Debugging codec mismatch when merging media

[satinesmith]

Hi folks!

A newbie here. Started video editing and caught myself in a bit of a pickle. Now I'm trying to debug a codec mismatch when merging media. Any help would be much appreciated!

I have some gameplay footage (Main.mp4) that has been recorded with NVIDIA ShadowPlay. I used a fragment of that footage to create an intro with Adobe Premiere Pro (see .epr for the Video Preset). Now I’m trying to append the two.

Exported, the intro (Intro.mp4) does not match with Main.mp4. Within SolveigMM Video Splitter 7 I get the 'Some files were ignored because of unmatched content with existing in the list.' error message. With Avidemux I get ‘Codec or codec settings across a cut point do not match.’ when trying to save the video. I also tried the nvidia encoding settings within Avidemux (Nvidia.mp4), but no luck.

I have exported the MediaInfo of both using MPC-HC. I see some differences, but I have no clue what settings are causing the mismatch. Since I'm not that knowledgeable of codecs (yet) I hoped you guys could help me debug this..

Thnx in advance! :D

The biggest obvious difference is that your main program is variable frame rate and your intro is constant frame rate.

Why didn't you just combine the files in Premiere? That's what it does.

Thank you for the input! And a good question. I'm planning on creating Gameplay footage on a regular basis. Using Premiere to render the whole film each time would take unnecessarily longer. Since the Gameplay footage doesn't need to be edited I can cut and append film in seconds using simple tools.

Try remuxing to a transport stream. Those are allowed to change pretty much everything between segments.
