I'm currently in the process of transcoding a few thousand videos but they are all from different sources so things like the video/audio encoding are different, resolution, etc
Is there a tool that would allow me to list out the following information for multiple videos so I can locate outliers?
- video encoder
- resolution
- aspect ratio
- audio encoder
- audio samplerate
- audio birate
- and it would be super-duper helpful: is interlacing detected
Try StreamFab Downloader and download from Netflix, Amazon, Youtube! Or Try DVDFab and copy Blu-rays!

I have actually never come across this before! I've been using a weird combination of avidemux and vlc to get all of my data.
Thanks for the tip! I just installed it through homebrew and it looks to be what I'm after. Strangely, there is a CSV accessible from the terminal but not in the GUI, still looks like a great app! -
You can use ffprobe (part of ffmpeg distribution build). Script similar to one bellow may be used to extract interesting for you data (add fields interested for you).
Code:@set nme=%1 @ffprobe.exe -v -8 -i "%1" -show_format > "%~n1_format_streams.txt" @echo - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - >> "%~n1_format_streams.txt" @ffprobe.exe -v -8 -i "%1" -show_streams >> "%~n1_format_streams.txt" @echo - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - >> "%~n1_format_streams.txt" @ffprobe.exe -v -8 -i "%1" -show_entries "frame=coded_picture_number,pict_type,interlaced_frame" >> "%~n1_format_streams.txt"

MediaInfo has a CLI interface that can be called from a bat file that has almost every piece of information about a file there is, including Scantype(Interlaced/Progressive)
First create a reusable template (template.txt) to request the information you require: e.g.
Video;Resolution = Frame Rate = %FrameRate%\r\nVideo Codec = %CodecID%\r\nVideo Format = %Format%\r\nScan Type = %ScanType\r\n
Audio;Audio Codec = %CodecID%\r\n
C:\{path to program}\mediainfo_cli\mediainfo.exe --Output=file://"C:\{path to template}\template.txt" "C:\{path to videos}\Video.mpg"
Resolution = 1920x1080_
Frame Rate = 29.970_
Video Codec = 27_
Video Format = AVC_
ScanType = Interlaced_
Audio Codec = 129_
BE VERY CAREFUL WITH CAPITALIZATION, FORMAT, SPELLING AND QUOTES -
Hi,
sorry, I didn't know there is someone that doesn't know about Mediainfo . My fault.
When you select which files are interlaced and which not, you can do quality based encoding. If your target is h264 or h265 codec. Just find what is your ideal quality for video. It is resolution and frame rate independent. Size of videos (same time, same resolution and same fps) will vary depends on video contents. But it is faster than 2pass encoding and "same quality guaranteed". Of course if you have video in poor quality it will not helps it, but at least worth to try it.
It is Constant rate factor (CRF). Lower settings higher file size better quality. Higher lower file size lower quality. That method of encoding can save you lot of time.

MediaInfo will show Field Order if you add 'Scan Order = %ScanOrder% to the Video line show in the thread #6 above;
The result will be:
C:\Users\Bud\Desktop\MEGA_Trimmed_Tabbed_2_2\bin\D ebug>MediaInfo.exe "--Output=f
ile://Template2.txt" C:\Users\Bud\Desktop\Frame.mpg
Resolution = Frame Rate = 25.000_
Video Codec = _
Video Format = MPEG Video_
Scan Type = Interlaced_
Scan Order = TFF
Audio Codec = _
Channels = 2_
Audio Bit Rate = 128 Kbps_
For a more definitive inquiry you could use FFMPEG '-vf idet' filter as explained in http://www.ffmpeg-archive.org/field-order-detection-numbering-framepositions-possible-td4674257.html
