Hi all, help please
How can I calculate the bitrate when you compress to divx?

For example, I have an mkv, the video bitrate is 9000 kbs, nominal bitrate 9500, how can I know that when the bitrate should compress to divx?
thank you very much

HOLA a todos, ayuda por favor,
¿como puedo calcular el bitrate cuando comprimo a divx ?

por ejemplo, tengo un mkv, el video tiene bitrate 9.000 kbs, bitrate nominal 9.500, ¿como puedo saber que bitrate debe tener cuando la comprimo a divx?
muchas gracias

I accidently downloaed TMPFEnc 2.5 Plus, installed, and then the unit expired. I uninstalled and tried to install the free version. However, I keep getting and invalid install, please install again. Any advise on uninstalling the original version? TIA

Try re-downloading the free version installer; maybe it was corrupted somehow.

I bought TMPGEnc MPEG Editor 3 earlier today. I captured a TV show using a PC capture card. MPEG2 video is PAL Progressive, I would like the output file as MPEG2 NTSC Interlace before I burn this to a DVD-R. I can't find the setting to change this video setting. I'm really disappointed. Can't TMPGEnc MPEG Editor 3 do this? Is this a software bug? If not, I want my refund. All I'd like to do is simply remove the commercials, and output as MPEG2 NTSC Interlace before burning. Which program can make this output? Please help, thank you.

You can change it to NTSC in the Format Stage under Video Settings-->Aspect ratio.

However, I don't think you can change it from progressive to interlace since that would require re-encoding the whole video...and MPEG Editor 3 is not an encoder; it's only an editor.

Since my aged Athlon X2 needs > 13 hours to transcode a Full HD h.264/VC1 stream to PAL MPG2 with VBR/2passes, I considered buying a Spursengine card (Leadtek) and the TmpgEnc Plugin. However some reports here and there indicate that the encoder settings are somewhat limited when using the Spursengine plugin and also the resulting quality is worse. It also looks suspicious that the CPUs used for comparison are low end to mid range and that the test settings always include additional filters. Besides only numbers for CBR encoding are given and there's no word about limitations or quality issues.
So in a nutshell:

1) How many frames per second will the Spursegine plugin approximately reach for transcoding Full HD h.264/VC1 streams to PAL MPG2 with VBR (1 pass and 2 passes) and high quality settings?
2) Is the quality comparable to that reached by the CPU encoder with the same (or if not possible: high) settings?
3) Is 2 pass VBR encoding possible at all with the Spursengine plugin?
4) Can the motion prediction settings be influenced with the plugin and if not: which is a comparable (quality wise) setting for the CPU encoder?
5) Is scaling done by the Spursengine or the CPU? If it's done by the Spursengine: are all scaling filters (e.g. Lanczos) available?

Sorry can't answer all your questions because but I know that SpursEngine is only capable of 1 pass encoding. If you prefer quality over speed, then you will need to use CPU encoding.
Scaling is done by SpursEngine when you are upscaling SD to HD using the Super Resolution function. I believe it's a proprietary scaling filter that you can't change.

Keep in mind that these are not limitations of the plug-in, but of the SpursEngine hardware itself. Any computer or software that uses SpursEngine will have the same limitations.

Don't know why I didn't think of this before...just go to the specs page for the SpursEngine Plug-In:
http://tmpgenc.pegasys-inc.com/en/product/te4xp_spurs_spec.html

It lists all the available output settings for SpursEngine encoding.

Thanks for the reply. Anyway, I decided to update my system to a Core i7-920 (@3.15GHz) in the meantime and now the conversion flies. It's a speedup of at least factor 5-6 compared to my X2 4200+ with the same quality settings.
I didn't do a fair comparison with exactly the same stream, but my last conversion of an h.264 Full-HD movie to MPGEG2 PAL needed only 1h30min with 2-pass VBR and "high" motion prediction setting.

Admittedly, the update was about 600€ while the Spursengine + Plugin would have been around 230€ I think, but I figure the value for the money is still much higher even if the general system speedup (+increased RAM size) due to the upgrade and the lesser quality settings of the Spursengine are ignored.

Indeed I can barely remember a performance boost of this dimension in any of my last harware upgrades. I guess the only one to come close was that from a 486-33 to a P90 back in the old days.

Hi,
I’m looking for a way to create a very simple DVD project with bilingual audio.
There are no subtitles or chapters.
I have MPEG2 file and two audio tracks in two different languages.
On the menu I just want to have two options “French” and “English”
So how do I trigger different audio options with the same video file.
Is there some templates available for this task?
Thank you
Eric

You can add or change the audio for your video on the clip properties screen (shown when you first import a video or by going to the clip editor).

http://i29.tinypic.com/w9za1l.png

Just select "Multi-audio" and you'll be able to select your two audio tracks.

