View Full Version : should playback of the M2V on my system be jerky?

I've now got my source looking like I want and I am encoding into mpeg.

I'm using TMPGENC to make it an M2V file and I choose 2pass vbr @ 4550.

If I play this back in Powerdvd, the first time it plays, the hard drive thrashes itself to death and gives jerky playback, if I let it play through and then play it again, it doesn't access the drive at all and playback is lovely and smooth ( I assume the system has cached the movie or something by this time)

should I be worried? if it jerks at first time playback on a system,would it do that in DVD form or not? I tried dropping the bitrate down to a 3650 average just to see what would happen and it was the same.

I've not yet made this a VOB yet. could it be that my system has trouble handling a large mpeg 2 file but if it was a VOB and it classed it as an on-board DVD it would be fine?

is it a warner bros dvd ?
if so have you stripped out the 12 second logo ?
if not this may be the answer ?
I havent tryed tmpeg but I have had probs with warner bros pictures :confused:

this is a capture from an analogue source.

like I say, the mpeg plays fine if I let it play through and then rewind for a second play.

this sounds like a cacheing issue with the hard drive but when I play other video files in media player, no problem.

if I play it in media player it's okay, but obviously doesn't sync because it's a 24fps progressive video.

if I made this into a VOB and DVD structure, does anyone think the jerkiness will disappear? could it be the computer has trouble with playing such a large mpeg file. but would cache a vob structure properly?

My system would do this until I updated my ViA 4in1 drivers. It sounds like your system is just having difficulties.
Try burning it and seeing it if it works in a standalone.

You may also be having problems due to the need to defrag your harddisk.

yup that done it.

harddrive was fragged. did that and it is smooth as silk. god I love it when you finally see the reward playing smooth and sharp.
