Lossy 704x480 vs LossLess 352x480 for capture

Have you ever thought about capturing 720x480 to DIVX 5.1 1 pass at 4000kbs or higher? Force a key frame every 30 frames (1 second) if required for editing. If you have the CPU power, it works very well. Regards, Owen

hi vmesquita, As too the flaXens VHS (FVHS) and all, I forgot to mention that I too have experienced it operating a bit slow. FVHS though, has proven to be a worthy contender to the other more up to date de-noisers around. However, I've become a bit rusty, as I've moved on to other time-consuming projects (and their issues) that continues to cause me much drain in my processes :( To get back to snup, I will usually re-capture my best projects and re-learn what I've done, in hopes I remember those settings I used in FVHS. But, again, to me, the slowness was worth it in those VHS projects that I've done in the past. Some of them were done w/ my DC10+ card, which is (imo) great for VHS projects because of the lack of Noise :) in the source AVI file.. and if memory serves me, I use FVHS on the Bug's Life project I mentioned earlier. ie, I remember having problems w/ the scene where the BUGS (grasshoppers) dig down through the ANT's chambers, and how the head BUG was bossing the ANT's around, and how a Light was shining over him in one scene, and as he moved closer to one of the ANT's, you could see the light bleed through the other scenes. This gave me such trouble w/ FVHS, till I figured it out (for that clip) anyways.. me ranting on a past project :) Now, I have my own set of problems going on w/ something I'm working on in DV :( FWIW, I have found that for VHS (imo) it's best to use filters in a minimal capacity. Because you need as much detail as possible w/ such a low source of resolution (aka, VCR spec) That's why I choose FVHS for my VHS projects, and skipped the others. Well, like i said, FWIW and all :) And, also I learned that CQ can really help (another imo) in this VHS processes. I think that w/ multi-pass, there is a limit to the bitrate in some scenes. But, I can't be 100% sure, however. I use CQ in any case for these (and all my other encoding projects) Whatever you decide to use (all or one sigle scenario) I'm sure you'll make the best use of it/them in your VHS endeavors :) Yeah, I've got some 8mm tapes laying around that needs to be done, but I need to first get my old 8mm cam fixed (all my tapes give me the BLUE SCREEN of death :mad: and I can't get one shred of video to view on my tv (or camcorder for that matter) Anyways.. Good luck w/ your projects, -vhelp

I need a final video with 512x384. All my capture are anime VCR. My video card have a bad driver (Pixelview Play TV PVR) then I need to capture with 480 vertical resolution. I think in two capture scenarios: 1-) Capture with MJPEG 512x480 at Q19, then resize with lanczos filter to 512x384 2-) Capture with VBLE or Huff 352(320)x480, then resize with lanczos to 512x384 The second method result the biggest file size but it's still in my hard disk capabilities. Which scenario give me best quality of final video? Remember that my source is VHS ANIME! I hear that anime is not good to MJPEG because the edges.

I would make some tests with the different options and compare the results before making a final desition. You can make some short sample clips or your source and compare the final results. I think the results will be different with different video sources. But the best advice is to buy a larger hard disc so you can avoid the disc space issue and allow yourself to use lossless capturing at higher resolution.

I did some tests yesterday and my conclusion is: The test: 1-) Lossless 320X480 with lanczosresize 512x384 2-) Morgan MJPEG 98% quality 512x480 with lanczosresize 512x384 Method 1 gives more blur image. Method 2 gives worst PSNR (1db less). Method 1 gives best visual quality Method 1 gives average quantizer 3.8 and method 2 4.5 Method 1 is 220Mbytes/minute and Method 2 is 165Mbytes/min As as suspect, MJPEG is very bad to compress anime and I think this is the reason for this results. I am not sure which is best and I will try more videos.
