Note that so called “single pass” encoding can result in a less good quality or less efficient compression when compared to “multi pass” or “double pass” encoding – but that doesn’t have to be the case. It will only increase the file size but most certainly not increase quality – and probably even make the quality worse. High bitrates do not guarantee quality but seriously impact file size.Īlthough in general there is a good correlation between quality and bitrate, a higher bitrate is not a guarantee for quality.įor example when transcoding a existing MP4 file with a low bitrate, to an MP4 with a high bitrate is total nonsense. For example: older devices that are h264 capable might not yet support the newer “options” of this codec, resulting in crappy or even unplayable files. These settings or options can also be the root of all problems. The compression settings can make it that an old MPEG-2 codec can actually out perform a modern codec like h264. Some codecs (en Coder/ Decoder) are more efficient than others when it comes to compressing and storage. The common containers (AVI, MP4, MKV) typically support a variety of so called codecs (en Coder/ Decoders) and the selection of the codec is what influences quality and file size.Ī great codec is not a guarantee for quality but has a great influence on file size. MKV is (in my humble opinion) better, but not as widely supported. AVI is widely supported but MP4 is definitely the strong upcoming format to use. ![]() Therefor I’d recommend using the container that is most compatible with your devices and/or software. Since the “container” file has a minimal or even negligible impact on file size or quality. The chosen file format, or “container”, has hardly any effect on file size or quality (MP4, MKV, AVI). So based on personal experience (note that I’m not an expert) a few pointers: The times that encoding a movie from DVD took 8 hours are long gone, most of my computers can convert a DVD easily under 15 minutes. The time to encode a movie should be irrelevant – sometimes the time difference is really not worth it, for a few minutes extra you will get a better quality and/or smaller file size. Personally I believe that fine tuning should be a balance between file size and quality. ![]() ![]() Now you should have a much smaller file than before.Optimizing or fine tuning of video encoders comes basically down to: Im just gonna set it to my desktop.Īfter you have done that, just click Start encode and wait until its done. Now, finally you can choose your output directory. Set "Encoder Tune" to "None", uncheck "Fast Decode", set "Encoder Profile" to "Auto", set "Encoder Level" to "Auto". If your cpu is bad, use "Slow" or "Slower", i recommend to use "VerySlow" for anyone that has a good amount of cores and time. "Ultrafast" looks bad and will make the file bigger, while "Placebo" will take forever on slow cpus, but it will look the best and be the smallest. Now set the "Encoder Preset", this is another tricky part. My input is a 1080p video so im gonna choose an RF of 24.Īfter that you gotta set your video optimization under "Optimise Video:" It's recommended to never go below 18.īelow are suggested ranges for some resolutions: The slider will set how lossy the video is. ![]() If you did that set "Constant Quality", thats a tricky part. I wouldn't recommend using H.265 for that reason.Īfter that, set the Framerate (FPS) to "Same as source" and to "Constant Framerate". Now set Video codec to H.264, yes, i know that H.265 (HEVC) is smaller, but on some devices it cant be played efficiently, for example Intel 5th-gen cpus or older and amd 5th-gen cpus or older. The first thing you want to do is set the format to MP4:Īfter you did that switch over to the video tab. After dragging your file into the window or selecting a file you should see something like this:
