I've never edited a film that ran longer than 20 minutes. So this is a sort of newbie question. I just completed a 1hr & 2min. length film. About how long should it take to render this as a standard MPEG 2 file?
As the old teaser has it, how long is a piece of string?
Much will depend on the horsepower of your machine and the number and type of FX you have applied. As a rough starting point, why not say three times the length of your twenty minute film? In other words, try it out and see what happens.
Not trying to be unhelpful but this is such an open-ended question that does not have a simple answer.
The only FX I used was Sony Sharpen. It's about 70% HD video and 30% slides & text. So, pretty straight forward. I thought my PC specs were posted (just click on my profile for full system specs). It's an ADK Win7/i7 64bit unit with 12GB of RAM. Does that help with the estimate question. BTW, it's rendering as we speak. I just wondered how long I'd be waiting for it to finish.
On my older, wimpier laptop, a render from HDV to DV (NTSC) with various color corrections and transitions would take between 5x - 8x the length of the project. Thus a 3-minute segment might take between 15 and 24 minutes.
