Slow render time

[thebrax]

Hi all,

We've been using our TriCaster Studio to do live webcasts of local high school sports. I have the TriCaster save the high quality output so we can archive the footage.

Since each game is about 55gb or so, I'm trying to render them out using the DVD 2 Hour preset, which reduces the file to between 5-6gb. What I've noticed is that it takes an incredibly long time to render the game. The current game I started rendering at about 10pm last night and it's now 2pm the next day and it's only at the 1:15 mark.

I hope this isn't typical performance. Is there something I've done incorrectly?

Thanks for any help you guys can offer.

If you were to do a Google search on slow render time for a DVD MPEG2 format, the list of pages listed should be huge. The proper term is encoding but that does not matter I only mention it if you want to do a Google search.
I know this does not help you but again I mention it as it is a common problem. I personally do my encoding on my quad core desktop using TMPGEnc 4.0 Xpress which takes advantage of the CUDA processors on my NVidia FX1700 GPU. I will also mention SpeedEdit 2.0 has a faster encoder than the one in TriCaster.
If you watch the video posted on a user that does live sporting events, he sends the events capture to a laptop to do his encoding one the way back to his studio.

Again sorry it does not help speeding up TriCasters ability but hopefully give you some ideas on how to do it outside of TriCaster.

Good luck,

I used "render" to match how the TC interface displays it. :)

Is there a better preset in Edit mode that I could use? I'm not real picky about the final format.

I had to do quite a bit of convincing to allow the powers that be to let me purchase the TriCaster, so to keep saying I need more equipment or software is pushing my luck.

It's too bad that you can't set your own encoding options.

The fastest render in Edit Media would or should be using TriCaster VCR (avi). It should render about double real time speed. File size may be larger or smaller I forget.
If you render to a Flash or WMV format, then you can have very small file size and real time rendering. But if it's DVD MPEG2 type encoding you desire, then for faster render times, you need to go outside of TriCaster.

Since you are just storing the video for archival purposes and you want high quality, why render it at all? And compression is going to reduce that quality. Huge extneral HD's are not expensive any more, and one that would hold 9-10 games wouldn't cost much at all.

If you must compress, DV is not a bad choice as José mentioned ... figure about 12.5 gigs for every hour of video.

Thanks for the info and help.

Now I've got a few options to look at in trying to figure out how to deal with archiving these past games.

Thanks!
