Panasonic DVD-S35 DVD-R & DVD read bit-rates

Hello,
Does anyone know at what bit-rates the Panasonic DVD-S35 reads dvds and dvd-rs?

Thanks,

I don't understand the question and if I don't understand it then I am sure other people will not understand it.

Can you please be more specific what it is you are asking here?

It sounds to me right now that you are confused with your DVD terminology.

I've never seen a Panasonic DVD player that won't play DVD-Rs in any speed from XP to EP, and I had the first DVD player Panasonic ever made.

I have been converting avi files to dvd format using ffmpeg. I can adjust the bit-rate of the target file. When I encode a dvd with a video bittrate of the suggested 3000 kbit/s (using best option on the video tab), the dvd-r stutters or skips on my panasonic dvd player. The same dvd-r skips super bad on a PS2 and runs more smoothly one of my buddies dvd players.

When I encode the dvd with a bittrate of 1500 kbit/s, the dvd runs smoothly on my panasonic dvd player.

I figure they must read the dvds at a different speed, some reading data faster then others.

So I figure my panasonic has a specific rate at which it can read dvds, like 1500 kbit/s. Am I way off or something?

At what bitrate I should encode my dvd-rs at for my panasonic dvd-s35?

Thanks,

The DVD format can handle a total bitrate of just over 10,000kbps although normally you don't want to go over 8000kbps for the video and that is with MP2 or AC-3 audio. If using PCM WAV audio then it's best to hold the video bitrate back to 7500kbps.

The figures you are talking about are WAY low.

You are mixing the terminology a bit. A dvd player reads at 1x. That is the constant rate a player will read a dvd to display the video and sound.

This is taken from the dvd demystified faq:

Note: When playing movies, a fast DVD drive gains you nothing more than possibly smoother scanning and faster searching. Speeds above 1x do not improve video quality from DVD-Video discs. Higher speeds only make a difference when reading computer data, such as when playing a multimedia game or when using a database.



The video bitrate is the quality of the video itself. It can go from vcd level of 1150 with audio at 48khz up to about 10,000 as fulcilives mentioned.

I guess I was a bit off

I dont understand why a dvd a encode at 1500 kbit/s runs much more smoothly then a dvd encoded at 4000 kbit/s on my home dvd player.

What should I do differently to get a dvd-r encoded at 4000 kbit/s to run smoothly on my dvd player? I am using TDK 16x dvd-r. I have tried burning at 1x and 2x, but it did not make a difference.

Thanks so much

I'd suggest using a different program than ffmpeg for MPEG-2 DVD spec encoding. If you want a freeware solution try Quenc (which uses ffmpeg but only for AC-3 audio which is A-OK).

Other popular solutions that cost money but are fairly inexpensive include CCE Basic, TMPGEnc Plus and Procoder Express.
