I have a NVIDEA CUDA enabled graphics card. I noticed that there are three Video Encoder options for encoding to a MPEG-4(AVC)file. The options are as follows:
- CUDA
- Intel Media SDK Software
- x264
I want to take advantage of improved processing acceleration by using CUDA with my NVIDIA graphics card but I also want the file to be encoded using the H.264/AVC encoder. Therefore if I select CUDA, will the output file still be encoded with the H.264 encoder? It is unclear to me since there are no additional options for selecting the H.264 encoder if I select CUDA.
Based upon the description of the "NVIDIA CUDA H.264 Encoding" option, as described on the PEGASYS website (and as shown below), I am assuming that if I select CUDA the file will still be encoded using the H.264 encoder?
NVIDIA CUDA H.264 Encoding.
Not Just for Filtering Anymore.
In addition to CUDA-enabled filter processing and decoding, TMPGEnc Video Mastering Works 5 supports H.264/AVC file output using the CUDA technology provided by NVIDIA. The CUDA technology makes use of the GPU (graphic board CPU) with multi-core parallel processing to process complex calculation problems in a short time. By splitting the processes into parallel elements, and using the massive processing power, the program can run even more effectively. Using this function with a compatible graphic board improves processing acceleration when compared with CPU-only use in most cases.
I'm not quite sure if I understand what you're asking. Each one of those 3 are H.264/AVC encoders; you are selecting the H.264 encoding engine. If you want to use CUDA for H.264 encoding, then select CUDA and it will use CUDA's H.264 encoder.
Selecting the other two will use them as the H.264 encoder, and CUDA will only be used for filter processing.
From my recent reading about CUDA 2/2013 there is a serious trade-off in image quality for the limited speed gained by using CUDA. If you know of actual image quality improvements, then please post to this thread or start one about it detailing exactly how to do this.
I've yet to read where CUDA is improving image quality at the high-end of HD.
I'll ask the same about filters too... does anyone know which CUDA filters equal or improve image quality over CPU vs GPU/CUDA saving time but getting a lower quality image.
I'll also mention, the CUDA SDK is up to version 5.0+ at the NVIDIA website, but I think TPMG5 is only using version 3.1 SDK CUDA as of 2/2013... anyone know otherwise?
Anyway, please report about image quality improvements using CUDA and saving encoding time. Which filters specifically... which NVIDIA card you need to do it too... I'm currently very skeptical about CUDA having read a few detailed articles of recent CUDA software reviews. That's 3-4 years now of development time without much gain, if any, in high-quality output from the reviews I read.
I have tried convert a AC3 audio file to PCM audio file but when PCM arrive to 4GB Tmpgenc show a error messaje: File Exceeds 4GB... And conversion is finished. Why?.
Standard WAV files are limited to 4GB because they are a 32bit format.
Only 64bit formats can go above 4GB in file size. These 64bit formats are typically only used in the much more expensive professional editing softwares.
New update! New output templates for PS Vita and the new iPad, plus they updated the x264 encoding engine.
It also seems to fix errors I was getting with the latest NVIDIA drivers installed.
at list they fixed those error with nvidia 306.23
My wish is more plugins and please add video stabilization like "MERCALLI", no one make plugins for this software so i have to use another software
I use tmpgenc all the time and I'm always eager to get the latest fixes and features. Unfortunately, pegasys doesn't bother to alert you when an update exists. And for some bizarre reason, you can only check for updates while you're editing a project.

Currently decoding & encoding in TVMW 5.0 can be accelerated by using CUDA. While gaining the speed, CUDA processing is not that great in terms of quality to compare with CPU only. Hardware acceleration with similar to CPU processing quality can be achieved by using Intel Quick Sync technology. There are currently only several programs that can use this technology, like CyberLink Media Espresso 6 etc.
Would be great if TMPGEnc VMW 5.0 is one of those programs too!..
Check Preferences->Input/output format list->Intel Media SDK (Hardware). You should see "+" for Input and Output. If not, make sure the onboard GPU is active (sounds like you are also using a discrete NVIDIA GPU). You should see the "Intel HD Graphics" icon in the system tray. Normally you need to have a monitor plugged into the onboard GPU for this to be active. Motherboards that support Lucidlogix's Virtu technology can activate the onboard GPU with a single monitor connected to the discrete GPU. That said, I was not able to get this working with TVMW5, so I uninstalled the Virtu drivers, and plugged a "VGA Dummy" into the onboard GPU. I purchased one from EBay, but you could probably make one for a few dollars. Hint, you can setup your multiple displays so that the "fake" monitor touches the real ones in a corner, that way you can still do the Windows 7 drag and snap functions.
I purchased TVMW5 for the sole purpose of encoding 1080i STB captures to 720p using QuickSync, and it does a great job IMO. One-hour programs take 30 mins, about 4X faster than the single-pass x264 software encoder, with comparable quality (if you give it enough bandwidth). This is on an i5-3570K under Win7. TVMW5 seems to be finicky on the Intel driver version though, I remember having to re-install an older driver when an Microsoft's auto-update pushed a new driver onto the machine.
