Video Degradation in Vegas
I have been capturing videos from console video games. I use Edius Neo and the Canopus DV Codec (AVI) which came with the wonderful Canopus card I searched so long for. It captures the videos exactly the way they originally looked while the game was being played.
My problem is this. If I edit segments out of those videos Vegas seems to actually be re-rendering the whole file even though I am using the exact same codec, and the result is a video not nearly as clear and sharp as the original. I know that when you edit video generally the quality goes down, but not only is this a very good codec, I’m pretty sure the frames are each independent. Couldn’t Vegas or some other program just cut out the frames I’m trying to get rid of without processing the whole thing.
As I was writing this it occurred to me that the Canopus Card Captures at 720×480. Then in vegas I set the Canopus DV codec to 720×480 in the custom screen. If my project was set to 640×480, would that cause the blurriness? I doubt this is the case, but I’ll test that out while I’m waiting for an answer. I have included the snapshots of the videos taken on VLC media player.
Thank you all so much for your help!

Okay I did not read the instruction last time, so my pictures did not attach. Here they are. The first is from the original capture the second is from the edited capture. A horrible change!

Justin,
VirtualDub, https://www.virtualdub.org/, will allow you to cut out pieces of the AVI file you do not want (and lots more if you want).
Once you start VirtualDub and select your input file, make sure you select Direct Stream Copy in the Video and Audio menus. Using direct stream copy, no compression/encoding will take place when you save the file.
You can mark in/out ranges on the timeline at bottom and hit DEL to delete sections, then just File -> Save as AVI…

Thank you!
I’ll give it a shot.Just out of curiosity, is this direct stream copy something that can be done in Vegas? And if I research that general concept online is “direct stream copy” the wording I should use or is there something more universal it’s also called?
Thanks again.

I have only seen the terminology used in VirtualDub, and do not know if what you ask can be done in Vegas or not (I use Vegas Movie Studio 9, which does not have all the features of Vegas 8 Pro).

I tried it and compared screen shots to the original and they were identical! That is a must for me. I’m trying to make tributes to some of my favorite older videogames and I already have about 800 GB of video. I’ve meticulously worked out each step of recording and protecting the captures. This was the last step, and you have helped me solve it much faster. I wouldn’t have even known which question to ask a search engine. It would have taken me days.
So thank you very much for the time you have saved me, and for giving me the perfect solution to my problem!
