![]() ![]() Your browser doesn’t supporting this video format Īlso, noteworthy video element attributes that I’ve excluded from the above example: preload="metadata" Preloads the video’s dimensions, first frame, duration etc. Try playing around with the bitrate to get a good weight/quality ratio: When converting gifs to videos the quality settings doesn’t matter too much, because gifs are usually pretty shitty looking to start with. The value to use here depends on the size of the video, but try setting it to 500K to start with. See the cropping examples in the ffmpeg docs for more.Īdditional option: -b:v bitrate With this you can control the quality of the video. This math operation: iw/2*2, makes sure that the video’s dimensions are divisible by 2, because an MP4 video using H.264 just needs that. vf filtergraph This defines a filter (an alias for -filter:v) which in this case is using a crop filter: "crop=trunc(iw/2)*2:trunc(ih/2)*2", in which the iw stands for "input width" and ih stands for "input height". We include this option to specify a specific format which has maximum compatibility across all browsers. pix_fmt Pixel format MP4 videos store pixels in different formats. movflags This option optimizes the structure of the MP4 file so the browser can load it as quickly as possible. Here’s what’s happening line-by-line: -i input This flag simply sets the script input, test-gif.gif in this case. You might know this error if you’ve ever installed ffmpeg: Install ffmpegįfmpeg is bolted pretty deeply into the system, on Mac it needs the Command Line tools to function. The above mentioned HandBrake uses ffmpeg under the hood. There’s a great command line tool: ffmpeg that’ll convert pretty much anything to any format. This random 24MB gif turned into a 1MB mp4.ĭownload HandBrake at. You can also drill into the nitty gritty of the setting if you want more control. It’s open source, has solid defaults, and is easy to use. HandBrake provides a nice graphical user interface for compressing, converting, and resizing videos. The main format behind it is WebM and mp4 as fallback. Imgur for example has their own little gifv thingy, that in reality is just a muted video, which auto-plays and loops. Here’s an SO thread if you want to dig more into it. If I understand right, for instance, Linux distributions do not support mp4 out the box, because of the fees. What that means is: although you can freely upload mp4 videos to internet without worrying about royalties, but the companies implementing mp4 to their products need to pay a royalty fee. But, it’s not open source nor royalty free. Unsurprisingly mp4 is the most supported one. Here’s the video formats commonly in use in the web and the browser support: Video format browser support If we’d like to use a video instead of a gifs, the video replacement should more-or-less fill this criteria. "Old tech" does not necessarily equal bad, we still use hammers for example. Videos can act like gifs and have a much effective compression algorithm, videos also don’t need to be fully loaded to start the playback. But gifs were never meant to handle anything else than simple graphics. Gif is an extremely inefficient way to pack video, where as the static gif image is pretty good format for showing graphical shapes with few colors. The technology behind animated gifs is old and clunky, a remnant of the 90s clipart and guestbooks internet. Technologically speaking gifs are in the same club with Macintosh II, Windows 1, and floppy disc. Graphics Interchange Format, invented in the late 80s, still persisting in our daily lives. It also has a Publishing feature, so you can auto-upload the results to YouTube.I originally wrote this post in 2015, but I’ve now (2020) rewritten it. Very helpful if you need to export multiple clips or multiple versions. I like Squeeze Pro becauseit has a Watch Folder feature. All of these run rings around QT's H264 encoding, both in speed and quality. Usually, in practice, it is MUCH faster to do a Same-As-Source export from MC, or a QT Reference export from MC, then use a modern 3rd party encoding application like Squeeze, ProCoder, TMPGenc, Compressor, Adobe Media Encoder, HandBrake, or whatever you want to use. Third downside is that you have very limited control over the H264 settings. The second is that you will be using the Apple H264 codec, which is notorious for its gamma shifts. One is that it is incredibly slow, because QT is an old 32bit application (your specs mention a z840, QT will only be able to use a fraction of the processor power of your high end workstation). This has three very negative consequences. If you use Custom QT export settings in MC, you will in fact be using the Quicktime engine for the encode. The issue is that MC does not handle the H264 export itself. ![]()
