GUI for AV1 (aomenc, rav1e & svt-av1)

NotEnoughAV1Encodes

NEAV1E is a GUI for AV1 encoders - aomenc, rav1e, svt-av1 & vp9.

A tool to make encoding faster and easier for AV1 encoders.

---

🔬 How does this program work?

1. This program will split the given video file into chunks (scene based splitting or equal chunks).
2. After splitting, it will encode the chunks with n-amount of workers.
3. When finished, it will merge the encoded files to a single video file.

[AOMENC] Encoding speed decreases over time - low CPU useage

Remember those sketchy download sites from years ago that used to slow the download speed over time for files and eventually you couldn't complete the download before the heat death of the universe? That's what's happening.

When I did my first encode it was running at around 20-24 FPS, it slowly crept down to 10, and then 5, and then 1, and I canceled it when it hit 0.24 FPS.

I don't know how else to describe it.

As the FPS goes down so does the CPU usage with it.

If you would like a log or something please respond with how I can get that for you.

Constant Quality bar behavior inverted

The behavior of the bar is inverted, thus choosing high quality will produce low quality and the other way round.
The functionality is given and the encoding working.

Window position resets randomly at restart on HiDPI monitors

No matter where the window ends up at the time of closing, it always defaults to specific positions on the screen when the program restarts.
And the position changes a little randomly on my 120 DPI monitor.

I'm wondering if this helps, but for a reference, StaxRip suffered a similar issue, and it was due to a UI Scale Factor behaving weirdly on a HiDPI screen.

[Feature Request] Track name for audio tracks

I would like to be able to name a audio track, for example when you have a audio track with commentary from the director.
Can you please integrate this in your great program? :-)

Thank you.

Kind regards

Updater not working

I am experiencing a issue with the updater in neav1e v1.3
It displays weird things and does not update / download

Also unrelated issue: The installer version seem to have permission issues on Windows AME, where the user has restricted permissions.

First underscore dropped from input & output filenames

Version 1.3 appears to be dropping the first underscore ("_") character from filenames entered into "Open Source" and "Save To..." filename dialogs. For example, entering 1_2_3_4_5_6_7_8.mp4 results in 12_3_4_5_6_7_8.mp4 being displayed in the the Overview tab.

running out of disk space when using large files

i was trying neav1e and ran into some problems with larger files where the splitting process used way to much disk space

the file i used was a h265 with a resolution of [email protected] in 10 bit and roughly 2 hours of runtime
neav1e tried to split the file into chunks with 864 seconds length which results in 67gb for each chunk

Trim start settings are ignored when using Advanced settings

Time marks in TRIM START and TRIM END are not applied/used when encoding.
See here https://i.imgur.com/kMRGHwd.png

Shows encoding complete but does not output anything if filenames have cyrillic characters.

Trying to encode a file with cyrillic characters in the name (russian, in this case). NEAV1E jumps to the end, and completes encoding, without outputing anything. This might be unicode related, so other foreign languages might face the same issue.

Updater unable to check for new versions

Hello,
the updater is no more working. The "Upate Version" shows no text for a new version.

Program crashes while encoding audio

Copy Audio (FLAC) within Batch Processing

Hello again,

thank you for your latest Update. :-)
Since Version 1.5 I have issues with processing a bunch of mkv files with flac audio inside.
When I tune the settings, set the input and output locations, and then start the encoding, it detects the scenes of the first file and then the gong sound for finished batch immediately plays. Nothing encoded.
Do I have to set the audio bitrate to 0 for audio copy or leave it default (128)? Neither of the options actually work...

The program.log is not very helpful...

Regards

Crash when using Batch / Queue Encode

Issue: The program crashes unexpectedly after starting any Batch / Queue Encode

Possible cause: Might be a result of the change how cancellation is handled recently

[SUGGESTION] Cross-platform command-line AV1 / VP9 / HEVC / H264 / VVC encoding framework with per scene quality encoding

I found this interesting framework that aims to:

Spliting video by scenes for parallel encoding because AV1 encoders are currently not good at multithreading, encoding is limited to single or couple of threads at the same time.

