• Top-left corner contains the tabs for the main functions of the app.
• Left-side of the window is the output console, drag & drop your files here to start processing.
• Right-side of the window contains settings for the conversion.

"Probe" tab

This one uses ffprobe.exe to display every possible media and codecs information of a file. There’s no settings panel for this one.

"Convert Video" tab

This one uses ffmpeg.exe to convert video file to a different format. Use the settings panel on the right to set the output parameters, then drag & drop the video file or files to the output console on the left. Processing will start immediately when file is dropped.

• Codec
• Supported codecs are H.264 and H.265. I did not add hardware acceleration option because it produces lower quality result, which is unsuitable for archival, which would be the main purpose of this app.
• Transform
• Downscale 4K to 1080: Converts video to 1920×1080, if source is exactly 3840×2160 in size. Works both for landscape and portrait orientation.
• Drop audio track: Output will not have audio. Saves on size if audio was irrelevant or unwanted.
• Quality
• Constant Rate Factor: Maintains a consistent quality level for the video (with changing bitrate). This means the output size will be bigger if the video has more movement or high frequency details, but saves a lot on blurry and mostly still videos. Default values is 23, lower value means better quality and bigger file size.
• Fixed size: Automatically calculate quality level (at fixed bitrate) to generate video at the desired file size. This is good for chat clients where file transfer has a size limit. Result file size might not be an exact match, so for 10MB, might worth setting it to 9.5MB.

"Images To Video" tab

This one uses ffmpeg.exe to convert a sequence of images to a video. Use the settings panel on the right to set the output parameters, then drag & drop your images files all at once to the output console on the left. Files will be used in alphabetical order!

• Image Sequence Options
• Base frame rate: Frame rate of the output video (without frame generation).
• Generated frames: This will add generated frames in-between the input images for a higher frame rate. Having a base frame rate of 30 with 1 generated frame will create a video at 60 FPS. Warning: Frame generation is very slow! You can use the Terminate Process button on the toolbar if it takes way more time than expected.
• PNG background color: Input images can be PNG with transparency, but the output video cannot have an alpha channel, so this color will be used as background.

Toolbar (top-right)

• Terminate Process: This will terminate current conversion process. Output file will still be generated, but will be empty.
• Settings
• Verbose output: By default, output console will display a simplified output on the current process. Turn this on to see everything printed by ffmpeg.exe. (this is for debugging only)
• Add to Start Menu: Click to create Start Menu shortcut for the app. Might need to start app with Admin privileges first.

Latest FFmpeg requires Windows 10 or newer to run. Alternatively you can use ffmpeg-release-essentials, which does support Windows 7 (https://www.gyan.dev/ffmpeg/builds/).
