Musicvid, Just sending one file would not help because it will play back fine even on my system. So I sent ahead and uploaded a 2 minute segment to onedrive. The project plays back better after removing all the other files from the timeline but I do still get audio dropping out during the 4th interview. Thank you for testing this...

I downloaded your project, but could not open it because I'm not running Vegas Pro 17. I dropped the .MXF files on to a Vegas Pro 15 timeline and experienced a multi-second delay when starting playback before hearing audio of seeing the preview update.

I converted each of the files to Magic YUV RGB with 48/24 PCM audio. Replacing each of the .MXF files, the preview was perfect and I experienced no audio defugalties.

Ok, so would you agree that my system is probably ok but the codec I'm using to render out from Resolve (Sony XAVC Intra CBG 300 3840x2160) is not ideal for Vegas? Thanks for checking it out. I guess i need to employ a different workflow when color correcting in Resolve. I'm not sure if I have access to the Magic codec in Resolve but I do have AVI (Grass Valley and Cineform). I did buy Magic YUV a while back so I'll look into retrieving it.

Not ideal for Vegas? Sony invented XAVC. And Vegas.

XAVC-I is system intensive, probably unnecessarily so in your case. Try XAVC-S instead.Your timeline and you may be happier.

Well... obviously if it's skipping on your system as well it's not ideal for editing. I'll look into other codec options and thanks again.

Well, it's not skipping on my system and I'm running a modest i5 8250 with onboard audio. XAVC-I previews with audio just fine.

No Vegas 17 here either, but I suspect your problem is some encumbrance in your project that you haven't shared yet.

I really try to avoid blame-placing, so good luck.

Hey Musicvid... sorry, I mixed you up with John Dennis who downloaded my files and confirmed they were also skipping on his system. Once he converted them to Magic YUV they played perfectly. I'll be trying other codecs in the future to see what works best as the version of XAVC I'm exporting from Resolve is obviously not ideal. Thanks I appreciate everyone's help is trying to help me solve the problem.

I found that putting the .MXF files from Resolve on the Vegas Pro timeline and rendering to XAVC-Intra, playback performance improves without generation loss, increase in file size or any other obvious down-side risk except the time it takes to do it.

It's equivalent to a rewrap.
