Cropping and bitrate loss

Newbie alert! I'm still learning about the TVS features, so if this has already been covered, I apologize.

Most of the content I record from prime time is 16x9 in a 4x3 frame. I'm recording SVideo from a HD settop box.

So, this feature of cropping the video seems very appealing. But when I do this, the recoding is making the quality of video about half of what it originally was. Original bitrate ~6Mbs and DVD has just ~3Mbps.

Is this a function of the over-compression in the algorithm that I've read about in other threads? Will this be addressed when the algorigthm is updated?

Thanks.

Yes. Please read the whole thread about increasing the bit rate by lowering the Constant Q parameter on the Shift+Tools>Options.

Hi again,

Still seeing the same problem.. I set the "Recode initial quant x 100" to 100 from 400, but I still get the same results.

Is this the thread to which you are referring?

I also set the Tools>Options>DVD Settings>Recoding speed to Best (slowest) and the bit rate went up only slightly.

I must be missing an obvious setting, I suspect.

Hi I record exactly same as your.

I use 9.50 Mbps - HQ in Video Options. No loss quality. ( To prevent loss quality ) Then I goto NERO for DVD Burn thing. Perfectly :D

I have not burn to DVD by TV Suite yet but it look very good in folder.

I love this Crop by TV Suite. Successful for me.