Intel needs to do a better job promoting Quick Sync support in video tools, it really is a killer feature in Sandy/Ivy Bridge CPUs, and like you mention, there are few applications that utilize it reliably at the moment.
Ironically, I came to this forum looking for CUDA issues. I just got a GTX 670, and while CUDA is recognized, it is not utilized (during encoding, load is split CPU/GPU: 100%/0%, which wasn't the case before. I am using the GEFORCE 306.23 driver from last week. Reverted to 301.42, same results.
Thank you for a great answer! I have a i7-2600K processor on a Z68 motherboard with a discrete video card GTX 570 (now a single monitor is plugged into it...) I don't know, what format 1080i to what format 720p you are trying to convert... I have a great success using CUDA decoding and encoding only AVCHD files (CPU/CUDA up to 30%/70%). When I deal with MPEG-2, CUDA does not help.
I will try to switch my monitor to the MB video output just to check if it works. Do I have to also adjust BIOS for Quick Sync to become active? Then if it works I might connect a second monitor (I don't have one...) Never heard of VGA-Dummy though...
Most motherboards will by default auto-enable the onboard GPU if a PEG device (PCI Express Graphics) is not found. Since you have a discrete GPU, you might want to force it on in BIOS. Then again, plugging the only monitor into the onboard GPU might override this. The BIOS may also have a RAM setting for the onboard GPU. In my experience, this doesn't have any affect and is not reflected in the Intel GPU driver information, but if you got lots of memory, it doesn't hurt to maximize it.
I mis-read the encoding Status display in TVMW5. The CPU/GPU load shown is only for the filters, not the encoding stage. Since the only filters I have are the default resizer/deinterlacer, neither of which are CUDA-accelerated, the load will always show 0% for CUDA. To test this, I added a Sharpness @100 (to make it obvious), and the status now reads:
... Pre-processing (CPU=15.4%, CUDA=84.6%)
Instead, I tried monitoring GPU load with GPU-Z. With CUDA encoding, it registers about 10% on the GTX 670 (about 4% for the Sharpness filter mentioned above). Tried it again with a relatively weak GT 430, and the GPU load was 60%, which makes me think TVMW5 does not utilize all the CUDA cores available.
My source files are H264 in a MPEG-TS container (HW:Hauppauge HD-PVR, SW:SageTV/MediaPortal), target files are AVC/H264 in either MP4 or MKV containers. I think all the hardware encoders only come into play during H264 compression, probably because CPUs have become fast enough to deal with MPEG-2 with reasonable speed.
I agree, for a given bitrate, QuickSync results in better image quality than CUDA, and is the preferred encoder given a choice.
@rasterX
Thank you for the good explanation. I'm currently evaluating MW5 on my Notebook - equipped with an Intel Core i5-2520M but I cant get QuickSync enabled. MW5 says its available but not usable. My Notebook as no discrete GPU and I've already tested it with external Monitors aconnected.
I have a Sony PMW-EX1 camcorder, which records files in MP4 container using MPEG-2 codec. Currently, if you trying to input those files to TVMW 5.0 only audio part can be seen - video is missing. Also, if the duration of the recording exceeds ~13 min., clips separate due to 4GB limit of FAT32 formatted cards used by the camera.
Would be great, first, to be able to input XDCAM EX MP4 files, and second, merge those separate chunks of 4GB or less in size back into 1 long file seamlessly. This could be achieved with the help of Sony XDCAM Browser (it does the merge) if it is launched within TVMW 5.0.
I'm a bit lost trying to get a blu ray menu to work the way I have it in my head.
I'd like it so that when the disc is inserted it automatically plays a short 10 second or so intro clip. This then fades to black and then a different 15 second clip fades in and plays, over the final frame of which the video stops and the disc menu appears.
Can this be done with Authoring Works 5 and if so how?
You want to create a First Play Track. In the Source stage, click on the arrow next to the "Add a Track" button on the left hand side of the screen. Select to add a first play track.
The first play track will play once you put the disc in the player, then the menu will appear after it.
So you'd want to put the clips you mention into the first play track, and then add transition effects for your fades.
Cool, thanks for that. Next stumbling block. After playing the first play track the disc immeadiately goes on to play Track 1 rather than go to the top menu. I've got the playback settings set to "Play the header track only" at disc insertion and and "display the track menu or top menu" for track playback end action (I only have a top menu), but it refuses to go to the top menu without user input.
Your disc insertion action should be set to "Display the top menu". I think the header track refers to the first actual track, not the firstplay track. The firstplay track will always play first no matter what insertion action you use.
I created an AVCHD movie and in the output section set the target size to a single layer DVD. In disk writing tool it says the output size is 4478 megabytes and refuses to write to the disk because there is insufficient storage size. I have reprocessed this movie and it comes out the same size again. Why is the program not compressing the files adequately, or if it is, why will disk writing tool not write the file.
From what I've read from other peoples' experiences, that tool is a bit hit and miss. I think people have reported it going slightly over or under the target size.
You may want to try setting a custom target size a little lower than the actual DVD capacity.
