DVD is jumpy after conversion

[RebelUK]

Hi Guys,

Been away awhile, but have started using SVCD2DVD again to convert mkv to dvd however, the dvd is jumpy after conversion. I;m not using any matrices or matrixes the mkv file is NTSC format but the simple conversion method leaves the DVD result jumpy.

Any advice greatly appreciated

Thanks

Jumpy in what way?

Can you attach your log file for that particular conversion?
Have you tried the DVD in any other players?

Hi jagabo

It's jumpy in the way, once upon a time if you converted an NTSC DVD to PAL the picture skipped along, as if every 20 frames or so, the next few frames were missing. I have deleted the conversion now and am doing it again with use of the Fox matrix templates, just to see if it makes a difference.

I didn't burn it to dvd, I used Powerdvd to test the conversion before I tried to burn it.

Not using SVCD2DVD for my .mkv conversions, but lately I've been doing .mkv to dvd with another tool that uses QuEnc. I noticed some funky lateral movement, almost as you say like a frame is missing every so often. I tried using an .avs script to input the .mkv manually into HCencGui. I used a bitrate calculator to determine what to set in HC.ini. The avs I used was just 2 lines:
DirectShowSource("movie.mkv",audio=false)
Spline16Resize(720,480)

That gave me an .m2v file. I took the ac3 audio from the .mkv and just used an authoring program to mux them together. The Spline16Resize seems to be good when sizing down from HD to standard DVD res.

I'm thinking where QuEnc is a modification of ffmpeg if there may be a relation there. Just conjecture on my part though.

But I did notice with 3 or 4 conversions using HCenc that the lateral movement was natural in the resulting DVD.

That sounds like a bad frame rate conversion. For example, converting from 23.976 fps to 25 fps can be done by duplicating every 24th frame (and duplicating one more every 1000 frames to make up for the difference between 23.976 and 24). That creates a small jerk once a second.

The smoothest way to convert 23.976 fps to 25 fps is simply to decrease the amount of time each frame is shown (increasing the frame rate). But since the movie will run about 4 percent faster you have to adjust the audio to match. I don't know if SVCD2DVD can do this.

hmm,

I notice there is no longer the option to convert NTSC to PAL, but.... I do not want to convert to PAL my dvd player and most DVD players and tv's now cater for NTSC, so I guess there is no need for the cross platform conversion. it may well be because it is an HD (h264) mkv file ?

Thanks for the replies guys, still testing now

Firstly - could you upload a sample of the mkv file for me to look at this end, if i give you my FTP site?

Secondly. can you try the AVS wrap feature (you will need AVISynth installed) to see if that resolves the issue?

There is nothing inherently wrong with h.264/MKV that would cause jerkiness like you're seeing. But it's possible that your particular MKV reader or h.264 decoder is causing the problem.