You may also have to adjust the audio encoding mode and stream format. To do this, go to the track menu settings(1), click on the audio tab (2), and change the Encoder mode and Audio stream format (3).

http://i30.tinypic.com/a3if5e.png

For your menu, you'll have to have at least a track menu page to access the audio selection page. Just make sure to choose "Track menu only" when creating your menu via the menu wizard.

Hi,

I currently own TMPGenc XPress and TMPGEnc MPEG Editor, and for a specific project, I downloaded TMPGEnc Authoring Works.

The purpose of this project is to grab a couple of AVCHD files that were recorded using Sony Handycam cameras (HDR-X100 and HDR-X500), and create Blu-ray discs (BD-R media) without messing with the video itself.
Unfortunately, I don't have the cameras right now, and I forgot to copy the entire folder structure, so I only have the MTS files, and that's what I'm using so far.

In TAU, I'm able to import these files and create a working project and burn it to BD-R media, but the resulting files are always transcoded to MPEG-2.

Is this a limitation of TAU? Does the Blu-ray authoring process only finalizes with MPEG-2 content, or maybe I can change something to be able to use my files without transcoding (re-multiplexing, maybe)?

Unfortunately, as of now Authoring Works 4 can only encode BD's in MPEG-2. I think we are all hoping they add h.264 BD output soon.

I saved a movie to DV after using Windows Movie Maker (WMM) to add titles. The resulting avi, whether I use WMM or Pixella to download it from the camcorder has audio at a significantly slower speed than the video when played by TMPGenc 4.0 XPress (4.2.3.193) on the clip screens, on the encode preview, and on the final encode ac3.

When I play said downloaded movie in WMM, it plays fine, and WMP plays it fine. Using TMPGenc, the movie played fine, prior to adding the WMM titles.

What do I have to do to adjust TMPGenc or do I have to fix the file?

Thanx,
Eski

The video I need to convert is either 1920 * 1080 interlaced (from a AVCHD camcorder) or 1440 * 1080 interlaced (from HDV camcorder).

I want to achieve very high quality at about 12 Mbps.

I would expect H.264 to be the best format (best quality, future-proof standard); however I am a bit frustrated of my results so far compared with WMV9 Advanced Profile (VC1) at the same bitrate ! My perception is that while VC1 gives a somewhat softer image compared to H.264, it does a better job at keeping the details of blurred backgrounds or areas with low contrast ! Yes: for me with full HD at 12 Mbps, H.264 looks somewhat crisper/sharper on foregrounds and contrasted objects, but shows more artefacts (blocky patterns, loss of detail) in the shades and soft backgrounds, and this makes the image globally a bit less appealing to me.
I use H.264 with default settings, except 2 B-frames and CABAC.

I guess I can improve that by fine-tuning some encoder settings, but I find the TMPGEnc Xpress 4 help files lacking good info.

Any suggestions to achieve the best results with interlaced HD video with H.264 (and prove me that it is equivalent or better than VC1) ?

are you using spurs engine h.264 or the normal h.264 in tmpgenc4 ?? But for HD either 1920 or 1440 by 1080. i use 16Mb/s H.264 and the results are fantastic, i think you should just up your bitrate a little try 16MB/s and you'll be fine. for 720p i use 8MB to 11. But then again i like a very clean/crisp image.

There must be something fundamentally wrong with the settings I use, or the setup, because at 12 Mbps, the same clip looks very good with VC-1 and "awful" with MP4 AVC (using the built-in TMPGEnc Xpress 4 encoder i.e. Mainconcept); when I say awful, I mean the kind of result I would expect from a 6 Mbps bitrate, not 12 !
And there seems to be a consensus on the Internet to say that H.264 (AVC) should be equal or better than VC-1 at any bitrate.

Will try a test with X264 and see what I get from that.

As a side note, I have the same difference (in favour of VC-1) with SD material at lower bitrates (1 - 2 Mbps): MP4 AVC looks somewhat sharper for contrasted foregound objects, but really awfully blocky for textured/blurry backgrounds and degrades. Strange b/c the general feedback is that H.264 is less prone to blocking artefacts than VC-1 in the same circumstances....

Anymore ideas ?

I would encode to hd mpeg2 with high hl i think it is, vbr adjust to 800000 on both high and medium, encode to that and then use meguis features.

which allows you to use the mkv settings, which i would go avc auto 3 pass 5.1 level and you can select the siz of file to use.

The preference have options - CUDA
- Use the hardware video decoder?


If I have plugin SPURS ENGINE? - On or off CUDA decoder option?

Thanks

Hello,
I now you have Firecoder blu (based on spurs engine). For normal dvd pal (sd) bit rate 3000 kb/s is good? The quality of image in normal tv color, not plasma not lcd, is good like a commercial dvd?

Thank you

i would only have the cuda option on if you are actually using it ( and you only use cuda for filter options, like sharpening,resizing, ect ) if you are simply encoding i would turn it off as it can make your encode slower. i turn it off and use the spurs plugin by its self.

macchia,

I don't work with bitrate < 8000.

