Sujet: vob vs mp4...which requires less system resources?

Ce topic est ancien et peut contenir des informations obselètes ou incorrectes.

I'm not particularly concerned about a slight loss in quality but which of the two takes less system resources to load and play on a PC with VDJ and a Hercules Rmx setup?

VOB.
 
VOB & M4V I'm impressed with the quality.

Joey..
 
Joey, is mpeg4 the same as m4v?
 
Yes...iTunes Standard.

Joey...
 
I think it also depends on your video card.. (but don't quote me..)

I know my video card says it mpeg2 and mpeg4 (h.264) capable..

myself, i dont notice much of a difference in load times or CPU usage between them.
 
Mp4 uses a much higher complexity format than Mpeg2. (VOB uses MPEG2 as it's video compressor) There's no question that Mp4 requires more power to load (Decompress) and with older processors it's normally visually obvious when loading the file. (Slower)

The two primary advantages for Mpeg2 are quality and they use less computer resources which could make the difference between crash or burn for some folks and their machines. The disadvantages are files sizes and no tagging ability.

Thank you DJRene....the exact answers I was looking for.
 

Video cards like N-Vidia decode MPEG-2 in it's video core and not using all CPU resorces. While MP4 needs CPU to decode it. VOB got the same quality of DVD quality.

Many of the video cards also say they decode mp4 now..

of course I have no idea if VDJ is able to take advantage of that..
 
My laptop is 2ghz processor and 3gb ram, 512mb video card. I'm very happy with my set up but it could be better. I have occasional freezes and just basic goofiness here and there but I'm starting on a shoestring and the effects are minor compared to the guy down the street not running any video lol. My question is how much would a more powerful pc(say 6gb ram or better, quad core) improve these slowdowns. I mainly use mp4.
 
To Staelyaic: Check the Thread on Video Freezes...Getting a more powerful pc does'nt mean you will get rid of Problems,..especially with Windows 7.you should wait on that one for now..

You'd be amazed at what more RAM can accomplish. Particularly in my scenario.
 
I was running mp4 on an earlier version fine. I upgraded to newest vdj and now have issues. Guess I better downgrade.
