Dear Everybody

I wonder if someone can help me to discover which is the best codec to convert in .AVI file because I've been trying JPeg, Radius and Intel and the final result over the clip is not good; a lot granulation and many pixels. The source is .AVI
My O/S is Win XP Pro SP3; Intel Pentium CPU 2.80GHz, 4.00 GHz in RAM


Thanks
Carlos

You need to find out what the video codec is first. AVI is a container format, so the video stream can be anything. Use a program like MediaInfo to find out what the video codec is and then download the appropriate codec.

Hey folks,

I have got a problem. I have a clip that I need to split into several shorter clips. Splitting itself isn't the hard part - I figured that out and now I have multiple clips. But when I come to render the file - it will still produce the one huge video, right?

Is there an easy way to render that project into several video clips? And if not - how does the harder way look like? Just save the project, cut out all the other parts and then render the first part, then load again, cut the unwanted and render the second and so on?

Any help is appreciated!

If you are editing in Normal mode, there is an option in the Format Stage called "File Output Mode". There, you can select the option to output each clip as a separate file.

If you are editing in Timeline mode, you will need to put each clip into its own layer. You can then easily isolate a single layer by activating the Single Mode button (the "S" button for that layer). I'd suggest using the batch output for this method because you will need to go through the Format and Output stage for each layer you want to output.

Woah, thank you very much, your help is appreciated!

Before buying TMPGEnc VMW5 i used 4.0 version. The problem is that DMW4 way faster encoded do DVD from oryginal mpg format than newest version I've installed on the same system.

It seems to force encoding each file, when DMW4 used (I think) original mpg to burn on disc (of course when it fits media without any compression to 4,7 GB). For example VMW5 encode 30minutes mpg approx. 30 minutes when VMW4 encoded in only few minutes.

What's the difference or when I have to search appropriate setting.

I think you bought the wrong software. It sounds like the older software you're describing is TMPGEnc Authoring Works 4. You should have bought Authoring Works 5, not Video Mastering Works 5. TVMW5 is an encoder/converter, so it re-encodes everything.

I think I bought right software. I have trial of Authoring Works 4and when i decided to buy it was to late becouse version 5 appers, so I bought Authoring Works 5.

Problem is tahat, I'm recording from TV with Pinnacle software which record in mpeg format. In version 4 I made approx 1,5h DVD disc from this recorded source in just few minutes, and with version 5 the same disc is made nearly 2 hours!

It looks like ver.4 didn't encode source when it fits to disc without compression to disc size, and ver.5 endode all source material. It's frustrating to be honest and much dissapointing when you buy software.

Ok, never mind. Now I see I wrote my problem on wrong forum. Sorry for taking time.

I found something I hope you can correct. The files I'd like to edit are created using Hauppauge Colossus hardware and the bundled ArcSoft Showbiz showbiz software. They're a mixture of MPEG-2 TS container, MPEG-2 AAC audio using ADTS and MPEG-4 AVC video. Smart Renderer 4 has no problem opening the files but when I try to save them in a new MPEG-4 MP4 container, it warns me that "MPEG-2 AAC (LC) is not a common audio stream type in the MP4. Therefore some players may not playback the video." I did some research and found out that MPEG-2 and MPEG-4 AAC are identical except for some header information. One common tool MP4BOX has been quickly modified to make a lossless conversion. See http://sourceforge.net/projects/gpac/forums/forum/287546/topic/1809366 and http://www.hydrogenaudio.org/forums/index.php?showtopic=57074. Could Smart Renderer be patched to do something similar while smart rendering AV files, losslessly converting from MPEG-2 AAC to MPEG-4 AAC when being saved to an MP4 container?

I enabled cuda cores and they sit at 0.0% for every project I finish

I got my issues worked out getting TAW5 to recognize audio streams correctly by converting them to ac3. However, Now when I edit clips and chapters there is no audio. The same holds true when clicking simulation. The videos play, but no audio can be heard. It seems that the only audio I can hear is when I use a video that has stereo sound. what gives? I must say, TAW5 is turning out to be a big disappointment.

Hi,

When I was adding my clips into authoring works to create a DVD it stored the files on the HDD in the export folder.

At the time the HDD had the drive letter as E: and this has now changed. How do you amemd the file location in a saved Project?

Thanks

Just open the file in TAW4. An error window will show up for each missing file; in the window, click on the "Browse..." button and select the file in it's new location.

When I extract an mpeg2 m2ts file from a home generated Bluray Disc, TAW5 wants to rerender it. Is there a way to determine why it won't smart-render the file? The file is generated by ProShow Gold.
Please help...I've pulled out most of my hair....

give us the video properties. GOP structure over 30 along with mbaff nonmbaff coding causes issues in regards to smart rendering in tmpgenc software. I have the same issue with files outputted by our HDPVR.

When I import MKV files, there is no audio when I go to edit them. why doesn't the audio from the file import into a project?

It may be an audio format that is unsupported or you may not have the right codec for it. Use a program like MediaInfo to find out what format your audio stream is in.

It's in dts which is supported. Whats odd is I have a bunch of vids I've put together in ac3, dolby digital, stereo, mono, and with mkv files none of the formats are even recognized.

