Hi everyone,

In this post, I’ll show you how to download ffmpeg to use with SVT-AV1 GUI. FFmpeg is required to extract the video file to .y4m, encode the audio to Opus, and merge both files when the encode is finished.

Here are the steps:

1. Navigate to https://ffmpeg.zeranoe.com/builds/:

Step 1
Step 1

2. Select the nightly build which is the first one shown in “Version”. Select the 64-bit Windows version if you have a 64-bit machine, and select “Static” in the Linking column. Then, click on “Download Build”:

3. Click on the downloaded file:

Hi everyone,

Today, I’m sharing yet another AV1-encoded video using rav1e. As usual, it was encoded with parameters -q 175 -s 0. This video started encoding at 7:29:10 PM yesterday and concluded at 5:01:07 AM today. Enjoy and let me know what do you think of the quality:

I’ve also updated rav1e GUI to include this rav1e build. Download at the rav1e GUI page.

Hi everyone,

Yesterday, I started encoding one video I recorded in 2011. The encode started at 12:39:28 PM yesterday and finished at 9:50:41 AM today. Encode settings where -q 175 -s0 and the audio is encoded using opus at a bitrate of 64kb. The resulting size of this video is just 12.9MB! See it below:

The video was encoded using my tool, rav1e GUI

Hi everyone,

I have released rav1e GUI v1.3:

rav1e GUI v1.3
rav1e GUI v1.3

This new version adds the new min-keyframe argument to the GUI as well as making the existing keyframe be the max keyframe interval. This means you can now specify a number of frames to be the minimum and maximum keyframe interval and rav1e will make keyframes according to these specified numbers. If you’d like to just use a single keyframe interval, you can specify the same number in the minimum and maximum value boxes.

Another change is that you can now save your video using the Matroska container. This is in addition to the WebM container. Lastly, I renamed piece to part in the GUI, which is used to specify the length of each video part when splitting the video to accelerate encoding.

As usual, this release includes the latest version of rav1e as well as the latest version of opusenc.

You can download this new version in GitHub here:
https://github.com/moisesmcardona/rav1e_gui/releases/v1.3

Also, the source code can be found here:

Enjoy!

Hi everyone,

Today, I’ve released a new version of rav1e_gui:

rav1e GUI V1.2
rav1e GUI V1.2

This version adds a piece seconds parameter that you can modify to split the video file into the specified seconds amount part. This gives you greater control on how long should the parts be to encode them to AV1 using rav1e.

You can download this new version here:

Enjoy!

I haven’t made any new encoding test using the latest rav1e versions but I’ll be doing some soon! I’m currently cleaning up my gaming recordings and I’ll be using a clip from those to test these new builds.

As always, enjoy the new release!

Hi everyone,

Yesterday, I released rav1e_gui v1.1. This build adds 2 new options which are related to my contribution toward the rav1e project I talked in this post. The Pull Request got accepted, so every rav1e builds coming forward will have these 2 new options:

  • Keyframe Interval – Allows you to specify a keyframe interval. Before, it was locked to one keyframe per 30 frames, but now the user can choose this interval by using the –keyint or -I flags.
  • Low Latency Mode – Enabled by default. Basically, disabling this enables frame reordering during encoding.

The GUI now adds these 2 new options and also provides another option to keep or remove the temporary files produced during encoding.

Hi everyone,

Yesterday I had my first experience writing code in Rust. I decided to implement 2 command-line options for the rav1e AV1 encoder software that I’ve been playing around for some days.

The encoder currently encodes files with a keyframe every 30 frames. This value is hardcoded into the code and can’t be changed by the user unless it is changed at the code and rav1e is compiled again. Also, there is a new option which is called “Compound mode” in the source code, which can also be enabled or disabled by sending a boolean value of true or false.

To give more power to the user, I added these 2 command-line options:

  • –low_latency, to enable compound mode. Default is false.
  • —keyint, or -I, to specify a value for the keyframe interval. Default is 30.

  • ravi1e Contrubution 1
  • ravi1e Contrubution 2

This is currently waiting approval. You can see this Pull Request here: https://github.com/xiph/rav1e/pull/677
