All,

Hardware acceleration means much faster compression and conversion in DVDFab. Recent improvements have made it even better for more users thanks to new updates to include new abilities for users of AMD GPU video cards, effective with DVDFab v10.0.3.7 Beta. Please see below for details.

Information for the Nvidia CUDA and Intel QuickSync (IQS) sections is being updated as well.

[SIZE=3][U]Nvidia CUDA

[/U][SIZE=2]We will begin with Nvidia CUDA, the GPU acceleration most widely used by DVDFab customers.
To be able to understand the following information you should find out a number for your GPU called the Compute Capability or cap value which is available from Nvidia here.

[/SIZE][/SIZE]1. CUDA H264:

If your GPU's CUDA cap number is

Less than 3.0
- you can get encode+decode support by installing the version 337.88 driver, which is available from Nvidia here: http://www.geforce.com/drivers/results/75991
- you can use a newer driver but support will be for decode only
- get more details here: http://forum.dvdfab.cn/showthread.php?t=25674

Greater than 3.0
- install the newest driver for encode+decode support and select CUDA in DVDFab Common Settings

2. CUDA H265
If your GPU's CUDA cap number is

at least 3.0 but less than 5.0
- use current driver, but support is decode only for Windows 7, 8, 8.1. No support for Windows 10 presently.

5.2 or greater
- use current driver, encode+decode support for 950, 960, 970, 980, 1070 and 1080 and the corresponding M versions of these cards. Due to lack of support in current Nvidia SDK and driver, Win10 currently supports only encode for 970 and 980, but supports decode+encode for 950, 960, 1070 and 1080 cards.

[SIZE=3][U]
Intel QuickSync (IQS)

[/SIZE][/U][SIZE=3][COLOR=Black][SIZE=2]To learn more about IQS in general and check for supported CPUs, click here.[/SIZE][/SIZE][/COLOR][COLOR=Black]

First, make sure you are familiar with the procedures for enabling IQS in DVDFab on your system. Read more[SIZE=2] here [/SIZE][/COLOR][SIZE=3][COLOR=Black][SIZE=2]and in the thread that follows that post. Note that many of the issues raised in the thread were resolved long ago, but it still contains good information and may be helpful.
[/SIZE][/SIZE][/COLOR]
1. IQS H264

[SIZE=2]Decode+Encode support with 2nd, 3rd, 4th, 5th or 6th Generation CPUs with Intel HD Graphics with QuickSync[/SIZE]
[SIZE=2]Just follow the instructions for setting it up with DVDFab in the forum post linked above, then enable it in DVDFab Common Settings. With recent drivers, DVDFab should find it automatically and it will appear on the AV Codec page for you to select[/SIZE]

2. IQS H265

[SIZE=2]This powerful mode requires a 6th generation "Skylake' series CPU or later for full decode+encode support[/SIZE]
[SIZE=2]For 4th and 5th generation CPU with HD Graphics 5500/5000/4600/4400, Iris Graphics 5100 or Iris Pro Graphics 5200 will support decode only, but will not be available when converting H265 source to H265 output, but IQS Lightning Shrink will use it when converting H265 source to H264 output[/SIZE]

[SIZE=2][SIZE=3][U]AMD APP

[/SIZE][/U][SIZE=3][SIZE=2][COLOR=Black]Effective with DVDFab v10.0.3.7 Beta, support has been improved and added for users of AMD graphics processors. This includes hardware acceleration for h264 and (encoding only) h265. Support for h265 decoding can hopefully be added in the future. Here are some of the basic requirements to be able to use AMD APP products successfully with DVDFab:
[/SIZE][/SIZE][/COLOR][/SIZE]

[SIZE=2]Hardware acceleration works only if your PC uses Windows 7/8/8.1 or 10 and it and your card can use [/SIZE] AMD Radeon Software Crimson Driver 17.1.1 (16.50.2611) or later
Your PC must use the following AMD hardware and DVDFab v10.0.3.7 Beta or later. In the list below, card models shown in black are h264 only, those in blue[COLOR=Black] support h264+h265.[/COLOR]

[SIZE=2]Note: H265 decoding is not currently supported for any of the listed cards but will be added soon.

The selection of using AMD APP for decoding and/or encoding is made on the AV Codec page in Common Settings as it is for CUDA and IQS. If for some reason your selection is not supported, DVDFab will provide a message to inform you. Remember that all hardware drivers are sensitive to the OS version and updates for it that you have installed, so check to see if your OS is updated and stable and if the problem persists,start anew thread about it or look through the forum to see if other users have experienced it or found a solution. Before you post about your problem or contact email support, please download and run the AMDCheck utility and supply that result and the FabCheck logfile by attaching it to your post or the email that you send to the Support Team in Beijing.

AMD hardware acceleration will provide you with much improved speed compared with the Software setting with great video quality.

This information is current as of 6 May 2017 with DVDFab v10.0.3.7 Beta and may be updated from time to time. If you have a problems or questions with hardware acceleration in DVDFab, post in this thread and attach the DVDFab internal log session, the DVDFab FabCheck log session (and run the AMDCheck utility and attach the output if using AMD) that relate to the problem. The AMDCheck utility can be found in the zip file attached to this post.
