S-Video to ADVC-100 to DV In on DVD Recorder

[jrank001]

I would like some opinions if the picture quality would be better if I captured from a Sony CCD-TRV118 Camcorder s-video out into a Canopus ADVC-100 then out to the DV in on my Toshiba RD-XS35? Or should I just use the s-video out to s-video in on the DVD Recorder.
Thanks

I would connect you camera directly to your recorder as there will be less format conversions...

In theory both paths would produce the same result. It would be interesting if you could record the same clip (e.g. a SMPTE color bar) both ways and compare the result.

If you use the ADVC-100, make sure its IRE switch is set to 7.5.

Thanks for the input.
edDV I’m new to this and I would like to do the comparison but I don’t know how using the color bar you suggested. At this time I’m having some audio issues using the mini jack A/V out on the camera. I think the A/V orifice is damaged. Checking that. Will make sure the IRE is set to 7.5.

The ADVC-100 can output its own analog color bar. You can use it to calibrate your VCR. Record the color bar to the VCR and capture the color bar playback back through the ADVC.



If the VCR and the rest of the path is at proper levels, the capture waveform will look like this. If you have a waveform monitor you can evaluate levels and the various sources of noise.

I think you will find connecting the camera's s-video output directly to the DVD recorder will yield the best results.

The RD-XS35 has a very good TBC/Frame Sync/video processor and you can also use the unit's input (recording) DNR video noise reduction if you like to clean up any Hi8 grain and chroma noise prior to encoding to DVD compliant MPEG2. The video image quality of the XS35 recordings is outstanding.

For hand held camcorder footage, always use the highest quality bitrate setting (will allow 1 hour per single sided DVD-R) and there will be virtually no motion artifacts (macroblocks, etc.)

The test for the RD-XS35 for both paths would be:

1. Record the color bar ADVC to the VCR.
2. Play the VCR though S-Video directly to the RD-XS35 and record a clip.
3. Then play the VCR through the ADVC and record on the RD-XS35
4. Evaluate the resulting DVD MPeg2 visually and with computer analysis.

Thanks edDV. I will give it a go and hopefully get some interesting results.

Gshelley61: Would that setting then be 9.2 on the Toshiba RD-XS35 for one hour recording or5.6? I am looking at page 164 recording duration under DD1(192kHz).

Gshelley61: I think I figured that out after I posted. The book is not much help.

Has a test been done comparing the RD-XS34/35's noise reduction to the JVC DRM-10/100's noise reduction on a very bad grainy vhs tape?
