bad quality video i used the best settings i could and the filters to try and make it look as good as possible. When i was done i watched both videos and noticed that it actually improved the quality! There was a noticable less amount of block noise. And also is there a type of kazaa like program that is specifically made for trading high quality media?
Using Filters is just that you filter out things hence lossing data your picture may seem better but your source file gave up data. Some filters blur the picture to make the picture take on a less blocky apperance others do different things but in the end the picture is no better than the origanal it is all a matter of perspective. A simple but true statement is "You can never get better than the Source" or (Sh*t in = Sh*t out)and this aplies here.
I agree. It is just your perception which is fooling you.
Creating a better picture than the original impossible, but altering cetain characteristics may give this effect. It all depends on what you mean by better.
There are different things that people will percieve as a better picture.
For example some people may prefer a less blocky picture than the original which can only be acheived by some sort of blurring to hide the effect, as blocks cannot be removed, but this will have the effect of a slightly less sharp image.
Another person may percieve a better quality image that has more colour saturation and a higher sharpness than the original therfore making the image look clearer, but this will have the effect of accentuating noise in the image.
As I say it's all down to the viewers perception and what they percieve as a better picture. What one person thinks is better may not be what the next person thinks.
I have a bunch of AVI's that are just under 4 Gigs in size (about 25 minutes in length). Verified to be correct.
When I load them up into TMPGEnc and try to encode them. For some reason they are interpreted as almost an hours long. It thinks video is in the first 25 minutes, and most of the audio is in the last 25 minutes.
More accurately the result is the audio is in the first few minutes of the file, then stops, video is fine. After the 25 minutes of video are over, then there's a long break, then at the end of the 1 hour, the audio is there, with no video.
When I go to select the "source range" of frames, I can only select (as I would expect) the 25 minutes of video.
The AVI's play fine other wise, so it seems like I have some sort of VFAPI plug-in priorities set incorrectly?
Frameserve these files from Virtualdub to TMPG. If you still have problems you can use AVIsynth for this task. AVIsynth will allow you to use any size file.
Would there be a way for tmpgenc to automatically incorporate FitCDs VBR settings for max and min settings although it may be over 2530. Also when using the vbr, what is the recommended min to prevent any type of jittering effects or constant speed ups during play back and the appearance of little green macroblocks.
This difficult to answer because it all depends on your machine.
Many tests have determined that 1800kb/s is the bare minimum you can get away with if you wish to prevent Macroblocks in regular scenes.
As for jittering and speed ups this has more to do with your Max bitrate. If you set it to high your machine will fail to decode the data correctly thus causing these effects.
This is caused by your player not being able to spin the disk fast enough to supply the high bitrate data which means your player cannot read the data from the cd correctly and feed it to the decoder which will cause data loss hence skipping, jittering, de-sync, speed ups e.t.c.
You are seriously mistaken. TMPGenc is well worth every penny and it works superbly. I use it to Make DVD's into MPG1,MPG2,DIVX,AVI,VCD and SVCD's Most people that have problems here are those who either don¡Çt know how to use the program, do not have codecs installed or have computer issues. Dear "The lost man" please don¡Çt give up on one of the best Encoders ever or will truly have "lost out" TMPGenc is by far one of the cheapest and high quality Encoders out there. The only one I would even say might be better would cost thousands of dollars. So $48 is an awesome deal. If you have problems which it appears you do then ask questions that¡Çs why this BBS is here and read past answered posts you will see the truth and also that their are a few experts in dealing with problems here named Minion and Ashy.~NewtronX
All I can say is 'a bad workman always blames his tools'
TMPG is renowned in most if not all Video encoding,editing,production forums as being the single best encoder there is and unbeatable for the price.
It seems you have obviously had some bad experiences with TMPG. This is probably due to your lack of knowledge in using the program.
Encoding with a program such as TMPG takes time to reach perfection. If you don't have the willingness and patience to learn to use it then you are bound to get less than desirable results.
TMPG is not meant as an automatic solution for producing perfect MPEGs without some effort on the part of the user and this is your problem.
