How to Upload a Video in Blender

Blender convert a sequence of images into mp4 video

In this tutorial for Blender (updated to Blender 2.8x) nosotros will show you how to convert a sequence of images into an mp4 video for Youtube using the Video Sequence Editor (VSE).
When rendering an animation with Blender it is advisable not to save information technology immediately as a film, only as a sequence of images (in PNG format, as information technology is the one with the best quality / compression ratio and is compatible with many softwares) and in society to resume rendering from a certain frame onwards in the event of a crash, both in society to separate a rendering into several parts, to exist carried out comfortably in the most user-friendly moments.
However, there is a need to export the video in other formats to evidence it to the public (in a youtube video, on a web folio or even simply to view them with a player) or to compress all the animation in a single file of size smaller and more than compact.

Upload the epitome sequence:

To transform the sequence of images, nosotros will use the Video Sequence Editor (VSE), one of the many precious tools contained in Blender, which has many features in common with the best professional video editors.

In the tiptop menu we select the "Video Editing" workspace or, if it is non present, we add it by pressing the "+" push button on the right

and we volition display the editor with the list of directories, the preview of the video, the Properties Window, the channels of the Video Sequencer and the panel with the properties of the currently selected instrument

When we render an animation, the files will be inserted in the directory whose path is indicated in the "Output Properties" tab, in the Backdrop Window at the top correct, in the "Output" subpanel.

We add the sequence of images by selecting, in the menu to a higher place the channels of the Video Sequencer, Add > Paradigm/Sequence

then the popup window will open up to import the files and we select the directories whose path we had noted before in the properties

Nosotros now select the images to exist imported, we have different modes available:

• Selecting all the images past pressing the A key (a useful method, which tin exist implemented without problems if in the directory there are merely the files we desire to upload)

  

• Using the rectangle choice tool, activated by pressing the "B" central, we tin select only the files that interest the states

• Selecting part of the images with the keyboard: click on the first file and, belongings down the SHIFT key, click on the final

  

On the correct are the import options, nosotros exit the default options unchanged: Start Frame:1, End Frame:26, Aqueduct:ii and immediately press the bottom button "Add together Image Strip".

In this example we have loaded a number of frames and then that information technology is equal to the value of "Stop Frame" (26); if information technology had been smaller, a filling surface area on the right of size = Cease Frame - number of loaded frames would have been created.
The Frame Charge per unit is set to 24 frames per second, so the sequence of 26 images is longer than 1+00, that is longer than a second, too nosotros can see that it has been positioned in aqueduct number 2. The Start Frame value indicates the position where the frames will be placed in the channel.

Convert the image sequence to an mp4 video file for Youtube with Blender in the Video Sequence Editor:

Once the sequence of images has been imported, we try to catechumen it into a single mp4 file, which can eventually be uploaded to Youtube. We therefore use the Properties Window options that we can find in the panel at the tiptop right.

We select the "Output Properties" tab and in the "Dimensions" subpanel we set the dimensions that the movie must take; these may correspond to the dimensions of the images in the sequence, or to the dimensions of the movie we want to create (for case, if we want to consign the flick to upload it to Youtube, a good resolution could be 1920x1080). Nosotros likewise prepare the duration or portion of the animation in frames and the frames per second of the animation (24 or 25 frames per second should be fine for common viewing, just for movies where you want to salve y'all can get up to 15 fps, while for movies with fast animations you can set 60 fps)

In the "Output" sub-panel nosotros open up the "File Format" drop-down bill of fare and we meet that at that place are various formats, both image and video; select "FFmpeg video" which will provide us with the features offered past the FFmpeg video conversion software (if you want to employ it in standalone mode for other purposes, you can download it from https://world wide web.ffmpeg.org/, but in our case information technology is already included in Blender)

All the formats supported by FFmpeg regarding the container appear, the video codec and the audio codec

If we open the Encoding > Container drop-down menu nosotros can come across the list of containers fabricated available by FFmpeg

for each container we choose, a dissimilar list of "Video Codec" or unlike options associated with the unmarried container will appear, in cases where at that place is a i:i correspondence between the codec and the container.
For case, if we cull MP4 as a container, we can choose between these codecs

and related codecs (AAC is recommended for Youtube) for a possible audio file,

which tin exist loaded and placed in another channel by selecting the Add together > Audio command in the VSE card

Close to the discussion "Encoding" yous can click on a button that allows the selection of some presets, useful for speeding upwardly some operations. For example, if we desire to upload the video file to Youtube, we can choose a format with MP4 container and H.264 video codec, then just select "h264 in MP4"

Returning to look at the other video options:

"Output Quality" indicates the quality that the film must have, we recommend the "Medium quality" value for the tests and "High quality" for the last version. If you don't want to lose any detail you can choose "Lossless" (without loss of data, but the file later on will be much larger).

"Encoding Speed" indicates the encoding speed: greater coding accuracy will take longer, but the encoded file volition be smaller.
One time the settings for exporting the video have been completed, we bank check that the "Sequencer" option is checked in the "Post Processing" sub-panel,

and then to first coding we printing CTRL+F12 or select in the menu Render > Render Animation, as when nosotros start rendering the animation,

and, when finished, a new file will be created in the output directory whose name will have into account the imported frames and the called format, for example "0001-0026.mp4".

Here ends the tutorial for Blender to convert a sequence of images to mp4 video, so you can bear witness your fantastic animations made with Blender on Youtube, the procedure is fast enough, just you take to pay attention to the codecs, perhaps installing free packages similar G-Lite (Windows) and good players like VLC Media Player. Happy blending!
