<h3>Transcode to H.264</h3>
|
||||||
|
<p><code>ffmpeg -i <i>input_file</i> -c:v <i>libx264</i> -c:a copy <i>output_file</i></code></p>
|
||||||
|
<p>This command takes an input file and transcodes it to H.264 with an .mp4 wrapper, keeping the audio the same codec as the original. The libx264 codec defaults to a “medium” preset for compression quality and a CRF of 23. CRF stands for constant rate factor and determines the quality and file size of the resulting H.264 video. A low CRF means high quality and large file size; a high CRF means the opposite.</p>
|
||||||

<dt>ffmpeg</dt><dd>starts the command</dd>
|
||||||
|
<dt>-i <i>input_file</i></dt><dd>path, name and extension of the input file</dd>
|
||||||
|
<dt>-c:v libx264</dt><dd>tells ffmpeg to change the video codec of the file to H.264</dd>

<dt><i>output_file</i></dt><dd>path, name and extension of the output file</dd>
|
||||||
|
</dl>
|
||||||
|
<p>In order to use the same basic command to make a higher quality file, you can add some of these presets:</p>
|
||||||
|
<p><code>ffmpeg -i <i>input_file</i> -c:v libx264 -preset veryslow -crf 18 -c:a copy <i>output_file</i></code></p>
|
||||||
|
<dl>
|
||||||
|
<dt>-preset <i>veryslow</i></dt><dd>This option tells ffmpeg to use the slowest preset possible for the best compression quality.</dd>
|
||||||
|
<dt>-crf <i>18</i></dt><dd>Specifying a lower CRF will make a larger file with better visual quality. 18 is often considered a “visually lossless” compression.</dd>
|
||||||
|
</dl>
|
||||||
|
<p>libx264 will use a chroma subsampling scheme that is the closest match to that of the input. This can result in YUV 4:2:0, 4:2:2, or 4:4:4 chroma subsampling. QuickTime and most other non-FFmpeg based players can’t decode H.264 files that are not 4:2:0. In order to allow the video to play in all players, you can specify 4:2:0 chroma subsampling:</p>
|
||||||
|
<p><code>ffmpeg -i <i>input_file</i> -c:v libx264 -pix_fmt yuv420p -preset veryslow -crf 18 -c:a copy <i>output_file</i></code></p>
|
||||||
|
<dl>
|
||||||
|
<dt>-pix_fmt <i>yuv420p</i></dt><dd>Specifies a pixel format of YUV 4:2:0 to allow the file to play in a standard QuickTime player.</dd>

<p><code>ffmpeg -f concat -i mylist.txt -c copy <i>output_file</i></code></p>
|

||||||
<p>This command takes two or more files of the same file type and joins them together to make a single file. All that the program needs is a text file with a list specifying the files that should be joined. However, it only works properly if the files to be combined have the exact same codec and technical specifications. Be careful, ffmpeg may appear to have successfully joined two video files with different codecs, but may only bring over the audio from the second file or have other weird behaviors. Don’t use this command for joining files with different codecs and technical specs and always preview your resulting video file!</p>

||||||
<p><code>ffmpeg -i <i>input_file</i> -c:v <i>libx264</i> -c:a copy <i>output_file</i></code></p>
|
|
||||||
<p>This command takes an input file and transcodes it to H.264 with an .mp4 wrapper, keeping the audio the same codec as the original. The libx264 codec defaults to a “medium” preset for compression quality and a CRF of 23. CRF stands for constant rate factor and determines the quality and file size of the resulting H.264 video. A low CRF means high quality and large file size; a high CRF means the opposite.</p>

</dl>
|
|
||||||
<p>In order to use the same basic command to make a higher quality file, you can add some of these presets:</p>
|
|
||||||
<p><code>ffmpeg -i <i>input_file</i> -c:v libx264 -preset veryslow -crf 18 -c:a copy <i>output_file</i></code></p>
|
|
||||||
<dl>
|
|
||||||
<dt>-preset <i>veryslow</i></dt><dd>This option tells ffmpeg to use the slowest preset possible for the best compression quality.</dd>
|
|
||||||
<dt>-crf <i>18</i></dt><dd>Specifying a lower CRF will make a larger file with better visual quality. 18 is often considered a “visually lossless” compression.</dd>
|
|
||||||
</dl>
|
|
||||||
<p>libx264 will use a chroma subsampling scheme that is the closest match to that of the input. This can result in YUV 4:2:0, 4:2:2, or 4:4:4 chroma subsampling. QuickTime and most other non-FFmpeg based players can’t decode H.264 files that are not 4:2:0. In order to allow the video to play in all players, you can specify 4:2:0 chroma subsampling:</p>
|
|
||||||
<p><code>ffmpeg -i <i>input_file</i> -c:v libx264 -pix_fmt yuv420p -preset veryslow -crf 18 -c:a copy <i>output_file</i></code></p>
|

<dt>-filter:v</dt><dd>calls an option to apply filtering to the video stream. yadif deinterlaces. scale and pad do the math! resizes the video frame then pads the area around the 4:3 aspect to complete 16:9. flags=lanczos uses the Lanczos scaling algorithm which is slower but better than the default bilinear. Finally, format specifies a pixel format of YUV 4:2:0. The very same scaling filter also downscales a bigger image size into HD.</dd>

<p><code>ffmpeg -f concat -i mylist.txt -c copy <i>output_file</i></code></p>
|

|
<p>This command takes two or more files of the same file type and joins them together to make a single file. All that the program needs is a text file with a list specifying the files that should be joined. However, it only works properly if the files to be combined have the exact same codec and technical specifications. Be careful, ffmpeg may appear to have successfully joined two video files with different codecs, but may only bring over the audio from the second file or have other weird behaviors. Don’t use this command for joining files with different codecs and technical specs and always preview your resulting video file!</p>

This must match the naming convention actually used! The regex %06d matches six digits long numbers, possibly with leading zeroes. This allows to read in ascending order, one image after the other, the full sequence inside one folder. The extension for TIFF files is .tif or maybe .tiff; the extension for DPX files is .dpx (or eventually .cin for old files).<br/>
|
||||||
|
The showing speed depends on the image’s file size and on the computing power. It is usually to slow, yet you can visualise immediately the moving images without having to recode and remux into a new file.<br/>

<p>This will losslessly trancode your video with the FFV1 Version 3 codec in a Matroska container. In order to verify losslessness, a framemd5 of the source video is also generated. For more information on FFV1 encoding, <a href="https://trac.ffmpeg.org/wiki/Encode/FFV1" target="_blank">try the ffmpeg wiki.</a> </p>

This must match the naming convention actually used! The regex %06d matches six digits long numbers, possibly with leading zeroes. This allows to read in ascending order, one image after the other, the full sequence inside one folder. The extension for TIFF files is .tif or maybe .tiff; the extension for DPX files is .dpx (or eventually .cin for old files).<br/>

The showing speed depends on the image’s file size and on the computing power. It is usually to slow, yet you can visualise immediately the moving images without having to recode and remux into a new file.<br/>