Learn to use the program, if you are having problems use this forum for answers. I assure you, once you get the some basic knowledge in using the program and understand how to create good quality MPEGs then you will be more than satisfied with the cost you paid for such a great unmatched piece of software which most of us would be lost without.
I captured (DC10+, Windows XP) an old VHS tape with a datarate 4500Kbits/Sec. I handled the AVI within Studio 7 and rendered the file to a new AVI file with the same datarate (MJPEG). Since this is one to one (MJPEG) it is done rather quick.
This AVI looks fine when I watched it using a mediaplayer.
When I make use of TMPGenc (CQ 85, Max 2520, min 1800) and render the AVI to MPG then the MPG stutters at some movements.
I made hundreds of MPG using the above way and never had any problems. The only thing what is changed is that i capture the VHS tape now at 4500Kbits/sec under XP instead of 3500 Kbits/Sec under W98se. TMPGenc encoded the AVI´s always fine. ´Till now.
Can this be the reason?
What datarate can you advise when you capture an AVI file. As high as possible?
Sounds like It Could be a Field order problem..If you are useing the Plus Version and you load your files into the Wizard it analizes the file for the correct Field order and adjusts it accordingly, but if you just load the file in normally then the field order is not adjusted...And make sure that you are encodeing to the same frame rate that you are captureing to.but becides these things that is all I can think of that could be causeing the stuttering problem...
Convert a MP@ML Mpeg2 file to HP@HL(4:2:2,CBR 7.5M) Mpeg2 by Tmpgenc 2.57plus.
WMP, PowerDVD,WinDVD can't open/playback the file.
what kind software can play it, thx!
Just as a silly question. Why did you convert MP@ML Mpeg2 file to HP@HL(4:2:2,CBR 7.5M). What was the point?
I doubt you acheived a quality increase as the original was already MP@ML.
To get any sort of benefit from such an encoding you would have to start with very high quality raw footage.
ok so I have to admit I'm a bit of a newbie at this, but I've tried everything so far before i resort to hassling u all about it.
I'm having major trouble getting my audio synced up.
Ripped blade using smart ripper, flasked into avi so i have a divx, and for the last 4 days i've been trying to make svcds using tmpgenc.
I've ripped out the audio using virtual dub, encoded the movie and sound together, and to be honest the whole mpeg file plays back fine through media player, but as soon as i transfer to cds using nero or vcdeasy i get the same problem.... the audio is 0.3 seconds begind the movie (not the case for the mpeg).....
anyone know a quick fix for this rather than encode everything again and deliberately offset the audio????
i've had a look at using the mpeg tools for demultiplexing the audio from the video, but once i've done this i can't use these files in virtual dub as it doesn't like them..
I don"t know who told you that was how you make a SVCD out of a DVD Rip but that isn"t how you do it, unless you need the DivX file for another purpose, cuZ encodeing it to DivX will make you loose a lot of Quality instead of encodeing right from the DVD"s Vob files...The Best way is to use DVD2AVI to make a D2V project file and a Wav file and then encode that to SVCD...but since you probably don"t have the VOB files anymore explaining it won"t help...Is the audio the same amount out of sybc the whole way through the file??If it is then you can use the "Multiplexor" in Mpeg2vcr to mux the audio and video together cuz it has a feature that will let you off set the audio to sync up with the video.You Cant load SVCD files into Virtual Dub anyways cuz it doesn"t support Mpeg2 files and why would wou want to anyways??...In the future if you want to make a Proper SVCD from a DVD do it the proper way and you will have lots less problems...
hey thanks for getting back to me..
yeah I know that the method i've been through to get to svcd is weird but i did want the divx file u see, and to be honest most of the svcds i will be making will be from a divx source so i need to sort out the method i've been using.
the mpegtovcr tool sounds just the job so thanks a bunch i'll go get it now. yeah the audio is offset 0.3 secs all the way through the movie... only by the time it gets to my dvd player though as cds though, not through a pc player... weird!!
thanks for your words minion, and as promised i'm yer best mate =)
Hang on a minute here, if you go offsetting nthe audio deliberately so your DVD will play it in sync even though the original MPEG is in sync then I'm afraid you may find that when you play the movie in another player, you will experience audio desync again.