• PySceneDetect used for spliting video by scenes and running multiple encoders.
• Fastest way to encode AV1 without losing quality, as fast as many CPU cores you have :).
• Target Quality mode. Targeting end result reference visual quality. VMAF used as substructure
• Resuming encoding without loss of encoded progress.
• Simple and clean console look.
• Automatic detection of the number of workers the host can handle.
• Building encoding queue with bigger files first, minimizing waiting for the last scene to encode.
• Both video and audio transcoding with FFmpeg.
• Logging of progress of all encoders.

EDIT: dunno if can help/inspire, but I just found a GUI for it -> https://github.com/natis1/qencoder

Hope that helps/inspires !

MKVMerge not merging

Issue: MKVMerge not merging on a clean Windows Install

Possible cause: MKVToolNix has been installed, but it might not set the Path Correctly

Broken Updater

Muxing failed video output not detected

I can give anything needed at a later date

Chunking rounding issue

There's a small issue: When calculating chuck length, it rounds down instead of rounding up. So, it splits into 17 chunks instead of 16 when I select 16 threads.
If I add one second to the chunk length, it makes it 16 chunks.

pyscenedetect causes videos to be incorrectly coded as twice as long

Using pyscenedetect makes the muxed video look like it is almost twice as long as it should be, time wise. Using time chunks or ffmpeg's scene detection doesn't have this problem. It also wasn't VFR related, the problem is only happening when pyscenedetect is used. For example, the video I am encoding is 11m 52s long, but the output file is 23m 44s, even though it cannot seek so far. The actual video is only 11m 52s in the output file, even though ffprobe, mpv and other plays show the output as 23m 44s long.

Checkboxes doesn't mark off

OS: Windows 7

Title describes the issue. Checking off boxes doesn't appear visually, and stay blank.

Running the program with compatibility options doesn't seem to resolve the issue.

[Feature] VVC Support

Something like https://github.com/fraunhoferhhi/vvenc ? It's licensed under BSD.

Encode jobs merge with two instances active

I've had one job finished and started up a separate instance of the program.
After that second one was finished, I opened the result and I saw that it had like 10 seconds of footage from the previous encoding job. Thus the entire encoding had to be done again.

Don't know for sure how to reproduce it but I think you can do it the way that I did.

Edit: This doesn't always happen. Sometimes the program crashes right after splitting the job for the second instance. That is a separate problem which needs to be addressed.

Produces a file with the encoder settings in the description tag because of previously checked box in same instance

it produced a file with the encoder settings in the description tag because I had previously checked that box

[Feature Request] - Target VMAF

Is it possible to add a target VMAF like Av1an has? Would make the whole fiddling with qp more or less obsolete and would be the best way to archive a target quality.

Issue custom temp Path - issue not deleting temp files - issue shutdown after finish.

Hello Alkl58!

I only had three issues while testing your GUI:

1. The Custom Temp Path that I set and save is not saved and is no longer available the next time the program is started. It adjusts itself to the other custom temp path immediately. (see photos)

2. If the custom temp path is set, the temp files are not deleted after the encoding is completed.

3. The shutdown after the encoding process does not work.

(saved custom temp file D:\NEE)

(After restarting the program, the set custom temp path automatically changes to the other custom temp paths! Of course I had the previous settings saved in profile and saved this as the default. )

Otherwise thank you for this awesome GUI !!!

Good work !!!

Best regards!

Installer does not purge old version

Would be probably better to remove it.

The default settings result in too many tiles (2x4).

The file size increased and I tested the number of tiles. (Andvanced settings good 1x1 tiles.)

Splitting strategy suggestion

As I understand it, the ffmpeg method splits on every scene change regardless of how many chunks are required for a given worker count. I believe this is not an optimal way to do it, especially since we can't assume that ffmpeg's scene detection takes the same decisions as AV1's and the threshold is arbitrary. As such we get a lot of extra keyframes, wasting the bitrate and hurting the decisions that codec would have made if it was able to look ahead past the next enforced split.

