Rendered with Sony Vegas, but then architect pro has to decompress. why?
Hello everyone, this will be my first post. I see this forum site the most when I was doing my homework on the ins and outs of video capturing, editing, and rendering. With still some little questions that I couldn’t find answers I decided to register and make my first post.
Here is what I’m working with in case I had to post it
CPU – Intel i7 2600k

https://www.diamondmm.com/6870PE51GV2.phpI’m using the black magic intensity pro. The online resellers recommended I go with it because of the compatibility issues with the shuttle and its 3.0. I’ve been editing and rendering with Sony Vegas Pro 11. Before I used to capture and burn VHS tapes to discs with the dazzle from Pinnacle. Quality was poor but I guess that’s what you can expect from composite capture. I’ve done some editing with live source like on the Xbox 360 and had fun with that but now I’m working on a job for my coworker, to record and burn his old VHS tapes onto DVDs. What I’ve been doing now is capturing with black magic media express, cutting out static and useless clips with Sony Vegas, and then rendering as MPEG-2 and under that with DVD Architect NTSC Video Stream so that I can take that to DVD Architect Pro 5.2 and burning to a disc.
So my first question is which is the best file capture format to use in my case of capturing video from VHS? I can handle uncompressed because of its large size, but if I do go with it do I choose AVI 8bit, AVI 10bit, or DVX? And then of course there is compressed AVI Motion JPEG. What I’ve experimented with so far is AVI 8bit and it worked pretty well. I fell asleep with the VHS on, tapes are usually 6-8 hours, and some of his tapes have multiple events, most usually an hour long. This tape had about an hour of footage, but of course I recorded for about 8 hours so the file size was about 600GBS. I clipped the empty footage, and rendered to DVD Architect NTSC Video Stream under MPEG-2 and was left with a 4.9 GB file. This rendering process took about 30minutes. Next I imported it to DVD Architect Pro 5.2 and had to optimize/compress it because the file size was too big for the 4.7gb dvd-r, it took about 90minutes to render this and about 20 minutes to prepare and burn which leads to my second question as to why did this take so long? Is there a way to render in sony vegas so that I wont have to go through this? When recording on the dazzle, editing then burning with pinnacle would take maybe an hour tops, where doing things with the intensity pro took about 2.5 hours I was confused as to why doing the same thing pretty much (except rendering with Sony Vegas) would take about an hour longer. I appreciate all and any help.
Cheers, John

As far as rendering the MPEG-2 so DVDA doesn’t have to re-compress – you’ll have to experiment with different bit rates depending on the running time of your show vs. quality needed. Once you choose the DVDA template as you’ve don, you can further customize the settings such using either CBR (constant bitrate) or VBR (variable bitrate), 2 passes (which won’t increase the size but can increase the quality on certain scenes) and there is a quality slider which I usually leave on High.
You’ll notice under both Constant and Variable you can type in your own bps values. If you choose Variable – try setting the max to something like 7500, Avg. at 5,000 and leave Min alone. You can experiment with these values until you get a file size that easily fits on a single layer DVD. Your audio can also effect file size – use separate Dolby Digital AC3 at 192k.

Thank you Lance, i didn’t know how to get a smaller output file size without dramatically decreasing the quality in any other setting. Tried what you recommended and went from 4.79Gbs in the first rendering down to 4.08Gbs with the adjusted variable bit rates. Only noticeable difference is a small decrease in sharpness and color is a bit lighter but ill experiment with the variables. Would you recommend variable or constant or is there anything i should know about when setting these?

I usually use variable as it will adjust bitrate automatically based on the complexity of the scene. If you have a show with mostly static shots or talking heads, CBR is fine.