Martin Wichtmann

Thanks

BEST Regards

Need support more 2 languages

THANKS

I'm using tmpgenc4 w/ spurs engine but there are some settings i would love to have that include :

*2 pass variable bit rate ( with spurs hardware mpeg2/avc H.264 encoding)

*2 pass constant bit rate ( with spurs hardware mpeg2/avc H.264 encoding)

*The ability to set any resolution, and not just choose from the avaliable resolutions

*Better quality when using lower bitrates. Encoding SD video using avc H.264 hardware encoding is unacceptable under 5Mb/s [using avc at low bitrates is why h.264 is a chosen codec]. (Although this may be greatly imporoved if the 2pass constant/variable bitrate was implemented using 2-3 Mb/s).

*the abiliy to output avc H.264 hardware encoding with different audio formats not just AAC eg: dolby digital(AC3),uncompress audio(PCM), MP3... ect

*when exporting as Mpeg2 hardware encoding NTSC dvd the ability to export as 3:2 pulldown playback. So 23.976p is played back as 29.97i

*Motion search precision fucntion to be implemented into with spurs hardware mpeg2/avc H.264 encoding

If any of these are in an update, i'm sure more people with buy this product and those who have it like me will get ALOT more out of it.

Regards Martin Wichtmann (africanmarty@hotmail.com).

i recieved a reply ( i sent this same message to the tmpgecn people ) and it reads :

"Unfortunately this is not possible with the current hardware implementation of the SpursEngine. All the settings currently available are what the SpursEngine processor is capable of and since it is a wiredsystem it is not possible to disgress. Maybe a future implementation will provide a more flexible approach into encoding but for now this is all we have."

So its not looking good for any updates soon.

The frame rates for Blu Ray menues are not correct, do not match the values in the global menu settings for 16:9 HD drop down menu, AND do not output the frame rate that is selected. Noticed my motion menues for 720P 16:9 HD were unstable but the actual project played fine. I used a software to analyse frame rates for all M2TS folders in my projects to verify my issue.

For example
1280x720P NTSC 16:9
the correct scan rate should be 59.94 fps. and is not listed in the drop down.
29.97 fps is an option in the drop down. Selecting 29.97 fps actually outputs 24 fps which is not compatible with 1280x720P. thus the playback issues with the menus.

My projects are ruined let alone the money wasted on BD-R media!!!!

The frame rates for all menu parameters need to be checked and corrected. I sent the issue to support over a week ago and still have not gotten a response!

All technical specifications I've seen for Blu-ray Disc say that 24 fps (progressive) is a valid framerate for all HD resolutions.

See section 4.3:
http://www.blu-raydisc.com/Assets/Downloadablefile/bdj_gem_application_definition-15496.pdf

You can try selecting 23.976 fps for your menus which is also a valid framerate.

1280x720P 16:9 broadcast TV
59.94 fps for ntsc
50 fps for PAL

1280x720P 16:9 used for FILM (3:2 pull down)
24 for NTSC
23.976p for PAL

The jobs I have been working on are either converting 50 fps PAL to 59.94 fps NTSC or 59.94 NTSC to 59.94 NTSC broadcasts. You can not use 24/23.976 in place of 59.94/50. 24/23.976 are used for projects shot on film. The 59.94/50 and 24/23.976 are NOT compatible and will cause playback issues.

If you use 59.94 fps for the TRACK you can not use 24 fps for the MENU.

The defaults are correct in your software in the dropdown menu for dvd track menu setting up but not correct for your menues.

the menu settings for 720p in menu settings should be

ntsc progressive

59.94 fps (not 29.97 - this setting is actually outputing 24 fps)
24 fps
no setting for interlaced

pal progressive

50 fps
23.976 fps
no setting for interlaced

FIX IT!

To make the point clearer. you should not mix scan rates... one for the track and another for the menu ...film format for the menu, TV camera/broadcast frame rate for the track... otherwise you will have play back issuses and they are not compatible.

you should not mix scan rates for the menu and for the track. you should not use a frame rate of 24 fps on a motion menu where the source in the track is 59.94 fps.

If the original source has a frame rate of 59.94 fps and you use that source in the motion menu you use a frame rate of 59.94 fps for the track and for the motion menus. you should not use 24 fps for the motion menu and 59.94 fps for the track. There will be playback issues.

the menu settings for 720p menues in menu settings needs to include 59.94 fps for NTSC and 50 fps for PAL. The menu setup currently does not have this setting to accomodate 720P.


ntsc progressive for 720p

59.94 fps (not 29.97 - this setting is actually outputing 24 fps)
24 fps
no setting for interlaced

pal progressive

50 fps
23.976 fps
no setting for interlaced

for 1080i (16:9)
NTSC
1920x1080i 59.94 fps

PAL
1920x1080i 50 fps

for 1080P (16:9)

NTSC
1920x1080P 24 fps

PAL
1920x1080P 23.976 fps

plus all the other possibilities from the PDF.

Please review the issue and fix the software.
