I am new to video editing, and looking to build a custom PC (my old PC is dying).

I am wondering if I should go for i3 or i5 or i7?

I understand that i7 is definitely the best, but its also most expensive. Do I need something that powerful?

Also, does Snagit and Camtasia support multi-core and hyperthreading?

Thanks in advance.

Hi Kim,

Video editing is highly demanding on any processor. There is no such thing as a processor that is to fast or powerful for video editing. 

I run a 4th Generation Intel Core i7-4770 processor (8M Cache, up to 3.9 GHz). To me it's worth every penny. I can render a typical 1080P video at a speed under 1 to 1. In other words, a video that is 10 min in duration I can render in about 10 minutes or less. There are many factors that can increase render times. Special effects, editing dimension conflicts, etc.

I will also add that I do all my video work on a Desktop. A desktop costs far less than a laptop. The biggest reason is that lap tops need to function with low power consumption due to the need to run on batteries. High powered components are very expensive as a result.  You can get a high powered laptop but it will cost you 50 to 100% more than a desktop with the same specs.

An i5 processor can do a decent job with video editing. If you do very little video editing, then you could save a few dollars and go that route. I wouldn’t recommend running an i3 at all.

Bottom line, a i7 processor will give you the best performance overall.

Camtasia has no problem utilizing all the cores on my computer.

I haven’t really tested SnagIt for multi core rendering.  I will be perfectly honest, when it comes to SnagIt and recording videos I don’t care for it. On my computer it only records at a frame rate of 9 to 10 FPS. Any video that contains motion is very jittery as a result.

So I hope that gives you something to think about if you have any further questions I will be more than happy to try to help.

Regards, Joe

You may find this interesting. It's an exchange I had with another computer seeker in the past.

It comes down to your actual needs what computer may be best for you. Good luck and I would love to here what you've decided to do.

Hi Joe,

Thanks for your input and suggestions.

I am wondering which 'stage' of video production needs the power of a good processor the most?

I ask because I currently have a i7-4790 comp that I use for other tasks, and its in the basement.

I am trying to build another low-budget computer to be placed in my room (if possible, as low as an i3), The new i3 comp will mainly be used for 'recording' on camtasia only.

I will then bring it over to the i7 computer for editing and rendering.

Do you think this would be a good idea? Or would I need an i7 to record as well?

Thanks again!

If it's only screen recording you are concerned with. The i3 should be able handle that task with ease. You shouldn't have any problem recording video with either SnagIt or Camtasia on the i3.

A strong processor is best for the editing process and smooth timeline playback. Videos can render very slowly when using an under-powered processor as well. So having the i7 rig for any editing will serve you well.

I needed to expand on my response. The i3 will handle the recording as I said.

However, I didn't stop to think about what you are actually recording. What I'm referring to is that if you are recording yourself running a software program you need to account for needs of that program as well. The i3 really doesn't have that much left for running other programs.

Maybe it's best to just go with an i5. It's certainly something to consider.

Thanks Joe. Appreciate your input and info.

Now I just have to hunt for some i5 CPU deals in this case. lol
