![]() The total bitrate (and file size) is simply the combined audio & video bitrates. Usually, an audio/video file isn't significantly bigger even if you use uncompressed audio (depending on the video format/bitrate and the audio resolution, etc.) Video bitrates are often expressed in Mbps, and again you can calculate the file size by dividing by 8. Even if ffmpeg can read the container format, it may not support all its codecs. 1.3 I cannot read this file although this format seems to be supported by ffmpeg. A DLL loader is not conducive to that goal. Moreover FFmpeg strives to support all codecs natively. The Video usually takes-up more space than the audio. Windows DLLs are not portable, bloated and often slow. Of course, 224kbps MP3 is the same size as a 224kbps MP4. You already know there are 60 seconds in a minute, so it's not hard to calculate the file size from the bitrate & playing time. kbps is kilo bits per second, and if you know there are 8 bits in a byte you can divide by 8 to get the kilo bytes per second. Once you have downloaded and unzipped LAME, open Ots Studio and. ![]() The space/file size is determined by the bitrate (kbps). Please note that using MP3 encoding technology in some countries without. MP3 isn't necessarily smaller than MP4 ( AAC) or any other compressed format. and keeping a decent enough video quality. An example of a command for encoding could. ![]() so its ok.įor my tutorial purpose i am only interested in reducing the file size as much as possible. You can use the copy codec to perform operations on a file without changing the encoding. Quote Actually i am more concerned with the file size on my disc and the time it takes to upload the video. Because I have an iPhone and iPad, I use iTunes. I should have stated my problem more simply instead of providing so much incorrect background information so here goes my second try. Eventually after some difficulties locating and installing the encoders I landed here. I thought that Lame was a codec that included FFMPEG and that by installing it I would be able to do what I’m trying to do. After some search it seemed to me the LAME MP3 is best for reducing size while also maintaing good quality. and the size of the videos i record are huge and at some point things started to blow out of proportion, thats when somebody suggested me using camstudio and looking for good encoders. With this you can export using the installed LAME MP3 encoder or FFmpeg encoder. much appreciated.Īctually i make tutorials for youtube and my videos are usually pretty long around around 1 hour. An easy-to-use script and application package for encoding LAME -preset. If its indeed so then my problem is solved now. Sorry I already mentioned i am a noob at such things. Now when I run the program, it says that my video export failed because FFMPEG didnt find the libmp3lame codec that it needs. ffmpeg -i 'blahsample1.mkv' -acodec aac -vcodec copy blahsample1.mp4 Added by barlop. If MPEG Layer 3 appeared right after you've installed k-lite codec pack, and the LAME encoder is included in the pack, don't you think this is the option you're looking for? After all, "MPEG Layer 3" is MP3.Īctually I didnt knew that. ffmpeg -i 'WSC KAT.mkv' -t 10 -acodec copy -vcodec copy blahsample1.mkv To generate a MP4 from the sample.
