i was curious, is the quality of a SBS mkv file a good representation of 3d?


for example if i compared the 3d (SBS file) to the retail 3d bluray, would there be a difference is picture quality when it comes to crosstalk?


would crosstalk be worse on SBS mkv files, or would the crosstalk be the same as the retail 3d bluray disk?


or is it strictly related to the tv?

Normally, the only downside to SBS is a halving of the resolution. If crosstalk worsens in SBS, it's the result of a design flaw in the television's processing. Some TV(s) last year had this issue.

ok thanks cake. so lets say im experiencing some crosstalk on a SBS file, that means i will experience that crosstalk on the retail bluray also then right?


some files i have look pretty awesome, "how to train your dragon" doesnt look that good, but i've read here that others with the retail disk say it looks great.

I can't comment on your TV- the only way to know for sure if your TV is handling side by side properly is to get 2 different versions of the same movie to compare the crosstalk.

I would prefer 3D blu-ray to SBS format. There is a loss of PQ quality in sharpness compare to real 1.4 frame packing 3D format. I'm using Acer H5360BD, a 720p 1.4a HDMI compatible projector. I don't observe any crosstalk issue with either format.

I have a 18 gig sbs copy af avatar that looks incredible has a dts sound track also I can't tell any difference in it and any blu ray frame packed disc I have. I just think it just depends on the quality of the rip. Only thing I hate is I can't fast foward or skip chapters in it. So to demo it you have to sit thru the first 30min to really get to the good 3d part

I agree here. The size of the file relates to the quality. The larger the file the closer to the original.

Isn't that a DLP projector?

Yes. H5360BD is a DLP projector. Regarding the 1080p SBS Avatar, I do agree that the higher the bitrate, the better the quality but still there is a difference between SBS and full ISO or dual left and right mkv format. I had compare Avatar 18gb SBS format compare to blu-ray ISO and it's definitely sharper on ISO. Screen size and seating distance might be one of the factor.


I also compare ISO playback using a HTPC with TMT 5 and Oppo BDP-93. I do feel that Oppo had a slightly better PQ compare to HTPC. My only problem with Oppo is no support for ISO over network.

What are you running the side by side through? If it's the VIP theater your getting 720P not 1080P. Agreed file size is important for quality.

I'm using 3D Vision Player with ffdshow to resize 1080p SBS to 2560x1080 and output at 720p 120hz. I try native 1080p SBS to the projector and use the projector build in SBS 3D format but it looks less sharp compare to ffdshow resize. Maybe Acer H5360BD scaler is not that good.


FYI, H5360BD is a HDMI 1.4 compatible projector and support frame packing and SBS format natively without external 3D converter.

Does the VIP Theater need to be recalibrated (for delay and duty cycle) every time the SBS movie is paused or if you skip to a new chapter?


I don't really understand how the Theatre keeps the glasses in sync. When the movie is paused, does the shutter glasses also pause?
