The rendered video is too big!

[Vini310]

So, I just finished the video I had to make for the class, but, after the renderization ended, I looked at the file size and realized it was way too big (21 GB)! How did this happened? It can't be the length, because the video is 2 minutes long.

Just to clarify, I used Blender's video editor to make the video.

It depends largely on the encoding format you've chosen. If you chose AVI RAW then none of the frames were compressed. Oh, and the resolution, and PS, of course.

You could transcoding in either Blender (new .blend, import your video, set output settings correctly, choose a good encoding format that supports good encoding) or using a tool like ffmpeg on the command-line. The internet should give you lots of options for transcoding.

I've had 10 second GIFs come out of a render from an image editing program that are much larger than 21 GBs.
Length, Resolution, FPS, Quality, Format all play a major role in what the file size will be.

A MP4 at 4K with a FPS of 60 on lossless is going to be way bigger than the same render of a MP4 at 1080p with a FPS of 24 on high quality.

The size would most likely be different again for both renders if you used AVI or MVK instead of MP4.

I used AVI Raw...

and there you go, AVI with no compression... The file is going to be massive.

(Whoa, Blender Release Team, welcome to the party!! Have I got questions for you!!!
LOL)

But, other than AVI Raw, the only video rendering options Blender have are AVI JPEG and FFMpeg, and that's weird because one of the clips I used in the final video was crated by my friend, who managed to make it a MKV format. How exactly he did that?

[Pte Jack]

Select FFMpeg, that is where you're going to find most of the other container formats available. (MP4, MKV, Ogg, DV, Compressed AVI, etc).

Blender uses the containers from FFMpeg (which I believe is embedded in Blender) for rendering.

Once selected an encoding panel will be available, expand the Encoding panel then use the Container Drop down (which I believe is defaulted to MKV) to select the container you want to use.

Just to follow up on the above, Once you have the container you want to use selected, you move on to the Video panel and set up the quality you want to produce. If you have audio and want to include it in your video, you have to click audio on, then set that up as well (format that works with the container you chose and the bit rate, etc). Don't forget to import the audio clip in the video editor if the audio is not already part of your animation and to set the Audio/Video Sync if needed.

This is a little cheat sheet I created for rendering animations from Blender (2.8x)

I selected FFMpeg and rendered a new version, this time it's in MKV and is much smaller. So, it worked better than I expected.

I just wish I knew about the AVI Raw thing earlier, because guess how I rendered EACH INDIVIDUAL CLIP that was used in the video?

If and when you import other videos or live footage make sure the FPS matches your project. You may have to re-encode to the target FPS you want to work with.

Just create a new .blend file, import your video as a movie strip, set the settings otherwise as you need them and then render that out as your animation. You're effectively transcoding using Blender as the GUI to FFMPeg

I pretty much did that. The video was already ready, so I just rendered a new version in a different format.
Both videos are exactly the same content-wise.

Yup, you are correct and the FPS rate is covered up by one of my inserts, but this is rendering animations directly from Blender.

Imported image sequences and video (plus audio) would use this one.

A note I added to this guide because every time I sat down to do a new video for 2.8x, something would change. Now that 2.83 has gone LTS, I just might make a new guide, but waiting to see if 2.9 is going to change things yet again. (One of the many questions I want to ask, but afraid of the answers I might get. LOL)

Underneath where you select FFMpeg, there is a menu section for encoding.

I usually switch the "Container" dropdown to MP4 when I render videos.
