Download ((NEW)) File Video1 (4).mp4

I'm trying to concatenate two mp4 files using ffmpeg. I need this to be an automatic process hence why I chose ffmpeg. I'm converting the two files into .ts files and then concatenating them and then trying to encode that concatenated .ts file. The files are h264 and aac encoded and I'm hoping to keep the quality the same or as close to original as possible.

Download File video1 (4).mp4

For .mp4 files (which I obtained from a 50 minute tv episode, downloadable only in three parts, as three .mp4 video files) the following was an effective solution for Windows 7, and does NOT involve re-encoding the files.

The batch file, and ffmpeg.exe, must both be put in the same folder as the .mp4 files to be joined. Then run the batch file. It will typically take less than ten seconds to run..

If what you were looking for is a method for specifying all the mp4 files in the current folder without a lot of retyping, try this in your Windows batch file instead (MUST include the option -safe 0):

Using some python code to do it with as many mp4 there are in a folder (install python from, copy and paste and save this code into a file called and run it from the cmd opened in the folder with python and all the mp4 in the folder will be concatenated) is because "ffmpeg does not support PCM (pcm_alaw, pcm_s16le, etc) in the MP4 container." See here: codec not currently supported in container and here. So, run time ffmpeg -f concat -safe 0 -i inputs.txt -c:v copy -c:a aac output.mp4 instead, to re-encode the audio into AAC format. Or, run time ffmpeg -f concat -safe 0 -i inputs.txt -c copy output.mkv to write into a .mkv container instead of into a .mp4 container.

For those who need to concatenate a number of MP4 videos encoded with H.264, I propose a Python script that automates the Concat protocol/using intermediate files paragraph from the ffmpeg documentation.

Here's my method for joining a directory full of MP4 files using command substitution and the concat video filter (this will re-encode) - figured someone else will get some use out of this one-liner, especially if you have many files (I just joined 17 files in one fell swoop):

If you prefer method #2 from rogerdpack's answer but you don't want to use pipe (e.g. you just want to use execv in C) or don't want to create extra files (list.txt), then just combine concat demuxer with data and file protocols, i.e. FFmpeg allows you to inline input files almost as in HTML:

Before you upgrade to macOS Catalina or later, you can use iMovie to detect and convert all incompatible media files so they'll be compatible with future versions of macOS. After you upgrade, the option to convert the incompatible files will no longer be available.

To convert incompatible media files immediately, click Convert in the window. iMovie creates copies of the media files in the H.264 format. The original files are moved to an iMovie Incompatible Media folder, located in the same folder as the library. Your original media is not modified.

Examples of media that will be affected by the transition to 64-bit technology include video files from early Flip Video cameras that use the 3ivx codec, early web videos encoded with the Sorenson codec, and media converted from DVD to the DivX format.

To convert an incompatible media file, open it with QuickTime Player (version 10.0 and later) in macOS Mojave or earlier, then save a copy with a new name. This method isn't supported in macOS Catalina.

You can also use Compressor to transcode one or more media files into a format such as H.264, HEVC, or Apple ProRes. These formats will be supported in versions of macOS after macOS Mojave. H.264 and HEVC preserve image quality with the smallest file size. ProRes preserves the best image quality and provides better performance when editing in iMovie, but creates much larger files that use more storage space than H.264 and HEVC files use.

If you are playing around with the HTML5 Video tag you might need some sample video files and these video files have to be in different web formats. The problem is that different browsers support different types of video files, so to provide proper cross-browser support, you need to convert your video into many different formats. I plan on writing more about HTML5 Video and some cool things that it allows you to do but as a start, I wanted to convert one small video file into a lot of different formats and provide these files as a sample video for anyone to use in their tests and projects.For web browsers, you are basically going to need MP4, WebM and Ogg formats(Ogg format is specified as type=video/ogg but the video extension is .ogv) while mobile browsers will use MP4 and 3GP formats. And HTML5 is obviously about eliminating the need for Flash but I will include flv format as well. The original mp4 is really small, just 385Kb and the video lasts 5 seconds. Feel free to use the following files for whatever you need:

After Effects is feature-packed to allow you to create literally anything you can imagine in your video projects. Unfortunately, it also produces gargantuan video file sizes that are nearly impossible to share.

Open the installation file and install the program following the on-screen instructions. Movavi Video Converter has a simple and intuitive interface, so you can easily use this software for the conversion of MP4 and other video processing needs!

Click Add Media in the upper-left corner of the screen and select Add Video. Now choose the MP4 video that you want to convert to AVI. Movavi Video Converter supports the batch conversion of MP4 as well as other formats, so you can convert multiple files or even an entire folder in one pass!

This is a desktop MP4-to-AVI video converter for Windows and Mac. The software enables you to convert and compress video files in a short time. It supports batch conversion, so you can convert multiple files at one time. Apart from converting, the program offers some editing options, including trimming and splitting, applying filters, and adding a watermark. The free version of Prism Video Converter is available for non-commercial use only.

This is another online MP4-to-AVI converter that can help you change the format of your videos to AVI. Online-Convert lets you adjust audio and video settings before you start the conversion. You can change the width and height of your video, the bitrate, and the frame rate. Other options include cutting, rotating, and flipping your video. The converter enables you to change the audio quality as well. Keep in mind that you can only convert files up to 100 MB for free. If you have large files to convert, choose one of the plans for a paid subscription. With paid plans, the conversion speed will also be higher than in the free version.

Converting MP4 to AVI with Convertio is quite easy. You simply need to upload your files, choose AVI as the target format, and start the conversion process. You can adjust additional settings if needed. For example, you can change video resolution and audio bitrate, rotate or flip your video, increase or decrease the volume. So, if your file is not larger than 100 MB, you can use Convertio to convert MP4 to AVI online for free; unlimited conversions, however, are available only with a paid plan.

On the ConvertFiles main page, click Browse and select the video you wish to convert. Open the list of formats next to Output Format and choose Audio Video Interleave File (.avi). Hit the Convert button and wait until your file is converted. After that, follow the link for downloading your file and click Download Free.

If you simply want to convert a small file, the best option is to use one of the free programs mentioned in the review. You can choose between desktop and online tools. Free converters, however, usually have different limitations, like relatively low conversion speed, limited file size, or inability to convert multiple files at one time. To convert files without such limitations, you can use a paid alternative, like Movavi Video Converter. It offers ultrafast batch conversion and many editing features.
