Help: MP4, frame-accurate editing, lossless/smart encoding, fast navigation

[BobP2013]

I'm trying to edit some mp4 videos, and have the following requirements:
1. Frame-accurate editing
2. Smart encoding (i.e. only re-encode the part that's required because of not editing on an I-frame boundary)
3. Fast navigation through the video to mark the parts that are in and out.

I haven't found a single tool that meets these requirements.
I'm thinking about using avidemux to mark the clips, because it has very fast navigation.
Then using solveigmm video splitter to do the actual splitting, because it'll do smart encoding.

To glue these together, I'd have to:
- Export the project script from avidemux
- Convert the frame numbers in the project script to times for solveigmm
- Run the solveigmm command line tool on this
- Also of course changing the script format from javascript to xml

Any ideas? Has anyone done this by any chance?

Thanks!

You're better off using 1 tool, like either solveigmm or videoredo only, both can do smart rendering

"Fast seeking" usually means various speed up tricks to ensure smooth playback , like frame drops. It's the opposite of accurate. Accuracy usually means indexing (slow). Moreover, taking the frame #'s from one application often won't match up with the 2nd application , especially if the 1st was a player . Different applications have different methods of error concealment and indexing, so they don't always match up

Thanks Death.
I really wish there was one tool that would do the job. Unfortunately, neither of those has fast seeking.
The TMPGENC toolkit comes the closest - tmpgenc authoring works has fast frame-accurate seeking, but not smart rendering (it builds an mjpeg index), and their smart rendererer tool has smart rendering but slow seeking.

Yep, I'm concerned about how the frames match up.

TMPGenc Authoring Works 5 has smart rendering for simple cuts, but it is basically an authoring tool with output for burning to disc, not a heavy duty editor. Go with TMPGenc Smart Renderer 4: http://tmpgenc.pegasys-inc.com/en/product/tmsr4_smartrendering.html.

Hey Sanlyn. Yes, I agree Smart Renderer 4 would be the tool for me. Unfortunately it does not have fast editing capabilities.

You have several ways to do so, and can customize it in preferences.

Smrpix, I probably wasn't clear about what I meant by fast navigation.
It's the ability to scroll quickly through a mp4 file, displaying video, without severe lag.
Then the ability to go frame-by-frame, again without lag.
AVIDemux and TMPGEnc Authoring Works 5 do a great job of this.

TMPGEnc Smart Renderer 4 doesn't have this ability.
In the preferences, there are some options for how much the keyboard jumps, but that's not really what I'm looking for.

Sorry for any confusion.
