frame-rate converting tool

Posted by Tobias Trummer on June 28, 2011 at 8:00 am

we currently make a test drive for frame-rate conversion (1080@24 -> PAL and NTSC -> PAL).
formerly we did that with Vegas but nowadays field blending isn’t
uptodate…
we now try episode with rather good results.
Tests with AVISynth lead to good results but only for destination @ 50p – where can’t get to 25i in a good quality.

Are any HQ tools known here for such jobs?

Thanks in advance,

Tobias.

Software wise? Both Episode and Squeeze do a decent job of frame rate and format conversion.

Hardware wise? A terenex or a snell and wilcox will do this too.

Also, if you have an HD deck, these things may be possible in RT.

Hi, thank you Jeff.
Is that all?? 50K against 1K ? My searchings seem to lead to the same results.
I guess there must be a 7-10K software out there…
Even Carbon or MC do worse than Episode. Also any NLE.

I’ve heard about a PlugIn to Carbon of a Mexican software – but I forgot the name. It’s very hard to find things in the https://www these days.

More, more please!

We also try AVISynth. But that’s a hard and long road to find the right plugIns and then write the right code with the best parameters…
If anybody has a Input for that… you’re welcome.

Well, on the PC side, there’s some stuff from Rhozet and MainConcepts, as well a couple of others…including compositing software like nuke.

It comes down mostly to whether or not they’re using some level of frame blending or optical flow.
Most of the optical flow is down in software.

Telestream does some distributed computing that your budget might be able to afford.

Jeff,

we tested both: MC and Carbon. None of these was as good as Telestream. But Telestream only is useful for frameblending. we have negative experiences whith motioncompensation or other advanced methods when aplying it to “heavy” material. There are too much errors. not useful for a standardtool for standard conversion.

What I mean there is a lack between the 1K and the 50K (and corresponding the quality!) that’s beeing filled… for what I found.

AviSynth could do it as you can remodel almost every algorithm within it. But that’s hard to find out.

Tobias.
