Issues after employing 'shot match' feature

I have edited a 4 camera video shoot, that also includes a 12 track multi-track digital audio soundtrack. (I taped a 40 piece orchestra, and recorded the audio using a Zoom R16 digital multi-track recorder, for the audio) Because one of the cameras employed was a Canon DSLR, I had to use the 'Shot Match' feature to match the DSLR to the 3 remaining matching Panasonic HMC Series video cameras. The edit is complete. it's 41 minutes long. Shot in 1920x1080p. 30fps. But now, during playback, the video will stop after about 30-35 seconds of play. No reason is given. It just stops playing. I haven't burned it to Blu-ray yet. I was playing it back for final visual verification. No matter where I begin play of the 9 chaptered video, it simply stops after 30-35 seconds of play time. I've been utilizing MEP since 1999, so I'm not a novis. My computer is a Windows 7 Ultimate 64bit, with a liquid cooled Q9550 CPU, (Overclocked to 3.55 GHz), with 10 gig of DDR3 RAM, an EnVidia GTX750Ti, with it's own 2 gig of DDR5 RAM. I'm employing MEP 2017 Pro Plus. I've never had this issue with any previous versions of MEP. Does anyone know why it stops playing? Or, has anyone experienced the same thing? I currently have version 16.0.3.66 This is the 3rd time I've edited a video for this client and his orchestra. However, the previous videotapings only encompassed 3 exact video cameras, and required no 'shot match' utilization. Anyone have any thoughts? The computer has no other issues with any other software.

. . . . 4 camera video . . . . a 12 track multi-track digital audio soundtrack . . . . to use the 'Shot Match' feature. . . .

Shot match is a very processor intensive effect and depending on the track arrangement, e.g. Multi-cam editing was used, is enough to reduce any PC to a crawl / stop when viewing in the Preview monitor

If you have not done so try the following:

Turn on Proxy files in the projects settings
Render the timeline for smoother playback
Export to mp4 to test

Good to see someone else has struck this issue. I have observed it also with VPX and was starting to think it may be my system. In my case it occurs with 7 short 1080 50P 3 - 8 sec clips all with Shotmatch and little else. It never plays through them all without quitting. It is almost as though the PC runs out of RAM but TM shows no unusual increase in usage. Playback is smooth until it stops.

The feature, when first added in VPX8, was very heavy on processor load and one of the subsequent updates indicated that they had made it less resource hungry, which it now seems to be.....but this???

I have not exported the projects I have found the problem on, have you Mojoaudioguru? The only other thing I see common at present is Panasonic. My footage is from an HDC-SD900.

Hi,

This is not a solution to the Shot Match problem but a workaround. Did you try exporting to mxv and running that in a project. If that works, then save the original project, do a save as with a new name, delete everything from the timeline and replace it with the mxv file. I think that the chapter markers will still be in the correct locations, but you should check.

This is my procedure when I use Neat Video to any great extent. Otherwise, the encoding takes a very long time and has sometimes resulted in stuttering in the output file.
