AMVtool is a GUI created with Qt for FFMpeg that is geared towards the needs of AMV editors. In addition to handling almost all the formats that editors will use, it also helps out by automatically adjusting certain encode settings that are often incorrectly selected by many editors. Here are some of the features:
- Available on Linux, macOS, and Windows.
- Automatically chooses the color matrix based on the existing file or guesses based on resolution.
- Can pass through HDR or convert it to SDR.
- Easily copy video & audio streams from one container to another.
- Queue for batch encoding and easily configure all videos at once or individually.
- Shows bit depth of the currently selected video stream.
- Supports encoding of AviSynth (Windows Only) & VapourSynth scripts.
- Supports encoding to DNxHR, ProRes, Ut Video, VP9, x264, & x265.
- Supports multiple audio streams.
Configure vs Configure All
Configure will allow you to configure the settings for the currently selected file in the queue. Unlike Configure All, this option will allow you to select an alternate audio file to use when encoding and allow you to select which audio or video stream you want to use (if applicable). Configure All will allow you to change the settings for all files in the queue and will also be the new default settings for any new files added to the queue until the program is restarted.
Change Playback Aspect Ratio
This feature will change the playback aspect ratio for videos, however not all media players and editing software will honor the aspect ratio flag for x264 & x265 video streams that are copied instead of re-encoded. Most software will honor the aspect ratio flag for DNxHR & ProRes video streams that are copied.
