Just encode some part of video

[ben45]

Hello
I want to encode some part of a video and passthrough other parts. lets say i want to encode from 3 to 4 min
Is it possible without splitting video?
I use megui with x264

Hi, you can use the trim function of avisynth, open video in virtualdub to know the frames needed.

have you tried avidemux? load video, cut/delete unwanted video and convert with x264.

I need whole video but i want to encode some parts. I want to get single output file

I doubt you'll have much luck even if you do split it. It can be very hard to match encoder settings, which is a requirement to successfully append video (different CRF values or bitrates are okay as long as the rest of the settings match). In fact even if you encode two videos using exactly the same encoder settings, there's no guarantee they'll append successfully unless you add --stitchable to the x264 command line. Quite often I encode a whole video and then want to re-encode just a small section of it for some reason, so I keep the --stitchable option enabled all the time. You'll find it under the Misc tab in MeGUI's x264 encoder configuration.

Add "--stitchable" option for segmented encoding.

MeGUI has an AVS Cutter under the tools menu. If you want to try re-encoding you can use it to add "cuts" (using Avsynth's Trim function) to a script to encode just the bits you want, but you'll need to split the original manually, re-encode the bits that need it, then append the sections together yourself. You can split and append with MKVToolNix. If it doesn't think the appended video matches it'll warn about potential playback problems, which is often what happens if --stitchable isn't used. The video will decode successfully until the point where it's appended, then it doesn't.

Thankyou!
Please help me slove this problem. I have about 500 videos ( each 5 h). I want to remove an ad logo from 6 to 10 min of each video.
Is there any way i can remove this ads without any playback problems?