DTS is not native supported by TAW5, you have to tweak a little to get the support by installing FFDSHOW and Haali Media Splitter and then first make some changes in FFDSHOW's audio settings:

TrueHD to libavcodec (to get Dolby True HD support, explanation why will follow)
DTS to libdts
Uncompressed to all supported

After that you have to tweak TAW5 to use FFDSHOW and Haali by going to TAW5's input plug-ins:
Options => Preferences => Input/output format list => File input plug-in.
Here you must remove every marker, but not the one at DirectShow file reader.

When this is done, DTS and Dolby True HD support in TAW5 has been established.

Reggarding Dolby True HD and DTS-HD Master:
People have figured out how to put the HD audio from Blu-ray's in to MKV files. Lately, i have come across several MKV's with both Dolby True HD and DTS-HD Master audio in them.
The adjustment explained above for FFDSHOW will give you the support for Dolby True HD.
DTS HD-Master is not supported though. That audio type you will not be able to open in TAW5, because FFDSHOW does not deliver support for it. It only delivers support for standard DTS, the one who is also used on DVD's.

I've completed all that and was able to get the software to recognize the audio. However, it doesn't recognize it correctly. It recognizes DTS as 2 Chanel stereo. Mediainfo and tsmuxer specify the audio as DTS

>I've completed all that and was able to get the software to recognize the audio. However, it doesn't recognize it correctly. It recognizes DTS as 2 Chanel stereo. Mediainfo and tsmuxer specify the audio as DTS

You need to disable mixer in the FFDSHOW filter, then it will show as 5,1

that worked.. Thanks. Now I just got to figure out why there is no audio when I use the simulation or chapter edit features.

New to Smart Renderer. Trying to figure out how to adjust bit rate to bring video size down. I video my kids clubs soccer games and files are 6/8 GB and need them to be smaller for S3 storage.

Smart Renderer 4 is not a video converter; it's made to keep the output the same as the input as much as possible.

However, there are ways around it using the Rescue clip function. You need to have an existing MPEG file at your desired bitrate and use that file as the Master clip. Your new video will then be re-encoded to match that clip.

Evaluating TAW 5 using trial version. Load 3 TS files form a Canon HFG10 camcorder. Create top menu on track page and a pop-up menu. Create BDMV output. TAW appropriately re-encodes a few pieces to put the watermark in but otherwise shows "lossless". Burn disc. Put in Panasonic BR player and it stops during reading saying "incompatible format".

Any ideas what may be wrong? Ths player plays anything from TS Muxer and Total Media Extreme. when it burps it seldom gives an error message.

TIA for any ideas.

All set, bad burn speed or TAW burner probs. burned project with Imgburn at 6x all is well.

My BD recorder is old (GGW-H20L), but once I step TAW5 burn well for PC, but my BD-Player did not read it, I saw that the recording was minimally smaller, TAW4-5 perform shorter recording (Lead -in and lead-out) for DVD and BD.
Currently recording with Nero UDF BD-R-ISO 2.5 (physical partition), and update my firmware on the recorder to the YL07 version (11th May, 2011). although it is not very compatible with LTH disc or cheap versions. works with BD-R DL (check their website MYCE Club)

Are there any plans to add support for nvidia's new NVENC hardware like whats in gtx 680

NVENC

All Kepler GPUs also incorporate a new hardware-based H.264 video encoder, NVENC.

Prior to the introduction of Kepler, video encoding on previous GeForce products was handled by encode software running on the GPU’s array of CUDA Cores. While the CUDA Cores were able to deliver tremendous performance speedups compared to CPU-based encoding, one downside of using these high-speed processor cores to process video encoding was increased power consumption.
By using specialized circuitry for H.264 encoding, the NVENC hardware encoder in Kepler is almost four times faster than our previous CUDA-based encoder while consuming much less power.

It is important to note that an application can choose to encode using both NVENC hardware and NVIDIA’s legacy CUDA encoder in parallel, without negatively affecting each other. However, some video pre-processing algorithms may require CUDA, and this will result in reduced performance from the CUDA encoder since the available CUDA Cores will be shared by the encoder and pre-processor.

NVENC provides the following:
 Can encode full HD resolution (1080p) videos up to 8x faster than real-time. For example, in high performance mode, encoding of a 16 minute long 1080p, 30 fps video will take approximately 2 minutes.
 Support for H.264 Base, Main, and High Profile Level 4.1 (same as Blu-ray standard)
 Supports MVC (Multiview Video Coding) for stereoscopic video—an extension of H.264 which is used for Blu-ray 3D.
 Up to 4096x4096 encode

We currently expose NVENC through proprietary APIs, and provide an SDK for development using NVENC. Later this year, CUDA developers will also be able to use the high performance NVENC video encoder. For example, you could use the compute engines for video pre-processing and then do the actual H.264 encoding in NVENC. Alternatively, you can choose to improve overall video encoding performance by running simultaneous parallel encoders in CUDA and NVENC, without affecting each other’s performance.

NVENC enables a wide range of new use cases for consumers:
 HD videoconferencing on mainstream notebooks
 Sending the contents of the desktop to the big screen TV (gaming, video) through a wireless connection
 Authoring high quality Blu-ray discs from your HD camcorder

A beta version of Cyberlink MediaEspresso with NVENC support is now available on the GeForce GTX 680 press FTP. Support will be coming soon for Cyberlink PowerDirector and Arcsoft MediaConverter.

We are also requesting NVENC hardware encoder support.

Just bought a GTX 650Ti video card, I hope for a support NVENC too. Please :)
