I havent even got Quicktime on my computer. The project I was trying to finish turned out the way intended. All you have to do is open them with Avidemux, just copy back to avi and it will play anywhere. The new installation is working fine, and it's not opening the wrong file. To solve this, I finally got rid of 2.5.4, tried installing 2.6, saw it was too unfamiliar, got rid of it, and then RE-installed 2.5.4. I've used the "DVD" option many times, and it produces a file that DVD burning programs can work with. Why it went back to a file I'd worked on YESTERDAY and had NOT selected suggested something was wrong with the program. What I said was that the program was, for some reason, going back to a previous file I'd worked on when I selected "Auto/Optical Disc/DVD", apparently DUMPING the file I'd actually opened. Nothing was said in my opening post about trying to make a DVD. I'm wasn't throwing any "off the wall" file in there, nor was I expecting the program to make a DVD, since AVIdemux doesn't make DVDs. I'm guessing you are throwing some "off the wall", downloaded video file in there and expecting it to make a DVD for you? I have 2.5.4, not 2.4.4. Generally the effects of datamoshing are viewed as errors, or undesirable and thus applications like Avidemux try their best to correct these errors and eliminate glitching distortion. filesize) tradeoff of their encode.I have 2.4.4 and that preset is not in there. For this tutorial we’ll be using Avidemux, a free, cross platform video editing application. I think with that one, they're just making sure that mis-informed people don't disable b-frames and worsen the rate-distortion (quality vs. Avidemux 2.7.6 (32-bit) Date released: (3 years ago) Download. (which is probably 16, since that's what x264 allows.) x264's default setting of 3 b frames is apparently good. Aggregated information from all packages for project avidemux. I'm sure their decoder can handle the max consecutive B frames h.264 allows. Download Latest Version Avidemux2.8.1 VC++ 64bits.exe (40.0 MB) Get Updates. However, to get the program to actually start up, I had to delete to files, 'libxml.2.dylib' and 'libiconv.2.dylib'. I have followed all the steps from all the tutorials and I cant seem to find anything wrong. However, I have been unable to get any results whatsoever. They're going to xcode the whole video anyway, so using a 1/2 second GOP size is just going to hurt compression. I have been following datamoshing tutorials for avidemux 2.5.4. Except the GOP of half the framerate, which makes no sense anyway, and is a horrible idea. The encoding guidelines, are all stuff that's on by default in avidemux. There aren't any settings that will make youtube use your encode untouched for even one of its standard resolutions, instead of doing a transcode. (CRF 18 is usually visually transparent, you could go CRF 16 to be on the safe side.) It doesn't matter too much what you use for youtube, as long as you use enough bitrate for it to look good. I made a test encode, and the important settings default to on, which is good. It's pretty essential to have something with a slider for slow to fast presets. I honestly can't recommend avidemux (2.5.4 in Ubuntu 14.04) as a frontend for x264. It doesn't even have a checkbox for more recent (but essential) options like mb-tree, or psycho-visual optimizations (AQ and psy-rd). It's been years since x264 added presets from ultrafast to veryslow, but avidemux still makes you manually choose all the cpu-time vs. Avidemux's dialog box for x264 settings is pretty bad.
