It seems to me that tmpenc doesn't allow 4:2:2 to be created conforming to the 422Profile spec.
The spec. clearly allows for up to 720x608 and bitrates up to 50Mbps - but Tmpgenc 2.5 plus complains that the bitrate is too high if it is set above 15Mbps in this profile - and this is incorrect.
A properly formatted SD NTSC Broadcast Mpeg2 should be 720x512 422P@ML (32 line blanking interval + 486 active image area), and allow for bitrates up to 50Mbps.
Also, to properly incorporate a 720x486 active area onto a 720x512 full-field Mpeg2, Tmpgenc needs to allow the user to position the original 720x486 (or 720x480) into the correct position in the final output - right now you can only center the image or squeeze it to fill the whole fram - but what is needed is a way to position it so that the first line of a 720x486 original file can be placed at line 26 of the 720x512 result - (or for 720x480 it needs to start at line 32)
I see no way in Tmpgenc v2.5 plus to do this. Is it possible with tmpgenc at all?

Here is the spec. for 422profile:-

4:2:2Profile@MainLevel
Abbreviation: 422P@ML
The goal of 4:2:2Profile@MainLevel is to be suitable for application in the TV production environment.
So the performance, in terms of video coded quality, is expected to be better than MainProfile@MainLevel. Furthermore the 4:2:2Profile should provide good performance also when several coding and decoding processes are necessary, but the number of generations should be kept limited, as the MPEG compression techniques are lossy.
The main removed limitation on the profile side is the chroma_format, 4:2:2, that gives the name to the profile, is possible and it should allow chroma key effects for the decoded images. Besides also the Intra DC precision may be improved (till 11 bits).
On the level side the most important increased parameter value is Maximum Bit Rate, 50 Mbps, that allows a good picture quality even with only Intra_pictures, so that applications that used Motion-JPEG compression (non-standard) can now use an MPEG-2 standard profile.

Vertical Vector Range (frame pictures)-128:+127.5
Note:
Compared to MainProfile@MainLevel the number of lines/frame has been increased in order to include some lines from the Vertical Blanking Interval.
The maximum value of Luminance Sample Rate is lower than the simple product of the Sample Density values because the frame size 720x608 is used for 25Hz countries, while in 30Hz countries the format is
720x512.

Hello,

When a DivX video has been authored,
I understand that it needs a DivX Ultra certifed player
to be able to see/experience the menus.

But, will such an authored video play at all on a non-Ultra player?

or, will it just play like a regular video,
but obviously without menus?

Thanks for answering my beginner question :-)

Yes it will just play the video itself.

I just installed 2.5 plus and the silly thing loaded one time. Now, every time I try to call the program, the .exe file shows up as loaded in task manager process but does not show up on screen or in the applications window of task manager. When I shut windows down it comes up asking me to close 2.5 plus, which I cannot even see is running.... this is very frustrating. Any help will be appreciated. BTW, I have uninstalled it, cleaned the registry, reinstalled and same problem. After it asks for registration, it disappears.

Hello,
I would like to transcode MPEG-1 from MPEG-2 and simultaneously insert a visible image watermark on the MPEG-1. Does any of your software support such a feature?
Thank you

I guess this is still not supported but they may hear your voice some day.

good luck

I'm using TX4, but the TX4 forum seems to be gone.
I have an mp4 video, H.264 (3GPP).
When I open it with TX4, it's reading the video size wrong, and when I try to encode, it takes forever, just to encode a few frames. If I left it running, my great grandkids, would probably still be waiting for it to complete.
I tried disabling the Quicktime reader, but then nothing happens.

Any ideas... or is this just a bug?
I sometimes have the same problem with mkv files.

Thanks for any help!!

I'm having trouble with the authored disc playback. the MPEGS are all fine when you play them on a PC and the authoring process works and a disc is produced, but on playback there is digital breakup of the image just near the end of each chapter, This has not always happenned always but is happenning all the time recently. the whole image pixelates right at the end. Has anyone experienced this and does upgrading to version 3 solved this for anyone?

I am unable to encode avi to DVD with your product and still maintain lip sync. please advise .

I've just started using DVD Author 3 I have created a project with page 1 welcome screen, page 2, 6 chapters for 6 clips.
1. How do you get only one clip to play
2. How to at the end of the clip to return to page 2 (it currently goes back to page 1).
Thanks

I just paid $89.95 for the retail version of DVD Author 3. First I had to BUY the software on line and then a page opened with the serial #. Then I had to copy & paste that into their webpage so I could download the software. Then I installed it and they said to restart my computer, which I did. But, then when I opened the program, they again asked for the serial #, but once I restarted my computer, that page of course dissappeared. I checked my email, but they never sent the serial # there. Now I'm out $89.95 and they are impossible to reach. What do I do?

SERIAL FOR TMPG ENCODE DVD 3

Hi,

My wife's PC died and I'll be giving her my current PC with DVD Author 2.0 on it. I want to uninstall it off this PC and install it on my new PC. Is this OK or will I have any issues/problems with licensing?

Thanks!

I am trying to brighten up a rather dark avi file that I want to burn to a dvd, make a movie of it.

Instead of just brightening it in VirtualDub and then putting the result into Nero I've been told I'll get better results by frameserving it to tmpg and burning the result with imgburn.

Fair enough.

I set up Virtualdub load the file, set the filter for brightness and start the frameserver.

It creates a vdr file and that's what I'm supposed to point tmpg to. But it doesn't recognise the type of file.

So I find I should install a plugin and I downloaded and tried to follow the instructions for an avs plugin: VFAPI plugin for TMPGEnc/AviUtl
Here they are:
How to install:
1. put m2v.vfp and m2vconf.exe into the same folder.
2. execute m2vconf.exe
3. select options
4. push OK button

Well that didn't seem to do any good so I put them in same directory as tmpgplus but it still didn't do any good.

Can anyone help me out, show me where I've gone wrong?

regards,

ab :)

Can TMPGEnc DVD Author 3 with DivX® Authoring run with VISTA ULTIMATE 64 BIT ???
Thanks for your help !

I always thought that Scrubs is a great TV show, not only for the great acting and the funny scripts, but also for showing what working in a hospital is really like. Every doctor will say that "life is not like ER", and scrubs didn't take the whole heroic position and the action-drama scenes, that frankly, is much less common in hospitals than an old man with diarrhea, reflux, colitis or other not so very "photographic" diseases.
