View Full Version : A question about resolution.

This is my first time using Gnot, and I'm wondering about the resizing part. I've been reading Doom9's guide about encoding with Gnot and experimenting a bit. The guide says that I should use Auto resize, and then smartcrop. Is it possible to set the exact output resolution manually?

What are standard resolutions for a 16:9 DVD-rip?
I encoded my first DivX directly with Vdub, and set the resolution to 704x264 on a 16:9 DVD-rip.

I can't see that the picture is streched or compressed in any way, but that may be because the error is small. I've seen it 640x272 too and it looks ok. Comparing the two ASpect Ratios I get:

704x264 ----> 2,67
640x272 ----> 2,35

Original DVD though is 740x480 -----> AR: 1,54

Even though I can't see the difference when I watch them, the ratios are all different, and both Divx AR differ from the original.
Should I for instance choose 704x448 -----> AR=1,57, that's the closest value divided by 32.
Or a smaller: 640x416 -----> AR: 1,54 also divided by 32?

Are these resolutions ok? Or have I completely misunderstood it?

Are there some guidelines when choosing resolution?

I am thankful for any help I can get.

Hi-

Yes-You've completely misunderstood. Forget the DVD AR-It's stretched and gets corrected when played. Follow the GKnot Guide and you'll be OK. However, I'm not sure I trust the Auto-Crop. I usually cut off the bars with the Pixel Crop and then Smart Crop Left-Right. And you won't come up with 704x264 that way, which is probably slightly off and not divisible by 16.

Also, run the Compression test to help choose the resolution, as your preferred resolution may in some cases be too high to produce a good movie, particularly if going for a 1 CD rip.

And welcome to the Forums.

I'll have to try it out.

id really suggest u use divx502 (and ogg for sound) as i am really impressed by the improvements over divx311a and mp3.
back then i could only put an 90min movie with one language at 704x... resolution on 1 cd, for longer movies i had to reduce the resolution. now i already did some 110min movies with 2 languages with this resolution, 90min movies dont even reach the 700mb in this way!
just try it! (ogg quality at 0.05, divx with gmc, b-frames and psyvis strong)
