Unable to record HD back to tape on Canon HV20

[Georg]

I don´t have a HV20 but I test it with my Sony HC7. In the first try it doesn´t work. Then I change the firewire on the HC7 from automatic to HDV and it works. In both times the HC7 shows in the display "HDVin". So can you change the firewire-connection?

After much experimenting and failure I have found the answer to the problem of 'Transferring High Definition video from VideoStudio 11.5.0157.2 plus to the Canon HV20 Camcorder Sony HD tape'.
Go to 'Share' - ' Create Video File' - AVCHD H.264 (1920 x 1080, 25.00 fps) - the video is now rendered (lengthy process) - The clip now appears in the Library - Highlight the clip - Go to 'HDV Recording' - HDV 1080i,50i (transport stream PAL) (60i for NTSC ?) - 'Save' the file which is now rendered for output - Go to 'HDV Recording - Preview Window' - 'Next' -press the red button - The message now appears 'The video is recording to the HDV camcorder' - Press 'Finish' and your edited project is on HD tape. Hope that this does not sound too complicated. Best wishes, Delcole.

Thanks Georg for the information but unfortunately I cannot read German but as you see I have finally overcome the problem. With very best wishes, Delcole.

Delcole,
Your post may have worked but I recommend trying not to re-encode your HD videos so many times. Your workflow bypasses a smartrendering process by converting to avchd (another format)and then back to HDV, not to mention your changing the framesizes and performing a complete re-encoding of the video twice. That must have taken along time to perform.
.
HDV on our consumer cams tape is 1440x1080i, Mpeg2@25MBS CBR, strict compliance, it is in Transport Stream format.

Try this, load or capture some HDV from your HV20. Right Click on the video and select Properties, view the videos properties, even write them down.
Your framesize should be 1440x1080 Upper Field First 25000kbs (CBR), 25fps & mpeg audio. The HD video is in PS (Program Stream) format. VS11+ converts the video from TS (transport stream) to PS (program stream) during capture. While on DV tape the video is in the TS (transport stream) format. To write back to tape the video must be in TS format and strict compliance with the HDV format.

Now goto "Share -> HDV" and View the selections that are marked HDV. Select the HDV 1080i - 50i (For HDV)
In the next window look at the bottom left of the screen at the "Properties" VS has selected to encode this video at. Notice it says (Transport Stream).

Now go back and again "Share -> HDV" and select the HDV 1080i - 50i (For PC). Click OK and In the next window again look at the bottom left of the screen at the "Properties" VS has selected to encode this video at. Take notice there is no (Transport Stream) wording, because that setting is PS (Program Stream) format..
VS11+ captures in the PS format. To write back to tape it has to convert the captured PS formatted video back to TS (transport stream).
To make use of VS11+ smartrendering of HDV video it works best in the PS format. So since your video is already in the PS format, then to create a new file using smartrender your would select the HDV 1080i - 50i (For PC). Test this and you will see how fast VS11+ can copy the unedited parts of your video to a new file.

But to write back to tape the video needs to be in the TS format.
So after you have captured some video, to write it back to tape and have it work you goto "Share -> HDV Recording -> OPTIONS and UNCheck "Perform SmartRender". With Smartrender checked on my writing back to tape has glitches, pauses in it. So, probably a smartrender problem.

etech6355. Thank you very much indeed for your prompt and detailed answers to my problems. I have made a short project and the results are perfect when using your instructions and also shortening the time taken considerably than in my prevous efforts. Again with very many thanks and kind regards, Delcole.
