Try running an encode using the default medium preset, then again using one of the fast presets, then again using one of the slow presets. Handbrake gives you access to x264's speed presets (at least the latest version does). They're designed to automatically change x264's advanced settings to give you an appropriate balance between encoding speed and quality/file size (so you don't need to fiddle with advanced options yourself). X264 has it's own speed presets built in. There's many x264 settings which can dramatically effect encoding speed. Which Handbrake preset did you use? The High Profile preset uses the default x264 settings and will probably be the slowest Handbrake preset. Just because you used the same quality setting (CRF value) that doesn't mean all the other x264 encoder settings are the same. I was just comparing the encoding speed, shouldn't the encoding speed be pretty close if it's just a simple transcode with no filters and copy audio ? No. Handbrake does it with proper times, Avidemux does not. There is no excuse whatsoever for Avidemux taking 20+ minutes to render on an i7. Spoken like a true amateur who doesn't know whether to wind his butt or scratch his watch. I really liked it at first for it's simplicity until I found out these astonishing results. I can use a free editing program instead of goofing with Avidemux. I was trying to combine flash clips and it totally warped the audio and slowed down the whole video. Why would I ever touch Avidemux again? For simple editing? It can't even do that. Handbrake always encoded faster with smaller files - H264 high definition. I reproduced the results on a vast number of CPU's. I made sure to check Avidemux settings that it was using all cores. Not only that but Handbrake encoded the file SMALLER by a significant amount. ![]() ![]() I go and install Handbrake and it encodes the same file in under 4 minutes. This was done encoding a 16gb raw video file. I found with certain CPU's the times were WAY off.Īvidemux gave me a pathetic encode time of 24 minutes with a core i7 3770k w/ hyper-threading. Basically I was testing one computer's CPU vs another. I was using Avidemux a lot to test encoding times.