Does the movie you have created have audio desync even when you play the burned disk on your PC?
If the answer is yes then you may get away with the adding the audio skew. If not then addindg skew is not the answer.
If the original is in perfect sync then so should be the burned movie on both your PC and your DVD player.
Some DVD players are incompatible with certain burning softwares and earlier versions of Nero are known to cause this problem.
If you are using a new version of Nero then I would suggest using another piece of burning software.
Try doing a search on google.com for Instant cd-dvd which has been known to correct the problem.
Another important tip is to never burn above 4x as in most cases you will experience problems.
One other question I will leave you with. Have you used the MPEGtools to split your movie? If you have ensure you chose 'MPEG2 Super VCD(VBR)' as the stream type or you WILL experience problems when burning.
thanks for your suggestions.. you could indeed be right, however I have used nero for burning the mpegs with its own system, and now used vcdEasy which burned the image it created, so I find it a little weird that there should still be an audio problem even after just burning a direct image that vcdeasy has created !!
I'll try the playing the movie back on my pc.. t0p idea :)
however I'm now 3 steps back of where i started.. Every single mpeg that tmpenc creates for me comes back as succeeded from the log, however when trying to open the file in any player, or even with mpeg tools I get informed that the mpeg is in an unknown format, and tmpgenc reports a stream reading error.
the file sizes seem correct, just can't do anything with them.
mpegcorrector and mpegtovcr are both unable to correct the files headers either..
sheeesh.. 3 weeks after i started to do all this I still haven't got a single svcd to show for my efforts !!!
Any ideas??
I'm using tmpgenc with
tooLame
Lame
also directshow priority on 2
I'm assuming we are still referring to SVCD. Your problem of being unable to play the file back could probably be to the fact that you do not have an MPEG2 capable player installed. Media player will NOT play back MPEG2 files if you do not have a compatible MPEG2 codec installed and generally won't play back burned SVCD's at all.
Download WinDVD and try playing your MPEG2 files and SVCD's with that.
The audio doesn"t convert because the audio is not supported in Tmpgenc..You have to extract the audio to a Wav file with Virtual Dub and use that as your audio file....
Then you must not have made the avi file your self??Cuz who ever made it off set the audio at the begining of the file in an attempt to Sync it up..So The problem isn"t with Tmpgenc it is with the avi file, you probably downloaded it off Kazaa or something??Most Kazaa files aren"t very reliable and don"t encode very Well because of these audio problems or Frame rate problems or a dozzen other problems..I have been useing Tmpgenc for a Long time now and it allways works perfectly for me and allways has because I make all the avi files that I encode or I encode DVD"s that I Rip myself...
I'm trying to save a file as AVI, and under "video>setting>compression I only have Cinepack and H.263, although I installed divx 5.0.2 and bunch of other codecs.
Funny thing, my VirtualDub can encode using,say, Divx engine, but TMPGEnc can't!
Any help will be greatly appreciated!
I used dvd2svcd to rip the movie and encode it.The ripping part was oke, then TMPGEnc couldn`t download the file.
I tried to open TMPGEnc download the files manualy ,the video file downloaded, but the audio didn`t, even tough it was the right file the message said:
File"C:program files......................AviSynth_Script_file.avs" can not open, or unsupported
What do you mean TMPG wouldn't download the file?
I'm assuming you mean TMPG wouldn't open the file.
Have you actually installed AVisynth before trying to use TMPG to open the script.
You may have an error in your script. A quick check to see whether the script is ok or not is to simply open it with media player. The file should play if it's ok. If it doesn't then there is something wrong with the script or you don't have AVIsynth installed correctly.
If it does play in mediaplayer then you may need to disable the Directshow filter in TMPG under the VFAPI plugins to allow TMPG to read the file.
