NotEnoughEncodes is a small GUI Handler for aomenc (AV1).

NotEnoughEncodes is a tool to make encoding easier and faster for the AV1 reference encoder.

It splits the Source Video into multiple chunks and encode them parallel with the same given settings. At the end it will Concatenate the chunks into a single video (no audio!).

This tool is Windows only. For multiplatform and more features check out the CLI Tool Av1an.

---

Installation:

1. Download ffmpeg and ffprobe, aomenc and NotEnoughEncodes. (For Windows 7: NotEnoughEncodes)
2. Create a new Folder and put all .exe files in them (ffmpeg, ffprobe, aomenc and NotEnoughEncodes.exe)

System Requirements:

• Microsoft .NET Framework 4.7.2
• Microsoft Visual C++ Redistributable x64

Usage:

1. Open NotEnoughEncodes.exe
2. Select your video file / Set video output file
3. Select the Chunk length in seconds. (The Chunks won't be exactly this long. ffmpeg will cut it at the nearest Key-Frame!)
4. Edit the Encoding settings. (You can save the settings by clicking on "Save Settings")
5. Click on "Start Encode".

NEE has a resume feature, with which you can resume cancled encodes. (unfinished chunks will be overwritten!)

If you press on cancel, the program will terminate ALL aomenc and ffmpeg processes. Don't press it if you have other encodes/instances running!

If you experience framelosses you may have a slightly corrupted video. Using the option "Reencode Lossless" might help with this issue. (Video will be encoded to utvideo - this may take alot of disk space)

---

How does this program work?:

This programm will split the given video file into roughly equally chunks. This splitting process is not reencoding the video. After splitting it will encode the chunks with x amount of workers. When finished, it will mux the encoded files together in one .mkv file. You have to add Audio seperatly.

Disclaimer:

• This is my first Project. I don't really know much about programming and github.

notenoughencodes's Issues

Muxing of Audio and Video failes if using "resume"

If an encoding operation is resumed after interruption, the muxing of audio and video does not work.
You can only mux the resulting files no_audio.mkv (video) and audio0.mkv (audio in folder AudioEncoded) by hand, e.g. with ffmpeg or mkvtoolnix.

ffmpeg hangs on muxing

In v1.6 ffmpeg hangs on muxing due to an extra newline character at the end of 'myfiles.txt'. Or at least, I assume that's the reason based on my limited ability to debug and reproduce the issue on my system.

Crash on resume / resume enhancement.

I encountered a crash-on-resume issue. It is related to

NotEnoughEncodes/NotEnoughEncodes/MainWindow.xaml.cs

Line 623 in 865d091

foreach (string line in File.ReadLines("encoded.txt"))

To recreate the issue:

1. Begin a new encode
2. Cancel the encode before the first chunk(s) finish encoding.
3. Try to resume

The crash is caused because encoded.txt does not get created until after a chunk finishes both passes (I was using 2 pass, but even in one pass, if a job gets canceled before the first chunk finishes being encoded, then it will not create encoded.txt and the user would end up needing to sit through the entire chunking process again, unless they manually create a blank encoded.txt)

---

Enhancements:

1. When encoded.txt is missing, provide the user some way to say "the chunks are all there, just start trying to encode."
2. Write to encoded.txt when, in multi-pass mode, pass 1 completes. In this way, pass 1 does not need to be redone when it was already completed before resume was attempted. Assume any pass-1 log files NOT mentioned in encoded.txt are junk and should be overwritten.

Please and thank you.

Muxing of Audio and Video failes if using "resume"

Hello Alkl58!

Unfortunately there is another problem now. The muxing is now completed, but only the first video chunk (2 s) and the entire audio file are muxed. This creates a file with 2 sec video and 60 sec audio!

Lower FPS option doesn't work

Hello,

I want to be able to encode files into AV1 with lower frame rates, like 12 FPS. I tried 12000/1000 in the settings but it only made the video slower, without throwing out frames, audio cut off halfway.

Is there any possiblity to do it? I'd like to throw out information or blend frames together, if possible.

File concatenation

A few times now, the encode completed without issue, however file chunk concatenation did not occur with muxing of sound. I had to use ffmpeg to concatenate the files manually then add audio.
