weird things above my MPEG movies

[uklad24]

I use a Panasonic DMR-E30 recorder to record stuff from television. I usually record them onto a DVD-RAM disk and then dump the files on the PC to author them and eventually burn them onto DVD-R.

Something I have noticed recently is that when I record from certain digtial satellite channels, when I view the mpeg files on the pc (in any kind of dvd playing softwear) I get all these little white flashing dots at the top of the picture. Also, if I transfer a VHS onto a DVD, there is always this band of intereference at right at the bottom of the video. When I burn them to DVD and view them through the television they're in the over-scan area and you can't see them. They're only visible when watching them on a PC monitor, and can be a little distracting........

Does anyone have any explanation as to what these are, and if possible, can they be eliminated. I noticed you can clip the top/bottoms from files using TMPEGEnc but that means having to re-encode the videos again and I don't really want to do that.

thanks in advance

When I record off TV I get this too. I guess it has to do with the signal transfer through component wires I (and maybe you) used. Remember that when you do this your recording off of an analog source.

Yes, recording from the VCR it would be analogue, but from TV I record directly from Digital satellite using high-quality Scart leads. The DVD recorder is completely digital anyway, so any signal coming into it is digitised before being written to the disk - even the sound is written as Dolby Digital Stereo, no matter the source..

That "any signal" would be analog converted to digital, in which there is quality loss. And sure you can convert stereo sound to 5.1 Dolby but your not going to have 5 channels of audio, instead, just two.

On your "little white dots" question, I have experienced this, it is when I have an overlay in the background (TV application running) and am playing the recorded video in my media player. Close your TV app and see if the file is OK. If this doesn't solve it I can't help you on that.

On recording from VHS cassettes, that is standard (there is a line of distortion that runs along the bottom of the picture) the only way to eliminate this is by re-encoding and cutting it (as you stated). I make DVD's for watching on my TV so the VHS distortion isn't a problem as TV's have a smaller view area than PC monitors.

How is the recording to DVD-RAM and capturing to PC working out? I've been pondering about doing that for a while but am still unsure.

g_shocker182 thanks for your comments but you keep mis-reading my posts. The initial signal is DIGITAL, there is no analogue source, and I didn't say my recorder converted stereo to Dolby 5.1. I said that any audio source is kept as stereo, but compressed to AC3 i.e Dolby Digital.

Anyway, Pixel, recording to DVD-RAM is ok, but can be time consuming. There is also the fact that DVD recorders write to RAM disks slightly differently than they do on DVD-R. When recording a DVD-R , the universal DVD standard is followed and a VIDEO-TS folder is created with a VOB file for each recording. But when it comes to RAM, it's slightly different. Even if you have several separate recordings on the disk, they're all merged into one file with the file extension .VRO. You can dump this file onto your hard drive and change the extension to .mpg and Windows media player will happily play the video files, but editing them then becomes awkward. Initially I was stumped because I couldn;t find any softwear that would accept this new file type, but I discovered that TMPGEnc (mpeg tools) and TMPGEnc DVD Author have absolutely no problems using .VRO files.

My way maybe the long-winded way, but I usually use TMPEGEnc DVD Author to edit out any footage I don't want and then use it convert my VRO files into VOB files. This way, neither the audio or video are re-encoded so there is no loss in quality. I then use TMPGEnc to Demux the MPEG and AC3 streams from eachother and then author my DVD's using DVDit PE.
I had read somewhere that using the editing suite on the recorder to chop out unwanted material can lead to sync problems down the line. So to be on the safe side I always use TMPGEnc DVD Author to edit what i don't want out.

Hope this helps

thanks for the info uklad24, I might look into that (I would have to buy a new DVD ROM drive though).

I knew they were saved in .VRO, but I didn't know TMPGEnc could edit them because people have complained about them in the past.