Instead, why not split the minimum amount of times required for a needed concurrency? So if we set 2 workers, ffmpeg should only look for a scene change around the middle of the video, splitting it into 2 roughly equal chunks, and so on. I've measured SSIM of the equal chunks strategy VS ffmpeg scene detection and there are noticeable quality drops in the latter.

Small number of extra frames added, causing sync issues

I have done several encodes lately (first of all thanks for the excellent program!!) and have noticed that on some of the movies I've done they end up out of sync with the audio, typically more so as time goes on.

I updated to all the latest versions but am still encountering the problem. For example, I am encoding a Blu-Ray x264 rip of a movie - the original movie has a total of 124480 frames (duration 1:26:31) but the AV1 encoded movie has a total of 124486 frames (duration 1:26:32). So somehow 6 frames are being added, causing the video to be slightly behind the audio the further into the movie you go.

I've attached screenshots of the original and encoded, both after navigating to frame 100000 in MPC-HC.

If it matters, I've used the default ffmpeg scene detect, typically do a resize down to 720p, and use the settings in the attached image.

It's driving me crazy, any idea what the issue is or if I'm doing something wrong?

neav1e encoding modern video for web issues

Hi @Alkl58 and thanks for nice an really good look encoder.
I meet nav1e (and put #100 star :-) ) from v1.4 when i was find an svt-av1 windows GUI because HandBrake cant encode AV1 and other tools not using mutlithreat mode.

My target: encoding video for upload its to my website and i want to support modern video formats. My second target - fastest way and using full power of my PC i working in Ryzen ThreadRipper 1900x 8c/16t processor and can test also at Ryzen 9 3950x 16c/32 and AMD radeon RX580 8gb video cards

Ideal for me would be usecase like this:

Preparation
0. Create several presets (in my case - 9pcs)
File name: [orig-name][append].[container]
Endocer: svt-av1 (and encoder-related setting like quality=45 and other)
Filter: Scale 0x720p Lancozs
and some other settings

Usage

1. open encoder and drag&drop video.mp4 (h264+AAC 30fps with high, not optimized for web bitrate like 21mbps from my video editing software)
2. select several presets at the same time to apply
3. click Start and get 9 output files
   3.1 Maximum (about 96%) browser-compatible formats in 3 steps of resolution (videocard-fast-encoded in h.264 ~5mbt bitrate like youtube recommended with AAC codec)
   3.1.1. video_1080p_h264.mp4
   3.1.2. video_720p_h264.mp4
   3.1.3. video_360p_h264.mp4
   3.2. Good (about 75%) browser-compatible and good file size optimized format in 3 steps of resolution (VP9+OPUS)
   3.2.1. video_1080p.webm
   3.2.2. video_720p.webm
   3.2.3. video_360p.webm
   3.3. Most perspective but currently low (about 40%) browser-compatible and best file size optimized format in 3 steps of resolution (AV1+OPUS)
   3.3.1. video_1080p_av1.mp4
   3.3.2. video_720p_av1.mp4
   3.3.3. video_360p_av1.mp4

And what nav1e features is missing for this case:

• drag&drop input file support (like in HandBrake if you seen its)
• in presets, simple text append support for file names
• mp4 container support (was remover from v1.5 and i am very sad)
• may be svt-vp9 support (implements like svt-av1 but my skills too low even for test svt-vp9 perfomance compare with ffmpeg+libvpx-vp9 with "-row-mt 1" and "-threads 16" whitch i using now and get a 60-70% CPU utilization, and for speedup i start two encoding processes simultaneously and get 98% CPU load!) OR libvpx-vp9 support
• simple h264_amf (or other HW accelerated codec) and libfdk_aac support

Option to let you see the encode window/terminal when using only 1 worker

suggestion: option (maybe under advanced?) to let you see the encode window/terminal
e.g. if you're using svt-av1 with just 1 worker

[Feature request] Vapoursynth support

Dear Alkl58, first of all thanks for making NEAV1E public and keep up this great work!

Are you planning to integrate Vapoursynth to create the pipe to the encoders? On my Core i7 8700K the ffmpeg processes often take up ~70% of the cpu, with only ~30% left for the actual encoders. Vapoursynth (or, more precisely, "VSpipe") is much more efficient (currently ~5%), so that a huge speedup would be possible.

