Can somebody, if possible somebody who has access to the source code, give me the /exact/ definition of what the "Output as basic YCbCR, not CCIR601" option does in both of its states?
Especially, does it scale luma/chroma values, and if yes, in which of its states? Or does it only clip values when unchecked?
This affects the range of values accepted for luminance and chrominance signals. YCrCb is raw samples, taking the range 0-255. In TV systems CCIR601 is normally used, which restricts the allowed range to 16-235 for luminance and 16-240 for chrominance signals. If you are mastering for TV (e.g. VCD, SVCD, DVD) then do not tick this option.
1.) Not ticking it throws away Y values below 16 or above 235, but leaves the others alone, and similarily for chroma?
2.) Not ticking it scales down the luma input values so that 0 becomes 16, 1 becomes ca. 17, etc. and 255 becomes 235, 254 becomes ca. 234 etc.
3.) Ticking it will make TMPGenc leave all the values alone.
4.) Ticking it will make TMPGenc scale up the values, so that 16 and below become 0, 17 becomes ca. 1, 235 and above becomes 255, 234 becomes ca. 254 etc.
It depends on your input. If you are using DVD2AVI you have the option to output to TV or PC scale. TV will be 16-235 and PC 0-255.
If you are encoding for TV then the scale should always be 16-235 otherwise, and you can test this yourself, the picture becomes slightly darker, blacks become dark grey and whites aren't quite white, colours also seem to be become slightly deeper.
Your TV expects 16 to be the lowest value for black, use the 0-255 scale and 16 won't be quite black when outputted to you TV, but as I have said dark grey the same is true for white.
If you don't tick then all values will be correct for TV.
I suppose the choice may partly be down to personal preference, but if you want my advice and the correct scale for TV then you should be using CCIR601 for all your encodes.
ASHY is nearly right. But DVD2AVI is a little Buggy.
You have two Options to Choice:
PC- or TV-Scale
YUV 4:2:2 or RGB
The different Combination of those two gives completely different Outputs.
RGB + TV-Scale gives a darker Picture. So it depent's on the Settings, if CCIR or YCbCr is right.
If you are not shure, how to handle this, use always CCIR. Better to dark then to bright (and Off Standard).
I need to convert some quicktime MOV files to mpeg format. I have found some references on forums stating that there is a TMPGenc plugin for Quicktime that allows TMPGenc to convert MOV files to mpeg.
Can you please advise
1. if this is correct?
2. The name of the plugin?
3. where to get the plugin?
You can get the Quicktime Mov Plugin in the download section of "www.vcdhelp.com"...you can easily find it elsewere if you look on a Search engine.........

You Can"t register the "DEMO" version..You have to download the "Plus" version..You can get it By Clicking the Banner you see at the bottom of this Page..Once you install it you will find were to Enter the Number...
This error Is Cause By Bad Or Corrupted AVI files..Usually with Files downloaded Off the net..There is no real Fix for this accept you can start encodeing were it crashed useing the Source Range and Join the 2 parts together with the Merge & Cut....Or you might try Frame serveing the file to tmpgenc ..
I have been trying to encode an mpg file to mpg1. WHen I tried it the first time I got a message saying that TMPGEnc needed to download QuickTime Authoring. Every time it tried it said it was corrupted, try again.
It's always corrupted is there anywhere I can manually download it from and what is the file called.
If I try to encode the file without the download TMPGEnc either stops responding or produces a file with no sound.
This is wierd..You do not need Quicktime to to encode Mpeg to Mpeg But you do need it to encode "Quicktime MOV" to mpeg...So Maybe the file you are trying to encode isn"t a Mpeg file but a Mov file???? since This problem is so wierd I don"t really have a Solution for you....
I think it's something to do with the sound encoding. TMPGEnc says it isn't a valid audio stream if I try to demux it.
I have the Quicktime plugin and can convert .MOV files (though without sound, hmmm) so I assume the authoring is a different plugin or whatever.
Strange thing is Winamp 3 will play the original but the sound turns into a loud hiss after the first couple of seconds but MS Media Player plays it OK.
Well you Can extract the audio to a WAV file, if it is a Mov file then you can use "Sound Forge" to do this , then you can encode the Wav file as the Audio source...
