What are the best ways to lose weight?
Losing weight is not a very difficult thing if one regularly follows a routine a proper diet chart; and does exercises. If you think that you need to lose weight first you have to change your food habits. For that it is better to consult a dietician who can provide you a proper diet chart which you should follow every day. Try to eat healthy food such as green vegetables fresh fruits fruit juices cerealsoats skimmed milk etc. Avoid sugar oily and spicy foods junk food and other high-calorie diet as these give rise to obesity and are not good for health. For more suggestions consult an expert in this field.
How can I convert videos to a smaller size without losing its quality - online?
Im going to give a short yet probably a very efficient answer here! Don waste your time installing any video editing software. The time it will take you to download it and install it will be much more than the time it will take you to download ffmpeg and do the task in a few seconds. Without quality loss means one those 2 options Full re-encode with a lossless codec (as the name implies it the opposite of lossy (not really the best option) This can be done with pretty much any editing tool as long as you export with lossless codec h264 with cfr = lagarith nI would go for avisynth with any encoder of your choice or Virtual Dub Trim in-place without re-encoding.(faster + best for archiving ) You can simply trim without modifying the codec or wasting time to re-encode the entire video. but there is one problem in this case cutting depends keyframes. You can cut at any second of your choice. If you split with mkvMerge it will split without re-encode and will just round your trim to the closest keyframe. This will give inaccurate result Another way to get around this is by using ffmpeg you can get accurate cut without whole video re-encoding with ffmpeg. It will just re-encode the first few frames and the last few frames (the quality loss will only occur for less than a second of the entire length of your video!)
How do I reduce Zip file size?
Zip is a very old format. It does notpress very well. There are many otherpressors that will produce smaller archives but usually at the cost of more time and more memory usage. If you must use zip format then you can select maximumpression using the -9 option or use a program to produce optimized zip files like kzip. Either waypression will take a lot longer and the savings will be only a few percent. These methods will not slow down dpression. Zippresses each file separately. If you pack related files together in an upressed format first (e.g. with tar) then you might get betterpression. However zip uses a very small window (only 32 KB) so this technique won't work for large files or if the files are more than 32 KB apart in the tar file. Betterpressors like 7zip rar and zpaq use window sizes in the tens of MB and have a solid mode which does this packing for you.
How can I reduce the file size of a 70mb MP4 video to less than 25mb?
You did not mention any relevant information about the video itself. The size tells us nearly nothing about the content. Is it just a second or two of extremely high definition video in upressed format? Or is it hours long at lowish resolution and highlypressed? Depending on the exact specifics your request can vary between a very simple easy to do task through to something which ispletely impossible. Things you need to DEFINITELY state before you can even start asking this question Length of the video in time not size. Resolution. I.e. how many pixels there are in each frame. E.g. is it 18p HD quality half HD 72p 4K DVD 48p something else? Is the file already usingpression? If so which and at what settings? Other things you should also mention Are you willing to loose some quality? If so how much? If you cannot state anything about this then there would be no hope for anyone to even guess if your request is even possible. Never mind telling you what to do. The best I can do is to state what possible choices you can make to reduce a video file size. This may (or it may not) make it possible to get to your requirements. Generally speaking there are only 3 things you can do. All 3 would require some program cable of editing and re-encoding the video. Cut unneeded parts from the video. I.e. if you only want to keep the first 2 minutes of an hour long video then use a video editing program to select and crop only the part you want. Use a betterpression codec or change its settings to throw away more quality of the video. ordered-list Anybination of the above can also be used. Most video encoders allow you to select various options for points 2 & 3 above. Most video editors can do all three.
How can we reduce the size of a torrent file?
Reduction of file size reduces the file quality to a larger extent. We can't differentiate much on the qualities on our mobile or portable screens but the difference is visible on larger screens. Even the audio is diminished whilepression. If you want to look at all the available qualities on torrent then I rmend you to look at pirates bay. Use proxy while searching.
How do I reduce file size of my mobile game?
If you're using .wav files then convert them to .mp3 . Note that the size of the development project doesn't have anything to do with the size of an apk file or ipa file. I think my game's project size was something like 3mb the apk file was 15mb and my ipa file was for the same game. My apk file used to very large but I cut it by half just by simply replacing all .wav s with .mp3 s. I guess the size of your game is fine unless its over 3 mbs.
How can I reduce a one week video to a file size as small as possible?
If it is a static video one of the best things you can do is to record your video with a very long GOP length. A GOP in a video stream consists of a single I frame (one containing the full picture) and many different difference frames which primarily encode how the picture is changing. Difference frames are far smaller than I frames. For static video having too many I frames is largely pointless. If you can set your video encoder to have an open GOP then the encoder can best decide when to put in I-frames. In H264 and related protocols also make sure you turn on the option to have B-Frames. These are also difference frames but they are even smaller than regular difference frames (called P frames). For dash cams your best option honestly is to go to 72p video. Since your application is primarily storage a sharp 72p can consume far less band than a thoroughlypressed 18p video and actually look much better as well. I would rmend you try an experiment with both resolutions. HEVC and VP9 are both the state of the art as far as encoding efficiency go but are limited in where the video can be viewed. They will be about 25% more efficient than H264 on an average but it really depends upon the quality of the encoder. Finally (and for full disclosure I am with apany that builds such technology) use a bitstream optimizer. These are post-encode solutions that can reduce the size of video. These can be particularly thates out of cheap low-end encoders and noisy cameras some of them can get you 235% further reduction. Other things you can do is to try to reduce noise in your video when you capture it. For example keep your scene well-lit for a static camera in the dark the sensor noise can cause too much band to be consumed by useless information. Also mount your dash cam using things that minimize vibration from reaching the camera and help in stabilizing the image. These kinds of thing can have a surprising amount of impact on the bitrate required by your video.
