One of the most infuriating errors when video editing…
Imagine. You have spent a full day filming an event with 4 cameras and then spent:
- Hours offloading and organising all the clips
- Many hours lining up the clips from 3 or 4 cameras
- Another couple of days carefully editing the whole lot
- Hours researching and adding music
Then you get to that lovely point where you are ready to render out for production of the clients’ DVD.
For some longer jobs, this render can take up to or over 5 hours depending on your computers power so I tend to, if possible, render it overnight so the computer can use all its resources on this rather having me “fannying about” in the background doing other things.
Beware the rogue clip!
So, imagine my horror this morning, when I am already on a tight deadline to get this job out to a client today, Bank Holiday Monday, and I play the rendered clip.
I can’t understand why it:
- Has taken so long to render for just a 30 minute video
- Is nearly an hour long instead of 30 minutes
This is why…
If you have a rogue (stray) clip far along your timeline (from previously clipping and cropping edits) and you either forget it is there or forget to “render loop region only”, then your editing suite will assume that this is part of the final edit (why wouldn’t it)?
This means you will end up with, like I did, the first 30 minute clip rendering perfectly and then around another 30 minutes of blackness playing until it reaches that rogue clip and finishes with that.
Now the clip has to be re-rendered but here is a handy tip that may help to speed up that process.
Rather than render out from the original edit, take the rendered video (with rogue clip) and pull that into a new project. Cut the rogue clip out (or simply loop the section you want to produce) and render that.
This can be around 3 or 4 times quicker than rendering from the original edit. I am not sure if you lose any quality doing this but in my case, I am rendering to 1080p but outputting to DVD so it should be ok and delivered on time!
