Solve : Video Conversion Tape to Digital Questions? |
|
Answer» I am using a Audio/Video Capture device to convert old family videos from 8mm and VHS to Digital and have some questions ( mainly how to preserve quality and also have the size as small as possible ) Analog Video Capture to Computer The DV option makes for insanely large videos almost as if the data is RAW like fraps type of videos. MPEG-2 is probably the best option from what is available. Ok.. now for questions: 1.) Should I try to find a different data sample rate which I am guessing the 6Meg setting is for the MPEG-2 preference or should I be recording in a different format? 2.) Should I create these videos with DV instead of MPEG-2 and then use VirtualDub to compress them to h264 or some other better sized and hopefully minimally lossless format? 3.) Should I take the 5.5GB MPEG-2 videos and compress/encode them with VirtualDub to a better smaller and hopefully minimally lossless format, if so what is the best to work with for the format and settings? 4.) Should I save these as DV or another format and then use some other toolto make them smaller other than VirtualDub? 5.) Is 6Meg datarate for MPEG-2 format of VHS and 8mm tapes overkill since its far from High Def, and if so what data rate do you feel is best to go with before I start to notice a loss of quality? (*Obviously I could just record samples at different settings and compare, but figured I'd post this in case anyone knows the setting is which anything greater than a certain datarate just makes for wasted HDD space? ) --------------------------------------------------------------------------------------- Also just wanted to state that if anyone has or is thinking about BUYING one of these, the CPU processing power is important!!! This device works way better than the prior EasyCap device I had. The EasyCap I wasnt very impressed with the quality of it since there was loss in quality from VHS to Digital etc, so it got set to the side. But I found this device with better feedback for capture quality and bought this a few months ago and finally have time to use it. I tested this on a spare system I had with a comewhat modern Sempron 140 2.7Ghz single-core with 2GB RAM running XP Pro SP3 and while it did operate and run this software and capture device over USB 2.0, I was finding that there was at the bottom of the video capture software a frame COUNT that was climbing. It stated that the affected frame is placed behind the other or something like that and I was like ok, maybe its a buffer for frames and it will assemble it all in the end. Well in the end of recording 2 hrs of video I played the digital video file and the family video started off ok and then within about 3 minutes I saw that there was a timing offset between video and audio where the mouths of kids and family members at events were mis-timed. So I then went and installed the software/drivers to my better AMD Athlon 4450B dual-core system with 4GB RAM running Windows 7 64-bit and ran this video capture and there was 0 frames added to this frame misplacement counter I guess it is, and at the end of 2 hours the video was perfect with audio/video timing. I jumped ahead to the end of the video vs watching the whole 2 hrs of it, but on the weaker CPU system it was a problem that started small and was more obvious later in the video. So I assume that the content in between is perfectly timed as well. Thanks Did some testing and right now it seems like 3mbit's for MPEG-2 is where a quality of picture for video is noticed from the original and 4mbit's for MPEG-2 audio/video capture does not appear to show a degradaition between original video and the VHS ot 8mm tape. So I DROPPED it to 4mbits and it made for smaller video files. It would be nicer if I could get them down to around 1.5GB per video without loss, but right now it looks like 4mbit MPEG-2 videos are like 4.3GB in size for 2 hours of video. I guess I will be capturing these at 4mbits for the VHS and 8mm tapes. Maybe the higher setting is needed when working with better quality recordings to avoid loss. If anyone has any suggestions on how to get the file size down further without loss I'd be interested in which format and/or tool to use to do so.
