Depends on how much degradation puts on the output file after rendering.

I am planning to release 6 micro apps in 2026.

Stay tuned to this thread ..

If you're fed up with being an unpaid QA tester for Microsoft, I suggest giving Explorer++ a try.

Probe Score Explained

The probe_score is a numerical value (ranging from 0 to 100) that indicates FFprobe's confidence in identifying the actual file type of a media file.

Key Characteristics
- Maximum Score: 100 - This means FFprobe is 100% confident the file extension matches the actual file type
- Low Score: Indicates potential file type mismatch
- Used during file type detection process

How It Works
1. FFprobe reads the first few seconds of a file
2. It attempts to detect the actual file type
3. Assigns a confidence score based on its analysis

Practical Implications
- High Probe Score (near 100): The file extension likely matches the true file type
- Low Probe Score (below 50): The file might have a misleading extension or be incorrectly encoded

Example Scenarios
- A file named "video.mp3" might actually be an AAC file
- The probe_score helps identify such discrepancies
- If the score is low, you might want to:
- Verify the file's true format
- Use extended probing to get more information

"format": {
"filename": "C:\\T\\Test\\B$_1.eng.aac",
"nb_streams": 1,
"nb_programs": 0,
"nb_stream_groups": 0,
"format_name": "aac",
"format_long_name": "raw ADTS AAC (Advanced Audio Coding)",
"duration": "293.218506",
"size": "5911505",
"bit_rate": "161286",
"probe_score": 51
}

I would like some good ideas related to potential functionality I can add
to my Metadata Editor.

I have 3 unused buttons as shown below ..

Current existing features:

1- Display Metadata for each file in a folder at lightning speed:
[Title, comments, streams count & types, duration, bit rate, FPS, resolution, DAR, encoded by]

2- Edit Metadata [Title, comments, encoded by (system)], fill the title tag with the file name in one click.

3- Extract, before or after Metadata to JSON file

4- Save Input media file with edited Metadata to output media file

5- Support any input, video, audio, subtitle, image, text, attachment, etc [still experimental]

6- Display executed ffmpeg command

7- Remove problematic binary/data streams [ex: tmcd]

8- Change output file name, suffix, folder, or full path

9- Move selected file to your Desktop [for further processing]

10- Delete selected file [with confirmation]

11- Drag n Drop files or folders

12- Basically, a more accurate Media Info replacement

13- Display thumbnails of selected media files [Images, jpg/jpeg, gif, png, bmp, Videos, mp4, mkv, mov, avi, etc]

14- Import Metadata from a text file

And more ... any ideas, or feedback, will be appreciated .. thanks in advance.

ffprobe detects embedded images when they’re stored as attachment or attached_pic streams,
and ffmpeg can extract those.

If images are in MP4 'covr' atoms only, ffmpeg can't expose them; re-mux or use MP4-specific tools.

Detect attachments (JSON):

ffprobe -v error -print_format json -show_format -show_streams "input.mp4"

Quick inspect:

ffprobe -v error -print_format json -show_streams "input.mp4" | Out-String

Look for "codec_type":"video" with "disposition": {"attached_pic":1}
or "codec_name":"mjpeg"/"png"

Extract attached picture (replace stream index 0:t:0 as needed):

ffmpeg -i "input.mp4" -map 0:t:0 -c copy "cover.jpg"

If there's a video stream with attached_pic disposition:

ffmpeg -i "input.mp4" -map 0:v:0 -c copy "frame.jpg"

If only covr atom (no attachment stream); re-mux or use external tools.

Re-mux to MKV then re-check:

ffmpeg -i "input.mp4" -map 0 -c copy "tmp.mkv"
ffprobe -v error -print_format json -show_streams "tmp.mkv"

Or use mp4box / Atomic Parsley to extract 'covr' atoms.

Thumbnail Generation in Windows 11 Explorer

Windows 11 uses an automated process to choose a preview frame that best
represents the video's content, with minimal user control over frame selection.

Mechanics
- Automatic frame extraction near the beginning or middle of a video
- Selects a visually representative frame
- Depends on:

1. Installed codecs
2. File format
3. System media settings

Limitations
- Not all video formats generate thumbnails equally
- Thumbnail creation varies by:

1. Codec compatibility
2. File type support
3. Installed media software

Troubleshooting
- Check Folder Options settings
- Clear thumbnail cache
- Verify codec installations
- Ensure appropriate file format support

I am releasing the first micro application a bit ahead of time
as a gift in the spirit of the holidays.

'Happy Holidays' everyone

The app is new and unsigned (yet), so it will produce false positives on Virus Total:
virustotal scan

keep in mind that most 'anti-virus' vendors have to come up
with imaginary threats (or fake viruses) to stay in business.

There is nothing to worry about. My App is totally safe and free of viruses and threats.

Edit:
Added Import Metadata from Text file ..
