Fantastic program!!!! My personal fav among all i've tried. Would give full marks but i have yet to find an option to encode ALL audio Streams in a single video at one time. it seems to only encode one audio track per video... HUGE problem IMO. Only complaint

Review by PoE on Jul 14, 2018 Version: TX264 0.9.8 fixed OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 8/10 Value for money: 10/10 Overall: 9/10

This program is easy to use. The options are clear. The conversions are fast and the results are excellent. Thanks to the author for a great program!

Review by gus gusimio on Feb 2, 2016 Version: 0.9.8 build 3219 OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

Best tool for the job, it helped me batch encode video+audio and remux a set of files.

There's room for improvement though, it had problems with some audio streams:
Codec ID/Info : QDesign Music 2
Codec ID/Info : VoxWare MetaSound

I also miss some expanded functionality, like filter input list by file type. Probably allowing explorer capabilities of sorting, highlighting and removing files can be a good idea. Saving jobs in text format files can come handy too, as well as a checker to whether remux or just keep raw streams.

Despite this it's probably the best GUI encoder out there.

The best program there is for encoding,easy to use and the support is perfect

Review by Ridder on Apr 26, 2013 Version: OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 8/10 Value for money: 8/10 Overall: 9/10

GREAT program,,the best encoded,compliant HD quality movie and completed quickly,around 40 minutes average to encode a 90 minute movie..I would give the program a 10 but is uses Aften to encode to ac3 instead of ea3to.. And I refuse to use the internal aac encoders because in my opinion apples aac audio codec sucks at any bitrate..The aac codec removes alot of the deep base sound that most people like to listen to through their HD recievers...;)~
