File Size Limits for Converting Large mp4 Files

Due to the intensive nature of video conversion and processing, there is a limit on the size of the video file. Long videos are fine, so long as their file size does not get too high. There is no limit programmed into the tool but if you are trying to convert a 600mb video to an mp3, the process is going to run out of memory and display an error.

To ensure, you do not have problems, make sure the video file size is not incredibly large. If the video keeps failing to convert with an error about an invalid audio stream, check the log. There will more than likely be an error message saying the script has run out of memory trying to convert the video to an audio file.

Converting music videos to mp3

The main use case for this tool is to try and convert a music video to an mp3 file. This generally means a shorter, 3-5 minute video that will have a relatively small file size. If you do not want the video anymore and want to split the audio and video from each other and just keep the video, this tool will allow you to do this very easily.

You will need to have the video file on your device to do this. Taking the video from YouTube or any other website is not possible using this tool. You must download the video first. Since these videos are already the correct format, it will be easy to convert mp4 to mp3 without any troubles. Just make sure the video isn’t a 10 hour version 😀

Can other video formats be converted to mp3?

This tool is explicitly designed to convert any video that is the mp4 format, but there is no restriction in the code. You can attempt to upload any video and it will try to perform the conversion but it may not work for you. An error message will be shown to let you know whether the conversion has completed successfully or not.

Can I convert the video to different audio formats?

Yes, there are 5 different audio formats supported by this tool. Use the drop-down box to select which video file you want to use. If you are selecting mp3, ogg or another lossy format, you can set the bitrate using the box and it will give you some control over the size of the file that is generated.
