Cut Sections out of MP4

[peterhun]

I have some bad frames that I want to cut out of an .mp4 video with AAC audio.

Avidemux won't load it, Nero Vision won't load it, MP4Cam2AVI won't load it, Yamb is only a splitter/joiner. Sony DVD Architect won't work past the bad part.

I can't get Quicktime to Save. I can move the sliders to select edit points but it won't Save.

I have tried to convert to another container type but they all cease at the bad frames.

Players will play over the original bad spot and continue playing.

So I'd like something that will edit/cut the bad part out, keeping the good video before and after this. Is there any program that will do this please?

Mpegstreamclip for XP http://www.squared5.com/svideo/mpeg-streamclip-win.html

I can't make mpeg-streamclip Save. I click Save-As but the saved file is 0 bytes, even if I experiment and just select a 5 minute section. My file is .mp4, does it work with this.
If I choose Export it says Error: can't prepare movie.
What's going wrong?

The problem is your source file is FUBAR. Are your certain you can't cut it in Yamb 1.6 ?

I just tried Streamclip on a good .mp4 and it also gives me the same symptoms that won't Save.

I'll try Yamb again but it doesn't Cut sections only Trims from what I saw. I'll try to make working copies, trim them each separately then join them together.

Drag your MP4 into Gspot and post a screen shot.

Gspot shows it's exactly the same as a good file I have, the problem is some bad frames.

Nero codecs probably at fault for your inability to render the file in Gspot

Download this small script. I doubt it will fix the problems in your file, but give it a shot. At least it might demux the audio and video.

Thanks Soopafresh for your assistance. I ran the .bat and now gSpot displays audio and frame info but rendering a/v in MS still failed. The bad frames when viewed in Media Player are still there. So I think I'll try and cut this out using Yamb then rejoin.
