Working with large .TREC files - Advice?

  • Updated 5 years ago
We capture whole days worth of webinar with trec file sizes that regularly exceed 4GB.

We then want to carve up the days into separate hours, working on each hour as separate project and still maintain full editing functionality. We add the trec to the timeline and then delete the the other 7 hours of content leaving just the parts we work on.

These projects are stored and maintained separately using the 'Export project as zip' option (its the way of our workflow), but each zip contains the same 4Gb+ trec file for each of the 6 or so segments of project which is a ridiculous waste of time and space.

We are based across the world, so opening/saving these type of  files over WAN/VPN is not practical, so we keep these files stored in and use desktop sync to manage the files. Hence the desire to a nicely packaged export-as-zip file.

Are we doing it wrong? Are there better ways of managing these types or projects?

Thx for any advice

suggest you make your captures in 1 hour segments and limit each project to just 1 capture clip, produce to MP4 with controller, and then host locally on your WAN/VPN

you could also periodically produce each project [during workflow] as AVI and continue editing using that AVI in the project

Also, you might check your recording frame rate. For strictly screen capture videos, I find recording my 1+ hour webinars come out fine at 5 FPS. If you are recording higher than that (i.e. 30 FPS...yikes!), your files will be much bigger than they need to be.

Thankyou. I am experimenting with exporting hourly segments into AVI using the Techsmith  v2 codec and getting odd results.

In the produced AVis I am noticing that every now and again the video seem to 'freeze' with no updates to the screen. The audio is describing how the presenter is opening dialogues boxes and doing stuff, but nothing is being shown. The video will then catch up after a few seconds. If I go back to the original .trec file, the screen out put is fine.

Any thoughts?
