Trim Video with fade in/out

[nnowak]

I have video files from blurays, dvds, and hdtv recordings in m2ts, ts, and VOB format. I have been trimming these files with tsmuxer and DVD shrink followed by encoding to MKV with Handbrake.

I need some software recommendations (free or paid) from the collective wisdom of this forum. I am looking for something that will allow me to trim the files while also adding an audio and video fade in or out at the cut. Ideally this software would do a direct audio and video stream copy back to the original format and only reencode the couple seconds where the fades were inserted. I would then dump this output file into handbrake for final encoding. Alternatively I could do my final encoding right in the software that is adding the fades. The software needs to work with DTS audio.

My desired final output format is an MKV file with 1920X1080 h.264 video and 5.1 AC3 audio at 640k.

Nobody has any software recommendations? There must be something out there with what I thought would be a simple capability. In the interim, I have tested some other programs. So far Wondershare Filmora seems to come the closest, but it can only output 5.1 audio at 320K.

Unless I am missing something, I could not find any way to add an audio and video fade at the cut point. Also, I did a quick trimming test on a 1080p .ts file and the resulting segment was junk. It would only play the first few seconds without audio and then the video would freeze for the remainder of the clip.

An AviSynth example:

X=Last
A=X.Trim(0,10465).FadeOut0(45)
B=X.Trim(10466,10504).Tweak(Bright=-200)
C=X.Trim(10505,0).FadeIn0(45)
A+B+C

It also makes pure black some frames in between the fades. You could adjust the script if you just want the fades:

X=Last
A=X.Trim(0,10465).FadeOut0(45)
#B=X.Trim(10466,10504).Tweak(Bright=-200)
C=X.Trim(10466,0).FadeIn0(45)
A+C

You'll have to reencode the whole thing, so you'd do that losslessly. Or just skip Handbrake and feed the script to a real encoder. I have no idea how you'd do that with DD5.1 AC3 audio as I use WAV audio in my scripts.

This is one of those features that you'd think would be pretty standard, but inexplicably isn't. VideoRedo, for all its frame-accurate cutting and selective re-encoding, does not allow you to add simple fades in or out, despite the recommendation above.

To achieve what you're trying to achieve, I use TMPGEnc Authoring Works - as long as my sources and destinations are fully DVD or Blu-ray compliant. It's a really clumsy workaround, but I import (say) my MPEG file, add a two-second solid black video to the DVD track at the beginning and end, and add a crossfade transition between them. Then I output the DVD, and finally convert the VOB back to an MPEG file. Like I said, clumsy.

With all that in mind, I've never used it, but I think TMPGEnc Smart Renderer may be the thing for you. As far as I can make out, it's the same thing, but without the authoring functions. There's a free trial available, so download it and give it a try:

You're right: VideoRedo does not offer fade in/out. I also own Womble, which does do this, but only accepts some of the formats you are editing, and confused what Womble can do with what VideoRedo can do.
