Multicore Conversion Programs

[Merkaba188]

I usually just use ConvertXtoDVD when converting XviDs to DVD for family and friends, but I have a Philips DVP5990 standalone that I use for myself. I used to use a thumb drive and pop that into the front USB port on the player, but recently it hasn't been working right. It used to show the progress of the video loading for a minute or so before it would come on, but now it just goes straight to the video. Ever since it has been doing this I can never watch the full length of the file. it usually just stops at about 1:30 into the movie. I can fast forward past 1:30, but as soon as I press play it stops again. I know its the player and not the flash drive because the video plays to the end when watching from the flash drive on my computer. Anybody have an idea what could be causing that?

But this isn't really that big of a deal because I have 100's of CDRs that I can burn to, which my player has no problems with. The main problem is that a lot of the files I have are 1-2GB and I don't have very many DVDRs, so I have to split the file into 2 CDs. Right now I'm using AutoGK to split the file, but this takes forever. I have a Quad Core CPU and 4GB of RAM, but in task manager it only shows VDub using ~15% of my CPU and ~150MB of RAM. I bump the priority to Realtime and it still only goes to 30% and 225MB.

I guess my question is what else can I use other than AutoGK/VDubMod that will use more resources and take advantage of my hardware? I wouldn't mind at all if conversion would max out my CPU at 100% so I could get the final product quicker. There has to be some newer software out that utilizes multiple cores.

Ram usage is not a biggie. Your ram usage looks pretty normal. CPU usage is very poor though. When I use AutoGK I tend to encode using Divx because it is a much better multi-CPU encoder than Xvid. I generally get around 80 - 85% utilisation from my Quad core.

The later Xvids are multi-CPU aware - perhaps it is time to update your software ?

[Merkaba188]

I'm using Xvid version 1.2.1 right now, going to update to 1.2.2 to see if it makes a difference. I don't think it will because the changelog doesn't really mention anything other than some bugs, and 1.1.3 and before were the versions that didn't support multicore.

I guess I'll try using Divx instead. Is there any noticeable quality difference from Xvid to Divx?

When you say "split the file" are you talking about .avi input? If so why reencode? Just split into 2 pieces using AviDemux. (If this answer doesn't make sense then maybe I misunderstood the question.)

Often I go the other way. Take 2 .avi and Append using AviDemux which automatically rebuilds frames and other stuff if the input needs it(if everything in the Automation Tab is checked.) The output file is written to disk in a couple of minutes.

[Merkaba188]

Yeah I meant take a 1.4GB .avi Xvid and split it into two 700MB files. AutoGK is now giving me some major sync issues, so I'm manually doing it in VirtualDubMod right now.

I'll have to check out AviDemux for sure, this should work great if I don't have to re-encode. The only problem is I have some subs that I want to hardcode into the file, and I don't think AviDemux will do that. AutoGK adds subtitles and splits all at once, but now its going way out of sync.

I just tried hardcoding some subs with VirtualDubMod using this guide:
https://forum.videohelp.com/topic272736.html

It worked great other than the fact that I got an output of 1 780MB file. It reduced the quality quite a bit, and on top of that I still can't fit it onto 1CD. Is there any way to manually select the output size? I'm guessing its somewhere within Video->Compression->Xvid->Configure, but I'm lost in all of those settings. Anybody have a link to a guide for that?


*EDIT*
I just found these 2 guides for AviDemux:

WOW

AviDemux lets you manually select 4 cores, I added subtitles and split the movie, and the output was the EXACT same quality as the original.

It did all of this in about 45 seconds.

ROFL I am such an idiot.

You can do the same thing in VirtualDub by using Direct Stream Copy mode for both audio and video. It will run just as fast as AviDemux. This requires virtually no CPU time. It's I/O limited.

When you say added subs, do you mean burned in or selectable? When you talk about processing it so fast I want to make sure I don't miss out on something here.

Can you give more details?

Unless his video was only a few minutes long there is no way he burned hard subs and reencoded the video. You're not missing out on anything.

Yeah I can't even figure how he could do soft subs and cut it. Must have cut clips and then used a subtitle program to create text subs for each piece.
