90% CPU while convertning .avi to .m2v (HCEnc)

[michcio]

Hi there!

I have used HCEnc for a very long time now while convertning my .avi's to .m2v's. The program works perfect but while converting it takes 90% of my CPU . Then when I open like 10 HCEnc's at once (to convert 10 avis) my comp. lagg really much. Shall one HCEnc client really take that much CPU?

cheers

Yes. Mpeg (actually, any video) encoding requires a lot of grunt. Any good encoder will have been written to make use of as much CPU as possible. If you are using a recent version of HCEnc then it will also be multi-core aware, and will use all two/four of the CPU cores if available. You will also find that in all likelihood, running ten encodes consecutively rather than concurrently, will get them finished faster because they wont all be fighting for the same resources.

I have the same quad core CPU as you, and don't feel the need to have multiple instances running. I find that batching them is far more efficient. Perhaps I am more patient.

If you really want to run this many instances then you need to buy more PCs.

10 instances of HCEnc?!? really?!? as a general rule of thumb you want an encoder to use up as much of your cpu as you can, as many cores as possible, so that you can get maximum performance assuming the application is properly multithreaded.

it would be different if you had a dedicated hardware encoder that was capable of simultaneously encoding numerous video streams and even then you would need quite a few harddrives to read from and write to not to mention a dedicated controller card.

perhaps you should look to see if HCEnc allows for 'batch encoding' where you create a batch file with a list of what files you want converted to what format and the encoder does each one on the list without any input from you.

tmpgenc supports this functionality, perhaps you should look into it.

10 instances of HCEnc , i almost laughed myself senseless.

thank you for answering =)

ah so converting from avi to m2v really need that much CPU ok...haha deadrats yeah to run 10 HCEnc at the same time are quite much but belive me I have run as much as 15 I think ...anyway guns1inger I would need more computers as you say haha :P...

I haven't find any options in HCEnc where I can just select 10 .avs files and then HCEnc take each one of them and encode without me selecting each one of them (I thought about doing a program in AutoIT where the user selects an .avi and then the program uses FitCD to create my .avs then convert it to .m2v using HCEnc, open the .avs file in VirtualDubMode where it saves the .wav (audio) and the opens ffmpeggui to convert my .wav into a .ac3 ... such a program would be really nice! will maybe try doing something like that when I got more time =))

Have a look at HCEnc Batch GUI : http://sourceforge.net/projects/hcbatchgui/

It may solve your problem
