No Progress bar active in x264 second pass.

Jul 25, 2017 Version: 2.6.21 OS: Windows 7 64-bit Ease of use: 6/10 Functionality: 7/10 Value for money: 10/10 Overall: 7/10

Horrible, crashing, hangs what a pice of garbage.

Jul 24, 2017 Version: Newest OS: Windows 10 64-bit Ease of use: 1/10 Functionality: 1/10 Value for money: 1/10 Overall: 1/10

I had to knock off a few points because version 2.7 won't allow me to resize videos. Mediainfo shows it as a 2:3 video even though it was saved as a 16:9 video. Mediainfo also shows it used to be 16:9. Yes the configuration settings were changed every way I could think of, but still no go.

I also tried saving hevc x265 video, and it took over an hour to save a 10 minute video, normally takes 5 minutes in 2.6.21. The files size was only .001 mbit less than the same x264 mp4 video.

Needless to say I won't be using version 2.7 until the resize is fixed, and no x265, until I can see some advantage to it. I would post this on the avidemux forum but I don't have membership, and I don't have internet at home.

On the other hand I would give AVIDEMUX 2.6.21 all Stars, even if minor improvements might help. I use it for everything!

Jul 2, 2017 Version: 2.7.0 OS: WinXP 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 7/10

Well can't rate this version. I like using Portable x64 version. Since version "AviDemux 2.6.18 r170219 Nightly" other versions don't even run and give me Error Loading Message. I am assuming after version 2.6.18 the program is NO longer compatible with Vista version ... just a guess on my part. Thanks!

Jul 2, 2017 Version: 2.6.21 OS: Vista 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

The amount of frequent bug fixes can be looked at in two ways, the program is in constant development or the code just isn't up to scratch. I prefer the latter description! I have never ever managed to complete an encoding on any Windows platform using this tool. The frequent updates to a stable build prove it has never been tested thoroughly before a 'final' stable build. That said the so called stable builds can crash too!
