Iris LQ/MQ
After reviewing user feedback, our research team has decided to split Iris into two models depending on input quality. Iris v1 will now be called “Iris LQ” and is recommended for very low resolution videos and highly compressed content. Iris v2 is showing better performance on medium-resolution videos (more than 480, less than 1080) and will now be labelled “Iris MQ”.
We believe this is the best way to communicate the specific strengths of each model, and we appreciate all the feedback that came in after the initial release!

v3.3.1
Released June 20th, 2023
Changes from v3.3.0
New export settings UI and options (details below).
Large list of “encoders” has been replaced with separate selectors for encoders – ProRes, H264, H265, VP9, AV1 – an associated profile/codec, and a GPU option if applicable (ex. you have both a NVIDIA and AMD GPU mounted).
Image Sequence options are given through a tab option now to separate UX flows for Video and Image Sequence exports. Similar to video encoders, we have added Bit Depth options for Image Sequence exports.
Removed “Auto” option for Audio Mode, default behavior is “Copy”. The UI should show an error if this is not possible for your video for compatibility reasons. (ex. PCM audio cannot fit in MP4).
Changed “Transcode” audio mode name to “Convert”.
When Converting audio, you have the option between AAC, AC3, PCM codecs. For MP4 container, you will only be presented with AAC & AC3. When exporting with VP9 + WebM container, the only codec option is Vorbis.
For AAC & AC3 you have the option to set a bitrate for the audio. AAC default is 320k, AC3 is 448k
Saved preferences from previous versions should be migrated to new preferences. ex. if you have a preference set to export as “TIFF lossless 8-bit”, your preferences in the new version should show “TIFF” for encoder and “8-bit” for Bit Depth and this should still be applied when opening a new video.
Added MKV container to extension options for VP9 exports.

Please take a look at the Video Roadmap Update 734 for more context on what we’re focusing on right now. Thanks in advance for your feedback!
Enhancement model - Iris
Primary aim of the model is to improve human faces
This model is also designed to enhance low- to medium-quality video, particularly, with noise and compression artifacts. Note, the model tends to lose details on high-quality videos
This model is trained to work on all three categories - progressive, interlaced, interlaced progressive
Please look at some examples in the roadmap post 734
Recover Original Detail
Purpose of this slider is to retain details from original source if the model’s output is overly smoothed
It adds the source texture details to the model’s output to bring back the original details

Iris LQ/MQ
After reviewing user feedback, our research team has decided to split Iris into two models depending on input quality. Iris v1 will now be called “Iris LQ” and is recommended for very low resolution videos and highly compressed content. Iris v2 is showing better performance on medium-resolution videos (more than 480, less than 1080) and will now be labelled “Iris MQ”.
We believe this is the best way to communicate the specific strengths of each model, and we appreciate all the feedback that came in after the initial release!

It also reduces the “previous frame’s ghost” artifacts.
It reduces “marching ant” (diagonal movement of texture) artifacts, especially, for 1x and 2x.

v3.3.1
Released June 20th, 2023
Changes from v3.3.0
New export settings UI and options (details below).
Large list of “encoders” has been replaced with separate selectors for encoders – ProRes, H264, H265, VP9, AV1 – an associated profile/codec, and a GPU option if applicable (ex. you have both a NVIDIA and AMD GPU mounted).
Image Sequence options are given through a tab option now to separate UX flows for Video and Image Sequence exports. Similar to video encoders, we have added Bit Depth options for Image Sequence exports.
Removed “Auto” option for Audio Mode, default behavior is “Copy”. The UI should show an error if this is not possible for your video for compatibility reasons. (ex. PCM audio cannot fit in MP4).
Changed “Transcode” audio mode name to “Convert”.
When Converting audio, you have the option between AAC, AC3, PCM codecs. For MP4 container, you will only be presented with AAC & AC3. When exporting with VP9 + WebM container, the only codec option is Vorbis.
For AAC & AC3 you have the option to set a bitrate for the audio. AAC default is 320k, AC3 is 448k
Saved preferences from previous versions should be migrated to new preferences. ex. if you have a preference set to export as “TIFF lossless 8-bit”, your preferences in the new version should show “TIFF” for encoder and “8-bit” for Bit Depth and this should still be applied when opening a new video.
Added MKV container to extension options for VP9 exports.
Known Issues:
The output settings of old presets may not be applied. Please modify them if needed

Please take a look at the Video Roadmap Update 734 for more context on what we’re focusing on right now. Thanks in advance for your feedback!
Enhancement model - Iris
Primary aim of the model is to improve human faces
This model is also designed to enhance low- to medium-quality video, particularly, with noise and compression artifacts. Note, the model tends to lose details on high-quality videos
This model is trained to work on all three categories - progressive, interlaced, interlaced progressive
Please look at some examples in the roadmap post 734
Recover Original Detail
Purpose of this slider is to retain details from original source if the model’s output is overly smoothed
It adds the source texture details to the model’s output to bring back the original details
