![]() If the CPU temperature were to climb to dangerous levels in case of a fan failure or if the fan grill was full of dust or lint, the computer will shut down before any damage can be done. Moreover, macOS monitors the CPU temperature as well and modifies the CPU speed and fan speeds accordingly. With 80 billion pixels, that’s a lot of detection!Ĭomputers are, however, built to work - the CPU is built to withstand long periods of time working at full speed without any damage. That’s why modern formats look for pixel movements. Just think about it - with a 720p video that’s 1 hour long, the computer needs to process about 80 billion pixels! (1280 x 720) x 24 frames per second x 3600 seconds in one hour Moreover, with videos, it’s not as simple as just writing one image after another - it would be highly inefficient. Video conversion is a very CPU-intensive task. This is absolutely normal and there is nothing to worry about. ![]() There is no way around it, not doing so would result in a file unreadable by most video players out there.ĭuring the postprocessing, you may notice that the fans of your computer go off and the Activity Monitor may report e.g. These chunks need to be put together using a conversion. Similarly, many sites use M3U8 (HLS), DASH or F4M (HDS) manifests, which describe videos that are split into dozens, sometimes even hundreds of little files called fragments, each containing a few seconds of the video.Without it you’d end up with two files instead of one - one with just the sound, one just with the picture. YouTube often splits the video into separate video and audio files - the conversion is then necessary to put them together.In general, there are two cases where this needs to be done: There are downloads that require postprocessing the downloaded video even when the postprocessing option is set to None. Postprocessing even with the option None selected using the browser extensions - right-click anywhere on the webpage and select the option to send the current link to Downie with postprocessing set to the desired option.each downloads has a popup button with postprocessing options.via keyboard shortcuts equivalent to the commands in the afore-mentioned menu.There are several ways to change postprocessing. ![]() If the task takes more time to be completed, consider reporting progress to Downie in form of standard output downie_progress(0.75) or downie_progress(0.75, Uploading.) if you want to be able to see the status string. Please keep in mind that the script runs inside Downie’s sandbox and you won’t be able to access some OS features, such as disk management, etc. upload the file to your cloud, perform actions based on where the file comes from, etc. Custom - for even more control over the postprocessing actions, you can create your own custom postprocessing as a shell script.For these users, we’ve added integration with Permute - our media conversion utility. Permute - More advanced users might want to have more control over the target format that Downie converts the video to.By default, the audio file is converted to MP3, which can be turned off in preferences. Audio Only - Only audio will be extracted from the file or in some cases, if available, an audio-only track will be downloaded.Files already downloaded as MP4 will be left intact. MP4 - The downloaded file will be converted to MP4 (H.264 video format) which is playable in QuickTime Player and on most current mobile devices.Note that Downie may perform some postprocessing on its own even if this option is selected. None - This will leave the file as-is with no further postprocessing is done.For all these scenarios (and many more), Downie includes postprocessing, which allows you to apply post-download operations on the downloaded files.ĭownie comes with the following postprocessing options: Or perhaps you want to download something as audio-only. QuickTime Player or your iPhone, however, won’t be able to play this format. For example, some YouTube videos come in the WebM format. Not all content on the Internet is in the format that you want.
