Conversion Program that will import Video file settings

[tonyaldr]

Do any of the video conversion programs out there import a video file's settings and use it as a preset for conversion of other files? Or do I need to use mediainfo and input the preset manually using the displayed values? In other words, let say I have an mp4 that has great quality and a small size and other mp4's using the same codec that are larger. Is there a program that will scan the former file and adapt the preset values in order to allow me to convert the others? Thx!

Doesn't usually work as you envisage it. Usually you pick an output profile that's close
to what you want, and the source details are not that relevant

I figured that but thought maybe someone had come across some obscure app that actually did that. Thx.

Which properties of the source file do you want to be picked up?

Pretty much items that I see as reported by mediainfo - Mux type : MP4, Encoding : H.264, VideoStreamID : x201, Frame rate : 30.00 fps, Encoding size : 1280 x 720, Aspect ratio : 16:9, Header bit rate : 14.000 Mbps, VBV buffer : 256 KBytes, Profile : Main/3.1, Progressive : Progressive, Chroma : 4:2:0, Entropy mode : CABAC, Bit rate : 2.165 Mbps, Captioning : EIA 608/708, Audio Stream: 1 (Primary), Codec : AAC, Format : RAW, Channels : 2.0, PID : x202, PES Stream Id : xC0, Sampling rate : 48000

I have two copies of a 2.5 hour MP4 file at the same 1280 x 720 size, that are a gig difference in size and the smaill size one plays with fewer pixelations at fast speed than the larger one.

You might be better off posting the whole medaiinfo report (text view) for both a good and a bad encode.
Usually for H.264, you pick a preset (usually Medium or Slow) and a quality value (CRF) of 18-22 or use 2-pass VBR
encoding if you'd like to target a specifc size

In general trying to convert a marginal encode of typical consumer video in the hope it will get better is usually disappointing

ok. thx!
