![]() ![]() In addition to converting, you can also trim, combine, crop, and resize your videos, as well as add music, text, animations, and transitions to them. These file formats will be converted to mp4 for ease of use and transfer. You'll see these conversions happen in real time for files like FLVs, WAVs, WMVs, AVIs, and more. Uploading various file types that are not natively playable in the browser will trigger a conversion on upload. ![]() Video file types like FLV, WEBM, and AVI don't always play correctly on all devices, and with Kapwing these files can be easily converted to a more widely accessible container format like MP4. When sharing your content, you want to make sure your files are in a format that is universally accepted and reliable. Press the 'Start' button to begin converting your MP4 to MP3 audio. Click the 'Audio Codec' tab and select 'MP3' from the 'Codec' drop down box. Click the 'Convert' button at the bottom of the screen. Once you have made your selection, simply press the Export button at the bottom to create your newly converted video. Locate the MP4 on your hard drive you want to convert. ![]() The options are MP3 for saving the audio from videos with music, JPEG for saving a specific screenshot image from the video, GIF for short animated images clipped from the video, and MP4 for converting MOV, FLV, AVI, and other video files, or saving videos from the web straight to your files. Click Edit > Preferences > Files > Import Settings > MP3 Encoder in the Import Using section. Then, a new sidebar will pop out that will list your export options. There is little wonder, therefore, that you won't notice the subtle differences between the MP3 and AAC audio files.When your video is uploaded to Kapwing, you can make any edits to your video, or you can go straight to conversion by clicking Export Project on the right sidebar. Some AAC encoders may not leverage all of AAC's additional encoding tools. As you use your encoder, watch out for the encoding speed, which ultimately influences how your track sounds. When it comes to the accuracy of transient signals, AAC has the upper hand with the 128 samples block size compared to MP3's 192 sample size.ĭo you want to correct the design choices on original MP3 files? The AAC format lets you create audio files with your preferred specifications. AAC uses 940 or 1024 samples, further enhancing the encoding. MP3's block size of 576 samples further reduces the coding efficiency. The MP3 format, on the other hand, uses a hybrid coding system that comprises the overall encoding process. With a pure MDCT, AAC boasts of higher encoding efficiency. You'll also have an easier time working with surround sound mixes. ![]() This specification lets you compress multichannel audio on AAC with less hassle. MP3 files can only store two channels of synchronous audio compared to AAC's 48 channels. With this flexibility, you can simultaneously use multiple encoding strategies and compress your files more efficiently. While MP3 files at this encoding rate tend to sound a bit muddy and distorted, the AAC files have stood up more as the file size decreases.ĭevelopers have greater flexibility in the AAC format than MP3 when designing codecs. Though this is not such an issue with devices these days, it makes all the difference for things like audio streaming.Īt 128 Kbps we think the biggest sound difference is in the AAC. However, the MP3 file is so much smaller that it could be preferable for those who need to save space. The files are slightly bigger, but there is a bit of an increase in quality with the AAC files.Īt 256 Kbps, the difference in the files is quite hard to notice, they are virtually indistinguishable when it comes to quality, and the MP3 does a fine job of carrying quality audio.Īt 192 Kbps we would say there is a slight difference in quality. As you can see, the MP3 files are slightly smaller in each of the different encoding rates. An example of a test of the file sizes, comparing the size of MP3 versus AAC files at the same encoding rate. ![]()