After converting a DVD to SVCD (using the SVCD Movie Template) and then burning it to a CD-R, the movie play well if it wasn't for occasional frame skips. It's if the movie is fast fowarding by a second or two from time to time.
Can anyone help me solve this problem ???
Thank You.
Do mean that the Video seems to Speed up or slow down Just for a second once in a While??I believe that this is Caused By sudden Bitrate spikes in the encoded Video wich Makes the Drive in the DVD Player have to suddenly speed up But the drive can"t speed up fast enough..This is a Dual Problem, a Problem with Tmpgenc Haveing Bitrate spikes and a Problem with the Drive in your DVD Player Not being fast enough to compensate for the Bitrate spikes...I don"t really know of a Solution for this accept Maybe useing a Lower Bitrate or a Encoder that doesn"t spike the Bitrate, or get a DVD Player with a Faster Drive in it....
After selecting the file to convert to MPEG1 and the Wizard opens, I have ot way of changing the settings such as FPS, SIF, or Kbit/sec, when clicking on settings all of these options are grayed out and won't let me change them. Any help?
To Change the settings you either have to load the "Unlock.MCF" template from the "Extra" Folder or Click on the name of the setting it"s self then go to "Unlock",Remember you Have to encode the mpeg file to the same Frame rate as the AVI file, and you have to keep the Resolution to the standard for the format you are encodeing to, meaning if the AVI file has a Frame rate of 23.9fps you have to encode it to 23.9fps and if you are makeing a VCD then the resolution has to be 352+240 for NTSC VCD..you can"t encode for example a 25fps file to say 29.9fps ECT....
was wondering if some1 could help me? ive found recently when im encoding 20 minute avi files it is comeing up that it will take 5hours. Once it is encoded i open the file and it is coming up that the files are 60mins lkong instead of 20 mins long! im also finding that ther eis no sound either! Does anyone know how to fix this?
chears
Well it seems that there could be something wrong with the AVI file..The audio issue is easy ,The audio in the AVI file is Not being decoded so it needs to Be extracted to a WAV file and that used as the audio source...Try useing the "Source Range" to set the begining and end points of the AVI file...and what is in the extra 40 minutes of the mpeg file???
I am having trouble playing VCD's in a stand alone DVD player. Back in October, I made my first collection of VCD's (Band of Brother's - all 10) and they worked perfectly in my current stand alone DVD and even in some stand alone DVD players owned by some friends in the dorms when i went back to college. This morning, since i'm on xmas break, i decided to crack out the VCD stuff again. The only problem is that this other DVD player that my family bought won't display my VCD's. It is a Sony - almost identical to the other DVD player i first used to test my VCDs. According to vcdhelp.com, only 2 Sony DVD's don't support VCDs and this one is not one of those 2. In fact, it says right on the front of it: "Supports DVD/CD/Video CD". It won't play any of the ones i made today or the ones i made a while ago. It just says NO DISC and skips to the next disc in the 5 disc changer. I'm a bit stuck on what to do. It supports yet says no disc. Is there something i need to burn at the beginning of the cd's to tell the dvd player to play?
This is Odviously a DVD Player issue and not a Tmpgenc issue..If the VCD"s you made a While ago Played on your other player then the VCD"s are fine and the DVD Player has issues..My First DVD Player would Play DVD"s But not play any of the VCD"s I put in it and it said it supported them So I returned it and exchanged it for the exact same model But this one worked Just fine so Maybe the VCD Function on the DVD Player is Busted....
Don't be fooled by that clap trap on the front of Sony players. Most Sony players do not play homemade VCD's. Yes some will play VCD's as stated, but this means the pre-recorded variety only.
Most Sony players such as the Sony Davs3000 and similar will not play VCD from a CDR, but you may be lucky as these players will accept CDRW VCD's.
CDRW are nearer to the the reflected light wavelength of DVD's than CDR therefore as long as your player can read the disk it should play your VCD.
I have used TMPGEnc for a while now and everything was working fine. Recently when I try to encode, about 12 minutes into the encoding my computer resets. If my computer doesnt reset, the screen says "Out of source range", on what looks like a dos screen. I have no idea what it might be... if anyone can help please email: ecw666@cs.com . Thanks
