High resolution screen capture format software#
You can do that with softwares like Adobe Premiere or VirtualDub (this one is highly recommended - get it at the software session of However, that resolution demands a lot of processing power and free disk space. If you want your capture to look just like the VHS source (unfortunately it can't look any better), capture at 640x480 at 29.967fps, and then DEINTERLACE it. On the other hand, if you compress a VHS source video at the same resolution, the noise will seem to be amplified, and will take a lot of the stream bandwidth. If you compress a DVD ripped video at 352x240 with divx, you get a good result, because the source video didn't have any noise. There's also a great difference between videos captured from a VHS source and the ones ripped from DVDs: the noise.
The same effect (defect) will show up arround hard edges. Just like a jpg picture with high compression.

When capturing a movie that has subtitles or any small text with the standard 352x240 resolution, you'll get those little "ghosts" all arround the text when you compress it to a higher compression system, such as Divx -). If you have enough free space and you HD can keep up with high transfer rates, use uncompressed formats. Also, if you are going to recompress that video later, or if you intend to edit it, try to capture with the least compression you can. So, even if your video source has a very low resolution, you should capture it with at least 320x240, or the results will look weird. The smaller the resolution you use, the bigger the aparent size of those blocks will be. Compression algorithms (ie: Divx -) or intel indeo or ATI's VCR1 and VCR2, etc.) break the video color information into 16x16 pixel blocks. THE COMPRESSION ARTIFACTS:Īnother interesting point is the compression you use. If you capture at 352x240 or 352x288 you'll be skipping every second field, which results in only half of the resolution. You can find more information about this in the articles session of Those two fields mean that every frame carries much more than just 240 or 288 lines of information.

In fact, every frame of an interlaced video is divided in two fields (the reason for this is a long story that comes from the first TV sets. The VHS video works with the interlaced system (not progressive), which means it draws every frame twice on the screen.
So all those documents were wrong? No, they were inaccurate, or maybe just incomplete. You capture with that resolution and you get a video that looks like shit. If you search through the internet looking for information on the VHS resolution, you will find basically 352x240 at 29.967fps (Frames Per Second) for NTSC and 352x288 at 25fps for PAL-M. Any damages caused to your system by the procedures suggested bellow will be your problem, not mine. This is provided just a a guide to help you with your captures. Talking about risks, I will take no responsability about the procedures described in this document. LEGAL STUFF:īe aware that you MUST have the rights to make a copy of any copyrighted material, such as movies or video clips. I'm no expert in digital video, but I've been through the painfull process of chosing a resolution for my captures, and I'll share my experience so you won't waste all the time I did capturing and compressing over and over.