No output file

The last build 1.0.7 doesn´t create an muxed output file!

Shuts down PC after encoding is finished. Toggle is set to off.

The shutdown after encode toggle is set to off, but it shuts down my PC regardless.

Filters won't work when splitting disabled

Crop is broken. When I encode with crop filter on, I'm getting uncropped image. When I'm encoding with crop and resize, both don't work, I'm getting uncropped image in original resolution. But resize works if crop is disabled.

'start encode' button not working

version 1.8
windows 20h2.

i press the button, it make the sound, but nothing happening. i press the pause button or the stop button and i get the message "encode has not started yet!".

i tried to change the settings, but nothing happens.
the original settings:
aomenc. speed 0. lowest file size. 2 passes.

No result after 12 hours of encoding after using "resume"

Boah! That was a hard blow!
I encoded a 2.5 hour video with aomenc. After 8 hours I had to stop and shut down the PC. The next day I used the resume function. The program opened correctly and also gave both folders, i.e. source video and output video. But when I ran start encode it found neither source video nor output video and asked for it. I have specified both folders again. After that the program resumed. After further four hours, the encoding process was completed and the muxing process was started and carried out to the end. So after a total of 12 hours I received the message that the process was finished. All the more my astonishment when I found out that unfortunately no result was received under the output folder !!!!!!!!!!!
No result there and all temp files deleted because I had set it up with the confidence that the program would work correctly. So 12 hours full power of my computer for nothing!!!
In the future I will always keep the temp files so that at least the video, audio and subtitle files can be merged with mkv Toolnix.

Alkl58, please check the resume function again and please fix the error!

The program is otherwise great. For processes without a resume it works excellently !!!

Best regards

[Feature\Bug Request]: Checking of frame correctness in chunks

Have issue with video\audio desync after encoding with SVT-AV1 and AOMENC.
Video desync seems to happen at random points in the encoding process. Had tested with audio passthrough and via manual extraction of audio from original video and merging via MKVToolnix with the encoded video.

Would like to request for frame checking of missed frames during or right after the encoding is fone that might have cause this desync issue.

Thank you

[Question] About subtitles

Hello Alkl58 and thank you for your work on this great program.

It is actually my standard "go-to" encoding program atm. 😃
I have several questions about the subtitle section in neav1e.

When I want to encode a series with one or more subtitle tracks already baked in the mkv file (you can select the subtitle in the player), is it necessary to actually activate a subtitle track in neav1e? The thing is that i can't select a track for it because there is no separate subtitle file for it, you know?

The other question is about the "burn-in" function of neav1e in the subtitle section: What does this option do? I can't find a help menu or mouse-over explanation for it.

Thank you in advance for answering my questions.

Kind regards

Constant "No Output File found"

program.log

First time using. Constant issue no matter how many times set/saved. Keeps asking "No Output File found" on Video encoding section.

Tried multiple parts, settings and even containers with different file names.

Thanks

[Enhancement] Audio bitrate setting clarification

Hello Aiki58,

thank you for your great work on this program. It really helps me in reducing the file size of my library. :-)
I have a improvement suggestion for you: The audio bitrate is as of my understanding set per channel. For the absolute beginner, it is difficult to understand that for example aac 160kbit/s is the mono bitrate and ends up being 320kbit/s in stereo.

A little addition in your naming convention or a mouse-over hint with "per channel" would be very helpful for these guys.

Thank you and kind regards

No output file file found!

Hi. After open app and select source video and output video and click on Start Encode show this dialog.

Checking Resume Mode not worked too.
Tested on: Pre-Release v0.9-beta

Edit:
This problem have filenames with special chars only. ... ěščřžýáíéúů (czech language chars)

Future: AVIF

Are you planning to make the same application to convert to AVIF format for images?

Batch mode not support change container (file format) type

By default, in batch mode for encode many videos, nav1e sets .mkv container, but it container not supported by web browsers and not usable for on-site videos.

It would be super feature, if .mp4 container will be added for batch mode!
